Two issues preventing the widespread uptake of electric vehicles are recharging time and lack of range. Now, scientists have shown one potential means of negating these issues. Their demonstration of electric power transfer via the car-wheel is claimed as the world’s first.

Electric vehicles can already be powered via infrastructure in the road. The South Korean city of Gumi uses a means of electromagnetic induction to power some of its buses. This newly-demonstrated method, however, uses radio frequency transmission.

The concept has been developed by Masahiro Hanazawa of Toyota Central R&D Labs and Takashi Ohira of Toyohashi University of Technology. It avoids the need for potentially dangerous contact conductivity devices by up-converting energy from power lines into radio frequency using high-speed inverters.

Morocco-born Dr Rachid Yazami has lived all over the world, thanks to an invention he made in his first year as a PhD student – the graphite anode – which is one of the key components that make lithium-ion batteries perform so well.

With electric vehicles on the rise, he believes the invention will soon take you everywhere, too.

Yazami’s story starts in the mid-1970s when scientists knew that graphite could help to form molten or powdered lithium into a usable energy storage material but struggled to turn it into a product. In 1983 Yazami and co-author Ph. Touzain cracked the problem by using a solid polymer electrolyte.

The high-lift wing shapes are more aerodynamic than conventional aircraft, giving the SE200 more efficiency and shorter takeoff and landing capabilities. Courtesy SE Aeronautics.

SE points to its integrated monocoque structure as a breakthrough for performance and safety. The company notes aircraft manufacturers bolt together large sections called “barrels,” in order to maximize production. “This is usually where fuselages break apart in an accident,” SE says. “SE will build a single-piece, tough composite fuselage.”

The monocoque design and composite materials will make the aircraft the most efficient ever built, claims the company, with a 50-year service life. “We will also be able to build these aircraft in less than half the time it takes to normally build an aircraft of its size,” it says.

Space mining. 😃

Is Space Mining Our Future Gold Mine? Get Surfshark VPN at https://surfshark.deals/undecided and enter promo code UNDECIDED for 83% off and 3 extra months for free! 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.

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.

Of course X15 was a military spaceplane, nothing like a civilian passengers transportation vehicle, yet the concept is important.

The first project of the Space Shuttle (Krafft Ehricke, early 70’s) was based on the same concept. But then such project was abandoned, in favor of a partially reusable machine, realized in 5 unic pieces.

We could have reusable launch vehicles since 40 years, at least.

Civilization could be well on its way of expansion in the solar system: Earth orbit industries, cislunar economy, asteroid materials use, producing fuel in space… topics for an ucronian novel?

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.

Ninebot says the bike will go into production in 2023, with deliveries expected to begin that same year. When the H2 does finally go on sale, the bike will join a varied Segway lineup that includes a Wall-E-esque motorized chair on wheels and a high-performance, Lamborghini-approved go-kart that can go 25 mph. You do you, Segway.
