Affordable Solar Option for Power Plants

Solar thermal power plants - which use high temperatures and pressure generated by sunlight to produce turbine movement - are an environmentally-friendly alternative to standard power plants. But this can be expensive, especially when it comes to equipment made from expensive metals and the solar high-accuracy concentrator technology used to harvest solar energy.

Composite Metamaterial for Solar Tech

A Northwestern University research team has developed a new material that absorbs a wide range of wavelengths and could lead to more efficient and less expensive solar technology. The researchers used two unconventional materials – metal and silicon oxide – to create thin but complex, trapezoid-shaped metal gratings on the nanoscale that can trap a wider range of visible light.

Ongoing Power Performance Research to Advance Electromobility

The AutoTram® is as long as a streetcar and as maneuverable as a bus. It doesn’t need rails or overhead lines because it rolls on rubber tires and simply follows white lines on the street. In “Fraunhofer’s System Research for Electromobility,” the AutoTram® was used as an experimental platform. It was a component of the research collaboration of more than 30 of Germany's Fraunhofer institutes.

Improving the Physics of Grocery Store Display Cases to Save Energy

Designing grocery display cases has a lot in common with aeronautical engineering. Refrigerated display cases shoot jets of air across their front openings, creating an invisible shield that aims to keep cold air in and warm air out. Current technology does this with limited success. Engineers at the University of Washington and Kettering University have found that tweaking the physics can reduce energy by as much as 15 percent.
