Nanosolar
My oldest son has been subscribing to Popular Science for years. When he was in high school I heard about the latest technologies third hand; the magazine disappeared into his room as soon as it arrived. I never got to read for myself about solo powered air flight, electric cars, and nanorobots. Now that he is off to college I get to read it myself. It is like reading a science fiction novel but it’s real: New gizmos and gadgets that would make the Jetsons take notice.
One perennial topic is solar power. Now I’ve been watching the development of solar panel for years, at least since I was in high school myself and clipped a solar cell to a bulb from a flash light and got a dim glow. The past few years have been particularly interesting. Several months ago I was invited by one of the investment banks on Wall Street to hear from the entrepreneurs on the cutting edge of this promising technology. They talked about new breakthroughs in materials science and design, but all delivered essentially the same message: We can produce power from the inexhaustible rays of the sun, but it will be many years before the cost of solar power is competitive with electricity from conventional sources. Translation: Give us some more investment tax credits and give our customers some tax incentives and we can do more.
So nowadays when I see a story about solar power I usually yawn. That is, until a couple days ago. A story in the Sunday New York Times caught my eye: “Start-Up Sells Solar Panels At Lower-Than-Usual Cost.” Now I’ve heard this claim before so I scanned the article quickly with the intent of going on to something else. That is, until I saw the “Lower-Than-Usual Cost”: $1 per watt. Whoa, I said to myself. That’s cheaper than a new coal plant!
It appears that a new company in California called Nanosolar has been launched with backing by some Silicon Valley sponsors including some of Google’s co-founders, according to the story. The company has built a factory which, it says, prints photovoltaic material on aluminum backing, reducing the cost of solar panels by more than 80%. In other words, with this technology solar power can produce cost effective energy for the first time since Prometheus stole fire from the hearth of Zeus. (Let’s face it, can’t get it much cheaper than stealing it – not a good thing, mind you, but it sure beat freezing in those long nights on Mt. Olympus.)
I haven’t been able to stop thinking about Nanosolar’s new idea. It has the power to truly change the world. Sure, solar power cannot supply all of our power needs, unless we all plan to move to the Mojave Desert and go to sleep each night at dusk. But imagine if solar were efficient a mere 10% of the time. That would be enough to provide all the electricity we need to grow for years, certainly until new nuclear power plants are designed and developed. In the meantime, it could reduce our current dependence upon fossil fuels, thereby reducing harmful carbon dioxide emissions from natural gas fired generators and sulphur dioxide emissions from fuel oil and coal plants.
I used to like science fiction as a kid. Jules Verne’s “Trip to the Moon” was fiction until it became a reality. Isaac Asimov’s robots were fantasy until they appeared on the General Motors assembly line. The Jetson Family’s solar powered home was a cartoon…until Nanosolar. As one who lives and breathes energy on a daily basis, I feel like a guy riding on horseback when Gottlieb Daimler passed in his automobile, lurching and backfiring over the rutted road.
Now if I could only get my hands on one of those solo powered aircrafts.
