Researchers Striving to Cut Waste When Slicing Silicon

A filigree wire is standardly used to slice silicon blocks (ingots) into paper-thin wafers for solar cells. This wire can cut through the ingot at a speed of up to 60 km/h. Several hundred kilometers long, the wire is arranged in such a way that the ingot is sliced into hundreds of wafers...

Reinventing the Tuktuk

In large cities across Asia, auto rickshaws (tuktuks) are one of the most important means of transportation. These tuktuks produce considerable CO2 emissions and air pollution, and their drivers are underpaid. Students participating in the Hybrid Auto Rickshaw project sought to cut CO2 emissions by 40%, while improving the...
