What a remarkable arrangement a hand crank (or, more robustly, a pair of squeeze bulbs that you could compress in alternating fashion to work around any failure in the whole battery->electronics->motor->pump chain) would be: Reacting oxygen with stored chemical energy in muscles, to move air in some tubes, to push oxygenated blood to those muscles.

Though if it can be charged by AC, you'd better believe I'd keep around a Lipo battery pack and DC-AC inverter, and would be stocking up on deep-cycle batteries, diesel, and a generator or two!

Oh, oh, I know this one! What is, “Diaphragm”!

It's really interesting to think about, isn't it! It's not perpetual energy, but there's a lot of room for failure in that cycle.
