A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. How about mostly sulfur? A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for
The amount of time it takes to recharge lithium-ion batteries has been a major impediment to consumer acceptance of electric vehicles. But a host of companies and researchers are working intensively to develop a battery that can recharge in 10 minutes and power a car for hundreds of miles.
Often described as the next evolutionary leap in battery systems, solid state batteries substitute solid electrolyte films for liquid electrolytes, thus eliminating the need for cooling devices and supporting materials and making the battery more stable and efficient. Theoretically, they have the potential to cut both the size and the price of batteries in half.
A semiconductor is a material with electrical conductivity intermediate in magnitude between that of a conductor and an insulator. Semiconductor materials are the foundation of modern electronics, including radio, computers, telephones, and many other devices. Such devices include transistors and digital and analog integrated circuits. Transition metal oxides also
Below is a wonderful video that explains the multiple drivetrains at work in the Chevy Volt. A couple of immediate impressions:
1) No wonder the price on this sucker is $41K, with all that going on. The bill of materials (costs of the individual components) must be enough to choke a horse. And the non-recurring engineering costs must
About one fifth of the world’s population lacks access to electricity. It is one of biggest economic obstacles for people in developing countries, but one that could mean opportunities for a clean energy beginning with alternative energy.
Electric cars may present different hazards than conventional design. Recent crash tests as well as one report of a battery fire suggest that the present car design may have to be improved. Crash tests have been carried out in the well known Euro NCAP testing center on the Volt and the Renault Fluence EV that gives
Renewable energy such as solar has a basic problem: No sun , no power. In order to make it more usable the Power must be stored for off peak use when the sun does not shine. Batteries though die when repeatedly recharged. Stanford researchers have developed part of better battery, a new electrode
Duke Energy is a large energy company with headquarters in Charlotte, North Carolina. Duke Energy has assets in the United States as well as Canada and Latin America. This energy company has been providing businesses and residents with gas and electric services that are reliable, clean, as well as
In the past ten years, environmentally friendly cars have become a fixture in advertising. First came the Prius. Then BMW claimed its electric batteries boost performance, great for boosting the entire BMW brand. Chevy Volt, an electric hybrid, hypes range, innovation and American values, trying to minimize its
The U.S. Air Force recently announced that its Los Angeles base would be the first federal facility to replace 100 percent of its general purpose fleet with electric vehicles.
This switch will mean all 40 vehicles owned or leased by the base, including passenger sedans, two-ton
Researchers at MIT have designed a device the size of a U.S. quarter that harvests energy from low-frequency vibrations, such as those that might be felt along a pipeline or bridge. The tiny energy harvester — known technically as a microelectromechanical system, or MEMS — picks up a wider range of
Japanese researchers are developing a new system that they say could ultimately power electric vehicles (EVs) for travel across “unlimited” distances without the hindrance of heavy batteries.
While based on railway infrastructure in which individual cars are powered through overhead wires,
