QUOTE FROM ARTICLE:
"She then moves us to the next device, a weighty machine connected to a tiny battery. Apparently the load on the machine is a 35kg rotor, which could easily be used in a washing machine. After she flicks the switch, the huge rotor spins at over 1,500 rpms effortlessly and silently. Meters show the power in and power out. Suddenly, a power source of 16 watt or so is driving a device that should be drawing at least 200 to 300 watts. "

Maybe this will actually allow electric cars/trains to be feasable.
Can wait to put one in my RC10, not to mention my HTPC.
 
Wow, site has been slashdotted already. I remember seeing something like this a few weeks ago. Sounds similar to the TMD fan, but on a larger scale. I wonder what the instantaneous torque is on a motor like this. Normal electric motors produce maximum torque @ stall.
