All the time and money we waste on compressors and fill stations, these people can fill a scuba tank with a bicycle pump!

Even if we assume a divemaster physically powerful enough to compress 3.5 cubic feet of air to 3000 PSI with a bicycle pump, they'll need to replace the fill inlet with something other than a 150 PSI shop air connection. 150 PSI in that bottle is probably around a tenth of a cubic foot and while enough for a possible expansion injury, not enough to actually swim around.
OK, so if we replace the fill inlet with a high pressure yoke fitting and genetically engineer an 800 pound behemoth divemaster to pump the bicycle pump at .25 CFT per minute at 3000 PSI, it could work right?
Even if the bicycle pump thing doesn't work out, I'd still like to get my hands on one of their compressors. Apparently, it's under 40 pounds and can deliver 1.5 cfm at 3000 PSI from a 12 volt inverter. Sweet!
