Hotter than the center of the sun — Tokamak Energy reaches target

The Oxford, England-based company’s spherical ST40 uses high-temperature superconductors (HTC) made from rare earth barium copper oxide (REBCO) to create strong magnetic fields to contain the hot plasma. The ST40 was started for the first time in April 2017.

Tokamak Energy aims to produce a record-breaking plasma temperature for a privately-funded venture of 100 million degrees. Think about that -That’s about seven-times hotter than the center of the sun.

“By working with one of the world’s most reputable engineering organisations we will turn the question over fusion energy from if to when.”

Jonathan Carling, Tokamak Energy CEO, said: “We are taking significant steps towards achieving fusion energy and doing so with the agility of a private venture, driven by the goal of achieving something that will have huge benefits worldwide.”

“Reaching 15 million degrees is yet another indicator of the progress at Tokamak Energy and a further validation of our approach. Our aim is to make fusion energy a commercial reality by 2030. We view the journey as a series of engineering challenges, raising additional investment on reaching each new milestone,” Carling said.

The ST40 is just warming up
The ST40 is the third machine in what is a five-part plan to achieve abundant, clean energy on an industrial scale by 2030. The goal of reaching 100 million degrees Celsius (180 million degrees Fahrenheit) is to have a high enough temperature to force deuterium and tritium particles together.

“The world needs abundant, controllable, clean energy,” says co-founder Dr. David Kingham. “Our business plan is built on strong scientific foundations and this milestone is a significant step in our compact spherical tokamak route to fusion power.”

Tokamak Energy has established itself as the world’s leading private fusion energy venture. The company went out on a limb by building their Tokamak reactors with a spherical compact design, a big step up from the original Russian tokamak T3 built in the 1960s. The T3 was a wide, ringed-doughnut shape, and was later proved to be far from the ideal design.

We are deeply saddened to announce the passing of our dear friend Karen Graham, who served as Editor-at-Large at Digital Journal. She was 78 years old. Karen's view of what is happening in our world was colored by her love of history and how the past influences events taking place today. Her belief in humankind's part in the care of the planet and our environment has led her to focus on the need for action in dealing with climate change. It was said by Geoffrey C. Ward, "Journalism is merely history's first draft." Everyone who writes about what is happening today is indeed, writing a small part of our history.
