A hotbed of cold fusion

I'm a sucker for fringe science. What can I say?From the BBC News Service:The long-standing debate about cold fusion is receiving new impetus at the American Chemical Society's national meeting in the US this week.Cold fusion, first announced 20 years ago on Monday, was claimed to be a boundless source of clean energy by Martin Fleischmann and Stanley Pons.Attempts to replicate their experiments failed, but a number of researchers insist that cold fusion is possible.The meeting will see several approaches that claim to produce fusion power.See the full BBC article here

Cold fusion experiment

I have reproduced some experiments on Cold Fusion. not as a source of energy but how to blend a wire of iron from 2mm with less than 2 ampere or obtain gas fuel from the water and graphite (coh4) without using dozens of amps.Do you think may be is interesting to do an instructabels to the matter? are not my nventions!I have same video of this experiment on my youtube channe http://www.youtube.com/user/alessiof76 Almost all in Italian language.. but with a little explanation also in EnglishThe power supply that i use and the experiments can be dangerous.. I would not like someone to dye !

cold explosions

I know that by adding ammonium nitrate and water the compound gets cold. so my question is by using ammonium nitrate and other then water can I use to make extream pressure build up in a short time while still being cold. this question is not for any explosive device to cause harm to anyone or thing. just wondering if a cold explosive could be possiable. thank you

How do you define "cold"?

Seeing as how we all live in different parts of the world, I got to wondering how y'all define "cold" and "hot", and when it is. Down here in mid-Georgia, hot is around 85-90 degrees and up, starting in late March to early April, and lasting until mid October. Cold starts at around 50-45 degrees (though I can go with shorts and a T-shirt in 20s) and those temperatures start about mid-November until early February. Anytime in-between is the perfect mellow temperatures. Just curious. Thanks!

Cold Sores

So, this topic is directed toward all of y'all out there that have cold sores, also known as Type 1 Herpes. I'm fairly sure I just got one (my second), as I tend to get one every year, and I know the symptoms. I've read through various medical websites, and have discovered many homeopathic ways to treat the sores. Mine is still in the "tingling" stage, but it won't for long. One of the methods I have tried so far is to take an ice cube and hold it with moderate pressure to the sore, until the cube melts. Afterwards, dry your skin off and dab some alcohol on the sore to disinfect, and repeat. I believe it said that this will slow the spread of the virus. Is there any truth to that? I'll be going on a 2-day field trip on Thursday, and don't want to have to constantly worry about not touching my mouth. Plus, those of you that have gotten cold sores know that they look disgusting and hurt! Basically, I'm looking for any homeopathic (like, not including medicines) remedies for cold sores. Thanks y'all!

How to mount Peltier elements?

A peltier is a element that gets very hot on one side, and very cold on the other side. Cold enough (with enough power) to make frost all over it. So. I got one, I want to make nice cold cold air. I read wiki, if you don't heat sink it, it will self destroy. If I heatsink the cold side, then a fan on the heat sink to blow the cold freeze air, will it be fine? Or must I cool the hot side too? Peltiers are cool :D

Cold Cathode Tube Voltage and Speaker Questions

My brother has some cold cathode tubes, some about 6" long, some about 12" or more. I was thinking of hooking them up to my bike, as shown in one of the great Instructables here, but I wasn't sure of the voltage. I don't want to over-power the tube, and bust it. Plus, the two wires coming out of it are in this black connector, so I don't know which is positive or negative. The tubes put out blue light, if that makes any difference.I have an old sports radio, which works pretty good and could be turned up really loud. I desoldered the speaker, and hooked it up to a pair of wires coming from a head phone jack. I plugged it into my iPod, expecting loudness, but no - I had to hold it up to my ear, on full volume, to hear it. Is it because the iPod isn't outputting as much voltage or current to the speaker as my radio was? The radio used 3 AA. I really wanted a portable speaker that actually put out big sound, so I didn't have to have those buds stuck in my ear.Thanks y'all!

Temperature sensor with cool thermistor

Hi, I am trying to make a temperature sensor using a thermistor. I've made a basic circuit using an Arduino and some tutorials from this site and couple others, which works well but the thermistor heats up way too much - perhaps to about 50 or 60 degrees - but it needs to stay around room temperature for my application. I'm using a 5V output from an Arduino through a 15Ohm thermistor - am I doing something wrong? Many thanks for the help! The one I've made is almost identical to the one in this tutorial: http://www.circuitbasics.com/arduino-thermistor-temperature-sensor-tutorial/ except a different thermistor

Powering Peltier Plates

Hey guys,So, I just got a Peltier plate, a device that gets very hot on one side while very cold on the other. It requires 90 watts of power. I was just curious what would happen if you powered it by USB or 9v battery. I found this tutorial which uses USB, however, I doubt it gets to its maximum coolness potential. Also, if I used a 9v, would that drain the battery in a matter of minutes, or even damage the plate?Thank you.

Cold Cathode lamp with SOLAR power / battery?

I have an cold cathode lamp from a scanner. I want to install it behind a piece of artwork i made to sort-of backlight the image. it can be very dim... i don't need to get full brightness out of it. My question is.. do you think this is possible with a solar panel and rechargeable pack of some sort to dimly light this thing???? I really want to use solar on this, due to the nature of the piece itself. Any ideas on watts or volts or any other input??? On the power input for the scanner itself it reads 16VDC 0.9~1.0A... if that helps. any help or suggestions are welcome!!! thanks !

Help wanted in the UK: Dealing with SNOW

Hello there all, As you might be aware, us here in the UK are having a fair amount of snow, which as you might also be aware, causes our country to slowly collapse... Since those of you who live in Canada and northern states of the USA are quite a bit more used to the snow, I wondered if the collective genius of Instructables could give us some tips on dealing with snow... Things which'd be interesting to know about: -Footwear -Driving -Clothing -Shovelling I think you get the picture. Cheers!

Keeping my equipment warm

Recently i went to take pictures in the middle of the night at Subfreezing temperatures and the front of my lens formed ice. so i need to keep the lens warm, there are many solutions but the one i thought would be fun to use is the use of a heating element. I found resistance heating wire, i would like to make an object that could fit around my lens and keep it warm. to prevent overheating i will use a microcontroller with temperature sensors to cut of the supply of electricity at a certain temperature. i just want to keep the lens at more than 5 degrees centigrade. I think my 12v lead acid battery will be enough for this kind of project. My question is how to do it, how much heating wire should i use? how much heat will it make? what wire should i use? Will it work? Any other ideas are welcome.

Covering up computer vents?

My computer has these vents on the case that are blowing out cold air while my expansion slot vent is blowing out VERY hot air. I was thinking I could cover up the vents that are blowing out the cold air which is very cold so I could make the inside of my comp cold so my video card doesn't get as hot. Is this a good idea?

We bought a shade to set up but I was thinking the styrofoam would just be a little bit more of a help! What do you think? All ideas and advice would be greatly appreciated!

Laptop LCD Cold Cathode re-use

So recently, an old laptop of mine died. It was an old dinosaur of a laptop, slowly running down the remaining years of its life. Then it died. So sad. To honor its death I dismantled it. I got an interesting motherboard, some decent speakers, a 5gb harddrive along with a floppy and disk drive. What really interested me the most though is the LCD screen. At first I hoped that I could re-used the screen as a tertiary screen for my desktop, but later I realized the near-impossibility of this task and gave it up. Instead I chose to take the screen apart for its cold cathode lamp. It's almost 12 inches in length, and very thin. Before the motherboard died, the LCD back light was still working. So I wanted to take it out, along with its inverter, to attempt to re-use it. Soon after doing this I saw a problem in my plans: the input of the inverter is a whopping nine wires. This is a bit more than I'm used to dealing with for power supplies. I was wondering if you guys knew any way that I could go around this? At request I can most more pictures and model number of the inverter in case you can't read it in the photo. tl;dr - Cold cathode inverter in picture. output is two wires, input 9 wires. How do I use this

Energy underneath your house?

Hi all! I've being thinking on how to get off grid for a while now, in the first stage to use solar power to get the energy bills go down and in second place to get my stamp on earths energy consumption, using my house in a greener way. So solar energy and wind energy are on my mind, but recently i started to think about more possibilities. Like using my crawlspace to work for me. Maybe its posible to make a wind turbine underneath the house, or use the constant temperature to cool my house during summer. I've seen plans on the internet ( and cant find them anymore... ) about using a sort off vacuum chamber that has a constand wind flow comming in, trough a system of pipes that drive a wind turbine inside. The idea is that, because of the vacuum effect, you need only a small gust of wind to power the turbine. Where i live theres always wind, sometime a little, sometimes waaay to much. The crawlspace i have isnt that high, about 50CM in hight, and during the Fall and Winter months theres a high level of water, about 25CM. Durring summer its mostly muddy sand, so there's stil a lot off cool water trapt in there. So about the idea on cooling my house, how about a water cooling system that runs trough the house? How would you guys make such systems, have you already tryed this out, and are there some enthousiastic folks out there willing to go all the way and show these idea's are doable, so everyone can make it??? Hope to hear from you soon ;-) Greets, Arie

Cold Weather Bike Wind Deflector

So I've taken an indirect pledge not to commute to school VIA car - by not buying a parking decal... Since school started, I've commuted, by bike, nearly 400 miles. But now it's starting to get cooler. I really don't like riding in cold weather. I typically wake up cold, get ready (still feeling cold) and getting on a bike when it's cold out is pretty uncomfortable.... So, for my next ugly bike abomination accessory.... My first wind deflector fairing prototype. I made a model in SketchUp (this was my "learn to use SketchUp" project), then from that make a development drawing (3D shape to 2D cutout) and cut that out of some scrap cardboard (I've got quite a bit that I rescued). Yes, there are flaws in this design - it's my first attempt :p As of now, I need to figure out how to mount this thing. I currently have some surplus 1/4" threaded rod at my disposal, I'm going to grab some and see where it takes me :p Comments?

Peltier dehumidifier

I hope someone with a technical background can help me with this... I am trying to make an DIY dehumidifier. The goal is to lower the humidity of my room during the summer months (humidity is around 70% at 25C) to less than 50, preferrable 30%. I have the following setup in mind: To achieve condensation I want to use a peltier that will lower the temperature of an radiator. The condensed water will be gathered in a (plastic) box. This water will then be used to cool the hot side of the peltier, using a water block and a waterpump that was left over after using watercooling on my PC. The image depicts an simple graphic of the setup. However, I have the following questions to be answered: - How cold (relative to the ambient temperature) would the cold-side radiator have to be to get optimal condensation - How much watts of cooling power would the peltier need in order to achieve the needed temperature difference - If i lower the cold side temperature with 20C, how much heat would be generated on the hot side? (my gues: 20C, but im no genius ;) ) Thanks in advance!
