I like the air brakes example, but it is single use, so not much energy. But are machine shops ever really run with stored compressed air (besides the surge tank?)? Are there portable air tools?
Yes there are. For safety in explosive environments though, not for energy storage aspects.
Laminar flow - i meant when process/flow is stable, constant across the length of pipe.
In essence, i hoped dissolved gas phase transition would give additional usable energy(idea from decompression sickness).
Anyway, apparently this doesn't happen spontaneously(for example with underwater volcanos), so no cake here.
Back to clathrates i guess (:
