Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The researchers believe this new type of photoelectrode is not only cheap to produce, but can also be recreated on a larger scale for mass and worldwide use. A promising way of storing solar energy is via chemical fuels, in particular hydrogen as it is considered as a future energy carrier. —Pawar and Tahir. Govinder S.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

This sponsored article is brought to you by COMSOL. 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. This means that storing and distributing energy is as important as its generation.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

Because these “solid oxygen” cathodes are much lighter than conventional lithium-ion battery cathodes, the new design could store as much as double the amount of energy for a given cathode weight, the team says. Overall, the new battery system is “ very scalable, cheap, and much safer ” than lithium-air batteries, Li says. 2016.111.

OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”

Green Car Congress

The state of the art is to use a solar panel to capture the light, and then use a cheap battery to store the energy. Normally, connecting a solar cell to a battery would require the use of four electrodes, the researchers noted. Their hybrid design uses only three. We’ve integrated both functions into one device. —YiYing Wu.

Hacking A Car-Radio Chip Into The Ultimate SDR Receiver

Cars That Think

These modules are cheap—they can generally be found for around US $25. This article appears in the December 2024 print issue as “The Ultimate SDR Receiver.” I soon settled on a configuration consisting of two printed circuit boards connected by ribbon cable.
