Researchers from MIT and Harvard University have developed a material that can absorb the sun’s heat and store that energy in chemical form, ready to be released again on demand. A paper describing the new process is published in the journal Nature Chemistry.

U.S. Navy’s New Jet Fuel: Seawater?
Navy researchers at the U.S. Naval Research Laboratory (NRL), Materials Science and Technology Division, demonstrate proof-of-concept of novel NRL technologies developed for the recovery of carbon dioxide (CO2) and hydrogen (H2) from seawater and conversion to a liquid hydrocarbon fuel.
Driver with more than 220 convictions walks free from court
A reckless driver who has flouted his driving ban for the 44th time and has more than 220 driving convictions to his name has walked free from court, with campaigners saying he has made a mockery of the justice system.
2015 Chevrolet Corvette Z06 Convertible unveiled ahead of New York
Chevrolet showed us the all-new supercharged 2015 Corvette Z06 coupe earlier this year in Detroit with at least 625bhp. It’s an impressive vehicle scheduled to go on sale early next year.
Hyundai researchers report improved Li-sulfur battery performance
Researchers from Hyundai have found that the use of a new sulfone-based electrolyte greatly improved the capacity and reversible capacity retention of a Li-sulfur battery compared to the performance of ether-based electrolytes.
In a paper presented at the SAE 2104 World Congress in Detroit, they reported that use of the sulfone-based electrolyte increased capacity by 52.1% to 715 mAh/g and capacity retention by 63.1% to 72.6%.Lithium-sulfur systems are of great interest as a “beyond Li-ion” solution with increased energy densities that would enable much greater electric vehicle range. The Li/S system has a high theoretical specific energy of 2600 Wh kg-1; however, rapid fading of charge capacity is a well-known issue.
