Challenger deep is a home built one person submarine. It is able to dive to a depth of 100 feet and can travel at a top speed of 3 knots. It weights 3,800 lbs. I completed the build in 2007 and have more than 50 dives to date.
As a you man I was inspired by Jacques Cousteau and I have always had a passion for build things. This is just one of those things. Currently I am working on a renewable energy project that has me excited.
