New Solar Power Design...using polymer foil?

Postby Ed Ziomek » Sat Jun 30, 2007 10:04 pm

Ethanol lately is getting a bad rap, though maybe deservedly so, saying that the carbon footprint in its production rivals fossle fuels, and it is only 80% efficient...80 cents to produce, for $1.00 worth of power.

Solar enthusiast are now mentioning a solar powered alternative and rival to wind and ethanol production....using a polymer foil substrate...

Cheap solar power poised to undercut oil and gas by half

By Ambrose Evans-Pritchard

"Within five years, solar power will be cheap enough to compete with carbon-generated electricity, even in Britain, Scandinavia or upper Siberia. In a decade, the cost may have fallen so dramatically that solar cells could undercut oil, gas, coal and nuclear power by up to half. Technology is leaping ahead of a stale political debate about fossil fuels."

and...

"The "tipping point" will arrive when the capital cost of solar power falls below $1 (51p) per watt, roughly the cost of carbon power. We are not there yet. The best options today vary from $3 to $4 per watt - down from $100 in the late 1970s.

Mr Sethi believes his product will cut the cost to 80 cents per watt within five years, and 50 cents in a decade."

This would seem to be wonderful news.

My own concern is the mathematics... "$1 per watt"???. That seems to be a misprint... A lightbulb is 70 watts per hour, am I correct? So it would take $70 to light a lightbulb, per hour?

And of course, there is the age-old... "What stopped all of us doing this 20 years ago, and what is stopping us now?"

Two more references, including a very interesting comment on investment partners....

"With the investment dollars of Google’s founders, Nanosolar is building a plant in California the capacity of which would catapult it into the top solar makers in the world."

"The FLISOM technology is based on the concepts that led to the world record for light-to-power conversion efficiency of solar cells on plastic, developed at ETH Zurich. "
