Wow.

Just when you thought it was safe to go all gloom 'n doom about the planet, some MIT folks have come up with a coating that lets windows double as solar collectors.

Windows Double as Solar Collectors

Researchers at the Massachusetts Institute of Technology have developed a system that turns windows into a solar collector, letting people see clearly while collecting energy.

A coating on the glass channels photons of light to a solar collector around the edge of the window, MIT electrical engineer Marc Baldo and colleagues report in Friday's edition of the journal Science.

The  window coating absorbs the light and transmits it to the glass underneath. The glass then transmits the energy to solar cells at the window's edge. The coating comes in various colors or "almost transparent."

Per the Science article authors, the technology is not that expensive and can be added to existing solar panels. The Yahoo arrticle did not clarify this point--by hooking up window edge collectors to exisitng systems (not existing panels--don't see the point). I am a layperson--maybe someone else can jump in?

best news is that the technology may be market-ready within 3 years. Given the price of oil, I wouldn't be surprised if they rushed it to market even quicker than that.

I'm always happy with new solar news, and this seems as if it may be more helpful than the solar bra and solar pet clothes (I kid you not) that I've seen discussed on the Web recently.

Hooray for alternative energy!

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
