Ladies and Gentlemen,
I was reckoning a few years ago... Liquid hydrogen has got such a high energy density - according to me - that you only need to take a couple of litres with you in your car to have a very, very long range... When it comes to an explosion it would be still devastating... So I have the idea to slip the hydrogen fuel tank into an electric accumulator that served as a protective coating around the hydrogen fuel tank... The explosion of the hydrogen fuel would first have to destroy the strong accumulator only then it could damage the rest of the car...
If you burned hydrogen in a 2-stroke diesel engine you would have to take much less fuel with you once again... Because a 2-stroke diesel engine has got a much better fuel efficiency than 4-stroke engines...
Best wishes, Joseph de la Mikula and Team
