Global Warming Experiment #1

(I slightly changed the instructable into a forum topic and an instructable)The Instructable Half"Global Warming" Experiment #1:As you can tell by my quotes around "Global Warming", I personally don't believe that this theory is happening. Theres facts I can use to prove this. However, even I believe that no matter how you put it, there's going to be some bias. Also facts are boring :PSo, what I have planned, is to do a series of experiments on what global warming might cause if it were real.I'm doing this because I've heard people claim some extraordinary things, which based on data won't happen.I could post an instructable with a bunch of facts, and I might. But for now, I want to set up a couple collaborative experiments. One reason I want collaboration is I'm biased. The other, is so you can't complain about my methods.I haven't done the experiment yet, I really don't know if this will help, or hurt, my case.The experiment is to determine if "global warming" could melt glaciers, thus cooling the ocean. Notice here I'm assuming global warming is happening. It isn't. But when people make claims on the news and stuff, they are assuming that too.Please comment if you would like to change my methodology, OR you want to do the experiment.I'm going to describe how the Instructable (and hopefully the rest in the series) will work.1) I, or anyone, proposes a framework for an experiments and writes up an Instructable. (Will be referred to as "I" in the following steps)2) I monitor the suggestions, editing and fixing as needed. After about a week or so, I go onto step 3.3) I preform the experiment to the best of my ability, and write up an additional 2 steps.3a) The first outlines my changes. This could mean I didn't have a 4x8 loaf pan, and I had to use a 3x8. Or it was plastic. Whatever. These small details are important3b) The second outlines the data and conclusion. This may have images of the experiment, graphs, tables, sensor data, Whatever. I also make a note of my previous bias.4) Wait for more people to run through the experiment, adding them as collaborators.5) Write up a conclusion to everything, OR do some more investigating.Its not that bad, however the whole process might take a few weeks. (I don't know)Scientific MethodThere are seven steps to the Scientific Method, which we will follow:1. Define the question2. Gather information and resources3. Form hypothesis4. Perform experiment and collect data5. Analyze data6. Interpret data and draw conclusions that serve as a starting point for new hypotheses7. Publish results(Thanks Wikipedia!)#1 was done in the introduction.#2 I've already done, however you only have to look into data you'll need during the procedure.#3 I've done it, but I'm not telling you (I don't want a bias, even though I've hinted towards my guess)#4 - We're going to expand this out. More later!#5 and #6 sort of come together in this format, will be done as we go along.#7 is done as we go!Okay, #4. Remember back to High School, remember Lab Reports? Well basically there will be a step for each segments (leaving some out). We sort of do this already in most instructables "What will happen", "What you need", "How you do it"; this time more formally. Due to Lab Reports being unstandardized, I'm breaking it down into:IntroductionMaterialsProcedureDataIts shorter than your average one, due to the fact in Data, you have hypothesis and stuff I don't want to reveal yet ;-)The following is the framework, you can also see my instructable:(This is a framework, remember. Its not supposed to be "done" and perfect)Materials*Large basin of some sorts.*Water*Ice*Lamp + Light bulbs (100W & 40W)*ThermometerProcedure1) Fill large basin/pan with water.2) Take and record standing temperature of water.3) Add ice off to one side of the pan.4) Take temp. of water every five minutes until it starts to level out, at least 4 readings.5) Replace water, and repeat steps 2&36) Shine lamp w/ 40W bulb off to the non-ice side of the pan, but allowing some light & warmth to reach the ice. (Roughly 20-35%)7) Repeat steps 4&58) Repeat step 6 with a 100W bulbTake pictures throughout!What now?Okay, I'll be updating this with your comments over the next week or so. If somethings wrong with it, POINT IT OUT!!! I'm going to add my thoughts in as well. (I still feel its missing some things, I can't put my fingers on them, though!)

Super cooled Water

Hey all, I wasn't able to find where a short discussion about Super cooled water was posted not long ago, and I wanted to relate this incident; so if I get no replies, that is ok. I just thought it was kind of neat the way this occurred. Last night, well, I guess it was actually this morning ( 00:30 ), I left work and went to my car, got myself situated, and before driving off, I grabbed a bottle of water that was in the cup holder. I distinctly remember shaking it to make sure the water was NOT frozen. I also took note that the bottle was partially imploded; something I would have expected as the temp was down to about 17 o F. When I opened the bottle, put it to my mouth and tilted it, the unexpected happened. Between the moment of releasing the vacuum that had formed and my trying to drink from the bottle ( about 3 seconds), the water froze to a Slushy consistency. For a moment I was perplexed why I was getting no water in my mouth, and then it slid from the bottom, and it stopped at the neck of the bottle. I had forgotten that this could happen. I must have sat there looking at it for a good 2 minutes trying to get something out of the bottle, when I thought I would blow some warm air into it. The bottle inflated slightly, and the air passed by the slush, and when I released, I got a face full of slush. I had to laugh at myself all the way after that little incident. :-)

can i power a warm water geyser with 8.10 v?

am brand new to electric and electronics, i know very little. the motor (gemini gate motor) tested on a bench with a drill produces 8.10 volt. so what i need to do now is step up the volts to 13 or 14v so i can charge batteries, then build a small inverter to step it all up so i can power a geyser for warm water. in my naive state i tried to measure the amparage through the motor and s i connected it into the circuit it produced 3.5 amps so what i think i have is a 8.10v motor (peak rpm) with 3.5 amps which i have to make power a warm water geyser.

Cheapest Solar Water Heater and Cooker needed which can keep the water warm for a few hours

I have read many of the instructables about hot water heaters. I am a person living with a really meagre salary so can not afford to find or buy things like refrigerator backs or car radiators. Even though, after having read all these instructables, I have a need as well as a wish to have some kind of water heater that can atleast warm the water in cold / rainy weather to a level which does not feel cold. Something ofthe body temperature level or warmer will do. AND after warming this water, it can be kept for a few hours without much loss in the temperature. Quantity could be like 10 liters or so. Any help most appreciated. The instructable using cold-drink bottles is a nice one but the quantity of water is very small so can't be used for bathing / washing etc. I'm also looking for a solar cooker with very low costs, which is able to cook rice in about 2 hours time. Any and all help greatly appreciated. Thanks, RS

I want to build a kitchen warm-up water diverter, but I don't know how.

I want to divert the initial cold water when I run my kitchen faucet (to get hot water for dishes, etc.) through a pipe or hose through the kitchen window outside into a rain barrel, and to be able to route that water out to the birdbath to fill it in the winter from indoors, or to water the yard in the warm months. The faucet is way higher than the patio outside, and the patio is maybe 6" - 10" higher than the birdbath so I'm thinking gravity will do it. But I don't have the know-how to construct such a system. It would have to include somehow sealing around the hose leading through the window, as we have cold winters. Therefore I would probably have to address the water freezing and plugging the hose outside.There is an electrical outlet on the outside of the house so I think I could wrap a warming blanket around the hose if necessary. Any suggestions? I have limited tools and skill, but a lot of time and patience. :)

Battery powered water - warmer / Thermostat possible?

Hello. I am looking to design an enema kit that has a simple built in battery powered thermostat.  I work with many patients with chronic pain & opioid induced constipation.   They use warm water enemas often to clear their bowels.  The number one complaint i here is "its too annoying to get the temperature right ' So i was thinking, how could i design a simple design.    It would have to be able to heat 1L of water up to 37-43 Celcius and be battery powered.   So a patient would fill up the 1L enema bag with water, hangit up an turn the heater on with their selected temperature.   THen an alarm will go off and they can administer it with the temperature stable.  So i guess what im asking is it possible to get a battery powered thermostat for this purpose?   If it needs a plug it won't be convenient enough. Thanks heaps!

Hello everyone, is it possible to boil water from room temp (20C) using regular batteries? according to my research, to warm up 500mL of water by 10C within 10 minutes, it will take 1 battery (3.7V 3400mAh).

Proposed Evaporative Air Conditioner

Have an idea for a Evaporative Cooler.  In most conventional coolers a fan pulls warm air through a panel that is constantly soaked in water, the water pulls the heat from the air.  Another form of this system is the simple "Mister Jets" that spray a fine mist into the air which pull the heat from the air dropping the temperature.  My idea is a combination of the two... See Image. The concept is simple... - Fan pulls warm air in and forces it into the body of the cooling unit. - A mister sprays a fine mist that combines with the air pulling the heat out. - To remove the fine air molecules a synthetic membrane (like pond filter material) is used to collect the vapor and allow the air to pass freely through. - The resulting water will make its way down the membrane and drip into the water basin below. - The pump will then recirculate the water back through the system. Seems like an easy enough system, the only problems I can see are... - Mildew - Leaks - Filter doesn't remove all the water So let me know if you guys think this will work.

Where is the induction kettle or hot water system?

No modern kitchen these days is complete without at least a single induction cooktop.Convient to even place on the table to keep things warm but also nice to have 4 or 6 "hotplates" to cook on that are actually not getting hot at all.When it comes to efficiency induction cooking tops all others as no heat is wasted.Which brings me to the point...A single cooktop goes now often for well under 50 bucks.Although the base might end up slightly higher than a normal kettle I fail to see why we don't have induction kettles in our kitchen.Why wait 12 minutes to have the thing boil if you can do it cheaper and faster?Way more convinient too as there is no pesky contacts and heating elements anymore, no failure due to leaks either...But what really got me wondering is the hot water systems or heating options like prefered in Europe.Here you have a central "boiler" so to say and water circulates through valves into finned radiators, usually located under windows.We have oil filled radiators of this kind as free standing units that are now being phased out because they waste too much energy with their heating elements.Same story for just hot water :(On demand systems are getting more popular now outside Europe but still the common solution is to have a few hundret liters of water in a tank that is kept hot no matter how much of it we use.Be is gas or electric both types have their drawbacks and to get ahead of the corrosion that always kills them we now opt for expensive stainless steel tanks...Using induction it would be very easy to have a fully sealed tank and to actually only heat what needs to be heated without wasting too much energy.The "heating" element could be just a steel plate inside the tank with no connections to the outside.The gap between wall and element doubles to make the water circulate.And changing from a fixed timer to a temperatur control system to turn the induction element on and off is not hard either.Do you have an induction based hot water system, heater or maybe kettle already?Would love to see it...

Where can I find a/an (ideally black) watertight fabric that could be used for a solar water heater?

I'm in sunny New Orleans, and we are encountering a ridiculously cold snap.  I don't keep my house too warm, so I'm dying with electric heater cost.  Since I know my windows are one place where a lot of solar might be collected, and energy is lost, I am trying to find a way to collect passive solar energy. The idea is to sew several tubes into watertight fabric in a design like a radiator, and then fill them full of water.  The idea is that this will absorb the heat from the sun and then, as night falls, act as insulation against the cold.  And I am hoping that I could hang them in the windows of my house and remove them when it warms up. Does anyone have a suggestion for watertight fabric that I could use for such a project? Thanks D. Adrian

Loss of temperature sensation in fingers? Answered

I've never had this problem until now...here's the story. Well, I was outside the other day, and it was freaking cold out. Probably about 9 degree's F. I was wringing cold water out of a towel (long story) and the cold really hurt my fingers. First my fingers felt cold, then nothing...just this buzzing sensation. Realizing that wringing water out of a towel with bare hands at 9F is probably a stupid idea, I rushed indoors and defrosted my hands with warm water. But all I felt was buzzing, not warm water. Hmm. So today I was melting wax in a soup can in boiling water, and I touched the tin to see how hot it was. It didn't feel hot, so I just grabbed the boiling hot tin of wax and poured it into my mold. The wax dribbled onto my fingers. I didn't even notice it! Later that day it occurred to me that maybe i was having trouble feeling how hot things are, so I experimented. I ran hot water over my fingers, but it didn't feel hot at all. It just feels like my fingers are buzzing or something.  Stranger still, if I IMAGINED that the hot water is cold, it suddenly feels cold! If I imagine it's hot, I get that buzzing sensation. It's probably just a temporary condition, so I was wondering if it's ever happened to any of you folks?

Most efficient way to recover heat from 130 degree F water and transfer this heat to 140 degree F water?

I am making a solar still and I need to recover as much heat as I can from the 130 degree F water (bringing the water temp down to near ambient, 72 degrees F) and then transfer this heat to 140 degree F seawater. I have a limited amount of solar collectors to heat brackish water, send it through an evaporator tower and then a condenser tower to make fresh water. As the fresh water goes through the condenser it gains a great deal of latent heat, thus the 130 degree F water. In order to increase production and regain otherwise lost energy I am trying to recapture a portion of this heat to further warm up the brackish water (currently at 140 degrees after exiting the evaporator tower) before being further heated with the solar collectors. I am operating off grid, so the solution must utilize solar heat or PV panels as the power source.  Does anyone know of a heat pump that operates best in this temp range? What about using TEC (aka TEG, TEP or TEHP) to perform this task? Is there a better or more obvious solution that I am oblivious to? Any advice would be much appreciated.

Ice Rink Leveling?

Looking for anyone's practical experience here. I have made backyard rink last 3-4 yr, now upgrade to Nice Rink liner. Holding water never a problem, many in Northeast last yr had limited time due to warm winter. My rink is triangle shape with legs 20x30. Slope on one side  goes from 1" to 7" or so, average ice thickness is 3-4". Part of rink over brick patio block. Use wood 2x6-2x10 borders. Was thinking of putting hay/straw under liner in the deep sections to reduce volume/depth so I can freeze solid and not have water layer under the ice. Or do you think the trapped air (under liner) will warm and work against this. I would think enough straw would not fully compress and help reduce water level, but then interface between liner and actual ground will have a lot of air space. Got a few months to think on this, my season is late Dec-mid Feb.

How to setup heating element to heat 2 gallons of water?

Hi All, I have a thought on something that I'd love to build, but I'm having some trouble figuring out the best way to do it.  I'm new to everything electricity, so please bare with me on my lack of knowledge on the subject. What I'm building is a coffee maker that you can take with you as you leave the house.  I need to figure out how to create a way to heat up the coffee to roughly 60-80 degrees, then once done you can detach it and take unit with you.   Now, here is the catch.  I don't want to rely on the battery source to heat the water, ideally I'd be able to setup a removable plug that both charges the batteries and heats the element that gets the water up to 60 degrees while plugged in.  Once the water is heated, I'd then like the ability to detach the cord, and you can take the coffee maker with you.  The batteries at this point just need to keep the water warm/hot, not heat it from scratch.   Also, I'd like to figure out how to have a timer on this with an LCD screen.  That way, just like with any coffee maker, you can set the time before you go to sleep and have it ready by the time you go on your commute. Any help on how I should set this up, battery sizes, places that I can find parts I would need would be a gigantic help!  I've been searching the internet for a few hours but cannot find anything. Thanks in advance.

solar powered cooler

Using these ideas as a starting point:http://en.wikipedia.org/wiki/Icy_Ballhttp://en.wikipedia.org/wiki/Einstein_refrigeratorhttp://en.wikipedia.org/wiki/Gas-absorption_refrigerator"Another variant uses air, water, and a salt solution. Warm air is passed through a sprayed solution of salt water. The spray absorbs humidity from the air. The air is then passed through an evaporative cooler. Humidity is removed from the cooled air with another spray of salt solution. The salt solution is regenerated by heating it under low pressure, causing water to evaporate. The water evaporated from the salt solution is recondensed, and rerouted back to the evaporative cooler."Directions on how to make an icy ball.

One of my sisters gerbils died, and my mom didin't notice it until labout a day after, and she had 3. one of them is fine, but the other remaining one has stopped eating and drinking, and its not moving. we put some sugar water into an eye dropper, and put some in its mouth, and now it opened its eyes and started moving around again, but basically all we are doing right now is keeping it warm, giving it sugar water, and isolating it from the other gerbil. Is there anything i can do, like should i put him back in the cage with the other living gerbil, or feed him something else? please help.

Cleaning the oil for a vacuum pump

Was too lazy to do an Instructable about it and think a lot of pics or even videos won't help much if you know what I mean ;) Some of us use rotary vane pumps not for the purpose of evacuating refrigeration systems but for all sorts of fun and experiments. This means quite soon or often we face the problem of the oil taking in a lot of water or even worse particles and solvent fumes. I don't know about you but I was getting sick and tired of replacing the expensive oil every few weeks or sometimes even days if something got too wrong. There are many different blends of compressor oil out there that will work very well in our rotary vane pumps. The main difference is whyt the oil is designed for. Some are perfect for aircon systems, others for the work with solvent fumes and there are even those special oils that bind moisture. Unless you really need to evacuted special gases or solvents basically any low viscosity oil will do us just fine! So instead of paying 20 bucks for special compressor or even vacuum pump oil we can select the cheap everyday oil. Well, not exactly... We also want to be able to recycle our oil to save even more money. That means we don't want an oil that binds to water to keep it out of harms way. We also don't want any oil that has special coating abilities for example these oils claiming to reduce wear and tear on your engine. But any other low viscosity mineral oil or if you prefer synthetic oil will do - just stay away from silicone based oils!! If you have not used your pump for a few days you can often see a slude at the bottom of the viewing glass. If the rest of the oil is clear you can simply drain this worst bit and top up with fresh oil if required. This simple procedure saves you a lot of oil already, at least if your pump has some rest every now and then. Once your oil looks wasted it is time for the recycling and cleaning: Release the oil into a high glass jar or these facy spaghetti glasses. Fill with fresh oil and give it a short run. Release this oil as well and wait for it to properly drain. You now have the inside of your pump nice and clean again, time to fill one last time with fresh oil to keep using the pump. The filthy oil we now have in our jar should be covered with some fine cloth or filter paper and placed somewhere warm. After a week or two the oil, filth and water will have seperated and you pump, drain or siphon out the now clean oil for further use. Don't be too exact here trying to get all the oil out, just remove what you can without risking to suck in the filth from the bottom. Simply leave the rest in the jar and add the next oil change to it for the same recycling process. Solvents.... In some cases we will work with solvents and that means the oil might bind to them. Acetone for example is quite nasty here and can change the oil itself by breaking down certain components. In most cases it means the viscosity will be reduced, which is not really too bad for us. What is bad however is the fact that these solvents often refuse to fully seperate or evaporate. Once the oil looks clean do a smell test and if it smells like solvent then for sure there is solvent in it. Next step to confirm is to do a lube test. Simply place on some smooth metal or glass and smear it with your finger - a drop is enough here. If it feels sticky on the surface, gives you a rubber like feeling when sliding over the surface or is far less "slippery" than the fresh oil you also have a problem. I found that filling this contaminated oil into a proper container and applying a strong vacuum will remove all solvent residue in a very short time. Downside is that the oil in the pump is contaminated again, so it pays off to collect solvent contaminated oil seperately and once you got enough for several refills use the pump to get rid of the solvent. When done do another smear and smell test, if still smelly repeat if no longer smelly but still the same bad feeling on the surface: Discard as the oil might be broken down by the solvent.

FIMO clay, how to re-constitute it ?

I have a lot of FIMO,and I just opened a pack of it. It started to crumble when I tried to shape it on the ends. I tried some water, no help, I tried to warm it a little, no good. Anyone know how to make it supple and workable again. Maybe some type of oil ? Not sure what is in it. No ingredients on the package. Thanks.

How do I keep my chicken's watering system from freezing? Answered

Hi!  I just found this site and can imagine I will be spending a lot of time here!  What brought me here today is a concern from last winter.  I raise chickens and developed a winter watering system that ALMOST works... It involves 80' of PVC piping that is circulated with an aquarium pump and was heated with a bucket heater.  The water is stored in a Coleman Cooler.  The birds access the water using 10 "Chicken Nipples" (http://www.avianaquamiser.com/chickennipple/) and here in lies the problem.  Even though the system flows in cold weather, the small amount of water in the nipple tends to freeze.  I imagine I could heat the system more, but I would rather have the heat directly on the nipples to keep them warm. I could use a light bulb on each but I would rather be more efficient.  I am hoping for a way to heat a bracket or coil around each one and have it turn on periodically as needed (maybe using a timer and a ThermoCube).  All the heat coils I find tend to produce too much heat and I am afraid of melting the plastic around each of the nipples.  I have spent countless hours at Home Depot, Radio Shack and electric supply stores trying to solve this.  Any help is greatly appreciated!   ---Regards Alexander

how to fix holes in a polyethylene/polypropylene solar heat exchanger Answered

This solar heat exchanger is a 5m sq flat sheet consisting of two layers of black polypropylene or polyethlene (not sure which)with rows of fine bore plastic tubes sandwiched between through which water is pumped from the pool at low pressure.The water warms whilst passing through the system, then empties back into the swimming pool, hence, free pool heating. After 2 seasons of use, there are a few leaks at the joints where the fine tubes meet the main inlet tube. I tried to seal them with glass fibre, then cyano-acrylate resin...nothing stcks to this type of plastic. Any ideas for sealing these holes? The plastic is too fine to use a heating method.

Dog Hair Sweaters from Deceased Pets

These folks loved their dogs so much that they made sweaters from their fur after they passed away. This was no easy task as thousands of hairs had to be harvested from brushes and carpets. The result is apparently warm and water-resistant as well as creepy, but with all the cat hair I keep vacuuming up maybe I can get a nice coat from my own home. BBC linkvia Treehugger

How to save an oiled penguin (with knitting!)

Biologist Jeremy Gray explains how penguins are cleaned up after the New Zealand spill: First the penguins must be warm and happy. Most are kept overnight before washing, as it is very stressful and they need to get their strength up. Then the birds are brought into the cleaning room and put on the table. Normally detergent is used to clean wildlife caught in an oil slick.  But the fuel oil that's spilled from the Rena is really thick, so we first rinse the birds with canola oil, sold as cooking oil at the supermarket. This helps soften the fuel oil and get off the really thick stuff. Then the penguin is washed multiple times in 25L basins of warm water - about 41C, to match the bird's body temperature - with 100ml of dishwashing detergent in each basin. We use specially imported dishwashing liquid that's the best for the job. We change water four or five times. One vet holds the bird, while the other scrubs it. We have toothbrushes for the delicate bits. Once the oil is gone, the bird gets a final rinse in warm water only, and is then checked for any missed spots, and the detergent is washed off. It takes about 45 minutes to an hour for each bird to be washed. The birds are then taken to a clean room and put under heat lamps and blowers to dry. The clean room is strictly oil-free - no-one who has touched any oil is even allowed in, in order to prevent recontamination. Once clean and dried, the birds are kept in a water tank until healthy enough to be released. And swimming in clean water lets them preen their feathers back to their natural condition. During my shift - we're only allowed to work eight hours - I helped clean three penguins. And as I was sent home they were gearing up to do the rest. At the time there were six dirty penguins (seven until one died before cleaning), seven clean penguins, one clean seal and two clean shags. More penguins and seals have since arrived. ------------------------------------------------------------------------------------------------------------------------ Now for the knitting... The penguins are in danger from the cold (they're penguins, duh!), but they do need jumpers.  A full-body woolly jumper stops them preening contaminated feathers  and ingesting the toxic oil. Volunteers have been using this pattern from Skeinz.com and knitting jumpers to keep the Little Blue penguins safe. So far, I have only seen photos of the jumper being worn by stuffed toys - if you come across one being used for real, could you let me know?

I need an air moisture meter and possibly a thermometer in one.

Good day,I am trying to find a moisture and temperature meter (possibly in one). It will be a used in a beehive. During the winter the bees cluster together to keep warm. Warm air rises up and gets in contact with the cold ceiling. It cools off and releases moisture. The water then starts dripping down and creates a mess of wet bees and mold. Opening the hive during the winter is not recommended till temperatures get back over 40F. Proper ventilation is possible to achieve through the design of the beehive but i would like to know the level of moisture and temperature if i was to just walk next to the beehive. I have seen a few instructibles about moisture meters but they are geared more toward soil moisture. I need it for the air. The system could be powered by a rechargeable battery and a solar panel - i can take care of that myself. Thanks.

In regards to Slime, what do you think about this idea? Answered

  I have been using Slime for almost 2 years.  This will be my first Arizona summer using the stuff.  Last summer I was in the humid southern states cycling with no problems until I returned to Phoenix.  When my tube could hold no air at all, I replaced it.  Later, I needed the rubber and cut it open to find that the Slime turned to dust.   Now, it is getting warm again and I started to have a slow leak.  I simply added more slime and the problem was solved.  After the fact, I came up with this idea: Since Slime is water soluble and it keeps drying out,  can I just add water to it? It is likely that I will try this out soon enough but I was curious to any input. Thanks

Has anyone ever made a room furnace with a light bulb? I've heard of using light bulbs contained in a metal box. Answered

Any ideas. This principle could work along the same lines as an oil hot water heater pumped through a radiator (you know those 300 lb.+ radiators from older houses), but using the bulb in place of the hot water.. If it was portable, that would be great. I could make a nice cover or wood cabinet around it myself. What would be a good metal to line it with that could magnify the heat of a light bulb. Obviously, this would need to be a safe product. Getting a little warm on the outside is not a problem in our home. I mostly just need some idea as to what metal to use to magnify the heat of the bulb. Thank you in advance for any help or ideas.

Extreme water cooling idea for computer chilling plus dust protection

I started to play around with some compressor cooling devices, otherwise known as fridges, freezers or airconditioners ;) As with everything it started with a lot of reading, some doing, more reading, well you get the point... Anyways, I am now running an old and portable split airconditioner on hydrocarbons instead of the already escaped R22 refrigerant. With all this experimenting I got reminded that my computer does not really like to do hard gaming work on these hot days. There are already a lot of infos out there on how to use water and/or heatpipes to cool your system. One thing that they all have in common is that you need a chiller to cool the water. Now, there are really tons of options here - from using an old bar fridge to hold the water up to big direct chillers that can be used 24/7 and cost a small fortune. Here in Victoria the weather might be more forgiving but up north the humidity will be your main enemy if you want to use any decent cooling system. Imagine 90% humitiy and the water condensing on pipes and coolers inside your computer... Some systems compensate here by using a temp of around 12°C at the lowest to minimise the risk of condensation. But I think we can do better for cheaper if we are willing to get dirty and salvage some scrap. If it also a great way to protect your computer in a dusty and hot workshop enviroment! Let me explain the thought: Considering the costs for a decent air cooled system over the expense for just a basic water cooling kit it might be worth spending the extra money otherwise. What makes a normal and not overclocked computer go too hot assuming it is clean and free from dust? Right - the outside temperature and how hard we actually use it. Normal systems are designed to work at a room temp between 18 and 24°C, we are often lucky to have it under 30 in the summer. Getting a CPU to just under 70° if the outside air is already over 30° is hard if not impossible. But what if the computer would be in one of these fancy server rooms that are kept at 16° throughout the year? Problem solved, just win the lottery to get your server room build. Step back a bit and think again ;) If we make an additional and well insulated enclosure to put the computer in we would only need to worry about making it pretty much air tight and keeping the inside always under 20°C. Now follow me to my imaginary shopping trip... First step is getting a decent sized cooler box - you can build your own of course I would go for these oversizes Esky chests. Next step is a visit to the local hard rubbish collection or scrap yard. We look for a bar fridge or water cooling tower that has a condenser that will fit on the side or back of our cooling box. Prefer something old running on R22 instead of R134a if you can. If the system already has one or two service ports for filling even better, otherwise see you get one from a different fridge or freezer. The fun starts back home where we now make a big mess. The cooling system needs to come apart and if not a tower the fridge around it has to go without damaging pipes or condensers. Perfect would be to have a working system and to keep it in this condition to avoid the illegal escape or refrigerant. It also make it easier than having to refill it again. On the other hand getting a system that is already professionally evacuated as most scrap yards now do anyway can make the modding easier - up to your skill set and options to have the system checked and filled. Once we have a naked cooling system we get the cold side into the cooler box. Either by creating a slot to slide it in or by feeding the hoses through holes if you plan to do your own thing in terms of testing and filling. The compressor part and "hot side" are mounted securely to the outside of the box. If you still have the thermostat working and connected you can now check your homebuild fridge. To get the computer inside you have several option, IMHO the easiest is use one big enough hole to get all cables to the outside. You want this hole to end up as airtight as possible, I found candle wax to be a good sealer if you place some painters tape on the box first. So far this was the easy part, the hard part is now to make sure the humidity inside the box stays as low as possible. When the compressor starts cooling the evaporator will go to very low temperatures, even if you set the thermostat to 10° the cold side will condese or even freeze the moisture in the air. Unlike with direct cooling option inside your computer we now have a "cold trap" outside the coputer that we use to our advantage! Easiest option here is to have a catchment under the cold side to collect the condensing water and to let it discharge through a small tube to the outside. Once the system was operating for a few days there should be no moisture left inside our box unless it is not properly sealed. At this point you could be tempted to just set the thermostat to the coldest possible - I advise against it! Imagine the inside of the box is below freezing - the capacitors won't like it to start with and since we now have all surface subcooled the moisture can condense everywhere not warm enough, including your mainboard. A temp of around 10°C should be more than enough for normal gaming and gives the compressor a chance to turn off every now and then so any ice can drop off and exit. If you like the idea use it and make a featured Instructable out of it, my time is too limited at the moment to get serious with this.

How to Wash a Cat

Let me tell you how I bathe my cat.  This is no fluke. I have even taken a cat to a college class and given him a bath as a demonstration.  If anything would set a cat off, that would. I have even bathed cats that aren't mine. Take a big breath and relax. Your state of mind will influence his. Start with a clean counter next to the kitchen sink. Put towels on it. Don't have them so close to the sink that the cat could grab it.  I generally have the cat facing away from the towels and toward the water faucet.  Don't have him facing you.  He'll try to grab you and climb up your chest.  Get your shampoo opened and handy. Consider which hand will be easier for you to hold the cat and which to wash.  Set up your towels and sinks accordingly. Now, plug the side of the sink you'll be using to bathe the cat. In the other side, start the water. Get it to the temperature you want. Turn the pressure down to a slow flow - on that side. Put your cat into the empty, plugged up side of the sink, facing the wall. I have bathed a cat with and without a towel in the sink. Your choice. Let him watch the water for a few seconds until both of you relax. With your washing hand, cup your hand, fill it with water and "pet" your cat with it. Start on his back, not his head. Do this several times. Slowly move the faucet over to his side of the sink but not ON him. Continue "petting" him with water. If he's relatively calm, increase the water pressure so the sink is slowly filling. Remember, you're washing with one hand and restraining him gently with the other. Put some shampoo on him and water-pet and wash him. Have a little PLASTIC cup handy so you can scoop some of the water from his side of the sink and pour it over him (it has soap in it - might as well use it to the max). Continue washing until you are satisfied that he is clean. GENTLY remove the plug and let the water drain WHILE you are filling that cup with clean water and gently pouring it over him. Scratch and pet him frequently. Talk to him.  Rinse him thoroughly. When you are all done, let him drip a little.  You might want to gently squeeze his legs and tail to 'ring' some of the excess water off of him.  Then put him on the towels and wrap him up gently but quickly. Use old towels. If he has his claws he might snag them a little. Drying is the hardest part because he wants to run away. Dry him as best you can and then release him in a warm room. Don't let him outside until he is dry. I hope this works for you as it has for me.

Will painting a swimmimg pool a dark color promote algae to grow more than a light colored painted pool?

I am picking a new color for my inground swimming pool with filter no heater. Wanted to change to color from a basic light blue to a more modern darker color.  Was told dark colors allow algae to grow more than light colors.  Any truth to that statement?  Also because the pool is not heated which color would help keep the water warm?  I am guessing that a dark bottom pool would be warmer than a light bottom pool.
