Due, you are close to being sued for patent infringement on the original Rouquayrol diving system.

I am assuming the pressure regulator is a manual setting and that is where the risk lies. A Scuba second stage adjusts the delivery pressure to match the pressure at the depth. This provides natural breathing and prevents lung over expansion.

With a manually set delivery pressure you could rupture a lung. Thjs can happen with as little as a 4 foot (~2PSI) error. For that reason this is really dangerous. If you included some sort of trap or vent on the diver side you could potentially vent excess pressure and still manually provide air flow on demand with the trigger.

The buoyancy properties of the cylinder would alse be misserable.

Pah....not impressed. When I was a teenager, my little brother built an apparatus made from a water canister, some PVC piping and a few valves, everything from a home improvement store for probably less than 10 bucks. This thing worked like a charm, and it delivered air at ambient pressure. The only limiting factor was the pump we used - the kind used for inflating kiddie pools. It was made from plastic and not very sturdy. The deeper the diver went, the harder it became to push the pump handle down. But even with that, we took this baby down to almost 30 feet and it worked great. I wish I had pictures...

My Dad made a homemade hardhat rig back around 1940. He used a square can with a window installed in one side for the helmet, and used a bicycle pump with some kind of a pressure tank on the surface. My mother would stay in the boat and pump. I think he only went down to about 30 feet or so.
