Danish energy gets super-sized: meet the world's largest wind turbine Wired.co.uk
| Wired.co.uk | - |
When it comes to wind turbines, size matters. Besides air density and wind speed, the most important factor affecting energy yield is the rotor's swept area, where wind flows over the rotor blades. That's why Siemens has built the B75, a record ...

All that's lacking - your Heart. 8,000 times our current power requirements - amount of sun reaching earth. ExtremeTech
| ExtremeTech | - |
Solar power has the potential to solve all of humankind's energy problems. The amount of solar
energy that reaches the surface of the Earth, per year, is somewhere in
the region of 8,000 times higher than our current power requirements.

YOUR Will, all we lack: MIT startup makes transparent solar panel that will allow your smartphone to ... ExtremeTech
| ExtremeTech | - |
Transparent solar panels - think about it for a moment: Sheets of transparent glass or plastic film that also generate electricity.
Battery Storage Technology Advances. All we lack is Your will.
Lithium air battery gives IBM hope of power without fires.
International Business Machines Corp. plans to
release a prototype next year of an alternative battery technology it
calls “lithium air” that would mark a big step forward by packing in
more storage capacity.

All that's lacking is Your Body in the Way: Next-Generation Lithium-Ion Battery Designed, Should Hit Market Within 2-3 Years
Posted: 19 Feb 2013 03:00 AM PST
Next-generation lithium-ion
batteries that hold more than 3 times the charge that current batteries
do and can recharge in around 10 minutes are now within reach. The new
design, created by researchers at the University of Southern California
(USC), may be commercially available within only 2-3 years according to
those involved.
Chinese Companies Projected To Make Solar Panels for 42 Cents Per Watt In 2015

Future
cost drops from Chinese crystalline silicon solar producers will not be
as steep as recent years, but they will still be significant.
Tough Little Bug Smashes Down Wall Between Us And Sustainable Biofuel
Posted: 15 Feb 2013 05:37 AM PST
The biofuel fuel vs. food
debate has really been getting a workout this year, especially in the
U.S. where a historic, devastating drought has put the squeeze on corn
ethanol. More sustainable biofuel crops like perennial grasses and shrub
willow are under development, but the sugars in plants like these are
locked away behind tough, woody cell walls, and getting at them can be a
costly process. Now researchers at Brown University have found a bacteria called Streptomyces, which could be deployed as a microscopic “biorefinery” to get the job done.
Biofuel from Bacteria
With soft biomass such as cow
manure, a microbe-based biofuel process can be relatively quick and
inexpensive, and it is already being deployed commercially with a push
from the Department of Agriculture’s AgStar program.

Envision Plans To Install 2300 Rotating Solar Tree Car Shelters In South Carolina. CleanTechnica
| CleanTechnica | - |
According
to Inhabitat, roughly 160 billion square feet of land have been paved
and used just as parking lots for cars. Envision plans to use some of
this space to accommodate solar panels structures called solar tree car shelters. Is this wasting even ...

NASA to launch new earth-observing satellite.
NASA to launch new earth-observing satellite.
If the weather holds, NASA will launch its
newest Earth-observing satellite from Vandenberg Air Force Base in
southern California late Monday morning. The satellite can monitor
changes in the earth's surface, including those linked to climate
change.

The future of energy: Batteries included? Produce the right battery at the right price, many engineers think, and you could make the internal-combustion engine redundant and usher in a world in which free fuel, in the form of wind and solar energy, was the norm. That really would be a revolution. Economist

10 Huge Lessons We've Learned From Solar Power Success In Germany. CleanTechnica
| CleanTechnica | - |
Solar panels are a global commodity. Their price is essentially the same all around the world. However, the “soft costs” of a solar power system can vary tremendously. As noted back in June 2012, German solar installations cost a little more than half ...

A Cleaner Way to Use Coal Kevin Bullis. MIT Technology Review
| MIT Technology Review | - |
In ordinary coal plants, coal is pulverized to make a fine powder and then burned in air to produce steam to drive turbines.
Nanoantenna Solar Cell Efficiency Can Blow Silicon Out Of The Water. CleanTechnica
| CleanTechnica | - |
Today, conventional silicon solar cells are 10% to 20% efficient (this means that they generate 100 watts to 200 watts per square metre of cells, respectively).

A Manmade Island to Store Wind Energy. MIT Technology Review
| MIT Technology Review | - |
When the wind
farm produces excess energy for the local electricity grid, such as
off-peak times in the overnight hours, the island will store the energy
and release it later during peak times.
Novel Designs Are Taking Wind Power to the Next Level Kevin Bullis MIT Technology Review
| MIT Technology Review | - |
The technology is part of a trend that's made wind power almost as cheap as fossil fuels. In 1991, wind power cost 15 cents per kilowatt hour.
