Industrial motors can spin at a head-spinning 250,000 revolutions per minute. But a new matchbook-sized motor runs circles around the competition.
Researchers from ETH Zurich’s Department of Power Electronics created a drive system in cooperation with its industrial partners that exceeded 1,000,000 rpm in tests.
Next year’s Mercedes EQS electric luxury sedan will be one of the longest range EVs on the market, the first real thorn in Tesla’s side.
HONG KONG (Reuters) — China launched its military build-up in the mid-1990s with a top priority: keep the United States at bay in any conflict by making the waters off the Chinese coast a death trap. Now, China’s People’s Liberation Army (PLA) is preparing to challenge American power further afield.
China’s shipyards have launched the PLA Navy’s first two Type 075 amphibious assault ships, which will form the spearhead of an expeditionary force to play a role similar to that of the U.S. Marine Corps. And like the Marines, the new force will be self-contained — able to deploy solo with all its supporting weapons to fight in distant conflicts or demonstrate Chinese military power.
New battery technology developed at Berkeley Lab could give flight to electric aircraft and supercharge safe, long-range electric cars.
In the pursuit of a rechargeable battery that can power electric vehicles (EVs) for hundreds of miles on a single charge, scientists have endeavored to replace the graphite anodes currently used in EV batteries with lithium metal anodes.
But while lithium metal extends an EV’s driving range by 30–50%, it also shortens the battery’s useful life due to lithium dendrites, tiny treelike defects that form on the lithium anode over the course of many charge and discharge cycles. What’s worse, dendrites short-circuit the cells in the battery if they make contact with the cathode.
The Rafale jets are 4++ generation aircraft and the Indian Air Force is exploring rapid deployment and operationalisation of the Rafale jets arriving in the country by end of this month from France.

New types of cathodes, suitable for advanced energy storage, can be developed using beyond-lithium ion batteries.
The rapid development of renewable energy resources has triggered tremendous demands in large-scale, cost-efficient and high-energy-density stationary energy storage systems.
Lithium ion batteries (LIBs) have many advantages but there are much more abundant metallic elements available such as sodium, potassium, zinc and aluminum.
The United Arab Emirates’ first interplanetary mission successfully took off from the southern tip of Japan on July 20th, sending up a car-sized probe bound for the planet Mars. The spacecraft, called Hope, will now spend the next seven months traveling through deep space, before inserting itself into Mars’ orbit in February.
Study shows the vaccine is safe, but it is still too soon to know if it can stop people from being infected.
Balloon-based internet is currently flying high in Kenya, a win the Alphabet subsidiary. Here’s what they’re planning next.
