Unlikely City Claims Nation’s Largest Electric Car Share

Far from high-tech Silicon Valley or hipster Austin, Texas, the largest all-electric car-sharing service is being built.

If your second guess is Portland or Brooklyn, keep guessing…and moving inland. Indianapolis, the nation's twelfth largest city, will install 1,200 charging stations at about 200 locations to support 500 electric vehicles. The project is expected to be up and running within a year.

Indianapolis is hardly a hotbed of alternative transportation. It does have a bus system, but “we have one of the worst ranked bus services in the country for a city our size,” said Paul Mitchell, president and CEO of Energy Systems Network (ESN), a nonprofit clean technology initiative that is working on the EV project in Indianapolis. It was not one of the twenty-one metro areas chosen by the Department of Energy as part of the EV Project.

Dinosaur-Inspired Designs Make Wind Turbines More Aerodynamic

"In the grand scheme of things, we're still in the early stages of wind power generation, but even so, there are still many, many wind turbines already installed and generating power. When new technological advances come along like new turbine designs or tweaks to the blades or motors that can increase power generation, replacing entire wind turbines would be very costly. Because of that, Siemens has developed a set of wind turbine blade attachments that increase power generation without having to fully replace any part of the turbine.

The coolest part of these add-ons? They're inspired by dinosaurs.

SASE to tap wind energy in snow-bound areas

To cater to the energy requirements of the armed forces in remote snow-bound areas, the Defence Research and Development Organisation (DRDO) is exploring the potential of tapping wind power to generate energy.

While the Himalayan ridges are known for their high wind potential, accumulation of heavy snow and ice in that region is a critical factor that adversely affects sensitive structures and also jams moving parts in turbines.

New Flow Battery Propel Solar and Wind Power to the Grid

A major obstacle to the widespread use of solar and wind power to supply the grid is the problem of storing the energy produced at a low enough cost. Energy generated by the wind and the sun is subject to unpredictable fluctuations. Until now, the cost of batteries large enough to smooth out these swings in production has made the technology relatively uneconomic.
