Jules Verne: Twenty Thousand Leagues Under the Seas

SECOND PART CHAPTER 16: Shortage of Air (continued)

Meanwhile, motionless and silent, Captain Nemo stood lost in thought. An idea visibly crossed his mind. But he seemed to brush it aside. He told himself no. At last these words escaped his lips:

"Boiling water!" he muttered.

"Boiling water?" I exclaimed.

"Yes, sir. We're shut up in a relatively confined area. If the Nautilus's pumps continually injected streams of boiling water into this space, wouldn't that raise its temperature and delay its freezing?"

"It's worth trying!" I said resolutely.

"So let's try it, professor."

By then the thermometer gave -7 degrees centigrade outside. Captain Nemo led me to the galley where a huge distilling mechanism was at work, supplying drinking water via evaporation. The mechanism was loaded with water, and the full electric heat of our batteries was thrown into coils awash in liquid. In a few minutes the water reached 100 degrees centigrade. It was sent to the pumps while new water replaced it in the process. The heat generated by our batteries was so intense that after simply going through the mechanism, water drawn cold from the sea arrived boiling hot at the body of the pump.

The steaming water was injected into the icy water outside, and after three hours had passed, the thermometer gave the exterior temperature as -6 degrees centigrade. That was one degree gained. Two hours later the thermometer gave only -4 degrees.

After I monitored the operation's progress, double-checking it with many inspections, I told the captain, "It's working."

"I think so," he answered me. "We've escaped being crushed. Now we have only asphyxiation to fear."

During the night the water temperature rose to -1 degrees centigrade. The injections couldn't get it to go a single degree higher. But since salt water freezes only at -2 degrees, I was finally assured that there was no danger of it solidifying.
