Fusion Energy Gets Ready to Shine—Finally

had no real sense of how the sun and stars create their vast amounts of energy. Then, in October of that year, Arthur Stanley Eddington, an English astrophysicist, penned an essay elegantly titled “.” “A star is drawing on some vast reservoir of energy by means unknown,” he wrote. “This reservoir can scarcely be other than the sub-atomic energy which, it is known, exists abundantly in all matter; we sometimes dream that man will one day learn how to release it and use it for his service.

From that moment, scientists began the quest to harness unlimited, carbon-free power on earth. They've built more than 200 reactors that have tried to slam hydrogen atoms together and release fusion energy. It's a dream perennially called delusional, impossible, and “always 20 years away.” In 1985, recognizing that no country had the will to solve the world's most complicated puzzle alone, Ronald Reagan and Mikhail Gorbachev called for an international effort to give it a go.

In 1988, engineers began designing the International Thermonuclear Experimental Reactor, now just ITER. Along the way, 35 nations have split the $23.7 billion price tag to construct its 10 million parts. Now, surrounded by vineyards in France's Saint-Paul-lès-Durance, the 25,000-ton machine is set to be flipped on in 2025.

This Poloidal Field Coil Winding Facility is one of 39 buildings on ITER's 445-acre campus. Since the isotopes creating the fusion energy will be 10 times hotter than the sun, two layers of magnetic coils ringing the machine will keep them caged within. That silver doughnut is a cryogenic chamber that will stress-test the coils.The isotopes butting heads will be deuterium and tritium.

Please people in power don't create a bomb with this

We should all pray for and back efforts in fusion energy. It is the ultimate hurdle to safe sustainable energy, saving fossil fuels for the few essential items that require them.

I got dibs on the first iron man suit.

Strange support: Edward Morse, who teaches nuclear engineering at UCB, says it's the “only viable” hope we have to secure the energy we'll need over the next millennia: “It's Rosemary's baby. We have to pray for Rosemary's baby.”

No, 2027 earliest.

It will melt down before it will reach capacity.

Needing to flip a 25000 tonne machine suggests a lack of planning.

Safety concerns, regulatory delays, damaged components. COVID delays. Employee suicide. Death of Dr Bigot. ITER will not start tests until 2027 earliest, probably later. LauraMallonee

No thank you.

Iron man about to go live?

Iron man?

This article says it’s ready to be switched on by 2025 but then references it working by 2035. Which is it?

Apple Pauses Plans to Go From Two Days to Three Days a Week in the OfficeApple has paused plans to bring employees back to the office three days a week—up from two—following complaints from some workers I honestly think we need to socialize the computer nerds more from the start in grade school. They pose the biggest threat to humanity. Have you ever conceived in your life that an employer would tell you 3 days a week is enough, but then go and stick with 2 because of employees complaining? Not about a legal issue, but just out of sheer complaining. And would you consider such an employer responsible / good? 🤦‍♂️ wow

Chris Holtmann To Receive Three-Year Contract Extension With Ohio State Through 2027-28 SeasonChris Holtmann is receiving a contract extension worth $3.5 million per year that could keep him at Ohio State for the next six seasons. I guess we’re okay with being mediocre Imagine being mediocre at your job and getting 3.5 mill a year The only way this looks good, is if Holtmann wins a Big Ten and makes it past a sweet 16. At Ohio State, no matter the sport, they hire people that can win and compete for titles. Right now, winning (I say that lightly) is the only thing keeping Holtmann afloat.
