Title: vacuum for HHO gas generation
Post by: kent on November 15, 2005, 11:02:30 PM
Has anyone every thought about putting a hydrogen generator in a vacuum? would you get more output? any ideas?   ???

I think it will improve the electrolysis process.  ;)

Watch this!! http://ie.youtube.com/watch?v=7tH13Vfv-Lc

As you can see, the brown gas quantity increase dramatically.

Here's how to build a vacuum pump by your own. It use a small tire inflator to generate vacuum.

Or , maybe you want to make a better one......  It use a old refrigerator compressor.

? depending how hard a vacuum you pull you may be just evaporating the water, any refrigeration web page will give you a temp/vacuum chart for water. It would be interesting to look at the drop in temp or not when the vacuum is on. I guess that when the vacuum is on and gas is evolving the available surface area is reduces so hence the current is also down,  remember the gas volume also increases in proportion reciprocal of the vacuum, this not to say a greater mass of gas is produced per watt input.
This is on my to do list once I have my blast shield in place!

Best, HTwoGo

Yes, this guy shows it quite nicely:

I guess,if you don?t make the vaccuum too big,
then you will not evapourate just the water, then you will really
get more HHO gas.

If you still would pump the water more through the pipes,
also the current will not go down so much and the bubbles
will be removed even faster.
