CNN: Google just bought 200 megawatts of fusion energy that doesn't even exist yet

Google just bought 200 megawatts of fusion energy that doesn’t even exist yet
By Ella Nilsen

Tech giant Google is investing money into a futuristic nuclear fusion plant that hasn’t been built yet but someday will replicate the energy of the stars. It’s a sign of how hungry big tech companies are for a virtually unlimited source of clean power that is still years away.

Google and Massachusetts-based Commonwealth Fusion Systems announced a deal Monday in which the tech company bought 200 megawatts of power from Commonwealth’s first commercial fusion plant, the same amount of energy that could power roughly 200,000 average American homes.

Commonwealth aims to build the plant in Virginia by the early 2030s. When it starts generating usable fusion energy is still TBD, though the company believes they can do it in the same timeframe.

Google is also investing a second round of money into Commonwealth to spur development of its demonstration tokamak — a donut-shaped machine that uses massive magnets and molten plasma to force two atoms to merge, thereby creating the energy of the sun.



Commonwealth, an MIT spin-off (in my estimation) is one of the best bets to bring commercial fusion to the US.

Yeah, I hate the headline OKIsItJustMe Jul 2 #2
Fusion is inevidable. It's just taking its time getting here. marble falls Jul 2 #3
We've had nuclear fusion for several decades now (not counting "hydrogen bombs") OKIsItJustMe Jul 2 #6
But up to now: no commercial enegy is being produced by fussion or cold fussion. marble falls Jul 2 #7

They’re making a speculative investment…

Microsoft made a similar investment in Helion Energy.

The difficult part is getting more energy out than is put in. The NIF (although it gets a lot of press) was not intended to produce useful energy.

Commonwealth, Helion (and several other companies) are building reactors to produce useful energy. I’m pulling for Helion, because Commonwealth’s reactor will generate electricity the old fashioned way, by driving a steam turbine. — That being said, Commonwealth’s more conventional approach may give it an advantage.

If Commonwealth is first to market, I won’t be upset in the slightest.

However, both Commonwealth and Helion have (I think) realistic paths to success.

I think Helion may get there first, but I would be pleased as punch to see them both produce commercially viable fusion reactors.
