    H2 I believe releases less energy than gasoline, so you would need more of it or have a car that can travel less miles,

    also storing H2 is a problem as its highly explosive and needs to be at -253C to store as a liquid

    Yeah, I wonder what would happen if you crashed the car?

    no... although hydrogen is the most abundant element in the universe... it is too hard to extract... for one, it's economically expensive and two, it's not environmentally friendly as some may make u believe as currently, the pollution created via the energy required to extract the hydrogen would be about as much as driving cars on gasoline and diesel newayz...

    if the container it was in was ruptured, probably yes it would explode

    as the liquid rapid heats up, it will expand at a huge rate then any naked flames/sparks and thats BOOOOM

    but im sure they will design some kind of pressure vessel which can take a fair few "bumps" before it would rupture
     
  8. yes but thats same with normal cars nowadays.. if the tank rupture you gonna have a bigass problem already xD but if you can think of that.. they ofc will find something so it wouldnt be so unsafe

    ^you'd be surprised at how hard it is to get diesel fuel to ignite :p
     
  10. we should try it at the next meeting.. who volunteers?
     
  11. That better be one hell of a vessel.... like a three+ layer of shielding.... inner layer of titanium, middle layer of 3" thick steel coated with another layer of titanium....

    lol 3" steel would weigh very very much and would be very strong, you need explosives to get through 3" steel plates :D
