What a simple, brilliant way for converting energy from stored, grid-based electricity to portable mechanical force.

How much does the equasion change if we realize we don't need to store materials for combustion or electricity, we just need to store up force?

This is smart stuff, and I imagine we'll see lots more of this type of thing. It's like a giant version of the wind-up toy car!

As a truck mechanic I can assure you that air systems tend to leak very easily.

I cant wait to see the people blowing into tubes next to their faces while they're driving their cars on the highway. lol.
