Who killed the air-powered vehicle?
- aurizon 6y agoCompressed air has only 10-15% efficiency end to end. Best case is compress with electricity - about 93% efficient. Then cool the hot compressed air to reduce the pressure to get more in the tank. This cooling wastes about 10% we are now at 73%. Expand in a 3 stage expansion engine to get rotational power.Compressed air expansion is a carnot type engine andhas about a 30% efficiency that falls to zero as the tank expands the air and the internal pressure drops to local pressure and the engine stops.Total efficiency 10-15%. They are used as factory jitneys where the use compressed air and it intrinsically safe - no gas/diesel spark or flame. The idea is 150 years old or older. Diesel/gas and batteries killed it and keep it dead
