From this story:
"For five days last week in a parking lot in downtown Vancouver, this billboard was lit around the clock by pedal power to demonstrate the energy efficiency of LED lights. The DDB/Vancouver project, on behalf of BC Hydro, required some 120 volunteers — from the client, the agency and local organizations — to keep the 1,500 LED lights aglow. According to BC Hydro, if the billboard featured traditional mini incandescent bulbs, only 120 lights could be lit with the same amount of energy."Via.

That is really cool. I wonder how I could bring such a billboard to my hometown ... and then be paid to man it.
Okay, I WANT to generate the power to make an LED message board on my xtracycle. c'mon, there's gotta be a mass market for it!
