As the fuel now, deuterium is also found in all water on Earth, in the water I'm drinking right now.

It's in my body.

It's in Coca-Cola.

It's everywhere.

And safe and clean and one of those fundamental particles that was born in the cosmos.

And we estimate that in seawater here on Earth, we have, if we powered at our current use of electricity...

all of humanity on fusion, somewhere between 100 million years and a billion years of fuel in hydrogen and deuterium here on Earth.

And mostly that's just in water.

Mostly that it's a mix of, we call this actually heavy water, where you have normal water that you're used to.

We talk about, and you learn in school, is H2O, where there's two hydrogens and oxygen in a nucleus in the molecule.

And

And deuterium or heavy water is D2O, two deuteriums and an oxygen.

In reality, it's actually an interesting mix where you have some HDO, so a mix of hydrogen and deuterium.

You also have other hydrogenic species.

Tritium is another one where you add a second neutron to that hydrogen, and then you can have T2O, tritiated water.

And that's something that comes up and we need to talk about at some point.

And there's other, as you go up the periodic table, you get, add two protons and you get helium.

And so helium, the most common helium is, is helium four, which is two protons and two neutrons.

And then we use an isotope of helium.

The nucleus is called the helium, which is what we based the company after, which is two protons and one neutron.
