Acid batteries are sooooooo 90's.

What you want is a Lithium Iron of Nickel Metal Hydride. More power, less weight and far less prone to the dreaded 'memory effect' than othe types.

There are loads of ways to make your own battery. it depends on what kind of power you need. You can even make a battery using your own bodily fluids. And I don't mean the yucky ones.

"New fuel cell opens way for artificial hearts

May 13 2005 at 09:10AM

Tokyo - A Japanese research team has developed a fuel cell that runs on blood without using toxic substances, opening the way for use in artificial hearts and other organs.

The biological fuel cell uses glucose, a sugar in blood, with a non-toxic substance used to draw electrons from glucose, said the team led by Matsuhiko Nishizawa, bio-engineering professor at the graduate school of state-run Tohoku University.

"Since the electron mediator is based on Vitamin K3, which exists in human bodies, it excels in safety and could in the future generate power from blood as an implant-type fuel cell," the group said in a statement.

Most other bio-fuel cells under study use a metal complex, spawning concern about harm if used for implants.

The newly developed cell in the size of a tiny coin is able to generate 0,2 milliwatts of electricity, enough to power a device that measures blood sugar level and transmits data elsewhere, the group said. -

So I made my first tyre warmer the other day at my uncle's house (he's a sparky )
Looked real good ...till it melted
....the "heat-resistant" material, wasn't so heat resistant after all

But at least I know the electrics work Now I maybe just need to put a higher resistor into it....and find some better material....I found some "wadding" that might be a goer....

Anyone know where I might be able to get hold of a second hand fire blanket?

Yup - go to any electrical good repair place. They'll have heaps opf them about now (they all come in for testing at the start of winter - and any with broken wiring get biffed).

... no offence Biffy...

A quick ring around ought to do it, and if they worryt about unsafe goods being handed over, get them to cut the plug/lead off at the blanket.

I'm trying to invent something that uses solar panels as well.
A couple of questions peoples might help me with.

1. How do you measure the 'power' (energy), of the available light hitting the panel?
2. where can I get transparent panels?

Thanks.
Racey.

Actually MDU - I only realised last week that the term Biff'd implies something is broken. I therefore demand that, from this point forward, the entire nation refrains from using this word, unless you're referring to me of course, of which there is just the one, unique, sexy, talented, egotestical, studmuffin.

I am not broken, all my bits work fine thanks, and I have the photos to prove it.

ok - now I think you're mad... scary, remarkably funny... but mad too.

I can see we'll also need to discuss your condition over a few fine bottles of vino - for medicinal reasons of course
