our motor runs on 5% petrol 95% water Although it runs better at 20% we got all the info off the net, spent $100 on fittings & 1 day to build. no one could have been more surprised when it started, the only problem we have is controlling the engine speed & it,s noisy but it,s very powerfull we already mow our lawns with it. Were thinking that in automotive use you would have to run a constantly variable transmission???? our next step is to get a car engine running on it (3k of course) Electricity seems like a bandaid to me, the ideal power source is magnatism, it,s all around us , we just have to control it but seeing as i,m flat out getting a mower going i might let someone else figure that one out. I read an article that their is a million trillion litres of fossil fuel still under the ground, do you think they are going to find an alternative till they,ve used all that up, no wonder all the inventors are dying mysteriously
