Energy Strategy 2050: the potential of millions of Swiss rooftops

— Five million rooftops in Switzerland – more than half of the nationwide total – are suitable for generating power. A review of two solar photovoltaic development strategies has shown that combining the two approaches could cause over two-thirds of Swiss towns and cities to become energy self-sufficient.

Turning glass into a ‘transparent' light-energy harvester

— EPFL physicists propose a novel way to create photoconductive circuits, where the circuit is directly patterned onto a glass surface with femtosecond laser light. The new technology may one day be useful for harvesting energy, while remaining transparent to light and using a single material.

New technology can collect CO2 from a truck's exhaust pipe

— EPFL spin-off Qaptis has developed a system that can cut freight trucks’ carbon emissions by up to 90%. The company just installed a prototype of its technology at a freight carrier based in Tolochenaz in order to conduct pilot tests locally.


Ultrathin films achieve record hydrogen separation

— Scientists at EPFL have synthesized the first ever metal-organic frameworks membrane with thickness of just one unit cell. The ultrathin film yields record-high separation performance of hydrogen–nitrogen.
