If you can use the heat of compression for home heating, and re-warm the air with huge heat exchangers on the vehicle, between expansion stages, you can get some of the same over-unity efficiencies we see with heat pumps. However, the Air Car people ignore the danger of air tanks. Needing no oxygen mixing to release their full energy, they are like high explosive. Historically, air-powered vehicles in mines have had a short range, despite steam-boiler sized tanks.
