Hyperion launches futuristic hydrogen-fueled car

Carroll Shelby, who designed the classic Shelby Mustang in the sixties, once quipped: "I've always been asked, 'What is my favorite car?' and I've always said, 'The next one.'"

For futuristic automobile fans, "the next one" is here.

California-based Hyperion unveiled its XP-1 hydrogen supercar at a digital unveiling Wednesday and just brought the future one lap closer with its stunning, muscular configuration and eye-popping specs that leave the competition in the digital dust.

With a top speed of 221 mph, this powerhouse propels from zero to 60 mph in 2.2 seconds and can cruise for more than 1,000 miles on one tank of hydrogen.

The XP1 is not the first car to employ hydrogen for energy. The Hyundai Nexo, Toyota Mirai and Honda Clarity all use the lightweight gas. But they rely on lithium-ion batteries to help boost power. The XP-1 has ditched the weighty lithium-ion batteries and instead incorporated a carbon-fiber energy storage system feeding a proton exchange embrace (PEM) to provide power to each wheel.

Its only emissions are water vapor.

Dispensing with batteries, the car, built on a lightweight carbon-titanium metal-composite chasis, weighs in at a trim 2,275 pounds.

With its eye-catching design, compared by some to a Bugatti Chiron, the XP-1 boasts prominent air blades on either side that not only contribute to aerodynamic stability at high speeds but also incorporate solar panels that change positions to track the sun. That's an appropriate feature for a company named after a mythological Greek god of light.

"Aerospace engineers have long understood the advantages of hydrogen as the most abundant, lightest element in the universe and now, with this vehicle, consumers will experience its extraordinary value proposition," said Angelo Kafantaris, Hyperion CEO. "This is only the beginning of what can be achieved with hydrogen as an energy storage medium. The potential of this fuel is limitless and will revolutionize the energy sector."

The XP-1's appearance is drawing plenty of attention from car and tech publications: Ars Technica called it "a bit like a Bugatti Chiron that had a transporter accident with an IndyCar." Loz Blain of New Atlas termed it "jaw-dropping," adding, "It's absolutely outrageous, one of the most aggressively out-there and futuristic designs we've seen, from the wild gold-ringed vortex air ports on the front, back and sides to the huge clear-panel roof and some truly nutty rims."

Slightly less impressed was Motor Trend, which, while terming the car a head-turner and "striking," also noted, "Beautiful, the XP-1 is not. [Its] exterior look is both busy and incohesive." Clean Technica observed: "The XP-1 sports looks like a starfighter straight out of a science fiction novel."

One obstacle the XP-1 will need to overcome is the lack of fueling stations. U.S. Energy Information Administration data show that there were just 60 hydrogen station pumps available to the public as of the first of this year. More are expected to open as demand grows. Zero-emissions vehicle design company Nikola is setting up its own hydrogen station network to support its Nikola One trucks.

Hyperion has not released many of the specs of this prototype, but it reportedly is scheduling production of 300 XP-1s in 2022. The price is expected to be in the high six figures.

Scientists Have Discovered The Fastest Star Around A Massive Black Hole Travelling At 8% The Speed Of Light Through Our Milky Way!

 Scientists Have Discovered The Fastest Star Around A Massive Black Hole Travelling At 8% The Speed Of Light Through Our Milky Way!

 At the center of our universe is Sagittarius A* (SGR A*), a massive black hole about four million times the mass of the sun. Because SGR A* is so large, its gravitational effects are extreme and can be detected by looking at nearby stars. Swirling around SGR A* are stars and mysterious objects locked in a cosmic
two-step box along with this giant monster. These stars, along with the mysterious objects and SGR A*, are moving at an extreme pace.

 

However, Scientists Have Discovered The Fastest Star Around A Massive Black Hole Travelling At 8% The Speed Of Light Through Our Milky Way! A study published in Thursday’s (August 13) ‘Astrophysics Journal’ examined the region around SGR A* to find signs of stars. Previous studies have found that numerous stars tend to orbit these supermassive black holes in highly unusual orbits. Collectively known as S stars, these stars orbit very close to the black hole.

Because these S stars orbit very close to the black hole, they are tough to detect. However, the team examined images between 2004 to 2016. To explore these images, the team used instruments mounted on the Eastern Southern Observatory’s gigantic telescope in Chile. On examination, they found five new stars in the cluster, collectively known as S4711-S4715, while tracking their movements around SGR A*.

 

The results add to the evidence that a significant amount of stars orbit SGR A* at distances the size of our solar system. Because of their proximity to the deep abyss at the center of the Milky Way, these stars are well aware of the extreme physical phenomena.

Fastest Star Around SGR A* Travels At 8% The Speed Of Light.

 

A team of astronomers at the University of Cologne, Germany, has been studying the space region around the black hole. In January 2020, they reported the observations of the star S62. Their observations said that S62 orbits the black hole every 9.9 years, making it the shortest orbital period.



However, it also makes it the fastest star to flash around the Milky Way’s black hole. However, new data from the team showed a decline in both records for the S62. According to the Galaxy’s Telegram, one of its newly discovered stars, S4711, orbits the Milky Way’s black hole every 7.6 years. This is claimed to be the shortest orbital period ever recorded.
On the other hand, another star, S4714, is extreme and isn’t at the same distance as S4711 from the SGR A*. The S4714 is reportedly traveling around the black hole at 8% the speed of light. At this speed, the star is moving at about 15,000 miles per second and can reportedly circle the Earth in 1.5 seconds. The highly eccentric orbits of S stars provide further evidence for Einstein’s theory of general relativity.
 
Einstein’s theory predicts how space, time, and gravity interact. Simultaneously, it also suggests that large dense objects such as black holes can distort the space around them. By studying S stars, astronomers can see some of the motions predicted by Einstein’s theory. The team believes that improved data will provide a better understanding of the space around SGR A*. Simulatensouly, the team expects to find more stars in very tight orbits shortly.
