Private investment fuels race for nuclear fusion power in US | The Express Tribune

Published

WASHINGTON:

Spurred on by major technological advances and huge private investment, the United States’ nuclear fusion sector could be producing electricity within ten years, industry players say.

The process, which powers the Sun, sees two atomic nuclei combine — and release massive amounts of energy. But private companies on Earth are also hoping decades of research might finally culminate in fusion power plants being connected to the grid in the 2030s.

The buzz comes amid an influx of cash: in two years, the private sector has more than doubled its investments, reaching a total of $5.9 billion at the end of 2023, compared with just $271 million from the public sector.

Part of the hype is derived from what experts see as an impending tipping point, where theoretical science will soon become a reality.

“It’s not just about doing science, it’s actually about delivering products,” said Dennis Whyte, from the Massachusetts Institute of Technology.

Around two-thirds of start-ups from various countries, surveyed by the Fusion Industry Association (FIA), see the first fusion power plant connected to the power grid by 2035 at the latest.

Last year, Helion Energy, a fusion power start-up in Washington state, even signed an agreement with Microsoft for 50 megawatts (MW) of capacity to be operational by 2029.

“Remarkable things have happened just in the last couple of years,” said Pravesh Patel, of the start-up Focused Energy, at the CERAWeek energy conference.

“It’s like the first time the Wright brothers took off the ground,” he said, referring to the first ever flight of a powered aircraft in 1903. “People can see that it’s possible. It’s no longer theoretical.”

Major recent milestones include an experiment by the Lawrence Livermore National Laboratory (LLNL) in California in December 2022, in which more energy was released from the fusion than was used to produce it.

Fusion consists of assembling two atomic nuclei derived from hydrogen, usually deuterium and tritium, in a confined enclosure, at a heat of over 100 million degrees Celsius.

Together, they form a helium nucleus and release neutrons, which bombard the reactor walls and raise their temperature.

This heat is then converted into electricity, via steam produced when water comes into contact with the outside of the reactor.

Fusion has the advantage of being emissions-free. It also produces less waste than its cousin fission and cannot cause a radiation disaster.

Most start-ups have opted for the magnetic confinement technology used in the tokamak, the best-known reactor model. This differs from the inertial confinement method chosen by LLNL, which uses lasers.

Helion, on the other hand, recovers energy directly from inside the reactor, without using steam, and its process produces less neutrons, thus reducing projections on the walls and their erosion.

Such methods “offer an advantage in getting to commercialization,” a Helion spokesperson said.

Until recently, the economic viability of nuclear fusion appeared uncertain, as magnetic confinement required the manufacture of gigantic magnets.

But recently published studies by researchers at MIT and start-up Commonwealth Fusion Systems have shown that fusion is possible with much smaller magnets than originally imagined.

“Overnight, this has divided the cost per watt by 40,” Whyte told MIT News. “Now fusion has a chance” to become a reality in energy supply, he said.

With $2 billion in private capital, Commonwealth is by far the company to have raised the most funds in the sector. It plans to activate its demonstration reactor, SPARC, next year, then open its first power plant in the early 2030s.

Many uncertainties remain, but if Commonwealth and Helion are successful, it would enable the United States to become the first country to produce commercial electricity through fusion, a step no other nation is aiming for before 2035 at best.

“Commonwealth is a great example of what you can do, and how fast you can go, when you have this commercial incentive in the private sector versus in the public sector,” Patel said.

“The US has a particularly excellent track record of this,” Whyte said, noting the ability of university labs to translate research into products — often more smoothly than labs do in other countries — as well as a strong venture capital sector to enable start-ups to get off the ground.

From the semiconductor revolution to that of the Internet, “the US has won these kinds of races,” Whyte said.

SpaceX achieves unprecedented feat in commercial space travel | The Express Tribune

Published

on

By



WASHINGTON:

Two astronauts, a billionaire and an engineer, completed the first private spacewalk in orbit on Thursday outside a SpaceX capsule. They wore a new type of spacesuit in a high-risk feat once limited to astronauts from government space agencies.

As part of the Polaris Dawn mission, the astronauts each spent about 10 minutes outside the Crew Dragon capsule, tethered for safety, while their two crewmates remained inside. The mission, led by Elon Musk’s SpaceX, further pushed the boundaries of private space travel.

Jared Isaacman, a pilot and founder of Shift4, was the first to exit, followed by SpaceX engineer Sarah Gillis. Meanwhile, their crewmates Scott Poteet and Anna Menon observed from inside the capsule. Orbiting about 450 miles (730 km) above Earth, the entire spacewalk lasted one hour and 46 minutes.

Isaacman, who also funded the Polaris mission, previously financed his Inspiration4 flight with SpaceX in 2021. The mission, streamed live on SpaceX’s website, tested new equipment, including slimmer spacesuits and a procedure to fully depressurise the Crew Dragon cabin – technology that Musk aims to refine for future private missions to Mars.

After re-entering the spacecraft, Isaacman commented on Earth’s beauty, as seen from space. This mission was one of the riskiest for SpaceX, the only private company capable of regularly sending people into orbit and back.

Before the spacewalk at around 10:52 GMT, the capsule was completely depressurised, with the astronauts relying on their SpaceX-designed spacesuits for oxygen via an umbilical connection to the capsule. Isaacman, 41, and Gillis, 30, tested the suits’ flexibility and provided feedback to improve future designs.

The mission aimed to push the limits of private companies in space, with ground teams at SpaceX’s California headquarters monitoring the hatch’s closure and carrying out safety checks as the astronauts returned inside.

The spacewalk procedure echoed that of the first US spacewalk in 1965, which involved depressurising the capsule and tethering a spacesuited astronaut to it. NASA Administrator Bill Nelson hailed the mission as a “giant leap forward” for the commercial space industry and NASA’s goal of building a sustainable US space economy.

While Isaacman has not revealed the mission’s cost, it is expected to run into hundreds of millions, with Crew Dragon seats typically costing around $55 million each.

Gillis, who joined SpaceX as an intern in 2015, and Poteet, a retired US Air Force lieutenant colonel, were among the crew, along with SpaceX engineer Anna Menon. Throughout the mission, the spacecraft circled Earth multiple times, reaching altitudes of up to 1,400 km, the farthest humans have travelled in space since Apollo’s final mission in 1972.

Spacewalks have previously been conducted solely by government-trained astronauts. Since the International Space Station (ISS) was established in 2000, there have been around 270 spacewalks, with 16 on China’s Tiangong space station.

The Polaris crew spent two and a half years training, including mission simulations and challenging real-world experiences, to prepare for the mission, according to Poteet.

Currently, a record 19 astronauts are in orbit, including 12 aboard the ISS, after a Russian Soyuz mission transported additional astronauts there on Wednesday. Since 2001, Crew Dragon has completed more than a dozen astronaut missions, primarily for NASA.

The capsule was developed under a NASA programme to create commercial vehicles for transporting astronauts to and from the ISS. Boeing’s Starliner capsule, also part of this programme, launched its first astronauts to the ISS in June but faced difficulties. It returned empty, leaving its crew aboard the station until next year, when a Crew Dragon capsule will retrieve them.

The demand for the PS5 Disc Drive has skyrocketed since the announcement of the PS5 Pro, with online retailers quickly selling out of the popular peripheral.

Gamers eager to ensure they can still play physical media on their next-gen consoles are rushing to purchase the external disc drive required for the new PS5 Pro.

Sony officially revealed the PS5 Pro earlier this week, and with it came the announcement that the console would not include a built-in disc drive.

Instead, players who want to use physical discs will need to buy the external PS5 Disc Drive, a shift that has already sparked a buying frenzy.

At the time of writing, the PS5 Disc Drive has climbed to #16 on Amazon’s best-selling video game products.

Best Buy, one of the major online retailers, has already sold out of the drive, and it is currently unavailable for order. Gamers are still able to find it on other major sites like Target, Walmart, and PlayStation Direct, but these supplies are expected to diminish quickly as well.

This rush to secure the PS5 Disc Drive began when Sony introduced the PS5 Slim in late 2023, which also required an external drive for physical game compatibility. Unlike the original PS5, which featured both disc and digital editions, the Slim removed the option of having a built-in disc drive.

Americans consumed more than 100 trillion megabytes of wireless data in 2023, a 36% rise from the previous year and the largest single-year increase, according to a report from wireless industry association CTIA.

The surge in usage—an increase of 26 trillion MB over 2022—is attributed to the growing adoption of 5G devices and fixed wireless access (FWA) broadband services.

The total number of wireless connections in the US rose to 558 million, representing a 6% growth over 2022. Notably, 40% of wireless connections were 5G-enabled, covering over 330 million US residents.

Additionally, nearly 40% of all wireless devices were connected to 5G, a 34% increase from 2022.

CTIA highlighted that the sector attracted $30 billion in investment in 2023, with total spending on spectrum auctions surpassing $233 billion.

However, the association emphasized the need for Congress to restore the Federal Communications Commission’s (FCC) auction authority to ensure access to mid-band spectrum and meet the growing demand for wireless services.

By the end of 2023, the US had 432,469 active cell sites, a 24% increase since 2018, thanks to siting reforms.

The cost per megabyte of wireless data has dropped by 50% since 2020.

CTIA’s annual survey has tracked the US wireless sector since 1985.

Black Sun Productions, a virtual reality studio, has announced its debut title, Metamorphosis VR, will launch on October 10, 2024.

The narrative inspired by Franz Kafka’s The Metamorphosis will be available for Meta Quest 2 and 3.

This VR game offers a unique and immersive experience, allowing players to step into the surreal world of Kafka’s renowned novella.

Metamorphosis VR is a bold reimagining of the 2020 PC game Metamorphosis, originally developed by Ovid Works and Untold Tales.

The story takes place in early 1900s Vienna, following Gregor Samsa, a traveling salesman who undergoes a shocking transformation into a cockroach.

After a night out, Gregor awakens to discover his metamorphosis and embarks on a strange journey to find a way to return to his human form and save his closest friend.

“We chose Metamorphosis as our debut title for Black Sun because its surreal, Kafkaesque world – some of the richest and most immersive environments imagined – offers a perfect opportunity to bring this extraordinary experience to virtual reality,” said Corbin Chase, CEO of Black Sun Productions, in a statement, as reported by VentureBeat.

“One of VR’s most powerful abilities is how it changes our perspective and sense of scale, and Metamorphosis uniquely combines confusion, bewilderment, wonder and beauty. All imparted by that shift in perspective, it feels like this game was always meant for VR.”

One of the game’s key highlights is its distinct shift in perspective, which allows players to experience Gregor’s new reality as an insect.

Navigating through walls, floorboards, and tight spaces, the player is immersed in a bizarre world filled with bug philosophers, insect crime bosses, and creepy thespians.

The game features over 100 insect characters, each with a unique voice, contributing to an interactive experience.

Fans of Kafka’s original novella and virtual reality enthusiasts eager to explore its surreal world are anticipating the game’s October 10 release on Meta Quest 2 and 3.
