A Tesla Model Y weights about 2 metric tons. Out of these 2 metric tons, about 40% is the battery. So it is not entirely wrong to describe a Tesla Model Y as a battery with wheels.
Nathan Myerssays:
Such a lithium-air battery might fundamentally change the economics of aviation, particularly if they could be swapped in and out quickly, to be charged off-line.
Current battery energy density is more-or-less sufficient for ground vehicles.
Such energy densities would make electric aviation a real possibility beyond a few hundred km.
