Part jet ski, part electric water scooter, 100 percent awesome. That's the Exoconcept Exo -- a new sea-born vehicle for stealth missions and the occasional run-in with Mr. Living Vicariously. The craft comes in a few flavors with shells made of high-end carbon fiber or ABS plastic, and engines ranging from 3.5-7kWh. Capable of cruising the open waters at a max speed of 15-27 knots (17-31 mph), it doesn't really rival the thrust of some of its non-electric cousins, but it's certainly fast and quiet enough for some reconnoitering or good old fashioned family fun. With four racks of Li Fe PO4 high capacity batteries, the motor powers a water jet turbine drive system to cut through waves without any sound pollution. Unfortunately, zipping around on electric power doesn't come cheap -- at €7,290 (or $9,939), it'll probably only appeal to those who also own the lake needed to enjoy it on. But hey, at least you've got until Q1 2012 to save up!
