Inexpensive LEDs

$60 for a light bulb? Sure, it’s an LED-based bulb and will save you real money — and last for ten years.  Using gallium nitride (GaN), they can last for sixty years, but costly to manufacture.  Work by the Cambridge Centre for Gallium Nitride is about to make a real difference. The news, via EE Times:

Cambridge University’s Centre for Gallium Nitride has developed a new way of making GaN which could produce LEDs for a tenth of current prices and may see household lighting bills reduced by up to 75 percent within five years.

Based on current results, GaN LED lights in every home and office could cut the proportion of UK electricity used for lights from 20 percent to five percent. That is equivalent to eight power stations.

The Cambridge researchers have developed a method of growing GaN LEDs on silicon wafers. The lower cost method could enable cheaper mass produced LEDs becoming widely available in the next five years.

Now, here’s the question: who’s willing to make and sell a product that will last for 60 years?

We The Internet

Should Internet access be an entitlemet? I think it should be and some day, it will. The President’s plan to make it available everywhere may be challenged by preferences expressed by those who are supposed to benefit. Maybe they don’t get it — or just don’t care.

Today’s Washington Post has a piece on a report issued by the Pew Internet & American Life Project. Broadband costs more, and that’s holding people back:

According to the survey, 13 percent of non-users said they don’t use the Internet or e-mail because they can’t access broadband. Nine percent of those surveyed said they find e-mail and the Internet too difficult to use, 7 percent said they are too busy or don’t have time, and 4 percent said they don’t have access to a computer.

For those with dial-up Internet access, 35 percent said prices for broadband — which average $34.50 a month — would have to go down for them to upgrade to high-speed cable, fiber-optic, or DSL Internet service, according to the survey.

“The problem with price has to do with competition,” said Andrew Schwartzman, president of public access group Media Access Project. Schwartzman said that users are typically forced to choose between two to three options for high-speed Internet service.

The nonprofit group One Economy has urged lawmakers to include provisions in a stimulus plan that would renovate public housing so that all units in a building would have access to a shared data network, thereby reducing monthly costs per home by several dollars a month.

What if the FCC frees up so-called “white spaces” of radio spectrum and use it for free Internet access? Great idea. Finally, a modern version of the Minitel — only wireless.
