Vacuum and heating a WFC
« on: June 03, 2008, 15:02:16 pm »
Ok,

A new topic about pulling vacuum on a Waterfuelcell.
here is a link about a person who shows how he did it and he got lots of gas.
The question is if this gas is HHO with or without watervapour.
The results are very good.
He preheated the water till 76 degrees Celcius and then he put the vacuum on it.
The vacuum lowers the boiling point of water, so it vapourizes.


Lets followe this techic and see what it can bring towards gasproduction numbers.

Yes CN,

That also shows some good results too.
Any suggestions on how to pull 29 inches of vacuum?

Get a vacuum pump.  There are a few different types of pumps. I've used a 12v8ADC powered .1hp diaphram pump and was able to pull 22" of mercury. I've seen some people with mechanical air/vacuum pumps, I have limited experience but I think those might be over-powered for their application.   I did like ZeroFossilFuel's paint sprayer video where he shows you his vacuum pump. Its just a paint sprayer but it runs real trick and he explains it where the load on the motor fluctuates when it is under a load....  $.02

When you put a vacuum to the cell the bubbles expand.  The white froth you have at the top will almost instantly become two or three times thicker. The bubbles that come from between the tubes/plates pours out as large bubbles which flow at high rates of speed upwards.

I'm not sure of the reaction which is occuring while the vacuum is applied.  The large bubbles happen when 15" and up of mercury are applied.
These large bubbles do no not have the same explosive power.

...Any thoughts?

I think if you pull too much vacuum, the water will boil inbetween the plates/tubes because of the electrolosys process. Its sweetspot would be just before the water boils. The water dosent seem to boil when its UNDER 15" of merc.

Cn,

can you confirm that the extra bubbles are just vapour?

What kind of vacuum pump? Try this: Impact Instrumentation (Caldwell, N.J.) MDL # E-12, 12 vdc, 8.0 amps. You'll need to put a pot on it to control the speed. It will pull over 30" HG. Used in ambulances for pure oxygen. Works great! Make sure you use reinforced tubing. Voltar
