- New World Record Achieved in Solar Cell Technology - New
Solar Cell Breaks the “40 Percent Efficient” Sunlight-to-Electricity Barrier.
U.S. Department of Energy (DOE) Assistant Secretary for Energy
Efficiency and Renewable Energy Alexander Karsner today announced that
with DOE funding, a concentrator solar cell produced by
Boeing-Spectrolab has recently achieved a world-record conversion
efficiency of 40.7 percent, establishing a new milestone in
sunlight-to-electricity performance, says this Dec 2006 report from US

- High Efficiency Solar Cell breakthrough - February, 2006
- In a scientific breakthrough, a team of South African scientists has
developed a revolutionary new, highly efficient solar power technology
that will enable homes to obtain all their electricity from the sun. The
South African solar panels consist of a thin layer of a unique metal
alloy that converts light into energy. The photo-responsive alloy can
operate on virtually all flexible surfaces, which means it could in
future find a host of other applications. Alberts said the new panels
are approximately five microns thick, compared to older silicon panels
which are 350 microns thick. Read more from IOL
- As Much Hot Water As Your Need Or The Sun In Trap - A
unique solar collector was developed by specialists of the Moscow “ALTEN”
company. The collector not only manages to entrap the heat of solar
beams falling on its surface, but also to utilize it to a great extent
for direct purpose – for water heating. To increase efficiency of
absorption of solar energy and to reduce loss of heat, a special
selective multi-layer coating based on titanium carbide is used. The
coating allows to entrap solar energy in the visible and near infra-red
spectral region where more than 90 percent of solar energy is
concentrated. Read more from this Feb 2006 PhysOrg report
- Solar cell breakthrough: 40% efficiency achieved - Dec,
2006 - Researchers at Boeing-Spectrolab have just succeeded in building
a multi-junction solar cell that achieves an incredible 40.7% efficiency
- about twice that of the reigning champ in this space. Multi-junction
cells are cells composed of several layers, with each slice capturing
only a portion of the solar spectrum. More from this End

- Emerson Introduces Breakthrough Air-Conditioning
Technology to Meet 2006 Federal Efficiency Standard - Business Wire, Feb
2005 - Emerson Climate Technologies introduced the next generation of
its industry-leading Copeland Scroll(TM) compressors designed to more
efficiently and quietly power residential and light-commercial central
air conditioning systems. The new Copeland Scroll manufacturing platform
includes a full product line of 1.5 to 5 horsepower compressors,
available in R-410A and R-22 refrigerants, and motor voltages for both
residential and light commercial applications. More info from this Find

- Accidental invention of white LEDs could light up the
future - An accidental invention by a graduate student at Vanderbilt
University, when he was trying to make quantum dots (Quantum dots are
easily excited crystals generally just a few nanometers big &
contain anywhere from 100 to 1,000 electrons), could lead to mass usage
of LEDs for lighting, offering a cheaper, longer-lasting alternative to
the traditional light bulb. When you shine a light on quantum dots or
apply electricity to them, they react by producing their own light,
normally a bright, vibrant color. But when Bowers shined a laser on his
batch of dots, a white light appeared. The new device gives off a warm,
yellowish-white light that shines twice as bright and lasts 50 times
longer than the standard 60 watt light bulb. This work is published
online in the Oct. 18 edition of the Journal of the American Chemical
Society. The Department of Energy estimates LED lighting could reduce
U.S. energy consumption for lighting by 29 percent by 2025. Read full report from MSNBC

About Oilgae - Oilgae - Oil & Biodiesel from Algae
has a focus on biodiesel production from algae while also discussing
alternative energy in general. Algae present an exciting possibility as a
feedstock for biodiesel, and when you realise that oil was originally
formed from algae - among others - you think "Hey! Why not oil
again from algae!"
To facilitate exploration of oil production from algae as well as exploration
of other alternative energy avenues, Oilgae provides web links, directory,
and related resources for algae-based biofuels / biodiesel along with inputs
on new inventions, discoveries & breakthroughs in other alternative
energy domains such as solar, wind, nuclear, hydro, geothermal, hydrogen
& fuel cells, gravitational, geothemal, human-powered, ocean & wave /
tidal energy.
