Pilot Project Sends Kelp–and Carbon–to the Seafloor

Cars That Think

Last January, in the waters off Cebu City in the Philippines, researchers first deployed a huge flexible ring seeded with seaweed and spanned by spokelike ropes and tubes. Every nightfall, cranks mounted on a floating platform lower the ring 25 meters below the surface to expose the seaweed to cooler, more nutrient-rich water.

New silicon-hydrogel composite Li-ion anode material shows long cycle life, easy manufacturability

Green Car Congress

A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si. Silicon nanoparticles were dispersed in a solution of phytic acid and aniline in water, followed by the addition of an oxidizer. Click to enlarge. Batteries'
