Interesting!
Issues:
1. Air springs are very inefficient, though. Absorb energy.
2. Must be a catalyst in there somewhere for the fuel.
3. I don’t think linear generators are as efficient as rotary, also.
But cool tuff!
—”1. Air springs are very inefficient, though. Absorb energy.”
Not my line of work, just asking.
If the air spring is not leaking and adding pumping losses, where is the efficiency lost?
