FUSION STARTUP HELION HITS BLISTERING TEMPS AS IT RACES TOWARD 2028 DEADLINE

Summary from the TLDR newsletter

Fusion energy startup Helion has hit a key milestone: plasma inside its Polaris prototype reactor has reached 150 million degrees Celsius. The company's ultimate goal is to produce plasmas that hit 200 degrees Celsius. Its reactor design is different from its competitors, requiring plasmas about twice as hot to function as intended. Helion plans to extract energy using the fusion reaction's magnetic field rather than from heat. The company is contracted to sell electricity to Microsoft starting in 2028, but this will be through a larger commercial reactor called Orion, which is currently being built.
