This isn't a billboard. Its a power plant!
San Franciscan Pacific Gas and Electric, California, has just installed the first solar powered billboard in the world.
The billboard actually draws power from the grid, but the power output of its 20 PV panels is higher than what the billboard demands from the grid, keeping the balance positive. This is also possible due to the high efficiency LEDs the billboard uses for lighting.
Ranging from 2.5 to 3.4 kWh electricity produced during the day are actually close to what is necessary to power one family house.
Is this another great idea or is it just not worth the investment?

I wonder if they will use the new ultracapacitors for energy storage of these PV panels? I like to see this new clean energy wave.
