Exoconcept EXO all-electric jet ski: perfect for lake recon, your next indie action film
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!
Gaming consoles' hidden costs
DXGaming.com set out to determine the energy costs of popular gaming consoles of today and yesteryear. Not surprisingly, DX Gaming found that Xbox 360 is making the largest contribution to your energy bill, costing as much as $20.10 per year to power -- compare that to the 92 cents (today's rate) needed to fuel the original PlayStation. Interestingly enough, Xbox 360 is also the most energy efficient console, squeezing higher performance out of each watt: 61.21Mhz / 1 Watt. The GameCube ranked second at: 30.81Mhz / 1 Watt. Also worth noting, for you penny pinchers, if you unplug your consoles in-between uses, you'll likely save a couple bucks worth of 'leaked' energy annually -- that goes for cell phone chargers and other electricity-dependant devices too. But please, don't unplug the 'fridge before going to bed.See also:Joystiq readers are environmentally friendlyJoystiq poll: Do you leave your game console on standby?
