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.

Tesla Cybertruck hits the beach and runs through ocean water

Teslarati

The Tesla Cybertruck was spotted on the beach, driving through ocean water in the Gulf of Mexico just a week from deliveries. Although the truck did not completely enter the water in this instance, we have no idea if the automaker has prepared the pickup to travel through bodies of water. I’d love to hear from you!

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.

Berkeley researchers propose salted biomass as scalable, economical and stable carbon capture and storage solution

Green Car Congress

Researchers from the University of California, Berkeley, are proposing burying salted biomass in a dry environment within an engineered biolandfill as a solution to sequester carbon that has been photosynthetically fixed by cultivated plants. This is measured by “water activity,” a quantity similar to relative humidity. In 1 y, PNAS.

Berkeley Lab leading investigation to quantify and characterize Salton Sea’s geothermal lithium resources

Green Car Congress

The Salton Sea geothermal field in California potentially holds enough lithium to meet all of the US’ domestic battery needs, with even enough left over to export some of it. Normally the cooled fluid would simply be reinjected underground, but the idea is to first extract the lithium from the brine before injecting it back.

2019 Keeling Curve Prize winners include Opus 12; conversion of CO2 into fuels and chemicals

Green Car Congress

The Keeling Curve Prize (KCP) has selected 10 winners for 2019, among them Opus 12 (Berkeley, California) which is developing a device that recycles CO? water and electricity to produce higher-energy carbon-based products and a co-product of pure oxygen. into cost-competitive chemicals and fuels.

Greenius on Patch.com: Lessons Learned on Carbon Neutral City Committee

Creative Greenius

It’s been a rewarding and exhilarating 34 weeks since I first sat down with DiVirgilio, Dency Nelson and Robert Fortunato at the Planet Earth Café to propose that Hermosa Beach become the first municipality in Southern California to go carbon neutral and rebrand itself as the “Green Idea City.&#.
