And the story of the Intermittent Absorption Refrigerator.

No, Ammonia.

It's one of those things that stuck in my head.

Soon we'll arrive at Mizunashi Station.

Anhydrous ethanol.

200 pounds of ammonium nitrate fertilizer. I walked into my apartment...

No fish tank.

At Mizunashi Station.

Or we might try to synthesize fuel. We can configure it, not to produce electricity, but to dissociate water.

Farms, is an innovative waste management system.

And it was invented in 1858, by this guy Ferdinand Carre, but he couldn't actually build anything with it because of the tools of the time.

But just as a summary of that, the things that tend to get cited most often are the unrestricted submarine warfare, on the part of Germany, unrestricted... ...submarine... ...warfare, and particular cases are, the most cited example of that is the sinking of the Lusitania.

The submarine is irreplaceable.

It has to substantially eliminate emissions of ammonia, nutrients, pathogens, heavy metals, odors, and have zero discharge of wastewater to ground or surface waters.

You see, it wasn't a very good perfume.

That has a tang of ammonia about it.

Mind the electrics.

Water can not be had for nothing here.

Plants die without water.

Our city has no water service yet.

How many people times how much water.

Not even worth it.

And they use them, in the breaks, for water pistols.

There was no water in the well.

There wasn't any water in the well.

They collect 100 thousand liters in one season.

Knowledge today is a commodity.

On the lower left there is a picture of mother of pearl forming out of seawater.

My cousin Polle died because he could not get adequate healthcare.

He's not rescue diver material.

You can make ammonia out of hydrogen, which could be a fuel.

The flowers were dying without water.

We cannot do without water.

And you get water solutions. Water's one of the most pressing problems.

He sat up there and just died of thirst?

For all intents and purposes, there's not a drop of water that's wasted aboard.

How they planned to make it out of emptying reservoirs, that I don't know.

But this small village, germ of something more, why did it fail while Concord keeps its ground?

We have enough water for several years before replenishing.

Ammonia is a colorless liquid or gas with a very strong smell.

And then we give it a second gene to grow an inorganic material that can be used to split water into oxygen and hydrogen, that can be used for clean fuels.

Finally, if the flood goes away, we go from A to G.

Water, water, water.

And the reason we know this is that the gas is not pristine.

But by now, everybody agrees that the elephant had an aquatic ancestor.
