How is compressed air any different from houses with large natural gas tanks? My father in law bought a house with some property and no gas like. The tank is like 20+ years old and it’s filled every few years.
Compressed air is way more dangerous than liquid fuel. Liquid fuel needs oxygen to burn, so it is slow to start and prone to starving itself. All compressed air needs is an undetected defect in the tank and it will turn into heavy knives flying at supersonic speed.
