However the appeal of the book was less in the text but instead in the fantastic illustrations by Chesley Bonestell, who places the reader in a rocket ship, looking down on the Great Lakes from miles above; standing on one of the moons of Saturn looking up at a view of that glorious world; or passing Halley's Comet in a spaceship in ! They are just a few examples.

January 31, 9: They power everything from passenger vehicles to delivery trucks to bulldozers to trains to ships. Diesel engine is an internal combustion engine that converts chemical energy in fuel to mechanical energy.

It is the mechanical energy that moves pistons up and down in the enclosed spaces called cylinders. These pistons are connected to the crankshaft, whose movement switches from linear to rotary to propel the wheels. As the fuel reacts chemically with oxygen, a series of small explosions occurs, releasing energy.

In a diesel engine, the fuel ignites on its own. After the piston swings upward, the air is compressed and heated.

Before the piston reaches the top of its compression stroke, the fuel is injected under high pressure and then ignites spontaneously upon contact with the heated air. Gasoline engines, like diesel engines, work by internal combustion. They have slight differences, though.

A piston compresses squeezes the mixture, making it explosive, and a small electric spark from a sparking plug sets fire to it.

Woodford notes that theoretically the gasoline engine, with its spark plug, should be more efficient than the diesel engine. The reality is different: It is the diesel engine that is substantially more efficient than the gasoline engine.

One reason is that the fuel is easily compressed in the diesel engine because it requires no sparking-plug ignition system.

The fuel that diesel engines use also gives them several more advantages. Diesel fuel, which Mr. Woodford described as a lower-grade and less refined petroleum product made from heavier hydrocarbons, contains more energy per gallon because the molecules have more energy locking the atoms together.Explain that Stuff is an online book written by British science writer Chris Woodford (author of many popular science books for adults and children.

That makes the mixture explode, generating power that pushes the piston down the cylinder and (through the crankshaft and gears) turns the wheels,” explains Chris Woodford, a British science writer who runs the Web site Explain that Stuff.
