I have alot of ideas. Water is an amazing substance and there is no way we could live with out it. but with all these ideas i search on the web everywhere can cannot find the answers i desire. so heres your questions. have fun answering them. 1. with pressure and heat combined at what cc compression and F degree does water turn to steam instantly? 2. whats the expansion ratio of water turning to steam in volume? 3. hydrogen alone has been considered "unpredictable" during ignition, what about a stiometric(sp?) mixture? is it always stable? 4. why can hydrogen and oxygen exist together as gases but when ignited turn into water? is it like the same thing as nuclear fusion only on a very smaller scale? i have many more questions but the main reason for all these questions is because i want to make a "super" engine. something that will produce an insane amount of power, electricity, thrust, ect.. without any disasterous outcomes (or else i would be using tritium and uranium =p) anywho. final conclusion. i want to go really really fast. fly. without paying a cent for gas because water is renewable. i've experimented with magnetism as well but i dont understand all the aspects about that as well.
