Mangrove WinMo tablet rough-handled, teased for being 'tubby'








We've see plenty of green power research over the years, from solar plants to underwater turbines , but relying on the sun or the sea for electricity is not without its challenges: the sun doesn't always shine, for instance, and sometimes the water is calm. A group at MIT led by professor Donald Sadoway is developing grid-scale storage solutions for times when electricity isn't being generated. Since these batteries are intended for the power grid instead of cellphones and Roombas, the researchers can use materials not feasible in consumer electronics -- in this case, high temperature liquid metals. Besides being recently awarded a grant from ARPA-E (Advanced Research Projects Agency, Energy) to put these things in green power facilities, MIT has just embarked on a joint venture with the French oil company Total to develop a smaller-scale version of the technology for homes and office buildings.

We can't all be a Witwicky, owning a badass robot able to change from sportscar to hulking humanoid. Some of us have to aim a little lower; enter the XOR X02 Urban Transporter. It's an electric scooter that can fold into a little cube for easy storage (shown after the break) and attaches to a luggage cart to be wheeled away -- just keep in mind that at 50kg (110lbs) it's not hardly suitable for overhead compartments. There are three models, the lowest being the X02-50 with a top speed of 37mph and a maximum range of about 40 miles. Highest spec is the X02-125, supposed to deliver performance like a 125cc scooter, a maximum speed of 65, and "impressive accelerations" -- performance comparable to the Zero S or Brammo Enertia. Charging takes just two hours and they actually don't look half bad, providing a nice mix of retro scooter and futuristic urban transporter. Just the same, you probably wouldn't want to show up at any robot uprisings on one.
