New Super-Efficient LED Light

Posted on Thursday, January 29, 2009 posted by posted by Mak @ 8:30 PM

LED light bulbs are already more efficient than our average bulb, but researchers at the Renssalaer Polytechnic Institute have developed a new kind of LED that exhibits both improved energy efficiency and lighting performance. The researchers‘ polarization-matching LED shows an 18 percent increase in light output and a 22 percent increase in wall plug efficiency (the amount of electricity that the LED converts into light).Renssalaer’s LED is more powerful thanks to a reduction in “efficiency droop”, which makes LEDs most efficient when receiving low-density electrical currents and least efficient when higher density electrical currents are received.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
