Odyssey with Grok Imagine

A San Francisco startup says it just turned mercury into real gold, and their own math says gold is one of the cheapest things their machine can make. Aim it at a different metal and it makes a cancer drug ingredient worth tens of billions of dollars a gram.

Here's how it works. When you fuse two kinds of hydrogen, deuterium and tritium, every single reaction kicks out a neutron moving at 14.1 MeV, which is absurdly fast. Fire one into mercury-198 and it knocks another neutron loose on the way through, so two come out and you're left with mercury-197. Give that a few days and it decays into gold-197, the only stable kind of gold there is. The whole trick needs neutrons above about 6 MeV, and regular nuclear reactors barely make those, while fusion makes one every time it fires.

Now swap the mercury for radium-226. Same reaction, one neutron in and two out, and you end up with radium-225, which decays into actinium-225. Novartis is building its next prostate cancer drug around actinium-225, and it's so scarce it sells by the millicurie, roughly $1,200 to $2,500 apiece. Price it by the gram and you're into the tens of billions of dollars, for a material so radioactive nobody could safely hold a gram of it anyway.

Marathon's team actually put a dollar value on a single fusion neutron in a paper this year. Use it to make electricity and it's worth about $3 × 10⁻²⁰. Gold comes in at $2.6 × 10⁻²⁰, basically a wash. Molybdenum-99, which goes into about 80% of nuclear medicine scans, is worth $2.6 × 10⁻¹⁷ a neutron. Actinium-225 is worth about $10⁻¹⁰, around 3 billion times what the electricity's worth.

That's why fusion people should care. Every fusion company you've heard of is chasing electricity, and selling electricity only pays once the plasma puts out something like 10 to 22 times the energy you pump in to heat it. The best result so far, at JET in England, was about a third. Add gold on the side and Marathon's math says you break even around 3x. For molybdenum-99, the number is 0.001x.

So a machine that gives back one-thousandth of the energy you feed it can still make money, as long as the neutrons hit the right metal.

By their numbers, a 3 megawatt machine running way below breakeven could cover the whole world's supply of molybdenum-99, which today comes from splitting uranium in a handful of research reactors. Today's experimental fusion machines already beat the gain that job needs.

Their second post basically says this out loud. Marathon now describes itself as an isotope company for radiopharma. Their chart shows roughly 390 targeted radiotherapy trials. Pluvicto, the prostate cancer drug Novartis launched at $42,500 a dose, did $1.9 billion in sales last year.

Gold still matters to them, just later. It's about a $700 billion a year market, and Marathon's paper figures it could soak up around 2 terawatts of fusion capacity, which is roughly the scale where fusion actually moves the grid. So the plan is to sell cancer isotopes out of small machines now and use gold to pay for the giant ones, years before electricity can pay for itself.

🚨 BREAKING: Elon Musk just pledged to give one of his own SpaceX shares to EVERY child in America next year, a gift worth about $10.5 BILLION

PATRIOT 🇺🇸 👏🏻

"Next year, I will give one of my SpaceX shares to every kid in America. This will be the first of many."

There are just over 72 million Americans under 18, and SpaceX closed Friday at $146.03 a share

It's also not the first gift like this from SpaceX. In July, COO Gwynne Shotwell pledged one share to each of 2 million Trump Accounts

Elon is putting his money where his mouth is!

We don’t deserve him 🙏🏻

Delhi Police has a weird habit.

First, they detain you and deny you access to lawyers the entire time. They don’t tell you or anyone where you are being taken to.

Then, at 3:30 in the morning, they suddenly show up with arrest papers and finally call your lawyer at 4 AM!

This has happened to me twice now. Ye 3:30 AM ko aisa kaunsa shubh muhurat hota hai, Delhi Police?

Elon Musk explains why charging your EV to 100% on a road trip is a mistake:

On a road trip, your instinct is to fill the battery all the way up.

That's how you'd treat a gas tank.

But a battery doesn't work like a gas tank.

Charge to about 80%. Drive it down to 10% or less. Repeat.

This is just for long trips, when you want to spend as little time at the charger as possible.

Elon: "Getting from 80 to 100, it takes about as much time as getting from 0 to 80."

The reason is what's happening inside the battery.

Lithium ions travel from one side to the other, looking for a place to settle.

Think of them as cars hunting for a parking spot.

When the lot is empty, they zip right in.

As it fills up, they have to circle around, like at a packed mall.

So the closer the battery gets to full, the slower it charges.

The last few spots take the longest to find.

We live in a country where every good innovation is treated like a scam.

Crypto? A scam.
Starlink? Stealing our data.
Self-driving cars? Killing jobs.
Robotics? A threat to the economy.
AI? Taking away jobs.
Prediction markets? Gambling.

Meanwhile, people in the US are building businesses, making money, and using these technologies to improve their lives.

Instead of finding ways to regulate and adopt good technology, we keep finding reasons to reject it.

You can't build a future by being afraid of innovation.
