Electronically Assisted Astronomy on the Cheap

Cars That Think

That required a solar filter, of course. This article appears in the May 2024 print issue as “Electronically Assisted Astronomy.” Stacking software takes a series of images of the sky, compensates for the motion of the stars, and combines the images to simulate long exposures without blurring.

PA Turnpike considers solar-powered EV charging stations

Teslarati

The Pennsylvania Turnpike is attempting to power its EV charging stations with solar power facilities along the highway. With cheap energy generation, one high cost of EV charging can be removed, assisting organizations in achieving profitability. The Turnpike has already constructed its first solar facility in Jeanette, capable of 1.3

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. Sand is efficient, nontoxic, portable, and cheap!”. “We

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

Green Car Congress

The basic concept of the integrated solar battery is to use the contribution of the photovoltage to reduce greatly the charging overpotential caused by the difficulty in efficiently electrochemically decomposing lithium peroxide (Li 2 O 2 ), the discharge product formed on the oxygen electrode. —Yu et al. Photo-assisted charging. (a)

Why is Hydroelectricity So Green, and Yet Unfashionable?

Cars That Think

There is no end of gushing about China’s cheap solar panels—but when was the last time you saw a paean to hydroelectricity? Instead, that pure status is now reserved above all for wind and solar. The manufacture of solar panels involves the environmental costs from mining, waste disposal, and carbon emissions.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The idea was to understand the changes in the molecular structure of molybdenum disulfide, so that it can be a better catalyst for hydrogen production: closer to platinum in efficiency, but earth-abundant and cheap. Molly is dirt cheap and abundant. —Stan Chou. People want a non-platinum catalyst. Luk, Bryan Kaehr & C.
