Philips shows off its $10 million LED light bulb [LED]

Most people are familiar with the various X Prizes that have been offered for achievements in flight and space travel, but how many know that the US Government has offered an L Prize for energy efficient lighting? The idea is to come up with a 21st century replacement for the 60 Watt light bulb, with the goal of saving 34 Terawatt-hours of power nationwide per year.


Entries must deliver at least 900 Lumens output, with a consumption of less than 10 watts, and must have a lifespan of at least 25,000 hours. There are also rules about light quality and color temperature. The top prize is million.


Philips is the first company to submit an entry, and they showed off their baby Thursday evening at the EcoFocus event in New York.


I think the real question is how much the bulbs will cost to buy. It's hard to convince people to spend big bucks on a bulb, even after you explain the long term savings on their electric bill. I asked if they would sell me the prototype, and they said sure, but it would cost me Million.

Cheap, Printed Solar-Powered LEDs Could Change 1.5 Billion Lives [Solar Power]

Photovoltaic cells printed on sheets aren't news, nor are LEDs and ultrathin lithium batteries. What's news is a combination of the three which can help give light to 1.5 billion people who live in impoverished areas without access to electricity.
Frederik Krebs came up with this combination of solar panels and LED lights which, while definitely a work-in-progress, could bring cheap light to some of the world's poorest regions. I call the lamps a work-in-progress because despite being durable enough to last several years, they run at a mere 1% efficiency. But with the expected final cost of $7 a piece, they're full of life-changing potential, despite that low efficiency.

Some prototypes of the lamps are currently being tested in Zambia. As seen in the picture, the solar panels are left laying flat during the day and then rolled up (and secured with snap-button) into a cone-shaped lamp. I'm definitely looking forward to seeing the results of the prototype tests and a final product, because no one should go without artificially lit nights.

LED Jumper Cables Show How a Little Lateral Thinking Can Make the Mundane Awesome

Jump starting a car is about the easiest semi-mechanical fix that one gets to do. Everyone should have a sit of jumper cables in his/her car: you never know when your battery is going to die and render your car inoperable, or when someone else is going to need help. Doing it by day is extremely easy and just takes a couple of minutes, the trouble is what to do at night; it is a lot harder if you can’t see what you are doing. Having an LED light into the cables keeps you from having to juggle the cables and a flashlight.

Panasonic's LED lightbulb shines for a whopping 19 years

How often do you change lightbulbs? Every few months, maybe? Well, when Panasonic's new LED bulbs hit shelves, change that time frame from months to decades.

Yes, these insanely efficient bulbs keep shining and shining, providing the brightness of a traditional 60-watt bulb. Of course, they won't be cheap, with pricing set at about $40 a bulb in Japan when they hit stores in October. But seeing as they cost a mere $2 to run per year in energy costs and last 19 years, that seems like a good deal in the long run.
