Rare-earth metals and other minerals are essential for green tech like EVs and renewable energy. Trouble is, we need a lot of them and their availability on Earth is limited. But what if we could tap into all the materials flying around in space? Some scientists claim we could mine asteroids in the future. Yes, asteroids. Is it just an Armageddon remake or will we eventually…dig into them…?

Norway’s Wind Catching Systems (WCS) has made a spectacular debut with a colossal floating wind turbine array it says can generate five times the annual energy of the world’s biggest single turbines – while reducing costs enough to be immediately competitive with grid prices.

Standing more than 1000 ft (324 m) high, these mammoth Windcatcher grids would deploy multiple smaller turbines (no less than 117 in the render images) in a staggered formation atop a floating platform moored to the ocean floor using established practices from the oil and gas industry.

Just one of these arrays, says WCS, could offer double the swept area of the world’s biggest conventional wind turbines – the 15 MW Vestas V236 – and its smaller rotors could perform much better in wind speeds over 40 to 43 km/h (25 to 27 mph), when larger turbines tend to start pitching their blades to limit production and protect themselves from damage. The overall effect, says WCS, is a 500 percent boost in annual energy output, with each array making enough power to run 80000 European homes.

An emerging ransomware strain in the threat landscape claims to have breached 30 organizations in just four months since it went operational, riding on the coattails of a notorious ransomware syndicate.

First observed in February 2021, “Prometheus” is an offshoot of another well-known ransomware variant called Thanos, which was previously deployed against state-run organizations in the Middle East and North Africa last year.

The affected entities are believed to be government, financial services, manufacturing, logistics, consulting, agriculture, healthcare services, insurance agencies, energy and law firms in the U.S., U.K., and a dozen more countries in Asia, Europe, the Middle East, and South America, according to new research published by Palo Alto Networks’ Unit 42 threat intelligence team.

By grinding up nanotubes and dipping them in special solvents, the team showed it’s possible to generate enough current to run important electrochemical reactions, and maybe one day to power super-small devices.

Because it was, 62 years ago, the first fully reusable space vehicle, two stages, both reusable. The same concept of Virgin Galactic SpaceShipTwo.

X15 made 200 flights at suborbital altitude, 100 km.

The bike’s powertrain uses a fuel cell to turn gaseous hydrogen into electrical energy.

The engine setup holds its own, too. The Apex H2 will feature a hybrid powertrain that will convert gaseous hydrogen into electrical energy via a special fuel cell, reports New Atlas. Ninebot says the hydrogen-electric setup will be able to generate over 80 horsepower and rocket the bike from zero to 60 mph in less than four seconds. Considering that the original Segway—yes, the infamous two-wheel personal transporter favored by mall cops—topped out at 10 mph, that’s pretty impressive, even if it is slower than the Apex concept’s quoted top speed of 124 mph. Of course, there’s one key difference between the two bikes: The Apex H2 will be one of the rare concept vehicles you’ll be able to buy.

Flying taxis, more technically known as electric vertical take-off and landing (eVTOL) vehicles, might actually — finally — become a feasible technology thanks to a new development in battery technology.

Ironically, the hardest part of designing and building eVTOLs isn’t the vehicle itself. Instead, it’s solving the challenging energy situation that eVTOLs face: Any battery that’s powerful enough to lift the thing is almost certainly too heavy and slow-charging to make a trip worthwhile. But a team of Pennsylvania State University engineers tested new batteries that can both recharge in a matter of minutes and survive thousands of charge cycles, according to research published Monday in the journal Joule, making eVTOLs seem a whole lot more realistic.

The energy-dense lithium-ion batteries represent a major leap forward in electric vehicle energy tech, according to The Independent. Both could be charged for a 50-mile journal in under ten minutes, making eVTOLs far more economically viable because each vehicle could take more trips per day.

Researchers have discovered a new electronic property at the frontier between the thermal and quantum sciences in a specially engineered metal alloy—and in the process identified a promising material for future devices that could turn heat on and off with the application of a magnetic “switch.”

In this material, electrons, which have a mass in vacuum and in most other materials, move like massless photons or light—an unexpected behavior, but a phenomenon theoretically predicted to exist here. The alloy was engineered with the elements bismuth and antimony at precise ranges based on foundational theory.

Under the influence of an external magnetic field, the researchers found, these oddly behaving electrons manipulate heat in ways not seen under normal conditions. On both the hot and cold sides of the material, some of the electrons generate heat, or energy, while others absorb energy, effectively turning the material into an energy pump. The result: A 300% increase in its thermal conductivity.

Scientists in South Korea have made a breakthrough in battery research that could help us bust through a key bottleneck in energy storage. The team’s advance overcomes a technical issue that has held back highly promising lithium-metal battery architecture and could pave the way for batteries with as much as 10 times the capacity of today’s devices.

The reason lithium-metal batteries hold so much promise is because of the excellent energy density of pure lithium metal. Scientists hope to swap out the graphite used for the anode in today’s lithium batteries for this “dream material,” though this comes with some complicated problems to solve.

One of the key issues relates to needle-like structures called dendrites, which form on the anode surface as the battery is charged. These penetrate the barrier between the anode and the battery’s other electrode, the cathode, and quickly cause the battery to short-circuit, fail, or even catch fire.
