it's actually not a scam.. and my friend runs one in his car that I personally seen. He runs a mesh plate water cell. I have a dry cell that doesn't go into water.
I've already used my cell to make a hho torch.. hydrogen burns... this is not a scam...
over 45 patents don't tell me scam... do some research!
the fact that article refers to gasoline as a fossil fuel when it actually isn't connected to fossils. also they only focus on the water4gas website which still provides a crude hho system.. but will probably harm your car because of how poorly designed it is.. to me they are biased.
