This is also the fastest IPMSM built with commercialized lamination materials.
Researchers at the University of New South Wales Sydney have developed a new electric motor that can clock 100,000 revolutions per minute. The high power density achieved as a result of this new design could help reduce the weight of electric vehicles (EVs) and thereby increase their range, a university press release said.
EV makers around the world have been looking for ways to address the range anxiety of their battery-powered vehicles. One of the options is to increase the size of the battery pack, which also increases the weight of the vehicle, creating more problems to solve.
To begin with, it will only run at a fraction of its eventual three-quadrillion-watt maximum output.
A laser at the University of Michigan, which is set to be the most powerful in the United States, is preparing to send its first laser pulses into an experimental target, a press statement explains.
The laser, named the Zetawatt-Equivalent Ultrashort pulse laser System, or Zeus, will be used to investigate quantum physics as well as outer space. It is hoped studies using the laser will also help to build new technologies in electronics and medicine.
The Starlink dish can withstand extreme temperatures as low as-22 degrees Fahrenheit.
SpaceX’s Starlink internet service is now available in one of the most remote regions of the world: Antarctica, making the service available on all seven continents.
In a tweet on Wednesday, the National Science Foundation announced the milestone, stating that scientists with the U.S. Antarctic Program were “over the moon” and have been testing out a Starlink dish at the McMurdo Station, a U.S. research facility based on an island right off the coast of Antarctica to supply increased internet bandwidth.
So far, Chinese scientists have achieved a reaction running at a slightly cooler 70 million degrees celsius for more than 17 minutes.
China aspires to produce unlimited clean energy through nuclear fusion by 2028.
The “world’s largest” pulsed-power plant will be built in Chengdu, Sichuan province, according to Professor Peng Xianjue of the Chinese Academy of Engineering Physics, The Independent reported on Wednesday.
We’re looking at you, Betelgeuse.
A team of astronomers believes they have found an effective method for predicting a supernova, a report from Space.com reveals. While stars do expand to massive sizes and become red giants before their demise, we have had no way of knowing how long it will take for a red giant to go supernova. It could take hundreds of thousands, if not millions, of years.
All of that has just changed though, thanks to a team of astronomers that has devised a method for spotting stars that are likely to supernova within only a few years — a tiny fraction of time in the context of astronomy.

Only two of the top 10 billionaires registered gains.
The world’s top richest people collectively lost $50 billion of their personal fortune as the New York Stock Exchange slumped on Tuesday amidst fears of rising inflation and looming inflation. Elon Musk, Jeff Bezos, Warren Buffet, Google Guys, nobody was spared as prices of stock held by them tumbled, Market Insider.

Even as most people struggled to balance their work and life during the pandemic, the world’s top billionaires were struck gold and saw their fortunes soar. According to a CBS report in 2021, the first year of the pandemic gave a $4 trillion boost to the billionaires’ wealth, raising the call for a “wealth tax.”
China appears to be a leader in maglev technology and continues to find innovative ways to use it.
A car equipped with magnetic levitation (maglev) technology has been successfully tested on a highway in East China’s Jiangsu province, according to an article by China Daily.
Provincial transport authorities are testing a new highway lane for maglev cars. The experiment saw a 2.8-tonne car float 35 millimeters above the road and run smoothly on a highway without crashing or veering.

Kardashev Civilizations are beyond immense, with even the first tier of them making any modern nation look miniscule, and there are many barriers to becoming one.

It seems that everyone is getting ready to embrace the metaverse, with more corporations and agencies supporting the online platform. Capitalizing on the world’s interest, Meta announced that they will be opening 10 metaverse campuses as part of a project.
With more universities accepting digital media and making courses about them, having schools focused on the online platform makes sense. Are people going to widely accept this as a form of education from here on out? Let’s wait and see.
