Solar cell breaks efficiency record
Michael Kanellos, CNET News — December 6, 2006
Boeing-Spectrolab has developed a solar cell that can convert almost 41 percent of the sunlight that strikes it into electricity, the latest step in trying to drop the cost of solar power.
Potentially, the solar cell could bring the cost of solar power down to around $3 a watt, after installation costs and other expenses are factored in, over the life of the panel.
[…]
Current silicon solar cells provide electricity at about $8 a watt, before government rebates. The goal is to bring it to $1 a watt without rebates or incentives.

We’ve been going through this for some four decades now, and it’s gotta Stop Now, but I doubt it will, because it comes mainly from those that don’t serve as they wrap themselves in the banner of a political party that’s “Strong On National Defense” while condemning all others as not! It’s in their political ideology to be used and accepted by those that claim that ideology, like they found great enjoyment wearing and laughing about “purple heart bandages” not long ago. Even some who serve, and do so in our wars and occupations of choice will use it, strickly as their political meme, disgracing their own service as they attack their brothers and sisters, never having real facts to back up their claims, and never apologizing especially to their brothers and sisters!
