This Idea Wasn't All Wet: The Sensing Water-Saving Shower Head Debuts

Cars That Think

He imagined a shower head that would sense when the person showering moved out from under the stream of water. The shower head would then automatically turn the water off, turning it back on again when the person moved back into range. With such a device, he thought, people could enjoy a long shower without wasting water.

Libertine awarded $3.6M to develop renewable-fueled free-piston-engine range extenders for battery electric trucks

Green Car Congress

This technology enables improved cold start performance using wet or ‘hydrous’ bioethanol fuel, a blend of 90% bioethanol and 10% water (E90W10). Libertine says that its intelliGEN control technology solves the free-piston motion challenge, optimizing combustion conditions from the first ignition cycle.

UNIST team boosts performance of perovskite catalyst for metal-air batteries & fuel cells using polypyrrole

Green Car Congress

Korea’s UNIST, with colleagues from Northwestern University, have successfully developed a new way to increase the activity of perovskite oxide catalysts for the oxygen reduction reaction (ORR) and/or the oxygen evolution reaction (OER) in rechargeable metal-air batteries and fuel cells simply by adding the conductive polymer polypyrrole.

Niagara Falls Maid of the Mist vessels going battery-electric; ABB power and propulsion

Green Car Congress

Cuomo announced that Maid of the Mist, which has been navigating the waters of the Lower Niagara River since 1846, will launch later this year two new all-electric, zero-emission passenger vessels constructed in the United States. The color scheme is environmentally-friendly green combined with the blue of the water.

Electric or hydrogen cars – which makes more sense for NZ?

Drive Electric

Hydrogen fuel cell vehicles (FCVs) use Hydrogen to generate electricity, producing only water vapour as a byproduct. This electricity is then used to propel the vehicle’s electric motor and recharge its battery. Hydrogen fuel cells convert hydrogen gas into electricity, the only byproduct being water vapour.
