MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. These structures would serve both as anchors to moor the floating turbines and as a means of storing the energy they produce. Earlier post.).

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. (B) MS signal and SFE values for a wireless configuration. Reece et al. Click to enlarge.

ExxonMobil, MIT and Synthetic Genomics team publishes results of LCA on algal biofuels; potential for large reductions in GHG

Green Car Congress

Algae have the potential to produce large volumes of fuel per unit area of production on marginal lands using saline water unsuitable for food crops. Thus, algal biofuels could expand transportation energy supplies, without significantly displacing land and water resources that would otherwise have been used for food production.

National University of Singapore researchers devise membrane-based supercapacitors; possible new route to high-performance supercapacitive energy storage

Green Car Congress

When sandwiched between and charged by two metal plates, the membrane can store charge at 0.2 In the PEDT:PSSH network presented.the hydrophobic PEDT forms a water-insoluble framework, while the superhydrophilic PSSH provides SO 3 groups for hydration channel formation throughout the framework. —Xie et al. —Xian Ning Xie.

Virtual Reality Helps Students Improve Their Math Literacy

Cars That Think

In the chemistry module on acids and bases, for example, students are shown a computer-generated version of a wastewater-treatment plant in Baltimore, and they try to make chemically contaminated water safe to drink. STEM at the root Ganguly says she was inspired to help reform STEM education when she was a graduate student at MIT.

Study finds climate-influencing cirrus clouds form around mineral dust and metallic aerosols; little evidence of black carbon

Green Car Congress

An interdisciplinary team from MIT, the National Oceanic and Atmospheric Administration (NOAA), and elsewhere has identified the major particles upon which cirrus clouds form. Formation of cirrus clouds depends upon the availability of ice nuclei to begin condensation of atmospheric water vapor.
