First all-electric car-sharing program in North America

ECOtality, Inc., a leader in clean electric transportation and storage technologies, announced recently a partnership with car2go N.A. LLC, a subsidiary of Daimler North America Corporation, to provide electric vehicle charging infrastructure to support the first 100-percent electric car sharing program in North America. With plans for approximately 300 smart for two electric drive vehicles, the program in San Diego represents the largest fleet of EVs in the United States.

Interview with IPS's Director of Applications Engineering, Joe Keating

Mr. Joe Keating, director, applications engineering manager with Infinite Power Solutions, Inc. (IPS) talked to IDTechEx technology analyst Harry Zervos about the company's developments and its positioning within the emerging energy harvesting sector.

New solar technology could break photovoltaic limits

Photovoltaic (PV) efficiency is a significant problem for today's commercial solar panels, which can collect only a theoretical maximum of about 30 percent of available light. Now, a team that includes a University of Missouri engineer is developing a flexible solar film that can theoretically capture more than 90 percent of available light. Prototypes could be produced within the next five years.

Best for batteries: Not too hot, not too cold

With average U.S. gasoline prices approaching $4 a gallon, drivers and automakers are thinking electric. Previously steered in this direction by concerns about pollution and dependence on foreign oil, consumer interest in electric-drive cars continues to surge. But before Americans are able to flip the switch from gasoline to electricity, automakers need batteries for the next generation of electric vehicles that can deliver the range, performance, reliability and safety drivers expect.

Energy harvesters convert waste heat into electricity

The high-efficiency thermal waste heat energy converter actively cools electronic devices, photovoltaic cells, computers and large waste heat-producing systems while generating electricity.

Greatly enhanced supercapacitor

Researchers at The University of Texas at Austin's Cockrell School of Engineering have created a new porous, three-dimensional carbon that can be used as a greatly enhanced supercapacitor, holding promise for energy storage in everything from energy grids and electric cars to consumer electronics.
