#At the limit of Moore's law: scientists develop molecule-sized transistors Scientists have created a transistor made up of a single molecule.
Today, United will announce a $30 million investment in Fulcrum Bioenergy, one of the largest makers of aviation biofuels.
Places like big building complexes and shopping centers use heavy amounts of electricity for their giant cooling systems.
You can significantly offset the electricity used for air conditioning, said Shanhui Fan, an expert in photonics at Stanford university who led the development of the mirror. n some situations the computations say you can completely offset the air conditioning.
and can annually save 100mwh of electricity and will be soon available for commercial use r
#Scientists Invented Bionic Leaf to Convert Solar energy into Liquid fuel Aided by a new technique, a team of researchers has found a way of converting solar energy into liquid fuel.
Presently, photovoltaic cells are used to convert solar energy into hydrogen, which is stored then in fuel cells for future use.
Researcher Pamela Silver stated his is a proof of concept that you can have a way of harvesting solar energy and storing it in the form of a liquid fuel.
generating 170,000-megawatt hours of solar power annually that will be pumped into the electrical grids that power AWS cloud datacenters in the eastern and central US.
The Virginia solar farm is part of AWS'larger goal to power its global infrastructure footprint with 100 percent renewable energy.
In January the cloud service provider announced plans for a wind farm in Benton County Indiana, that is expected to produce 500,000-megawatt hours of wind power annually once it's operational in January 2016.
AWS also claims to operate three carbon-neutral regions--US WEST in Oregon, the US Govcloud,
But even with its grand energy commitments, AWS is criticized still highly--mostly by the environmental organization Greenpeace--for its lack of transparency surrounding energy consumption and the way it sources renewable energy.
Beyond the dates set for the solar and wind farms Amazon has committed not publically to a renewable energy deadline.
AWS does say it expects to run its infrastructure on 40 percent renewable power for by the end of 2016.
So far approximately 25 percent of the power consumed within its global datacenters comes from renewable energy sources, according to a recent blog post by AWS cloud chief Jeff Barr.
