The air car would also weigh a lot less so it would take far less
energy to move it a mile. They claim 112 and 137 miles per charge. The
cost per charge they claim would be one Euro or around $1.27. I like
that.
If as you say this would work with a bus or other large vehicle why
would it not work for a car?
