Stick it where the sun shines:

A Swiss entrepreneur says his thin-film solar panels will provide power more cheaply than fossil fules within five years:

Even though solar technology has made significant gains since the 1970s when it cost $100 per watt (now it’s $3 to $4 per watt), that sweet spot of beating out fossil fuels is $1 per watt. Swiss entrepreneur Anil Sethi says his solar foil can hit that magic number for even less than that — $0.80/watt — within five years and beat the cost of fossil fuels by 50% in 10 years.

These thin films can be attached to the sides of buildings and work even on cloudy days.

Sounds promising!
