Building a working nuclear fusion reactor has proven to be a daunting challenge even for multiple wealthy nations, as we've seen with the much-delayed ITER project. However, a private start-up called Helion thinks it can build one and start supplying energy by 2028 by taking a different approach than other reactors. Founded in 2013, Helion is in the news thanks to a $425 million funding round, backed by billionaires like Sam Altman and Peter Thiel. With more than $1 billion raised, the company is now valued at $5.4 billion. Nuclear fusion, which combines hydrogen atoms to form helium, is the holy grail for green energy. It's carbon free, and unlike current nuclear plants, produces no long-term radioactive waste. At the same time, reactors could produce enough electricity to power small cities. Sustained fusion reaction that produces more energy that it consumes has never happened, though. The largest project, ITER (International Thermonuclear Experimental Reactor), is projected to cost up to $22 billion and won't go online until at least 2034 and still hasn't produced a sustained reaction. The longest fusion raction is 1,066 seconds (17 minutes and 43 seconds), set just recently by the EAST reactor in China. So how does Helion think it can succeed? Most experimental reactors compress plasma using magnetic or inertial confinement, which heats it enough to spark a fusion reaction. Once that happens, the fusion-generated heat powers a steam turbine to generate electricity.

Fuel (deuterium and helium-3) is injected into both ends of the hourglass shaped reactor, then heated to form a plasma. Magnets form the plasma into a donut shape and fire them at each other at speeds up to 1 million MPH. They collide in the narrow middle section of the reactor and are further compressed by magnets there. That heats them up to the magic 100 million degrees Celcius, creating fusion. "As the plasma expands, it pushes back on the magnetic field from the machine's magnets," Helion explains on its website. "By Faraday's Law, the change in field induces current, which is directly recaptured as electricity, allowing Helion's fusion generator to skip the steam cycle." This system is simpler and potentially more efficient than a steam turbine. However, while the company has achieved fast enough pulse rates to achieve fusion, it has only done so on a small scale to date. "There [are] some big engineering challenges to get to those high repetition rates at the kind of big pulse powers where we talk about millions of amps," CEO David Kirtley told TechCrunch. And that's the rub with every other reactor. Fusion produces a huge surge of energy all at once and so far no one has been able to control and harness that. Helion thinks its simpler system will help, but has yet to prove it can do it experimentally, let alone commercially. Still, the company say sits seventh-generation reactor, Polaris, is now "in operation" but has declined to share any results to date.

Lucid's newly launched Gravity SUV will be able to access Tesla's Supercharger network across the US and Canada starting on January 31. And since the electric vehicle comes with a built-in port that supports the North American Charging Standard (NACS), it doesn't need an adapter to be able to plug into Tesla's Superchargers. The automaker says Gravity became the first non-Tesla model to be sold with a NACS charging port when its first production models were delivered to an initial batch of customers in December 2024. At the moment, only the more expensive $94,900 Grand Touring model is available for purchase, but the company plans to release the $79,900 Touring model sometime in late 2025. Emad Dlala, VP of Powertrain at Lucid, said the automaker developed a "new, unique technology" to ensure the Gravity's full compatibility with chargers rated at 500V and 1,000V. To be exact, the Lucid Gravity has a 926V charging architecture, so charging times will differ based on the charging station it's plugged into. Dlala said that the technology the company developed allows the Gravity to "charge seamlessly at up to 400 kW on 1000V charging equipment and at sustained speeds of up to 225 kW on 500V architecture fast chargers, including Tesla V3 Superchargers." Lucid pledged to support the North American Charging Standard back in 2023 and vowed to give its customers access to an adapter for its vehicles. The company said that the Lucid Air, its electric sedan that doesn't currently come with built-in NACS ports, will also gain access to Tesla's Supercharger network sometime this second quarter.
