Power system designers commonly face a decision early in a new development over whether to realize the main DC-DC conversion stage as a discrete circuit design with multiple active and passive components, or to use an integrated module, thus implementing the same function with a single part. Traditionally, the pay-off and drawbacks have appeared simple: the module simplifies the board

The Missouri S&T researchers describe the process as a “simple, one-step method to grow nanowires of germanium from an aqueous solution. As a semiconductor material, germanium is superior to silicon, explained Dr. Jay A. Switzer, the Donald L. Castleman/Foundation for Chemical Research Professor of Discovery at Missouri S&T. Germanium was used in the first transistors. It is more expensive to

The giant lithium-ion production facility, designed to supply an increasing market volume of electrical cars with energy storage that Musk intends to establish along with his technology partner Panasonic will fail to achieve a significant effect on battery prices – and it will create a massive overcapacity, says Lux Research analyst Cosmin Laslau. Despite its massive capacity of 35 GWh,

Australian politics has been focused on the future of the country’s Renewable Energy Target for several months now, and it seems that maybe so has the rest of the country. New polling conducted by market research firm Crosby Textor has shown overwhelming support for leaving the Renewable Energy Target (RET) in place. The national study, conducted throughout the month of

We’re nearly four years out since the launch of the first-generation of electric vehicles like the Chevy Volt and Nissan LEAF. In that brief time, the auto industry has learned some hard lessons when it comes to EVs and plug-in hybrids, with upstart automaker Tesla stealing the show late in the game. What can traditional automakers do to recover? Well
