don't repeat that i'm stupid cuz i already jumped to that conclusion.
Me and Chris (FugitiveEagle) have once again tried another stupid and dangerous experiment, this time with hydrogen.. lol.. Anyway we separated hydrogen and oxigen from a 2l bottle of water for a few mins, the cap wasn't on, we only had about 10v at maybe 1 or a little under 1amp. So it didn't do much. And it didn't burn or anything.
How dangerous can hydrogen be, from what i know it's more powerfull then fuel(car gas), is it true? And how dangerous would it be to try to make that lawnmower we repaired to work on hydrogen or at leats give it a bit in the fuel mixture for a little boost and a small gas consumption lowered...
Sorry for any spelling and punctuation mistakes, the text seems readable though...

that aws an axidental fire. the only problems i see are containing the gas before it is used. before you mow, you would have to collect the gas becaouse it's molecules are extreemly small, they would leak out of almost anything. but i gues it would work, i dunno....

The Hindenburg did not blow up because of the hydrogen. It was painted with rocket fuel. A Google search will turn up all the relevant information.
Really, hydrogen in a combustion engine has less energy then gasoline. It would be an extreme hassle to convert a lawnmower engine to run on H2, and in the end, it will run worse and at lower efficiency. If you really want to power something with H2, get a fuel cell.

LOL. What's even more efficient is to just charge a bank of batteries with the electricity it would have taken to make the H2, and run an electric motor directly from the batteries...

OKay... Thanks for the input.. I'll study more about this... I have a carburator that works on that engine, maybe i'll make some changes to make it work with h2 and make an electrolyser somehow.. Probably this summer cuz i don't have much time now... Even if it wouldn't have much power i would be happy even if it starts...

youll have to build a new carb, you loose alot of h2. use like nnedle valves, a h2 can and a can of 02 and use the valves to ajust how lean or ritch the mix is untill you get it.

| ok first of all i dont think you want an internal combustion engine with hydrogen fuel source as that is just plain stupid. There is something called a fuel cell where current mass production automotive vehicle companies are working on. Its fuel source is water and the exhaust is water so it doesn't pollute except for a couple of gases from the engine. It runs by the electrolysis(i think thats spelled right) of water. It is hard to find detailed descriptions of the engine but you can find it somewhere on the net. And as you can probably tell my train of thought isn't very steady right now |

yea i ve looked at those, i will buoidl obne evntually. the point of using hydrofen in and engine is that it is cool, and a fun prokject. i for one, hava never really looked at efficency on projects ilke this, i just did them to se if it would work and it was fun.

Exactcly cirvin. i don't even want to be able to mow the grass with it i just want to see it start on hydrogen

If you want hydrogen combustion, you're better off with a turbine rather than a conventional reciprocating engine. You'd basically have a hydrogen/oxygen torch with turbine blading in it. Not efficient, but pretty and a fair amount of power!
A fuel cell works by recombining hydrogen and oxygen to form water. They usually work by using a tank of hydrogen and combining it with oxygen in the atmosphere. Water vapor comes out the exhaust. The reason car companies aren't big on them yet is that hydrogen is expensive to make and expensive and dangerous to store. There have been some experiments which use porus iron to stabilize the hydrogen. It helps to keep it from blowing up if a fuel tank is damaged. Unfortunately a big chunk of iron is a rather heavy accessory for a car, so they're looking for better options. One company was developing a fuel cell that ran on gasoline. It combined the hydrogen and oxygen in the gas into water and the carbon into CO2. Not quite as clean as a regular fuel cell due to the CO2 emissions, but still better than burning the gasoline directly. I haven't heard anything about that project for a long while though, so they might not have gotten anywhere with it.

Ive heard of converting a lawnmower to run on propaine...I would think that it wouldnt be to different from modding it to run on hydrogen

Fuel cells don't run on water. They run on hyrdogen.
The so called "electrolosys" engine that seems to be circulating on the Net doesn't work. It's a perpetual motion machine, which, as we all know, is impossible.

It could make a nifty rechargeable battery though! Fuel cell produces water. Store water in tank, use solar power or wind power to energize electrolysis process, converting water back into H2 and O2. Shove back into fuel cell later. I wonder if it would be a good way to store power for a house or cottage as opposed to the usual bank 'o batteries?
