Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. These initiatives have largely focused on renewable electric power generation, distribution, and storage.

KU Leuven team creates solar panel that produces hydrogen from moisture in air

Green Car Congress

Bioscience engineers at KU Leuven have created a solar panel that produces hydrogen gas from moisture in the air. If that electric power is used to split the water into hydrogen gas and oxygen, you lose a lot of energy. The KU Leuven bioscience engineers solved this problem by designing a solar panel of 1.6 —Johan Martens.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

In 2001, a team of engineers at a then-obscure R&D company called AC Propulsion quietly began a groundbreaking experiment. It occurred in the wake of the California electricity crisis of 2000 and 2001, when mismanaged deregulation, market manipulation, and environmental catastrophe combined to unhinge the power grid.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The shipping containers, which house a Frankenstein-like assortment of machine parts—motors repurposed from Volvo truck engines, giant tanks of compressed air, huge silos of piping hot sand—are produced by a company called Cheesecake Energy. The compressed air, now cool and easier to store, is housed in a large air tank.
