Building and Testing an Underwater Jetpack

Okay, so calling it a jetpack might be a bit of an exaggeration... But I gotta say, effortlessly gliding underwater around the speed of an Olympic swimmer is a pretty cool feeling. Took it down about 25 feet in this first test in Lake Charlevoix, Michigan, and found that it ran for about 30-45 minutes on a single charge.

Where should I explore next with it?
Any ideas how we can make it go faster with a different prop design?
