	Great on the surface, and excellent if compressed air is generated by using renewables, or even by hydrolysis of water to generate 2 fuels: hydrogen fuel and compressed oxygen for air cars? If renewable biomass is used as fuel to drive compression, it is more efficient to use the fuel directly in a combustion engine. A case can be made for renewable charcoal biomass as a sustainable fuel wherever biomass is abundant. But the qeustion is - should we make compost for soil or burn the biomass?

If biomass is missing in soil, we should compost biomass.

	Comment by MJ - Great potential. What issues does it solve? 1. Fuel storage via air. 2. Clean burn. Disadvantage: Air is not so efficient - they are claiming 70% expansion efficiency, with compression up to 60% efficiency - so at best about ~40% efficient. If compressor is driven by a 30% fuel engine, that is about 10% overall efficiency.

	Comparison from the accessibility perspective: renewable char gas from coppiced permaculture plantings appears to be more sustainable in terms of local energy production from a living ecosystem. If energy is obtained from renewables such as wind, the air engine would be a great case for the car.
