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...

Ah, that explains everything. Always the lowest bidder... *space shuttle* *cough* *cough*

I remember hearing somewhere that it was the cheapest available...

I blame the Hindenburg for all the bad press hydrogen has received. It's not the hydrogen's fault that the hindenburg was covered in an extremely flamable paint. I wonder how they managed to decide to use that particular paint anyway? Did they just not know how flamable it was or something? Crazy.

You know what? Hydrogen is VERY difficult to ignite in the open. You could get a 10LB H tank, put the valve wide open in your driveway, and still not get it to ignite. And it is very difficult to enclose hydrogen and make it build up since the molecules are so small...they diffuse out of almost eveything.
Hydrogen is actually several orders of magnatude safer then gasoline....I'm really sick and tired of people parroting what they hear in the media about hydrogen, and doing nothing but spreading FUD (fear, uncertainty and doubt) due to their own ignorance.

OOkie then Cris, you design and build the project, come over rig it up to my lawnmower and i'll be a few meters away from you behing a concrete wall when you try to start it...

sory a bit late for ths one, but the hindenburg's skin WAS rocket fuel. it was a cellulose fibers with aluminum woven into it. solid rocket fuel

OK here goes- 1) Im not into precision when it comes to stupid projects..... 2) there is a way to produce a LOT of hydrogen through a chemical reaction between caustic soda(dont want to get any on your hands tho! lol) and strips of aluminum here you guys check out this site:
http://www.fortunecity.com/greenfield/bp/16/jacksongas.htm
i want to make a simpler version of that; larger metal container filled with aluminum strips and then quickly with caustic soda/water and closed with a lid that contains a tube equiped with a one-way :) valve which goes to a simple valve to regulate gas flow which in turn goes into the intake pipe for the lawnmower(where the card should be) and hopefully ill still be able to walk the next day

There are a number of homade fuel cell plans on the Net, as well as kits. Alot simpler them most people assume...

Aren't those membrains expensive, plus the controlling mechanism would be critical...

it is much too efficent. and how csn u build one?
at last!!! |

True, but when I do a project, I like to have a usable result. A hydrogen lawnmower engine is neat, but won't have enough power to mow the lawn, and refuelling it will be annoying. Instead, why not buy or build a fuel cell?

"why" has been awsered. to se if it can be dome and too kep urself occupied. if you hav to ask, youll never know.
next stop: nobel prize winner! |

Should work fine for all basic gas engines. You need the PWM circuit to control your fuel injection and keep the mixture correct. Just putting a regulator directly to the carb will allow the engine to run if you manually adjust the mixture, but you don't want to do this. You would have to make adjustments any time the load or speed of the engine changes, as well as compensate for temperature, etc. A simple PWM based on three outside inputs (vacuum signal, RPM of engine, throttle position) is easy, and there are probably ICs already around to do this.
But again, there's the "why?" factor. Seems to be an aweful lot of trouble to go through to make an already inefficient engine less efficient, with a fuel that is difficult to obtain.
