How to pronounce “h2o” in English

That's a game-changer. Now, this is frozen water.It's H2O. We drink it here, same thing.H2O on the moon is H2O.

had spoken about the benefits of NASA and the value of NASA uh to to public audiences before and there was stuff onof water of Simply H2O um and that would solve the problem

That's one of the US instruments from Alan Stern and SWRI.So this CO2 and H2O is being liberated subsurface and escaping through this extremely porous comet.

But how did we get from asteroid-pummeled planet to life-sustaining paradise?I got two words for you: H2O, baby.Water didn’t just appear one day out of the blue.

How did your view of cooking it and eating it change?It's only pulling out all the H2O from the braise itself.

And thank you, , for providing this excellent prop.I can tell you that there are about 4 cubic inches of H2O in this glass, and I can tell youthat there are 4 cubic inches of oxygen and hydrogen in this glass.

but fuels. This is sort of fuels from sunlight. It's actually a project that CalTech and Berkeley are working very hard on now. It's a great idea. The idea we want to mimica photosynthesis. We want to take CO2, H2O, simple, very simple molecules and with a photon from the sun produce alcohols; sugars, alcohols, ultimately even sophisticated drop inbiofuels like biodiesel. If you can do that at scale you'd have something important. And we can debate whether you can do that or not. So what I thought I would do is just

- Mostly that's just in water. Mostly it's a mix of, we call this actually heavy water, where you have normal water that you'reused to. We talk about and you learn in school, is H2O, where there's two hydrogens and oxygen in a nucleus in themolecule. And deuterium, or heavy water, is D2O, two deuteriums and an oxygen. In reality, it's actually an interesting mix where you have some

on their investment and help millions of people get access to water.And it didn't take too long to recognize-- Matt created a great organization, too, H2O Africa.

Then they throw the waste out into the street where it runs back down to the river and is carried away.Perfection. Unless you live in a city downstream from, say, London in which case your H2O is a veritable Petridish of living goo, courtesy of the folks upstream.

is because it actually breathes. The oxygen comes in, burns the lithium, and goes out again. You have to be able to have it go out again. By the way, the problem,that's a chemistry problem, breaking lithium oxide. It's the same chemistry problem or similar to the one I need to make CO2, H2O andsunlight into sugar. So there's a lot of commonality in fundamental science we have to solve to make these exciting things happen. So this will give you the energy

And, as a result, there was an immense amount of ice.But ice and water are what I call, "Playmates on a Seesaw.” And, when you have a lot of H2O tied up in ice, you have much less of it tied up as water.And so, when you have ice on the continents starting an Ice Age, you also have much lower sea levels. And, in fact, the ocean level at the height
