Peter Thiel Panthalassa Investment – Why a Climate Skeptic Just Bet $140M on the Ocean

Peter Thiel, a man who has openly ridiculed climate activism and once likened Greta Thunberg to the antichrist, is leading a $140 million funding round for a business that markets itself, in part, on clean energy credentials. There’s something subtly ridiculous about this. And yet, here we are. The investor list for the deal, which closed earlier this week, looks like two entirely different decks of cards were mixed together. On one side is Thiel. Conversely, green-tech VC’s patron saint is John Doerr. In the middle, with a courteous nod, is Marc Benioff’s TIME Ventures.

Named after the ancient ocean that encircled the supercontinent Pangaea, Panthalassa is the company at the heart of it all. Founded in 2016, this Portland, Oregon-based startup has spent the majority of its existence as the kind of small, technically ambitious startup that climate-tech reporters occasionally write about before forgetting about it. That is no longer the case. Artificial intelligence, or more precisely the persistent issue of where to locate all the computers that power it, is what has obviously changed.

It takes a moment to take in the pitch because it is so unusual. Panthalassa creates massive floating spheres that bob in the planet’s most energy-dense wave zones, resembling industrial buoys. The intriguing part is that each node harvests wave energy, transforms it into electricity, and then uses that electricity on board to power AI chips. The cooling is provided by the chilly seawater. The inference results are transmitted back to land via a satellite link. There are no transmission losses. No disputes with nearby utilities. The hum of a hyperscale data center has not prompted any zoning complaints from suburban neighbors.

Perhaps this is the most elegant way to describe the future of AI infrastructure to date. Terrestrial data centers are encountering obstacles due to grid limitations, water scarcity, permitting disputes, and local opposition. Nearly all of that is avoided by putting the computation in the ocean. It’s another matter entirely whether the engineering can withstand years of storm surges, saltwater corrosion, and the harsh physics of the open Pacific. Only two prototypes have been deployed by Panthalassa thus far, in 2021 and 2024. Later this year, the third generation is expected to go on sale.

The CEO, Garth Sheldon-Coulson, discusses ocean power in the same way that proponents of nuclear power discuss fission: it is one of three genuine solutions to the issue of producing tens of terawatts of additional capacity, along with solar and nuclear. Even though the framing is similar to what founders say when they’re trying to raise money, there’s something appealing about it. Investors appear to have faith in him. The phrase “the ocean frontier,” which is half-poetic and half-marketing, is exactly what you would expect from Thiel.

As this develops, it’s difficult to ignore the similarities to how Tesla was viewed ten years ago: mocked, then accepted, then abruptly at the center of the discussion. It’s unclear at this point whether Panthalassa stays on the same course or discreetly spends its $140 million in the salt and the swell. The factory is being constructed close to Portland. The nodes for Ocean-3 are being put together. Commercial deployment is scheduled for 2027, which in startup years is most likely 2028. Even though the people writing the checks cannot agree on why the planet needs to be saved, there’s a sense that something truly new is being attempted here.
