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 !

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!

Solar Concentration?

I wonder if anyone has tried this, using either a solar cell, or joule thief powered LED in something like a torch head fitment  with a solar cell capping the end of the torch head such that the maximum amount of vsible light is falling on the solar collector and none is going any where else. Although direct sunlight may be ok to power a PV, because of local weather it could still be described as diffuse and tricky to get a constant intensity of light where it is needed. If it were possible get a gain in efficiency this way it also could mean that you are not constrained by the amount of area you need to lay out panels to catch sunlight, the collectorsand lights could be stacked vertically in enclosed units.Apparently PV'sare most efficient in the visible light spectrum which reduces concerns of radiation (UV or IR) If efficiency and power could be increased in this way small units could be joined in series or in gradually  increasing size to power requirements.

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

I'm using a 5V output from an Arduino through a 15Ohm thermistor - am I doing something wrong? Many thanks for the help!

How to make doppler laser cooling? Answered

I've heard of a form of cooling done by lasers known as "doppler cooling" because it is based on the Doppler effect. I think this is neat and would like to try to make a laser cooling device. I can't seem to figure out how though. I did some google research and all I get is cooling options for lasers rather than cooling options from lasers. What wavelength would you need to do this? Is there a particular way to do this rather than just shining a laser continuously at an object needing cooling. Would this work through a translucent object? I appreciate any help or guidance you could offer.

Can I etch a PCB in the winter...? Answered

I want to etch a PCB, but it is rather cold where I live. I had settled on the HCl/Peroxide mix, but I could use something else if need be. I wouldn't be worried about it, except I get the impression it's a good idea to carry out the reaction outside, where it is cold right now. If working outside in the cold is a no-go, is there any etchant that is "safe" (I understand that safety is relative, I mean along the lines not immediately gassing me) to use indoors with ventilation? If so, how much ventilation is needed? Are we talking an open window, or an industrial fume extractor? Also, I wasn't sure which category and channel would be the best, so if a mod or somebody sees this and has a better classification, go ahead and change it. Sorry for making this such a long question; I'd just like to be able to use my circuit board before I die ;). Thanks, dedgerton

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?

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.
