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.

Will autonomous vehicles increase efficiency and make us safer?

This week's Question: Google has been testing its autonomous cars on public roads. The search giant's fleet of robotic Toyota Priuses has now logged more than 190,000 miles, driving in city traffic, busy highways, and mountainous roads, with only occasional human intervention. The Google team asserts that the smarter vehicles could help make transportation safer and more efficient. For example, cars could drive closer to each other, making better use of the empty space on roads, and also form speedy convoys on freeways. The vehicles would also react faster than humans to avoid accidents. Do you agree? Will autonomous vehicles increase efficiency and make us safer?

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.

Technology Reduces Production Costs of Lithium-ion Cells

A development by engineers of Germany's Karlsruhe Institute of Technology (KIT) is inspired by nature. To fill the porous electrodes of lithium-ion batteries more rapidly with liquid electrolyte, they use a physicochemical effect that also provides water transport in trees. The new process increases the throughput of battery production and reduces investment costs.

Are you alarmed by the information collected by Verizon and other wireless carriers?

This week's Question: Verizon, the U.S. largest wireless carrier, recently announced that it will "create business and marketing reports" and "make the mobile ads you see more relevant," based on the information the company collects pertaining to a user's Web surfing destinations, applications, and location information. Verizon stated that none of the information used or shared will be personally identifiable, and those customers who don't want their information shared can choose to opt-out of the feature. Although Verizon is not the only wireless carrier to adopt this type of data-AT&T and Sprint have similar processes, for example-many skeptics cite the privacy implications of mobile advertising. What do you think? Are you alarmed by the information collected by Verizon and other wireless carriers?

Record-Breaking Solar Cells

Developed by Singapore's Nanyang Technological University (NTU) and A*STAR Institute of Microelectronics (IME), new thin-film silicon solar cells are designed to be made from cheaper, low-grade silicon. The nano-structured solar cells can produce a current of 34.3mA/cm2 – a world record for a silicon solar cell of its kind.
