The next big thing in clean tech?

(continued from previous page)

• Metrolight: The company essentially makes processors and software that can replace the traditional control systems in High Intensity Discharge, or HID, lights used in streetlights and fixtures in stores. By more acutely controlling the electricity going to these lights, power bills can be cut. Lighting consumes 20 percent to 25 percent of all the electricity in the industrialized world, according to Metrolight founder Yigal Yanai. The company's revenue over the last 12 months came to $3.3 million.

• MWOE Solar: CEO and University of Toledo professor Xunming Deng says he can cut the costs involved in manufacturing amorphous silicon solar panels by 90 percent. (Most solar panels employ rigid crystalline silicon solar panels, which harvest more energy. But flexible amorphous silicon panels are growing in demand.)

Deng, however, would not describe how his company can reduce the costs in this manner. The only clue he gave was that MWOE's panels incorporate silicon and germanium, not just silicon. MWOE has an exclusive license on the technology from the university.

• TecHarmonic: Although not a huge contributor to global warming, semiconductor manufacturing requires a number of chemical gases. TecHarmonic makes equipment that eliminates those gases. The equipment can also be used at disk drive and solar factories to abate regulated gases.

Why the most promising company is not listed?
Where is Changing World Technologies, Inc. in this story? They are the most promising company that can deliver on cleaning up the environment(municipal waste) and at the same time provide clean byproducts such as crude oil, minerals, etc. And this is not a theory. Several pilot plants are operational and running. By the way the plants are self-sufficient, make profit and do not pollute. And, no I do not work for this company. Just very interested in their work which I think is the solution to our dependency on oil and our environmental problems. If only our representatives in the govt. would do something to help out with this promising technology.
For more info check out their site.

Thank you for your time.

Good ideas
I think all are good ideas but I don't necessarily agree with Clearfuels and how to not go to Municipal Waste. Waste is toxic or harmful and needs to be eliminated. It would be nice to have a company try to tackle on waste by-products as well so that we can have less of it.

Especially now that we have over 5 billion people in this world let alone corporations producing their fair share of waste.

Light sensitive glass won't be...
... truly efficient until researchers can figure out how to make it whiter (to reflect heat) instead of darker.

so much for that window office...
I guess this will also cut down on the braggin rights for having an office or work desk with a window view. Neat.

do windows turn dark or do they reflect?
It don't see how window glass "turning dark" will save energy costs. Maybe they mean "turning reflective?" On a hot summer day with the sun shining brightly on a window and with the AC cooling the room, a dark window will absorb sunlight and heat up and then that heat will prefer to go into the cool room rather than the hot outside. Maybe the window darkens in the visible but reflects in the IR?

Now or Never
It is good to hear all these developments. I have been watching the developments in solar technologies from my college days, but a big leap is what the industry requires. It was a nice article.

10 years old technology
The Smart Glass is a direct copy of a technology has existed for the past 10 years and has already been applied to prescription eyeglasses; better known as Transition Lenses.

<a class="jive-link-external" href="http://www.transitions.com" target="_newWindow">http://www.transitions.com</a>

Its a chemical coating heated onto a glass or plastic surface. The chemical is sensitive to UV(Ultra Violet) radiation, and turns dark when UV light is applied which makes glass appear to turn dark. For those who don't know, sunlight has UV light in it.
The technology is in its 5th iteration. Each iteration involves making the chemical more absorbant or sensitive to UV light so it turns darker or transparent faster. I don't know anything about if it reflects any light out.

I own 3 pairs of prescription eyeglasses for the past 11 years. They don't work while driving in the car because the windshield absorbs most of the UV light. Too bad the none of the car windows have this technology applied onto the glass. I can image the price for this on a car window is going to be in the thousands when it first comes out. Just a pair of prescription eyeglasses with the coating cost $112 right now.

WHAT IS THE BIG DEAL
FIRST I HAVE BEEN WEARING GLASSES MOST OF MY LIFE, AND FOR MOST OF THAT TIME THEY HAVE DARKEN IN BRIGHT LIGHT AND CLEARED IN DIM LIGHT. SEEMS TO ME THIS TECH HAS BEEN AROUND MORE THEN A LITTLE WHILE AND IS ONLY NOW PRESENTED FOR LARGE SCALE USE FOR THE $$$ POTENTIAL. YOU SHOULD ALL DO YOURSELF A FAVOR AND CHECK OUT THE NEXT TRUE 'GREEN GLASS'. MADE IN CAL. BY XSNX.OB CALLED POWER GLASS. THIS IS ALSO A CHEAP STOCK THAT SHOULD TAKE OFF SHORTLY.
