I see a way to make an efficient heat engine. I want to get it designed and built. I don't care about making a pile of money from it, I just want to solve the energy problem so I will be able to get a car without being a hypocrite. Living in NYC was nice but too expensive. Living where I am with no car is cheap but the bus service sucks and the hills are too steep for bicycling in bad weather
Leveraging always beats prototyping.
