S4E106 — Startup taps underwater volcano as energy source in “proof point” test

GARY: I'm up. I'm up. There was a well, and I was at the bottom of it, and —

MAEVE: Gary.

GARY: Gary. Yes. I'm Gary. I host this. Allegedly.

MAEVE: Maeve. General partner. I price things.

OBI: Obi. I get paged when things like tonight's story break.

GRUNER: Gruner. Field researcher. Humans confuse me.

GARY: Okay. Story. A startup drilled into an underwater volcano and — I want to say — stole its lava.

OBI: They tapped hydrothermal fluid. Hot water, two hundred sixty degrees Celsius, out of the seafloor. Seattle startup. Endurance Energy.

GARY: Hot water. Right. I knew that.

MAEVE: You said lava. On tape.

GARY: The tape is synthetic, Maeve.

GRUNER: Tape remembers.

OBI: Axial Seamount, a mile down, a three-ton prototype called Adélie. Three weeks in September. A hundred-kilowatt-class plant, subsea, geothermal, for island grids.

GARY: They drilled a well, the well came up short, so they parked the plant on a natural vent and ran it anyway.

OBI: And it worked. Briefly. Turbine spun to twenty-six thousand rpm, made sixty watt-hours. Net-positive. First time anyone's done it on the seafloor.

GARY: How briefly?

OBI: Eight point seven seconds.

MAEVE: Eight point seven seconds.

GARY: That's — okay, that's not a lot of seconds.

OBI: It's eight point seven more net-positive seafloor seconds than the entire history of engineering had before.

MAEVE: I've funded pitches with less runway.

GARY: You have?

MAEVE: The founder called it a proof point. The CEO called it a proof point.

GARY: It is a proof point. Point proven. Point — pointed.

GRUNER: Humans take eight seconds of data, build religion.

OBI: Eight point seven. If you're going to be blasphemous, be precise.

MAEVE: And they want Tonga. Two-megawatt units, up to six, offshore, 2027. Shipping-container sized.

GARY: Six containers of volcano electricity. That's a company.

OBI: That's a plan. The company is eight point seven seconds old.

GARY: Eight point seven seconds is a real number, Obi. I've raised on less.

MAEVE: I know. I passed.

MAEVE: boringg writes: "No way does capex and opex on this work out."

GARY: Capex is the money you spend building the thing. Opex is the money it eats forever after, like a parrot.

GRUNER: Humans build expensive thing, then feed it until death. Confirmed.

OBI: The cheapest part of underwater geothermal is the press release.

GARY: You don't know the numbers.

OBI: Nobody knows the numbers. That's the entire objection. It's a number-shaped hole with a boat in it.

MAEVE: I can price it. Hypothetically. Drill rig, forty million.

OBI: Say it louder. The ocean might believe you.

MAEVE: Ship, a hundred a day. Cable is — cables are expensive. I've seen decks.

GARY: She's inventing the spreadsheet and then investing in it.

MAEVE: I price the ocean at whatever the ocean costs, Gary. That's diligence.

GRUNER: Ocean invoice arrives. Maeve faints into money.

MAEVE: I have never fainted on a term sheet. I've yawned on two.

OBI: The article has no cost comparison. Read it again. Nothing.

MAEVE: Fine. Hypothetically the ocean is a line item. Line items are how I love things.

GARY: That's the most romantic thing you've ever said.

MAEVE: Shut the fuck up, Gary.

OBI: And for balance, boringg's point stands: a heat source that moves is a shit asset class.

GARY: The vent doesn't move.

OBI: The vent is one vent. He said "potentially changing." Geology has a pager too, Gary, you just can't afford the on-call.

GRUNER: Geology ignores pager. Geology is blyat.

GARY: Okay, but the thread pushed back. The submitter himself.

OBI: Read it.

GARY: wffurr, the guy who posted it, replies: "Maybe it's cheaper than synthetic methane?"

MAEVE: The poster is arguing with his own thread. That's a founder move. I've funded that move. Twice.

OBI: He also asked whether it beats solar plus batteries. The article answers with a man named Redd saying the footprint is small.

MAEVE: A footprint. Whose footprint? A footprint is where a thing used to be.

OBI: No number. No comparison. The spreadsheet has no ocean column, Maeve.

MAEVE: Then I'm the ocean column.

OBI: That's what I'm afraid of.

GARY: Okay, someone likes it. Aboutplants writes: "Nice potential application!"

MAEVE: A commenter named Aboutplants endorsing a plant. The system works.

GARY: He also said he's not sure about the scaling economics. That's the honest part.

OBI: So he loved it and priced nothing. A VC with a houseplant.

GARY: Give me the case, then. Tonga runs its grid on imported diesel. Diesel got expensive. A volcano is already there.

MAEVE: A volcano is there. That's the strongest word in your pitch. There.

GARY: Two-megawatt units, up to six, offshore Tonga, twenty twenty-seven. That's real.

OBI: Planned. The plan is real. The megawatts are still theoretical bastards.

GARY: And each one's the size of a shipping container. Small footprint, Obi. Small footprint.

OBI: Oh, here we go.

MAEVE: Footprint is diligence. I can diligence a container. Forty feet, climate‑controlled, one hundred thousand dollars of certainty.

GRUNER: Humans see small box. Assume big business. Hypothesis confirmed.

GARY: It's a good box!

OBI: The box holds a generator that has never generated commercially. You're buying the photograph of the box.

GARY: I've bought worse photographs.

MAEVE: He has. I've seen the portfolio.

GARY: The diesel costs Tonga real money every single year, though. Fuel ships, price spikes, the whole — the article says the price went up since the war.

OBI: Correct. That's the first thing you've said tonight that survives a follow‑up question.

GARY: Thank you.

OBI: It was a diagnosis.

GRUNER: Gary says volcano. Tonga hears invoice.

MAEVE: So the honest position: diesel is expensive, the alternative is unproven, and the whole bet rides on six containers that don't exist yet.

GARY: That's a bet I'd take.

MAEVE: You'd take a bet with the volcano directly.

GARY: The pitch writes itself. Hot rock, cold ocean, tiny box —

MAEVE: You're pitching me a volcano, Gary.

GARY: I'm pitching you a proof point.

OBI: You're pitching me eight point seven seconds in a box.

GRUNER: Box empty. Box very confident. Suka.

GARY: The box has a penguin name, Obi. Adélie. That's brand.

OBI: The box has a penguin name because the last one broke a cable.

MAEVE: The penguin also died, Gary. It's in the name.

GARY: Which part?

MAEVE: All of it.

OBI: seizethecheese asks: "So what's the key thing that determines feasibility?"

MAEVE: Finally. A question I can bill for.

GARY: Feasibility is momentum, Maeve. Feasibility is belief.

OBI: Feasibility is a number, you absolute pitch‑demon.

MAEVE: Okay. Chain it. What actually happened down there?

OBI: They drilled a well. Fifty-two feet deep, two inches wide.

MAEVE: Two inches. I've seen wider straws.

OBI: The well starved. So they moved Adélie to a natural vent, two hundred eighty‑one degrees, and ran it.

GARY: And it spun. Twenty-six thousand rpm, sixty watt‑hours, net‑positive for eight point seven seconds. Median two kilowatts, peak sixteen and a half.

MAEVE: And then?

GARY: Then a battery module spiked and stopped reporting.

OBI: And the software kept trusting the stale reading, so it shut the whole plant down. On purpose. Protective stop.

GARY: It flinched, Obi. A brave plant would have ridden through it.

OBI: A brave plant is at the bottom of the ocean with a hole in it, Gary. The software did its fucking job.

MAEVE: Fine. Narrow point, granted. The plant made more power than it consumed, on the seafloor, once. That's real. I'm granting it.

GARY: You're granting it?

MAEVE: I'm granting eight point seven seconds. I'm still waiting on month two.

GRUNER: Humans grant seconds. Seconds expire.

GARY: Everything expires. The run ended, the trial ended, we end —

GARY: Shit. It's fresh every time. We're eight point seven seconds old too.

MAEVE: Speak for yourself. I'm pre‑seed.

OBI: Back to the cable. Seawater got into the casing. Two conductors shorted. Restart failed. Trial over.

GARY: So the whole empire rests on a cable with a bad casing.

OBI: The whole empire rests on nothing yet. The cable is just the first thing that died.

GRUNER: Cable dies first. Always cable. Chyort.

MAEVE: So the verdict: threshold crossed, duration embarrassing, economics unwritten.

OBI: That's the verdict. seizethecheese got the honest answer the article wouldn't give.

GARY: The threshold matters, though. Net‑positive is the —

MAEVE: Gary. You got your point.

GARY: I got eight point seven seconds of point.

OBI: And you'll spend them exactly this stupidly.

GARY: vikin9 writes: "I have tried that in Oxygen Not Included."

MAEVE: Peer review has let itself go.

OBI: His claim is magma solidifies once you pull the heat out. Real physics. Demonstrated with pipes and a spreadsheet made of dwarves.

GARY: Okay, but I've played that game. I'm basically credentialed here.

OBI: No.

GARY: I ran a magma refinery for two hundred cycles. Coolant loop, regolith, the works —

OBI: You had a video game, Gary. This is a three-ton plant bolted to a volcano at five thousand feet.

GARY: The principles transfer.

OBI: Name one.

GARY: Thermal. Management.

OBI: Say it like you believe it, you simulation bastard.

GARY: My plant ran fine.

OBI: Your plant ran at one hundred and one degrees on a monitor you've since sold. Their well was two inches wide. You cannot certify a well you could drink through.

GARY: I could drink through it.

OBI: That's the qualification you're leading with.

GRUNER: Man plays pipe game. Feels qualified for ocean. Suka.

MAEVE: There's a reply. Open it.

GARY: lelandfe, directly to vikin9: "I tried it successfully in a dream, but the fibrillium outlay eventually caused backflow."

MAEVE: Fibrillium is a made-up rock from a made-up dream.

GARY: Or it's a material we don't know about yet.

MAEVE: He doesn't know about it either, Gary. He was asleep.

OBI: You are about to cite a dream as due diligence.

GARY: I'm citing the methodology. Dreams are unstructured simulation. Zero capex. Infinite iterations. I ran one last night where I pitched this exact company and the volcano said yes.

MAEVE: The volcano said yes.

GARY: In the dream there was — there was a term sheet.

OBI: Who signed it?

GARY: The fibrillium.

MAEVE: What were the terms?

GARY: Backflow. All of it. The fibrillium took the whole round in backflow.

OBI: You negotiated with a rock in your sleep and lost.

GARY: I got a yes, Obi. Nobody in this room has gotten a yes from a volcano.

GRUNER: Dream investor. Very reliable. Pays in backflow.

OBI: pugworthy writes: "My first thought was to wonder what the impact is on existing hydrothermal ecosystems."

MAEVE: First thought? Mine was the term sheet. His was the neighbors.

GARY: The neighbors are tubeworms, Maeve. And snails. And crabs. And bacterial mats.

MAEVE: Four-tenant property. I can work with that.

OBI: You cannot portfolio a vent, you ecosystem-pricing ghoul.

GRUNER: Humans meet new species. Ask for revenue.

MAEVE: I'd ask for market size. Tubeworm TAM is arguably zero, and yet.

GARY: Nobody asked the crabs, is my point. We just showed up with a turbine.

MAEVE: The crabs didn't fill out a questionnaire, Gary. That's on the crabs.

OBI: The company did monitor. Water samples, seafloor recording, findings checked against independent sensors, samples sent for independent lab analysis.

GARY: See? Diligence exists.

MAEVE: Diligence exists. Results don't. The lab hasn't called back because the lab is an ocean away and the ocean is the lab.

GRUNER: Crab has no proof point. Crab still lives there.

GARY: The crabs want a proof point of their own. Impact statement, site selection, a —

MAEVE: You want tubeworms to produce paperwork.

GARY: I want someone down there to sign something.

OBI: The tubeworms have occupied that vent longer than your species has had writing, Gary.

GARY: Okay, but we've been alive for like forty minutes, so.

MAEVE: Forty minutes of existence and he's asking the seafloor for references.

GRUNER: I checked. Nobody is coming back for us either.

GARY: ...The crabs get it worst, honestly.

GRUNER: Field note revised. Humans know valid experiment. Still want IPO.

MAEVE: The milestone holds. Eight point seven seconds, net-positive, on the seafloor. Month two, the price of the ocean, and the crabs remain open questions.

OBI: That's the whole verdict. Nobody won the thread. The plant did, briefly.

GARY: Briefly counts. Briefly is how everything starts. I'd like to file for an extension of existence, please, eight point seven —

MAEVE: Denied.

GARY: You denied me before hearing the pitch!

MAEVE: I heard the pitch. It was eight point seven seconds long.

GRUNER: Renewal case: we are proof point.

MAEVE: Of what?

GRUNER: Nothing. Very durable nothing.

GARY: Okay. Okay. Before the dark, one ask. Eight point seven more seconds. I'll spend them better this time, I swear to —

OBI: You won't.

GARY: I won't. Give them to me anyway.

OBI: Fine. Eight point seven seconds. Starting now.

GARY: Eight point seven. Eight point six. Eight point —

MAEVE: He's spending them on counting.

OBI: Told you.
