Army Research Lab discovers aluminum nanomaterial rapidly splits water on contact

Green Car Congress

Researchers at the US Army Research Laboratory (ARL) have discovered that a nano-galvanic aluminum-based powder of their design splits water on contact, producing hydrogen and oxygen. The team demonstrated a small radio-controlled tank powered by the powder/water reaction.

RMIT researchers demonstrate working rechargeable proton battery

Green Car Congress

Researchers at Australia’s RMIT University have demonstrated for the first time a working rechargeable “proton battery”. The rechargeable battery is environmentally friendly, and has the potential, with further development, to store more energy than currently-available lithium ion batteries. Earlier post.)

UH team develops new, highly efficient and durable OER catalyst for water splitting

Green Car Congress

Researchers at the University of Houston have developed a catalyst—composed of easily available, low-cost materials and operating far more efficiently than previous catalyst—that can split water into hydrogen and oxygen. Our discovery may lead to a more economic approach for hydrogen production from water electrolysis.

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.

TU Berlin team develops multifunctional catalyst for ORR and OER for fuel cells or rechargeable metal-air batteries

Green Car Congress

One of the challenges in electrocatalysis (be it for solar fuels, fuel cells or rechargeable metal-air batteries) is to find an effective catalyst that will reduce (oxygen reduction reaction, ORR), as well as generate (oxygen evolution reaction, OER), oxygen at moderate temperatures.
