apartment therapy changing the world, one room at a time

This story was brought to my attention by a friend who's a VT alum. It's really a great concept and I'd love to have one. You might notice though that all the images are renderings, and there's no mention of a prototype. My guess is that you won't see this take off anytime soon - because there's no way it will work with current technology.
Clicking through to the project page on core77 explains that it is powered by 5 10-lb weights - 50 lbs, or about 25kg. The weights travel 4ft in 4 hrs, or approximately .000085m/s. P=mgv=0.021W. There are 10 "high output" LEDs in the system, so each gets 10% of that power, meaning a typical 2V LED draws only 1mA of current. For comparison, a typical flashlight LED draws 350mA to produce 80 lumens (total output of the Gravia is 400-800 lumens, so figure half this current draw).
It's a great concept, but it looks like the people giving out the prizes didn't do the math on this one (or, as somebody pointed out on Slashdot, it's a design competition, not an engineering competition).
