Barca Ingenity day scufundă tehnologia cu skateboard-ul electric în apă

Vineri, 18 Februarie 2022 14:46

The Ingenity 22E is capable of hitting a top speed of 26 knots, but Ingenity doesn't estimate how long it will be out on the water at that speed

" Going from water sports action to luxury cruising, and moving from the waters of Tahoe to the shores of Miami, Florida's Ingenity has followed up its rowdy electric Super Air Nautique 22E multi-sport boat with the more humble 23E day boat. Along the way, it's borrowed some lingo from the electric car industry, basing the new boat around a "modular skateboard" that could serve as the basis for a whole family of models. By packaging its e-drive hardware below the waterline, it's also created a cleaner, more spacious triple-lounge deck for the captain and his or her 10 closest friends to enjoy during long, electric-driven days on the water.

With a 126-kWh battery pack, the new 23E only carries two extra kilowatt-hours of capacity compared to what the GS22E was holding when we looked at it in 2021. But since it's tuned for full-day cruising as opposed to fast, furious, adrenaline-driven water sports, the 23E can stay out on the water for as long as 14 hours during low-speed cruising, according to Ingenity. The GS22E, on the other hand, hits the water with a mere two- to three-hour runtime estimate. The 23E's forward-facing sterndrive is engineered for confident low-speed maneuverability, safety and performan "

„farfuria zburătoare” proiectată de MIT ar putea într-o zi să-și planeze drumul peste Lună

„farfuria zburătoare” proiectată de MIT ar putea într-o zi să-și planeze drumul peste Lună. Due to the fact that the Moon lacks a protective atmosphere, its surface is directly exposed to space plasma and the Sun's ultraviolet rays. This causes it to become positively charged, enough so that lunar dust levitates up to 1 meter (3.3 ft) above the ground – it's the same effect that causes our hair to stand up when statically charged. Previously, researchers have suggested utilizing this phenomenon in a spacecraft-deployed glider that would explore the surface of airless celestial objects like the Moon. If the wings were made of a positively charged material such as Mylar, it was reasoned that the glider and the positively charged lunar surface would repel one another, causing the glider to levitate. According to the MIT team, although such a setup might work on small asteroids, the force of gravity on larger celestial bodies such as the Moon would still pull the glider down. That's where the flying-saucer-like rover would come in.

Stark Varg: „Cea mai rapidă bicicletă electrică din lume”

Luni, 20 Decembrie 2021 08:34
This electric soil disperser claims to be the fastest, most powerful dirt bike on the planet Stark Future Barcelona startup Stark Future has launched this absolute weapon of an electric dirt bike, "to show that electric technology is superior to gasoline by outperforming all traditional motocross models available." That right there, folks, is a promise of world domination – but looking at the spec sheet, we sure wouldn't want to line up next to the Stark Varg on a 450. Thiweighs 110 kg (242 lb), which makes it 11 kg (24.2 lb) heavier than the FIM's minimum weight for an unfueled MXGP racer. So it is a tad on the porky side compared to international-grade racers, but that gap shrinks once the fuel goes in, and the Varg more than makes up for it when you open the throttle. *

The watch on your wrist has never been so useful, as demonstrated by our pick of 2021's best smartwatches (Samsung's Galaxy Watch4 Classic shown) It's been another bumper year for smartwatches, with manufacturers improving the technology that drives them while cramming in more features and better sensors. Here's our pick of the best smartwatches of 2021. The Apple Watch 6 topped our list of the best smartwatches for 2020, and continued to attract high praise from industry pundits and consumers alike during much of this year. Until Series 7 launched in September. Quite simply, if you have an iPhone in your pocket then this is the smartwatch for you. There are no headline-grabbing tech updates here, but Apple has significantly improved the display, which now offers almost 20 percent more screen area than the Series before, and the always-on Retina display is a lot brighter too.
