Evaporating Water Could Power Almost 70% of The US Electrical Grid
It’s not every day scientists say a new kind of renewable energy could satisfy the majority of our power needs, so when they do, it’s worth leaning in close.
In a first-of-its-kind study, researchers have found that energy harvested from the evaporation of water in US lakes and reservoirs could power nearly 70 percent of the nation’s electricity demands, generating a whopping 325 gigawatts of electricity.
Alongside the great strides being made in solar and wind, biophysicist Ozgur Sahin from Columbia University says natural evaporation represents a massive unexplored resource of environmentally clean power generation, just waiting to be tapped.

Dyson to make electric cars by 2020
James Dyson announced Tuesday he was investing £2.0 billion ($2.7 billion, 2.3 billion euro) into developing an electric car by 2020, a new venture for the British inventor of the bagless vacuum cleaner.
The 70-year-old British entrepreneur said work began two and a half years ago on a project which he hopes will help tackle the scourge of air pollution.
“Dyson has begun work on a battery electric vehicle, due to be launched by 2020,” he said in an email to employees, referring to his eponymous company.

3D-Printed Wind Turbine Blades Could Bring ‘Sci-Fi’ Level of Performance
(3Ders.org) The rapid advance of 3D printing technology means that hybrid-material wind turbine blades complete with metal mesh inserts are no longer the stuff of imagination. These energy savers with “sci-fi-level” performance could become reality in as soon as two years. Philip Totaro of Totaro & Associates, “The greatest challenge for wind turbine blade structural and manufacturing engineers is to implement the idealized performance and noise mitigated designs of aerodynamics engineers,” explains Totaro. “Limitations of previous generations of manufacturing technology and the reliance on lower cost materials have limited the type of spar/shear web structures which could be utilized.” But 3D printing could be about to change all that, Totaro says.
