Pitt engineers using membrane distillation to recycle water used in fracking and drilling

Green Car Congress

Engineers at the University of Pittsburgh Swanson School of Engineering are using membrane distillation technology to enable drillers to filter and reuse the produced water in the oil and gas industry, in agriculture, and other beneficial uses. The method is already being tested in Texas, North Dakota, and most recently in New Stanton, Pa.

Researchers demonstrate effective silicon-based thermoelectric generators

Green Car Congress

A University of Texas at Dallas physicist has teamed with Texas Instruments Inc. In a general sense, waste heat is everywhere: the heat your car engine generates, for example. Study co-author Hal Edwards, a TI Fellow at Texas Instruments, designed and supervised fabrication of the prototype devices. —Prof.

Researchers suggest that air quality tests need simplifying to help reduce dangerous emissions

Green Car Congress

Lead author Professor William Stockwell from the University of Texas at El Paso explains that accurate simulations of air pollutants require updated and accurate descriptions of the chemical processes for the changing chemical regimes of the atmosphere and emerging contaminants of concern. Stockwell, Emily Saunders, Wendy S.

Also, there’s a lot of waste. The scholarship is administered on behalf of IEEE Educational Activities and is payable over four years of undergraduate university study. In comparison to launching 2,000 to 5,000 balloons that stay up for just two to three hours, my balloon can stay up in the air for 52 days.”

The EV Transition Explained: Battery Challenges

Cars That Think

The “simplicity” of EVs in comparison to ICE vehicles allows these disruptors to compete from virtually scratch with legacy automakers, not only in the car market itself, but for the material and labor inputs as well. Tesla’s Texas Gigafactory needs some 10,000 workers alone, for example. Furthermore, Dziczek adds, there are.

MIT Researchers Find That Elastic Energy Storage Systems Built With Carbon Nanotubes Could Match Li-ion Battery Energy Densities

Green Car Congress

Densities for steel springs and Li-ion batteries provide a comparison. Any system that requires conversion from mechanical energy to electrical and back again, using a generator and then a motor, will lose some of its energy in the process through friction and other processes that produce waste heat.
