SWISS equips entire Boeing 777-300ER fleet with AeroSHARK riblet films

Green Car Congress

The faster the shark moves through the water, the more efficiently it does so. SWISS will install AeroSHARK on its Boeing 777-300ER fleet successively from mid-2022 during suitable maintenance layovers. They increase buoyancy while generating low-profile vortices that reduce hydrodynamic drag and even add a thrust component.

DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

Projects are encouraged to apply concurrent (as opposed to sequential) design methodologies: control co-design, co-design, and designing for operation and maintenance. It has a low maintenance cost, resulting in a lower cost of energy. HydroMINE is safe for the marine environment, and extremely robust. University of Washington.

IEEE Society Restores Electricity To a Nepali School

Cars That Think

Until recently, the residents of Melamchi, Nepal, cooked meals and heated water for bathing over a wood-burning stove. Although the school had been rebuilt and new power lines had been installed, the electricity wasn’t reliable. Not surprisingly, the leaders said their priorities were access to reliable electricity and hot water.

ABS provides first approval in principle for floating Rankine cycle renewable energy plant

Green Car Congress

Developed by OTEC International (OTI) LLC of Baltimore, Maryland, the approach converts liquid ammonia into gas in a heat exchanger using warm ocean surface water. The ammonia is condensed back into a liquid phase using cold ocean water pumped from 3,000 feet below the water’s surface and the process begins again.

Hydrogenics wins order from E.ON for power-to-hydrogen-gas energy storage project in Germany

Green Car Congress

Power-to-Gas is a novel way to store energy at utility scale, whereby surplus electrical grid power is converted into hydrogen gas. The electrolysis of water into hydrogen whenever surplus electrical power is available is the optimal pathway to increase the renewable content in the energy system mix.
