lol, liquid hydrogen freezes at "Freezing Point @ 1 atm: -434.5°F (-259.2°C, 14oK)"

Well, thanks for the positive feedback guys. I really do appreciate it. How could I store Hydrogen as a liquid? @Ragnarok Yeah, HHO Cells are ran off of the battery and triggered off of the ignition switch, or separate switch. It is only ran off of one battery when using it WITH gasoline. But if it ...

A gallon is 4.5 litres, so it would last 4.5 times as long. However, I do have to express my doubts that an engine could be run on only 5 litres of HHO gas a minute. Thinking it through 5 litres of Hydrogen gas at 10 psig will only release 30 kJ of energy when burnt. A 220 hp engine has a power out...

Thanks guys, Lentamentalisk, you answered my question almost perfectly. Except, I would use a 22 'Gallon' tank not liter, what would it be then? And I didn't think about storing the gases in two different tanks, that would be a lot safer, lol. Oh, and while driving, a series of HHO Cells would be cr...

Okay, I'm working on running a car on nothing but HHO gas (hydrogen2 and 0xygen1). It takes 5 liters per min of HHO gas to run a 220hp motor at full speed. My setup I have written down, takes HHO gas, formed from electrolysis, and compresses it into a 22 gallon tank, at 30-60 psi. What I really need...

Quick advanced question about a psi question

If I had a 22 gallon tank, and hydrogen compressed to 60 psi, how long would 5 liters/min flow out of the tank at 10psi? Sorry if you can't understand the question, if not, just ask about it and I'll try to expain :-D. Thank you everyone who helps me with this.

Is neoprene rubber the same thing as bike inertube? Because I have plenty of bike inertube! :D

Lol, I already started a thread on this about a week or two ago. I haven't gotten any chances to test out the different variables though.

I'm using a 1 1/4" coupling as the piston, and a piece of foam stuff from some case. The foam is air tight, but there is a hole in it in the center... so air is leaking from underneath the foam through the hole. I just need a different.. sealing plate? I guess you could call it that. Any ideas? Some...

The 1.5" piston porting is on the very small size for a 3" barrel. Lemi do da math... The piston has about 1/4 the flow of the barrel. It should work fairly nicely for a 2" though I only wanted the 3" barrel for small toilet rolls for Halloween! :D spudgunnerwryyyyy: I'll post pics of it as soon as...

Yeah, I thought about that. But it won't be pressurized very long plus I'll mainly be shooting my dad's beer cans with a wad of rag behind it. And I'm going to get a coupling for a 2" barrel soon too.

i know that, but that really won't matter much because it isn't being pressurized.

Lauren (revised) V2

I finally finished the new version of Lauren. This time around I used all pressure rated parts, and a piston valve (which will be piloted later by a sprinkler valve). I haven't got a chance just yet to fire it because of sealing problems with the piston. But, it has a 4' by 1 1/2' chamber, 2" piston...
