[Justin Beckerman] developed a working one-man submarine. The thing is, this isn’t the very first one that he’s built. Looking with the jobs on his web site we discover nearly no info about this build, however he does show off one previous model, in addition to a couple of unmanned underwater rover projects.
The pressure hull of the sub is made of corrugated drainage pipe. This isn’t a poor concept as the tube is engineered to be buried in the ground as well as bring the tons of earth on top of it. It’s created to go down just 30 feet, which describes the lack of half-dome caps on either end; the pressure just isn’t that fantastic at that depth. The buoy floating to his left is his tether to the surface. Fresh air is pumped from right here into the sub. He’s likewise included safety features like a 20-minute air storage tank in situation he gets into a bind, as well as a quick opening top hatch. That hatch is a hemisphere of remove acrylic which lets him view what’s around him.
You’ll discover a lot more from the two video clips he posted. The Fox 5 news interview includes a shot of one of the messiest work benches we’ve seen. A untidy bench is the indication of constant job construction, right?
