Hi there, I need a water filter for my well, which i can hook up before the water riches the pressure tank. I got a lot sediment in the well. I was thinking of a filter like from a fish tank. My Idea is , i fill it with gravel from big to fein (Sand) gravel in at least a 6 inch pipe and about 4 feet long. The pump company ( Flotec) told me that i need a pipe with min. 100psi rating. I want use a clear pipe so i can see when i have to change (clean) the gravel.It should also be mounted in the basement ( freeze protection). I found on the i-net a clear pipe with treats on the top and bottom, but than it's not rated any more for 100 psi. so what can i do. Any clue?

This is a clam shell bucket, from an old toy crane. I am taking this to a machine shop, welder, had having them make it 18 inches wide. It would be used only with rope, no block and tackle. Problem: As best I can surmise, about 1-10 percent of hand dug, round water wells used by around 4 billion people on the planet are full of silt, dirty, and old plastic jugs used to pull the water up from well. As the silt rises in the well, the wells slowly become too dirty, or the locals need to pull the water out in buckets, then allow the silt water to settle. It is way to expensive for people who earn 10 USD per day to pay people with pumps to drain the wells. I want to create a 1-2 man powered clamshell bucket system to clean these wells. What is the best way to make a method to clean a dug well? How much would the steel, rebar cost? Labor is 10 dollars per day in central American, South America, Africa etc. Thanks for help, I will take the finished bucket to Lome, Togo West Africa to test, and modify, iterate.

I was thinking about another fun project that draws water out of the air with just the sun's energy. I noticed the empty open vinegar bottle I washed and set to dry on my window sill accumulate more moisture every day. It was pooling water in the bottom after a week. The bottle shape is like a ball with a long spout. I read a little about air wells on the web, but they are very large structures. It would be fun to build a small one that would make a few glasses of water a day. Comments?Here's one link Air Wells & Dew Ponds

So I am building a small cabin in the woods near my house, It is on a very small ridge to the gully below. In the gully I dug a test hole for my well and had a hole at under two feet that fills up immediately when you scoop it out. Should I stay in this spot or will the water be bad?? I doubt if I can go very deep because the hole is now filled with water and there is about two feet of rock just under the surface I know because I dug a hole for something else nearby. Drilling of any sort is not an option as the rocks are to large. Should I just move nearby and try to go deep in that spot. I might get four feet in another spot. Thanks!!

Just as it got warm here, our dual fan, window fan gave up the ghost.....but I wasn't about to just throw it out without a fight..... First step, most likely suspect, since there was no strain on the cord, was the switch, an old OLD 4 position mechanical clunker that sparked visibly in the dark under the Bakelite case. That seemed ok (it was screwed together so disassembly was a snap). Testing continuity gave mixed results. So, I found the place where I has spliced a longer cord into the short wire to the switch and viola'! After only 45 minutes of getting absolutely filthy with dust, I found the broken wire. This time, instead of just soldering and taping, I put some heat shrink tube in line before soldering them back together. Now I have my fan back......ok, so I guess I am not completely worthless yet :-)

INTRODUCTION: How can we best apply basic technology to help the underprivileged and/or disaster-hit countries like Haiti? Daily hygiene and nourishment are among the top needs for disaster ridden regions! Simply put, no water means no hygiene. The Romans understood that over two millennia ago and created their complexly beautiful aqueduct networks for handling both fresh and wastewater! Other ingenious water systems like “air wells” have been found in the city of Theodosia (cf: discovered in 1900 by Zibold, see Zibold’s Collectors/Dehumidifiers) dating back to Greco-Roman times during the Byzantine Empire. These were strictly passive systems that naturally dehumidified air, collecting its potable water in underground basins. All air, even in relatively dry desert regions, will precipitate or release its natural water content (initially in the form of vapor) through condensation when it hits its dew-point temperature and below. That means you “chill” it to an appropriate level that is anywhere from 5F to 50F below its current air temperature, depending upon how much water content (relative humidity) it has locally absorbed. The condensation of the water vapor releases its internal latent heat (reheating the cooled air) which must be constantly dissipated (absorbed by something) in order for water formation to steadily continue. So how do we dissipate this resultant vapor-heat and chill our air without any infrastructure or electricity, in an underprivileged or disaster-ridden region? We simply bury a long cast-iron or any metallic drain-pipe sufficiently underground where the temperature of the earth is naturally held to a constant at around 45F to 55F. That’s our “free” chiller gift from nature. One end of the pipe, Figure-1, sticks out of the ground to suck-in local outside hot air, and the other end dumps cooled dry air and water into an underground cistern where it gets collected and is piped to the surface to both exhaust the cooled dry air and connect to a water pump. We need a hand operated water pump to lift up the water above ground, and we need an electric fan to constantly pump air through the ground-chilled piping system. We can even force the cooled piped air to exhaust into a tent-like structure where it provides air conditioning as an added bonus, but this adds the penalty of both power and the increased fan size necessary to drive our required airflow further into an enclosure! While this concept is not “passive” (requiring electricity to work) like those clever Byzantine air-wells, it will produce much more potable water and within a smaller volume than those elegantly passive historic devices. The electricity for our fan power requirements can be produced by any one of four ways using either “active” or “passive” techniques: 1) An active playground or bike-pedaling-person or oxen-driven mechanism-generator, 2) A passive windmill generator, 3) A passive solar energy collection system that directly generates electricity, or 4) A passive thermo-electric system that directly generates electricity using the Peltier effect, operating solely on temperature differences between the cell’s top and bottom surface (we jury-rig the cool pipe and hot ambient air to contact separate sides of the cell). Depending upon how much water is needed, the required air volume plus pipe length and diameter, together with the fan will be sized accordingly. We can also configure groups of parallel fan-driven air pipes that are radially fed into the cistern. The sizing of this underground network depends upon the ambient air’s local average temperature and relative humidity (how much water gets absorbed into the air) plus buried pipe depth and effective underground temperatures achieved. The basic concept is one where we “wring” water from air at some given humidity content. The higher its relative humidity the more water is recovered from the air. The air-wringing process simply chills the air as it scrubs along the cooled internal pipe surface until it starts to rain inside the pipe from condensation onto its surface. The condensation is like the dew that forms on car windows, grass or any cooled surface in the early morning, before the sun comes out and evaporates the dew back into the heating air. A further bonus is that our dew-formed water is naturally distilled and very clean. It is potable water ready to drink without the need for additional sterilizing agents. Of course, we must make sure that the interior piping and cistern network is biologically cleansed before burying it underground. The hand pump with its 10 to 15 foot extended piping to reach the underground cistern must also be cleansed. The beauty of this constantly replenishable water supply is its convenient underground installation anywhere! After the in-ground installation, we have a virtual, partially passive, no moving parts, non-breakdown system containing above ground total access to all moving parts that could breakdown, namely the water pump and electric fan. Also, it is easily maintained, with few moving parts (water hand-pump and electric fan) and basically lacking any technical complexity which makes it ideal for technologically backward regions. The example below uses a relatively small industrial fan moving air at 1500 CFM (Cubic Feet per Minute) with a DC motor rated at 1kW. This fan together with our underground piping system will conservatively generate 12 GPH (Gallons Per Hour) of potable drinking water without need for any purification chemistry. Based on an average electrical cost of 14-cents per kWh (kilo-Watt hour), the typical commercial distillation of one gallon of drinking water costs roughly 35-cents as compared to our cost of only 1.2-cents. Furthermore, if we decide to go green and use solar energy for generating our water, it would effectively cost us nothing beyond the initial installation! USING A PSYCHROMETRIC CHART TO SIZE OUR WATER SUPPLY: The following gets a little technical and is only provided for those die-hards who are truly interested in how the science works. Those non-technically schooled may skip this part and not miss the basic concept. Figure-2 shows a Psychrometric Chart for air. This chart summarizes some of the basic thermodynamic properties of air throughout its typical range of operating temperature. The chart uses six basic air properties that defines the physical chemistry of water evaporation into air: (1) the enthalpy or total energy contained within a unit of air which is a combination of its internal and external energy, expressed as the amount of BTU-energy per unit mass of reference dry-air, (2) the specific volume or the ratio of a unit volume of local air to its mass of reference dry-air, (3) the humidity ratio or the amount (mass) of moisture in a local unit of air divided by its reference mass of dry-air, (4) the percent relative humidity per unit of local air, or the mass ratio (expressed in percentage form) of the partial pressure of water vapor in the air-water mixture to the saturated vapor pressure of water at those conditions (the relative humidity depends not only on air temperature but also on the pressure of the system of interest), (5) the dry-bulb temperature or the locally measured air temperature, and (6) the wet-bulb temperature or saturation temperature which is the local air temperature experienced during constant water evaporation (a wet-bulb thermometer is typically used: a thermometer that measures resultant temperature while wrapped in a water wet-gauze and spun to generate local air movement and max-evaporation) 1.0 The Process and A Sample Calculation Our Psychrometric Chart uses six thermodynamic properties that help to determine the amount of water available for extraction from the local ambient air as a function of its temperature, pressure and relative humidity. Let’s assume the following local ambient conditions for the region we plan to construct our water system at: (1) Typical daily air temperature Td = 106F and one atmosphere pressure assumed at sea-level, (2) Relative Humidity, RH = 55%, and (3) Typical underground temperature down at six feet is measured at Tu=55F (at 12ft. it drops to ~45F). This yields the following calculated results for obtaining a steady-state supply (changes at night) of water to fill the cistern: 1) In our example, the “local” air (dry-bulb) temperature is Td=106F, at a relative humidity of RH= 55%. Fig-2 indicates that the resultant Humidity Ratio is HR= 0.0253 Lbs-water/Lb-Dry-Air (intersection of Td=106F line and RH=55% line, then horizontal to HR value). We then determine the “gulp” of air volume containing the HR Lbs-water which corresponds to the point of intersection of Td and RH. Interpolating on specific volume “mv” yields mv=14.7 ft3/Lb-Dry-Air (this value sets the optimum unit airflow for our given ambient conditions, and creates a ballpark pipe length to diameter ratio needed later). It represents the basic unit of air volume that will enter our underground pipe per given time, and ultimately defines the size of our fan and piping network. For increased water creation, multiples of this unit volume will scale up the additional amounts of water that can be collected. 2) As the inlet air cools down to a temperature of Tu=55F, from contact with the relatively cold underground pipe, we follow the constant enthalpy line (red upward left-diagonal) from the intersection of Td and RH to its saturated air temperature condition of Ts= ~88F, which is its dew-point temperature where the corresponding local RH=100%. At this temperature or under, the air precipitates and releases its moisture content, resulting in water condensation onto the pipe walls. Since our air will chill to a final pipe temperature of Tu=~55F, we follow the RH=100% saturated curve (green) down to yield an HR=~0.009 Lbs-water/Lb-Dry-Air. This is how much water is left in the air when it gets to 55F. Therefore for every pound of local outside air that enters the pipe, mw=0.0253 – 0.009 = 0.0163 pounds of absolute pure, distilled potable water precipitates onto the inside pipe wall (per pound of dry air that is cooled and dehydrated) to gravity-flow out the pipe exit and into the cistern. 3) We now convert pounds of air per unit time into a unitized volumetric airflow that yields gallons of hygienically pure potable water production per unit time. For every Va=100 ft3 of local volumetric air movement per minute (CFM) through the pipe, which translates into ma=Va/mv= 100/14.7 = 6.8 lbs. of dry air per minute or 6.8 * 60 = 408 lbs. per hour (PPH), to yield a water-flow of mwf=ma * mw = 408 * 0.0163 = 6.65 PPH or 6.65/8.345 = 0.8 GPH of water. An industrial fan rated at 1kW DC will typically move 1500 CFM at a pressure of 8-iwc, to continuously produce 15 * 0.8 = 12 GPH of pristine potable water. 4) Not shown here are the design details of sizing our pipe, fan and solar collection system for electric power requirements using heat transfer principles coupled with a thermodynamic heat balance, and aerodynamic fan performance assessment. These details help to size the electric power generation requirements plus margin used to properly size a solar collector containing further margins for overcast days. The engineering involved here is straight forward but beyond the scope of the current project.

I mounted a rototiller engine (Tecumseh TC300 or TC200 I think) on a bicycle after un-siezing every moving part on it, cleaning the carb etc. It seems to run well and starts very easy. But for some reason it won't make the bike move. When it's at full throttle the engine doesn't bog down or anything but smoke was coming from the centrifugal clutch and it didn't move the bike. The wheel on the bike spins if lifted off the ground but stops under any resistance. I don't think the gear ratio is to wide but that might be part of the problem. I think the clutch is not gripping well, but it looks exactly like the new one that I looked at. There is no friction pad on the shoe, just steel on steel. Should I try cutting a cross-hatch into the shoes and drum of the clutch or is there a better way? Mabey something I'm overlooking? _______________________________________________________________________________________________________________ UPDATE: The problem was the gear ratio. I have made it much narrower and the bike works now, but it has little torque espciaaly below about 5 mph. So I will make the gear ratio even narrower.

What I would like to get my hands on are small heating elements capable of temps between 80-400 degrees F that are as accurate as possible, preferably within two degrees. I have tried researching this online, but after browsing for an hour I was unable to come up with anything that would suit my needs.

From what I understand those 'super chips' people buy to override the computer and add power typically change the air/fuel ratio.

My idea is to create a small housing around the airbox thermostat and digitally manipulate the termp in order to manipulate the A/F ratio.

Hello, I've been thinking lately about moving out to the desert lately and living off the grid with a well, but I'm not sure my base idea for pulling up water from a well will actually work. My idea is to have a line running up from the well (ending in a one way valve) to the bottom of essentially a steel water trough with a glass lip on top making it airtight. A pvc would run from a hole in the top to a water storage tank to move water vapors up there and condense them. My hoped mechanism of action would be as the air heats up in the trough due to the sunlight it would force the water up from the well little by little and evaporate it. My question is, will this actually pull up water from the well or would I have to buy a solar pump? I don't need lots of water fast or high pressure, the water storage will gravity feeds and collect throughout each day. My other idea which I'm pretty sure will work is having the showers, sinks, and washer (using a compost toilet) feed a one way line out to the hotbox too. If as little as 50% of the water makes it back into the lines that way then I will have cut my water usage in half. What does everybody think?

I get up to -5db (thats what the volume units are on this unit) and it still isn't as loud as I KNOW they go.Here's my idea, the amp has a B channel specifically for a second set of "front" speakers, If I were to connect the left and right channel of each speaker channel together (the negative and positive leads together, not all together, but seperatly together). Would this get me 220 watts per channel? Or just make some drastically horrible sound?

On my way to work today I came off my bike at somewhere around 20-25mph, on a long sweeping corner I was turning with a steady lean and just lost all grip, both tyres slid, my left elbow hit the ground, shredded most of the skin on it and I actually brunt a hole in the jumper I was wearing with friction, I flipped over and smashed my wrist in to the ground so hard that that doctor wasn't sure if it was a sprain or break due to swelling, at some point my left hip hit the tarmac and they Xrayed that aswell in case I had chipped it, there's a nice swelling forming there... I also scuppered both my knees, the bad one is now just popping out from under me at any oppurtunity while the other can barely be moved. I've also just noticed that theres a bit of wood or stick stuff in my arm. This means that I can't go cycling for two weeks by docs. rules, can't play guitar hero, can't lift anything, might not even be able to drive, which would suck nuts as I just started formal lessons, finally afford them and I'm put outta work for a week and can't use my time to do the stuff I want/need to do. On the upside I can get to the hardware store and get my pulse jet parts and be doing something with my time, but I wont be able to build both because I've to save extra wages for next month as I wont get my days off back. The bike stood up to the crash much better than me, scraped paint on handlebar bell and I somehow knocked the reflectors of one of the pedals, I'm guessing thats the big gash on my shin explained... It's wierd I've been hit by trucks and got up straightened the handlebars, cycled off happy enough, I had the same type of crash except the front wheel fell down a curb I clipped a car and hit a wall with enough force to damage it and was fine apart from minor bruises, this simple crash screwed me completely, I fell perfectly and rolled well after flipping and smashing my right wrist, the bike somehow got a good distance away from the crash, as did I... Also three instructables I was planning will have to wait for at least a week, depending on what tools I can manage by then, it's a shame I just made three great projects and I have to wait until I'm better to finish them and publish... it also took me about 25minutes to write this...

TL;DR version at the bottom, below the line Oh you know, just one of those " I like x " situations, except with a twist. So yeah, I like this girl, we talk for short the small short talk (lasts for about 0.8 seconds). She might know that I have a crush on her (since about 30% of the class knows, of which 80% are friends with this person), but I'm uncertain. Either way, I'm not shy about that. The problem lies in the fact that the 24% of the class that's friends with her knows. Normally, they're always with / around her, which makes talking with her (in the first place) already challenging. Imagine maybe 4 people interrupting your conversation only 2 seconds in. It's like trying to play a video game with the worst ping ever; your talk getting interrupted and all. I would just like to have a chat with her that lasts over 15 seconds, at least, that doesn't involve official business (all talks with her so far involved school projects and such). To my assessment, she's astoundingly similar yet the opposite of me... She's simple, yet highly organized (that's me). She doesn't wanna stand out (like me). Generally silent, shy and reserved (somewhat like me, most of the time anyways). Now here's the part I would like to relate to, but I don't know how: music. She plays the piano, and I play the violin. Now, these are performing arts; you perform these in front of people. We don't play the same instruments, therefore we can't talk about it. Composing a piece? Not a chance. That's my work mode wherein I become secluded from the world (bad impression). Intention: I would just like to make friends, thank you very much (did it last year, too, though without the complications) Age: 13 turning 14 (me) and she's 13 More details: -Freshmen -I can control myself, thank you Additionally: I don't know if she likes me or not. I just need to become friends with her to clear some things up and... make more friends? I'm not bringing my hopes up, though. I have an opportunity to start off our friendship (which is due in less than a week), since we have this Christmas party going and we're supposed to have a gift exchange with a "randomly chosen" person which is done by just pulling out folded pieces of paper and.. yeah, there's the name. The wishlist is simple, yet a tad pricey (just roughly $10, but compared to my allowance). This is getting too long Questions: -How do I make friends now? -How do I sustain this? I'm not good at making friends. I either attract them to me or it was a need that developed. __________________________________________________________________________________________________________ TL;DR version: I like a girl and I want to make friends with her, but then I can't talk with her because of massive external social pressure from her ever-present friends that know I have a crush on her. How can I approach her and sustain our friendship? Thank you.
