Microsoft said Wednesday it has signed a power purchase agreement with nuclear fusion startup Helion Energy to buy electricity from it in 2028.

The deal is a notable vote of confidence for fusion, which is the way the sun makes power and holds promise of being able to generate nearly unlimited clean power, if it can be harnessed and commercialized on earth. For decades, fusion been lauded as the holy grail of clean energy — tantalizing because it’s limitless and clean, but always just out of reach.

As responding to climate change has become an increasingly urgent goal for companies and countries around the globe, investors have poured $5 billion into private fusion companies looking to turn that holy grail into electrons flowing through wires.

Microsoft’s agreement to buy electricity from Helion is the first time a fusion company has inked a deal to sell electricity, according to Andrew Holland, the CEO of the Fusion Industry Association.

“This is the first time that I know of that a company has a power purchase agreement signed,” Holland told CNBC. “No one has delivered electricity, and Helion’s goal of 2028 is aggressive, but they have a strong plan for how to get there.”

Helion was founded in 2013 and currently has about 150 employees, with headquarters in Everett, Wash. One of the early and most significant investors in Helion, Sam Altman, is also a founder of OpenAI, the artificial intelligence organization that developed the chat platform ChatGPT, in which Microsoft has invested many billions of dollars. Altman believes the two deals are equally important and correlated components of the future he sees for humanity.

“My vision of the future and why I love these two companies is that if we can drive the cost intelligence and the cost of energy way, way down, the quality of life for all of us will increase incredibly,” Altman told CNBC. “If we can make AI systems more and more powerful for less and less money — same thing we are trying to do with energy at Helion — I view these two projects as spiritually very aligned.”

If demand for and use of artificial intelligence continues to increase, then that will increase demand for energy, too.

The potential of fusion is “unbelievably huge,” Altman told CNBC. “If we can get this to work — if we can really deliver on the dream of abundant, cheap, safe, clean energy that will transform society. It’s why I’ve been so passionate about this project for so long.”

In 2021, Altman told CNBC he put $375 million into Helion. As of Tuesday, this is still his largest investment ever, Altman told CNBC. In total, Helion has raised raised $577 million.

Why Helion is announcing a 2028 goal now

As part of the power purchase agreement, Helion is expected to have its fusion generation device online by 2028 and to reach its target power generation of 50 megawatts or more within an agreed-upon one-year ramp up period. When the fusion device is fully up to speed producing 50 megawatts of energy, it will be able to power the equivalent of approximately 40,000 homes in Washington state.

While Helion’s deal with Microsoft is to get 50 megawatts online, the company eventually aims to produce a gigawatt of electricity, which is one billion watts, or 20 million times the 50 megawatts it is selling to Microsoft.

Microsoft will pay for the megawatt hours of electricity as Helion delivers them to the grid.

“This is a real PPA, so there’s financial penalties if Helion can’t deliver power. So we’ve really put our skin in the game on this too — that we believe we can deliver this power and are committed to it with our own financial incentives,” David Kirtley, CEO at Helion, told CNBC.

Altman advocated for the two companies to work together, he told CNBC, but the deal is the result of work Helion has done independently. “It was not my doing,” he said.

Microsoft and Helion have been working together for years, Kirtley told CNBC. “The first visit we had from the Microsoft team was probably three of our prototypes ago, so many years ago. And then we’ve been working very closely with their data center technology team here in Redmond,” Kirtley said.

After all, Microsoft needs power and has aggressive climate goals. Microsoft has a goal to have 100% of its electricity consumption, 100% of the time, matched by zero-carbon energy purchases by 2030. Carbon-free energy includes hydro, nuclear and renewables for Microsoft, a Microsoft spokesperson told CNBC.

“We are optimistic that fusion energy can be an important technology to help the world transition to clean energy,” Brad Smith, president at Microsoft, said in a written statement. “Helion’s announcement supports our own long term clean energy goals and will advance the market to establish a new, efficient method for bringing more clean energy to the grid, faster.”

For Helion to be able to deliver electricity generated by fusion to customers requires years of advance planning on the transmission and regulatory fronts.

In that way, announcing a contract now to sell electricity in 2028 gives Helion time to plan and to pick a location in Washington State to put this new fusion device.

“One reason we’re doing the announcement today is that so we can be working with the communities involved, we can be working with regulators, and the power utility on citing this right now,” Kirtley told CNBC. “Even five years is a short amount of time to be hooked up to the grid. And we want to make sure that we can do that.”

Indeed, the transmission system in the United States, meaning the series of wires that carry electricity from where it is generated to where it is used, is largely tapped out. Getting new power generation connected to the grid can take years. Helion is working with Constellation to secure its transmission needs.

‘We’re not here to build systems in a lab’

The best-known pathway to commercializing fusion is with a donut-shaped device called a tokamak. The international fusion project under construction in Southern France called ITER is building a tokamak, and Commonwealth Fusion Systems, a fusion start-up spun out of MIT which has raised more than $2 billion in funding, is using tokamak technology. For comparison, CFS plans to have its first power plant on the grid and selling electricity in the early 2030s. 

Helion is not building a tokamak. It is building a long narrow device called a Field Reversed Configuration.

Broadly speaking, Helion’s approach involves shooting plasma (the fourth state of matter after solid, liquid and gas) from both ends of the device at a velocity greater than one million miles per hour. The two streams smash into each other, creating a superhot dense plasma, where fusion occurs.

Helion is currently building its seventh-generation fusion machine, named Polaris, which it aims to produce electricity with by next year, Kirtley told CNBC.

“We’re not here to build systems in a lab. We’re here to sell electricity. This is always been the dream,” Altman told CNBC.

So far, Helion has been able to generate energy with its fusion prototypes, but it has not yet built a device that creates more electricity than it uses to run the fusion device. So the firm has a lot of work ahead.

To that, Altman says: “There were a lot of people that were doubting A.I. six months ago, too.”

“Either the technology here is going to work or not. There’s a lot of huge challenges still to figure out — how are we going to get the cost super-low, how are we going to manufacture at scale — but on the ability to actually do the physics, we feel very confident,” Altman told CNBC. “And I think it’s fine for people to doubt it. But also the way that you eventually reduced that doubt is to show to show people it actually works in the commercial setting, like delivering on this deal.”

Helion has been making progress on some key hurdles.

For example, the company has started making its own capacitors, which are sort of like super-efficient batteries and one of Helion’s very significant capital costs.

It has also started to make the very rare fuel it uses, helium three, which is a very rare type of helium with one extra neutron. It used used to get helium-three from the U.S. government strategic reserves.

Next up, Helion has to demonstrate that its devices can work reliably for long periods of time, and Kirtley has a team working on durability of the components used in the device.

If Helion can be successful, it’s going to be a landmark for the entire fusion industry.

“This really signals that a fusion era is coming. And we’re all very excited about it,” Kirtley told CNBC.

The race is on to replicate the power of the sun with fusion energy

Segway’s feature-packed E3 Pro electric scooter with Apple Find My hits new $500 Black Friday low (Save $200)

Segway’s Black Friday Sale is in full gear and currently seeing hundreds in savings and plenty of returning and new low prices on its e-scooters and e-bikes. One such standout is Segway’s latest E3 Pro Electric Scooter down at $499.99 shipped, and which seems to have disappeared from Amazon’s marketplace. Carrying a $700 MSRP since launching back at the top of October, we’ve only seen this model given $100 price cuts in its launch deal and the brand’s Halloween and early Black Friday sales. Now, with things having ramped up with increased savings now that Black Friday is in full swing, you can score a larger-than-ever $200 markdown to a new all-time low price, giving you an advanced upgrade to your commute that I have been loving so far since getting one a short time ago.

I’ve been riding around Brooklyn for a short time now with my own Segway E3 Pro Electric Scooter and have been loving my experience so far, as it’s a MAJOR step up from the very basic E22 model I’ve had for short travels since 2020. While power has been significantly ramped up from its E2 Pro predecessor, this new generation still retains a fairly lightweight 40-pound design, which I am able (as a not-so-strong person) to carry easily with one hand/arm up and down my second-story stoop.

Segway’s E3 Pro comes bearing a 400W motor (with 800W peaking) alongside a 368Wh battery, the combination of which delivers up to 34 miles of commuting support for your travels at up to 20 MPH speeds. The regenerative brake paired with the brand’s SegRange Optimization tech really lends towards the extended travel times here, with safety taken into mind with the SegRide stability enhancement tech, the latest traction control system, turn signaling, RGB ambient lighting for nighttime journeys, and a bright headlight. What’s more, security is bolstered by the Apple Find My inclusion for those worried about tracking it down should theft (or forgetfulness) occur.

One thing I have really been enjoying, especially when riding over more pot-hole lined streets, is Segway’s E3 Pro’s dual elastomer suspension, which does a great job of smoothing out overall rides, while providing added cushioning when sudden, jolting sections of the road (or debris/trash) are driven over. Along with all those, there are also additional features, including the previously mentioned rear electronic regen brake getting a companion front drum brake, as well as 10-inch self-sealing jelly tires, an IPX5 water-resistant build, a 265-pound total payload, and a 3-inch full-color LED screen for setting adjustments.

Be sure to check out Segway’s full official Black Friday Sale while it lasts for a short while longer, which can save you hundreds at the best prices of the year starting from $150.

Tesla has sold ~100 cars since entering the world’s largest country in July

Tesla has sold ~100 cars since entering the world's largest country in July

Tesla’s much-awaited entry into the Indian market has resulted in very slow sales to start, but it may not all be bad.

We’ve covered the years-long effort of Tesla to enter the Indian auto market. There have been a lot of intentions and fits and starts, but due to protectionist schemes in the country it never made a lot of sense for Tesla to enter.

That changed this year in March, when India waived EV import duties, allowing foreign firms to bring their cars in for sale. While India does have some strong local brands in Mahindra and Tata, this opened the gates to Chinese, German, Korean and American brands – namely, Tesla.

So far, other American companies have declined to bring their EVs to India, but Tesla opened its first showroom in Mumbai, India’s most populous city and financial capital, in July of this year. It opened a larger “Tesla Center” showroom in Gurugram, outside Delhi, this week.

So, Tesla is only getting started in India, but by all measures it has been an exceedingly slow start, according to the BBC.

Dealership data shows that Tesla has only sold “just over” 100 cars in India since July, an exceedingly low number by any measure – especially when considering the India is now the most populous country in the world, with a population of just under 1.5 billion.

Tesla’s rocky start included losing its head of Indian operations just before launching its first store, among a slew of other executive departures this year and last.

The numbers look a little less bad when comparing against EV sales in the country. While India has sold an impressive 2 million electric vehicles this year, the vast majority of them have been electric scooters.

Electric passenger cars are a much lower share at around 160k total unit sales this year so far, making up only around 3% of the passenger car market. And the majority of those are lower-cost domestic brands Mahindra and Tata or a growing section of Chinese challengers, with very few sales from overseas luxury brands.

Tesla could be included in that “luxury brand” list, largely due to the price of its imported vehicles. While the Model Y starts at $40k in the US, that price rises to 5,989,000 Rupees in India (~$67k USD). This is simply an unaffordable price for the vast majority of Indians – indeed, only around 1% of India’s auto sales are in the “luxury” category.

Further, EV infrastructure is not very well developed in the country. Tesla has one Supercharger in India, and two listed as “coming soon” in the Gurugram area. There are thousands of other charging points across India (and of course, drivers can charge overnight at home), but the number is still relatively low compared to the country’s population.

Meanwhile, other brands’ EV sales are growing well in India. The auto market as a whole has grown by about 13% this year in the developing country, but EV car sales have grown by 57% in the same period, rapidly outpacing the auto industry as a whole.

Much of that sales growth has been driven by Chinese EVs, which make up around a third of the market. That’s around ~60k Chinese EVs sold this year in India.

Even luxury German EVs from Mercedes, BMW and Audi have sold around 4,000 units so far this year, not a large number, but certainly dwarfing Tesla’s.

So while it’s tempting to look at Tesla’s poor numbers and make excuses about the size of the EV market, ability of Indians to afford luxury vehicles, or state of India’s charging network, it’s hard to compare that low ~100 sales number at any of the competition and label it as anything other than an extremely poor showing.

But, you do have to start somewhere, and the company is only a few months in. So we’ll have to see where it goes from here – though with the sales we’ve seen so far in Mumbai, entering the Delhi market is unlikely to forestall Tesla’s current global sales decline.

The 30% federal solar tax credit is ending this year. If you’ve ever considered going solar, now’s the time to act. To make sure you find a trusted, reliable solar installer near you that offers competitive pricing, check out EnergySage, a free service that makes it easy for you to go solar. It has hundreds of pre-vetted solar installers competing for your business, ensuring you get high-quality solutions and save 20-30% compared to going it alone. Plus, it’s free to use, and you won’t get sales calls until you select an installer and share your phone number with them.
