I agree cutting under oil is the best thing, if there is enough heeat to ignite the oil then the metal is sure to burning already, lol.

I've gatta get me some of this stuff, never got round to it tho,

lol. all this bring back memories when i do this stuff, I went home with a home made rocket smoke bombs, etc the whole kit. lol. (as I didnt have a garden at uni)

told my mum what i was doing and she came out and watched, lol.

Wha'a'mum.

Then I found out its not legal, I told my mum and she say I know, lol.

funny, the rocket was great.

Mg ribbons ok(ish) it only has a 40% 1`st time success rate on some thermits though

 

Sparklers are well up in the high 90s

lol. so you need to put in 3 fuses, giving 120% chance,

lol.

nice

lol. thats cheaper than bying it un the UK, well now the $ is low, muhahaha

Also I was trying something last night, when I was making a new cell the only thing I could find to make the anode from was a tin can (beans type) I washed it and cut it up, but it works as well as plastic would.

the plate size was around 5x5cm, when I added my carbon rod it almost 4x the current output. I really dont get wy a tin can is so bad, it conduct fine with connected with a real cell, even doing a ohm test shows it to be fine.

any ideas?

why nopt just buy a roll of MG ribon? its £9, thats better then looking high and low for other things,

If need be buy some I'll go halfs on a roll.

lol. for my new one I'm using an old underarm spray tin, not too bad for thinkness, (better than the foil, which has a coating on anyway)

But Carbon is so good for conducting, thye should make cable from this stuff, lol.

I've got some activated carbon which I'm going to put together to make a carbon plate.

I think If try hard I could get a whole month for the 250G weight.

Yeah I need some help on this. I know alu oxide has 3O atoms, so I need 3x mols of water to alu, but my mols working is poor, what would that be in a ratio?

say 1g alu to 5g water?

I've go some alu rods from my brake level (my bike) from when I crashed, thats made of alu just needs the coating taking off, maybe we should drop the weight?

lol.

nah went out around 37hr or so, not bad tho for little foil, on which I can make the design much better, its great how mcuh you can learn from a proto type.

I've also learned that stainless steel is a crap conductor.

YT you used brass foil, is brass an copper zinc alloy? if so doesnt zinc react with sodium hydroxide?

Yeah I'm getting 1.8 volts across 2 cells.

I'm not too fust about the current, just enough to light the LED, its still going, lol. works great for a little bit of foil,

Its still going, dim but still lit, thats almost 36 from foil. wow, lol.

I take it better bacause it doesnt let the oxide stick to the surface?

I started a battery (just testing) last night using aluminium and K-OH, almost the same as YT, (I didnt know YT did his in that way til I read it, lol).

using take away trays about 3cm by 10, (2 of them) I started it 5ish this morning and so far it still going.

next test will use a better anode (the none alu probe) as at the moment I'm using only carbon rodes, which have a small surface area etc.

so I';; increase my surface area of the anode and then drop the amount of K-OH to slow it down as with the bigger anode it picks up more of the electrons etc.

I just did a quick test using a copper plate extra on the anode and it worked great, so I've been funny hot all this time, tut tut at me, lol.

works great tho, and is you want you can collect the hydrogen and make a fuel cell (palladium etc as the cat, costly tho) and them old drink cans are now making you a cuppa, looool.

o well, I've never come across that before.

YT how come you didnt use aluminium? or is that not as good.

anyone hear "red dwarf" ? lol. a bubble of time 3million years,

@YT I cant remeber the name but isnt there an acid which doesnt burn your skin or anything like that but will attack your bones, ouch.

yeah, but I'm from Doncaster in the north, just down here for uni, been here 2 years will be here for another 2years, shame as this place needs some trees, how i miss the north.

yeah but there words are totally different. o well good thinking none the less.

Seen it b4, never can get anything good about that sirt of thing, lol
