EPFL solar hydrogen system co-generates heat and oxygen

Green Car Congress

EPFL researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size. This is the first system-level demonstration of solar hydrogen generation. Holmes-Gentle et al. Resources Holmes-Gentle, I., Tembhurne, S.,

Fiat unveils 5 new boxy ‘Panda-inspired’ concept cars

Baua Electric

Fiat just unveiled a new set of Panda-inspired concept cars at the Geneva Motor Show, including a new city car and a pickup truck. The first of the new concepts is a city car (shown above) that is a bit larger than the Panda and available in both ICE and BEV versions – an idea that has been brewing for a while.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

One of the main impediments to harnessing solar energy is storage. Solar batteries work as a short-term solution, but not when it comes to long-term storage or to power, say, an entire city. Solar energy and oil wells might sound like an odd combination, but the principle is similar to how geothermal energy would be harnessed.
