[PSUBS-MAILIST] Vessel Registration

[Alan James via Personal_Submersibles]

Hi Mark,I posted on Psubs Facebook page.Are you still on Mindinau Island?
The idea is to come to the surface with thrusters & draw air in through a snorkel.The thought is that you could replace 2 scuba tanks with a blower & save on space as well as having a lot more dives before needing to charge batteries, as apposed to filling tanks.Have a back up air tank for emergency air & blowing of ballast tanks.A lot more convenient, & less expensive. What I am trying to figure out is what is the best type of fan to use. A conventional fan or the squirrel cage type. Also what speed and hp I would need to aim at.One of the problems I can see is buying an appropriate fan blade.Perhaps a blade off a high powered vacuum cleaner & matching it with a DC motor.Alan
