Personal, Rechargeble Submarines Hit

Oh, man, this is cool. The Dutch company U-Boat Worx is selling one-man and two-man C-Quester SUBMARINES. The C-Quester keeps you totally dry inside, and dives to a maximum depth of 150 feet -- 50 percent deeper than the recreational scuba diving limit -- and has a safety system that won't let you go any deeper. Best of all, the air pressure inside remains constant (the surface pressure), so you don't need to worry about decompression (or decompression sickness). You can stay underwater for 2.5 hours, although the subs contain enough air for 36 hours underwater. You can recharge the batteries in 12 hours. I want one. (props to Engadget and bornrich.org)
