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

Cars That Think

In 2012, with California in the midst of a severe drought, Schneider, then a mechanical engineering graduate student at Stanford University , once again tossed out a “cool idea.” He imagined a shower head that would sense when the person showering moved out from under the stream of water. You’d waste more water than you saved.

Caltech’s SSPD-1 Is a New Idea for Space-Based Solar

Cars That Think

Several recently published deep-dive analyses commissioned by NASA and the European Space Agency have thrown cold water on the hope that space solar power could affordably generate many gigawatts of clean energy in the near future. Hajimiri: Our idea is to deploy a fleet of these sail-like structures that then all fly in close formation.

Tesla’s Elon Musk shares ideas on how the Cybertruck’s “Boat Mode” can work

Teslarati

Musk’s suggestions were actually practical, making the idea of a seafaring Cybertruck sound quite feasible. Musk also noted that a novel hub design would likely be able to help the Cybertruck generate some thrust in the water. “You’d need an electric propeller mounted on the tow hitch to go faster than a few knots.

Evonik and Siemens Energy commission pilot plant for conversion of CO2 to chemicals

Green Car Congress

Evonik and Siemens Energy commissioned a pilot plant—sponsored by the German Federal Ministry of Education and Research (BMBF)—that uses carbon dioxide and water to produce chemicals. For the idea of artificial photosynthesis, which is behind the Rheticus experimental facility, the researchers took nature as a model.

UMD/USARL team develops “water-in-salt” electrolyte enabling high-voltage aqueous Li-ion chemistries

Green Car Congress

A common practice to suppress hydrogen evolution in aqueous electrochemistry is to adjust the alkalinity, so that the water reduction potential shifts downward to allow the use of anode materials otherwise prohibited under neutral or acidic conditions. What’s most important about our work is the breakthrough made at the fundamental level.

Purdue and Duke Energy to explore potential for SMR nuclear power source for campus

Green Car Congress

Innovation and new ideas are at the core of what we do at Purdue, and that includes searching for ways to minimize the use of fossil fuels while still providing carbon-free, reliable, and affordable energy. SMRs are revolutionary in part because of their modular nature. —Purdue President Mitch Daniels.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. The idea was to understand the changes in the molecular structure of molybdenum disulfide, so that it can be a better catalyst for hydrogen production: closer to platinum in efficiency, but earth-abundant and cheap.
