First let me say this. these guys are MIT graduate and been involve on some of the speciall effects done for movies. From I recall they found an electrolyzer plan from the internet they called "internet Patent", an old design but still a good plan. I like how they showed they were making a special way to power the cell. No need for that. The configuration they used was two, hopefully stainless steel tubes one lager than the other so they can be inserted into one another. submerge them, hopefully it was distilled water with some form of electrolyzer KOH or even salt and the size of the cylinder they to put them in, from what I recall it would have held at least a gl. or so of water. Then all they had to do was induced 12v power to it negative to one tube and positive to the other it did not matter which one. that tube should have been poluted with bubbles from the hydrogen and oxygen being created. The amount of amp it would have consumed was determined by how strong the solution they mixed. they did not disclose that, because they did not use the proper mix recommend from the designed they use.
They did not clarify all of this in their show. when I said you don't need special way of powering the cell. just apply 12v. If my 9 year old can follow the chemistry set I put together and produce enough hydrogen to produce a flame from water. then those educated group should be able to the same.
Oh yeah take an old car without any gas and expect to fire it up just from hydrogen, Okay, one hydrogen is used as a hancer, hence hydrogen boosting to enhance the combustion process. Here's the mistake and I am surprise it was part of the show and it did not blow up in their face at the time. Take a highly compressed hydrogen and then feeb a ICE with it without any modification to handle the gas and expect it to run, long enough to drive.
The process has evolved a great since that show was made. cell are smaller and easier for the average person to install in any car or truck experience the benefit from the process. Yes hydrogen has it's history of blowing up, this process you almost have to be stupid enough to introduce a flame next to it to blow things up. The only things that is hard to over come this days are the electronics involved in the more modern cars. the older vehicles which most of us drives are easy to accept HHO boosting.
I am not here to start a long debate over is it a scam like many have stated or is it a solution to our growing needs to combat rising fuel. Change is always hard to accept specially when it involves making something better and we don't understand it completely.
Reminds me of when I used to use a battery charger with the probes in an acid bath to create O2 and H. You put the probes inside a Coke bottle (when they used to sell coke in glass bottles) and capture the gasses by displacement. Cork it. Light a candle, uncork the bottle, put the opening of the bottle next to the flame and
