   Some people are stupidly on about putting wireless charging into the   
   roads so the cars charge as they go along ... immensely expensive and   
   distributive.

   You don't need to transport and store large quantities of hydrogen -   
   just water and then create hydrogen (almost) as needed.  :-)

   Nah. Just use the waste cooking fat from all the McDonalds stores ...   
   or at least you could of until the "obesity epidemic" fanatics started   
   causing McDonalds to become Salad Town.
