Harvesting Electricity: Triboelectric Generators Capture Wasted Power

submitted by: nsf

With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs--with no batteries or power cord. A professor at the Georgia Institute of Technology, Wang is using what’s technically known as the triboelectric effect to create surprising amounts of electric power by rubbing or touching two different materials together.

Approaches to Evaluating and Improving Lithium-Ion Battery Safety

submitted by: RASEIBoulder
As lithium-ion battery technologies mature, the size and energy of these systems continues to increase for emerging applications in transportation, grid storage, military use and aerospace. In fact, broadening the application space for lithium-ion batteries from the consumer electronics industries to these emerging markets increases their size from 1-50 Wh batteries for smart phones and laptops to >50 kWh for electric vehicles (EVs) and MWh scale for utility storage systems. As these...

Excitons and Plasmons in Nanoscale Systems

submitted by: RASEIBoulder
Summary: Due to growing populace and standard of living, many terawatts of energy will be needed in the near future. The sun is the largest source of carbon-neutral and renewable energy that we have available and it is the only source that can provide terawatts of energy without depleting rapidly or causing major environmental and climate concerns. To fulfill this role, revolutionary approaches to solar energy conversion are needed that provide energy at very high efficiency at very low...
