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.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. A study by Mark Z.

Arizona State Students Develop a Solar-Powered Air Filtration System

Cars That Think

A team of students from the Fulton Schools of Engineering at Arizona State University is helping to improve the air quality for nomadic communities in Mongolia. A drought in Mongolia has led to food shortages, prompting the nomads to migrate to the Ger district in the capital of Ulaanbaatar, one of the world’s most polluted cities.

Wuhan team develops new electrochemical cell for efficient, pollution-free extraction of lithium from salt lake brines

Green Car Congress

Researchers at Wuhan University in China have developed a new electrochemical cell, PANI/Li x Mn 2 O 4 , for selective recovery of Li + ions from brine water with high impurity cations (K + , Na + , Mg 2+ , etc). This method avoids using additional chemicals, offering a high efficiency, pollution?free Zhao et al. Zhao, A. , and Cao, Y.
