Drunken argument...

Two drunks are walking along. One drunk says to the other, "What a beautiful night. Look at that moon!"

The other drunk stops and looks at his drunk friend. "You are wrong. That's not the moon; that's the sun!"

Both continued arguing for awhile when they came upon another drunk walking along. So they stopped him and said, "Sir, could you please help settle our argument? Tell us what that thing is up in the sky that's shining. Is it the moon or the sun?"

The third drunk look at the sky and then looked at them and said, "Sorry, I don't live around here."

He summarized the natural sources of energy as Tides, Food, Fuel, Wind, and Rain. All except the tides derive energy from the sun. “Heat radiated from the sun ... is the principal source of mechanical effect available to man.” He referred to tide mills, and the possibility of storing energy in batteries between tides, but nevertheless considered the economics impractical for wide application. Windpower he considered “decadent,” but acknowledged coal would become an exhausted resource, thus windmills should generate electrical power. Kelvin also outlined the economics of hydroelectricity.«
