Well they have claimed a range around 100 miles and speeds up to 45/55 MPH.

And you could refill it at home in about 4 hours, about the same time to recharge an all electric car, and if you ran low on the road stop at a gas stations and get a partial refill to get home. (I can remember in my youth nursing a water leaking car home stopping and string of gas stations to refill them)
Good idea??

Will it work?? There are a few problems.
The original Air Car few years ago was show being road tested in Europe, and they claimed that with a gas tank for heating the air they could build a car/mini van that could get 100MPG (Of the 10 gal. tanks of gas) which would give around 1000 Mile range on a full pair of tanks, one air and the other the heating gas tank.
This was THEIR claim
Sadly there seems to be a number of problems to over come:
