			=== Generating Electricity ===
			Fire produces heat, which can heat water until it becomes steam, which can power turbines, which can power generators, which will produce electricity. Alternatively, the turbine can be directly used as mechanical energy.

	Fire can be created through [[friction]] by rapidly grinding pieces of solid combustible material (such as [[wood]]) against each other (or a hard surface) which are heated and create an ember.		Fire can be created through [[friction]] by rapidly grinding pieces of solid combustible material (such as [[wood]]) against each other (or a hard surface) which are heated and create an ember.

	The [[hand drill]] is the simplest method, characterized by the use of a thin, straightened wooden shaft or reed to be spun with the hands, grinding within a notch against the soft wooden base of a fire board (a wooden board with a carved notch in which to catch heated wood fibers created by friction). This repeated spinning and downward pressure causes black dust to form in the notch of the fireboard, eventually creating a hot, glowing coal. The coal is then carefully placed among dense, fine tinder, which is pressed against it as one blows directly onto the coal until the tinder begins burning and eventually catches into flame. The advantage of the hand drill technique is that it requires no rope.

	The [[bow drill]] uses the same principle as the hand drill (friction by rotation of wood on wood) but the spindle is shorter, wider (about the size of a human thumb) and driven by a bow, which allows longer, easier strokes and protects the palms. Additional downward pressure is generated by the handhold.
