MIT, Scripps study examines behavior of midwater sediment plumes from deep-sea nodule mining

Green Car Congress

Deep-sea-mining schemes propose sending down tractor-sized vehicles to vacuum up these nodules and send them to the surface, where a ship would clean them and discharge any unwanted sediment back into the ocean (e.g, —Thomas Peacock, professor of mechanical engineering at MIT and co-corresponding author. earlier post ).

MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. Ethanol or methanol would be employed to increase knock resistance. —Daniel Cohn.

A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

MIT researchers advancing development of supercritical water upgrading of heavy crude; lower cost, energy use and CO2

Green Car Congress

Findings by MIT researchers could help advance the commercialization of supercritical water technology for the desulfurization and upgrading of high-sulfur crude oil into high-value, cleaner fuels such as gasoline without using hydrogen—a major change in refining technology that would reduce costs, energy use, and CO 2 emissions.

New self-propelled robotic device pinpoints leaks in pipes more accurately than existing methods

Green Car Congress

Researchers at MIT and King Fahd University of Petroleum and Minerals (KFUPM) in Saudi Arabia have devised a robotic system that can detect leaks in gas, oil and water pipelines at a rapid pace and with high accuracy by sensing a large pressure change at leak locations.
