"Figure 5 shows a form of the apparatus for separating a liquid from another of different boiling point, such as alcohol and water. The mixture is poured into retort B, and then heated to about 90 degrees C, which is above the boiling point of alcohol but below that of water. The vaporized alcohol escapes through A to the worm D. This is a simple helical coil of pipe surrounded by cold water, and serving to condense the vapor, which runs out as a liquid at the bottom. The cooling water is constantly changed by the supplying fresh cold water at the bottom and drawing off the heated water from the top." Louis Derr, 1911

"Steam is admitted under pressure for a boiler into a metal cylinder behind a piston, as represented in figure 14. Its pressure drives the piston forward, doing useful work. When the piston has moved through a part of its stroke the steam supply is cut off, the stroke is completed by the expansion of the steam confined in the cylinder. By the first law of thermodynamics this expansion cools the steam, since work is done in the process; but the expansion is not adiabatic, since the cylinder and piston give up some heat to the steam within. At the end of the stroke the exhaust valve opens and the cooled steam escapes into the atmosphere or condenser through exhaust pipe A. The operation is then repeated on the other side of the piston." Louis Derr, 1911

Then answered all the people, and said, His blood be on us, and on our children." Matthew 27:22-25 KJV

"And Moses stretched out his hand over the sea; and Jehovah caused the sea to go back by a strong east wind all the night, and made the sea dry land, and the waters were divided. And the children of Israel went into the midst of the sea upon the dry ground: and the waters were a wall unto them on their right hand, and on their left. And the Egyptians pursued, and went in after them into the midst of the sea, all Pharaoh's horses, his chariots, and his horsemen. And it came to pass in the morning watch, that Jehovah looked forth upon the host of the Egyptians through the pillar of fire and of cloud, and discomfited the host of the Egyptians. And he took off their chariot wheels, and they drove them heavily; so that the Egyptians said, Let us flee from the face of Israel; for Jehovah fighteth for them against the Egyptians. And Jehovah said unto Moses, Stretch out thy hand over the sea, that the waters may come again upon the Egyptians, upon their chariots, and upon their horsemen. And Moses stretched forth his hand over the sea, and the sea returned to its strength when the morning appeared; and the Egyptians fled against it; and Jehovah overthrew the Egyptians in the midst of the sea." Exodus 14:21-27
