I looked into building a compressed air remote controlled boat for fun, to use on a nearby lake where I was worried about putting batteries on something that might sink.
It is monstrously inefficient. A scuba tank might power a vehicle for a half hour tops, though I forget the exact numbers. Scuba tanks are huge and heavy for small hobby vehicles.
I'd love to pick it back up are there other options here?

Higher compression. Scuba is older tech and standardized around relatively low pressures. CNG runs above 3000psi. Paintball guns run air at 4-5000. Carbon fiber tanks are readily available for both as are compressors.
