Study finds anthropogenic PM and dust undercutting global solar energy production

Green Car Congress

According to a new study led by a team at Duke University, airborne particulate matter and dust are cutting solar photovoltaic energy output by more than 25% in certain parts of the world, with roughly equal contributions from ambient PM and PM deposited on photovoltaic surfaces.

TUM, partners to present electric aCar prototype at IAA; transport for sub-Saharan Africa

Green Car Congress

Researchers at the Technical University of Munich (TUM) and partners will present their new prototype of an electric four-wheel drive utility vehicle designed for Africa—the aCar — at the International Motor Show (IAA) in Frankfurt next month. Solar modules mounted on the roof of the aCar gather energy throughout the day.

Generating Power on Earth From the Coldness of Deep Space

Cars That Think

But we have demonstrated that by directly using power generated by the cold universe, we can chill water to cool buildings by as much as 5 ºC during the day without electricity and light the night without wires or batteries. As the technology improves, we see it enabling solar panels that work at night as well as day, powering remote sensors.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet. Little is known about how, or whether, solar geoengineering might work and how the particles would react and move in the stratosphere. cancel the launch. “The

IU team creates efficient nanographene-Re electro- and photo-catalyst for efficient reduction of CO2 to CO

Green Car Congress

Researchers at Indiana University Bloomington have synthesized a nanographene–Re (Rhenium) complex that functions as an efficient electrocatalyst and photocatalyst for the selective reduction of CO 2 to CO for subsequent conversion to fuels. The complex can selectively electrocatalyze CO 2 reduction to CO in tetrahydrofuran at −0.48

Study finds modifying urban form may be a strategy to reduce air pollution

Green Car Congress

Based on their findings in a new study, researchers from the University of Washington and the University of Minnesota suggest that modifying urban form—as a means of affecting motor vehicle usage—may be a strategy to mitigate urban air pollution.
