We've discussed this at length here before.
Their business model is very shady, and the efficiency is just not there.
Too much of the power inputted is wasted as heat.

Costs nothing? Of course it cost money. Money in electricity to compress the air into the tanks. An air tank is just like a battery, but it's energy per weight and volume is meager and they're more dramatically affected by temperature.

Complete bull****.
