Tesla launches new AMD chip and 12v Li-ion battery in 2022 Model 3 Model Y vehicles

Posted by in categories: computing, sustainability, transportation

Tesla has introduced the new AMD Ryzen chip and 12v Li-ion battery in 2022 Model 3 Model Y vehicles.

Earlier this month, we reported on a bunch of new features and changes coming to the Tesla Model 3 and Model Y that leaked through a test program in Europe.

Amongst many things, the leak revealed that new Model 3 and Model Y vehicles coming to Europe, which are made in China, would come with the new AMD Ryzen chip that is powering the media computer in the new Model S and Model X and the Model Y Performance made in China. Also, the lead-acid 12v battery will change to a Li-ion battery system.

Greenworks 48V 17-inch battery-powered mower combo now $246, more in New Green Deals

Posted by in categories: sustainability, transportation

If you missed out on Black Friday electric mower deals, then you’re in luck. The Greenworks 48V 17-inch brushless cordless electric mower is back at its third-best price that we’ve seen all-time at $246. Not only does this bundle include the gas-and oil-free mower, but also two 4Ah 24V batteries and a 24V drill/driver. You’ll also find discounts on electric lawn mowers and much more below, as well. We also have a wide selection of Tesla, Greenworks, and other e-bike discounts in today’s New Green Deals, so you won’t want to miss that either.

Head below for other New Green Deals that we’ve found today, more on why going electric for your yard tools like the mower on sale is important, and of course Electrek’s best EV buying and leasing deals. Also, check out the new Electrek Tesla Shop for the best deals on Tesla accessories.

Amazon is offering a deal on the Greenworks 48V 17-inch Brushless Cordless Lawn Mower with 24V Drill/Driver for $245.99 shipped. Down from a $360 normal going rate, today’s deal is the third-best price that we’ve tracked all-time. This kit includes Greenworks’ 48V 17-inch brushless battery-powered mower, two 4Ah 24V batteries, a charger, and a 24V drill/driver. That’s right, you don’t just get the mower and batteries here, the drill/driver will help you with honey-do tasks around the house once spring arrives. Of course, no gas or oil is required for this mower to function, and being battery-powered also removes the requirement to have cylinders or noisy exhaust. All-in-all, this is a solid buy at the third-best price that we’ve seen all-time.

‘Battle of the sexes’ begins in womb as father and mother’s genes tussle over nutrition

Posted by in categories: biotech/medical, food

Cambridge scientists have identified a key signal that the fetus uses to control its supply of nutrients from the placenta, revealing a tug-of-war between genes inherited from the father and from the mother. The study, carried out in mice, could help explain why some babies grow poorly in the womb.

As the fetus grows, it needs to communicate its increasing needs for food to the mother. It receives its nourishment via blood vessels in the placenta, a specialised organ that contains cells from both baby and mother.

Between 10% and 15% of babies grow poorly in the womb, often showing reduced growth of blood vessels in the placenta. In humans, these blood vessels expand dramatically between mid and late gestation, reaching a total length of approximately 320 kilometres at term.

Scientists demonstrate a novel rocket for deep-space exploration

Posted by in categories: energy, satellites

The growing interest in deep-space exploration has sparked the need for powerful long-lived rocket systems to drive spacecraft through the cosmos. Scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have now developed a tiny modified version of a plasma-based propulsion system called a Hall thruster that both increases the lifetime of the rocket and produces high power.

The miniaturized system powered by plasma—the state of matter composed of free-floating electrons and , or ions—measures little more than an inch in diameter and eliminates the walls around the plasma propellent to create innovative thruster configurations. Among these innovations are the cylindrical Hall thruster, first proposed and studied at PPPL, and a fully wall-less Hall thruster. Both configurations reduce channel erosion caused by plasma-wall interactions that limit the thruster lifetime—a key problem for conventional annular, or ring-shaped, Hall thrusters and especially for miniaturized low-power thrusters for applications on small satellites.

Introducing the light-operated hard drives of tomorrow

Posted by in categories: computing, solar power, sustainability

Circa 2020


What do you get when you place a thin film of perovskite material used in solar cells on top of a magnetic substrate? More efficient hard drive technology. EPFL physicist László Forró and his team pave the way for the future of data storage.

“The key was to get the technology to work at room temperature,” explains László Forró, EPFL physicist. “We had already known that it was possible to rewrite magnetic spin using light, but you’d have to cool the apparatus to—180 degrees Kelvin.”

Scientists have a new theory explaining liquid water on Mars

Posted by in category: space

The theory rests on a phenomenon well-documented on Earth.


On early Mars, water hung on longer than it should have — that might be because of water clouds that prevented evaporation of rivers and lakes.

South Korean 20-Mile Solar ‘Bike Highway’ Generates Electricity

Posted by in categories: solar power, sustainability, transportation

Sunny way.


A ‘bike highway’ running between Daejon and Sejong in South Korea is a sight —or rather, a concept —, you surely haven’t thought of before: It stretches for 20 miles (32 km), and it not only shields cyclists from the sun but also generates power at the same time.

Hyundai shuts down its engine development team amid focus on electric cars

Posted by in categories: economics, sustainability, transportation

Hyundai announced that it is shutting down its internal combustion engine development team as the automaker focuses on electric cars.

For 40 years the Korean automaker has been developing internal combustion engines to use in its vehicle lineup, but no more.

The Korea Economic Daily reports that Hyundai’s new R&D chief Park Chung-kook confirmed in an email to employees that they are shutting down new engine development:
