General Motors is the latest automaker reported to be working on solid-state lithium batteries, thanks to a $2 million grant from Uncle Sam.

The money is part of a larger grant to develop more fuel-efficient powertrains, CNET reported. The company is expected to use the rest of the money to develop a lighter-weight, more efficient engine for medium duty trucks, perhaps to replace the company’s 6.2-liter V-8.

Solid-state lithium batteries replace the flammable liquid organic solvents such as ethylene carbonate as an electrolyte in conventional lithium batteries with a solid, ceramic electrolyte that isn’t flammable. That allows engineers to cram more lithium atoms into the battery to give it more energy without increasing volatility, which could lead to lighter, batteries for electric cars with longer ranges.

LIVINGSTON, La. — About a mile and a half from a building so big you can see it from space, every car on the road slows to a crawl. Drivers know to take the 10 mph (16 km/h) speed limit very seriously: That’s because the building houses a massive detector that’s hunting for celestial vibrations at the smallest scale ever attempted. Not surprisingly, it’s sensitive to all earthly vibrations around it, from the rumblings of a passing car to natural disasters on the other side of the globe.

As a result, scientists who work at one of the LIGO (Laser Interferometer Gravitational-Wave Observatory) detectors must go to extraordinary lengths to hunt down and remove all potential sources of noise — slowing down traffic around the detector, monitoring every tiny tremor in the ground, even suspending the equipment from a quadruple pendulum system that minimizes vibrations — all in the effort to create the most “silent” vibrational spot on Earth.

Not only are the batteries eco-friendly, but they are powerful as well. The researchers found a way to make them last longer and provide more electricity batteries by using silicon anodes — an electrode through which the current enters into an electrical device — instead of traditional graphite.

“Today graphite is used as the main commercial material for fabricating the anode electrodes,” Cengiz Ozkan, a professor of mechanical engineering at UC Riverside explained.

“We replaced graphite in the anodes with our new nanosilicon material derived from waste glass bottles,” he continued. “In the half-cell configuration, our batteries demonstrate performance about four times higher compared to graphite anode batteries.” Researchers at the University of California, Riverside’s Bourns College of Engineering used a three-step process to use a discarded glass bottle into lithium-ion batteries.

Summary: The ability to train large scale CNNs directly on your cell phone without sending the data round trip to the cloud is the key to next gen AI applications like real time computer vision and safe self-driving cars. Problem is our current GPU AI chips won’t get us there. But neuromorphic chips look like they will.

A Californian-based start-up has unveiled what it says is the world’s largest computer chip.

The Wafer Scale Engine, designed by Cerebras Systems, is slightly bigger than a standard iPad.

The firm says a single chip can drive complex artificial intelligence (AI) systems in everything from driverless cars to surveillance software.

How far off are we from hopping on and off air taxis as a familiar local mode of transport? Eyes this week were fixed on one company aggressively keeping up its bit to open commercial routes and bring this type of mobility to life.

Volocopter on Wednesday presented its latest air design, dubbed VoloCity. The machine can accommodate two people and hand luggage.

Ben Sampson, Aerospace Testing International, noted that this is actually the fourth electrical take-off and landing aircraft (eVTOL) iteration but “the first that meets the new European Aviation Safety Agency standards.”

It’s not like the one in your car, but a team of physicists at Trinity College Dublin have built what they claim is the world’s smallest engine. The engine is the size of a single calcium ion — about ten billion times smaller than an automobile engine.

Rather than powering your next road trip, the atomic engine could one day be used to lay the foundation for extraordinary, futuristic nanotechnologies.

Here’s how it works: the calcium ion holds an electrical charge, which makes it spin. This angular momentum is then used to convert heat from a laser beam into vibrations.

It’s a lunar lander named ‘Peregrine’, developed by the space robotics company to deliver payloads to the Moon for various companies, governments, universities, non-profits, and individuals for $1.2 million per kilogram. Astrobotic was selected by NASA in May 2019 for a $79.5 million contract to deliver up to 14 payloads to the Moon in 2021, under the agency’s Commercial Lunar Payload Services (CLPS) program.

To date, Astrobotic has signed 16 customers for lunar delivery on that first mission, totaling 28 payloads from 8 nations and comprising resource development, scientific investigation, technology demonstration, exploration, marketing, arts, and entertainment. The vehicle has already passed an industry-standard Preliminary Design Review, and the program will build and test a Structural Test Model, followed by a Critical Design Review, later this year.

Launch is currently slated for June 2021, with a planned landing a month later in Lacus Mortis, a large crater on the near side of the Moo n with payloads such as instruments to conduct new lunar science, pinpoint lander position, measure the lunar radiation environment, assess how lander and astronaut activity affects the Moon, and assist with navigation precision, among other capabilities.
