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

Green Car Congress

The midwater plume comprises two stages: (i) the dynamic plume, in which the sediment-laden discharge water rapidly descends and dilutes to a neutral buoyancy depth, and (ii) the subsequent ambient plume that is advected by the ocean current and subject to background turbulence and settling. Earlier post.). —Thomas Peacock.

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 engineers develop process that can treat produced water from gas wells at relatively low cost

Green Car Congress

A new desalination process developed by engineers at MIT could treat produced water—deep water, often heavily laden with salts and minerals—from natural gas wells at relatively low cost. The research is the work of a team including MIT postdoc Prakash Narayan, mechanical engineering professor John H.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires.

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.

MIT Researchers Identify New Low-Cost Water-Splitting Catalyst

Green Car Congress

Daniel Nocera and his associates have found another formulation, based on inexpensive and widely available materials, that can efficiently catalyze the splitting of water molecules using electricity. Earlier post.). Earlier post.). Materials for the new catalyst are even more abundant and inexpensive than those required for the first.
