Now, consider that the Earth is rotating. It has kinetic energy of rotation. It is known to have a rotational inertia of 8.01 * 1037 kg-m2. It rotates once a day, so it turns at the rate of 6.28/86400 radians/sec. The Earth's kinetic energy of rotation is (I) the rotational inertia * the square of this rate, or 4.231792 * 1029 kg-m2/s2. Now say that the Earth's rotation somehow SLOWED by ONE SECOND per day. Instead of a day being the current 86400 seconds, it would then be 86401 seconds long, an absolutely unnoticeable effect. The kinetic energy calculation above would be the same except we would now use 86401 and the Earth's kinetic energy would be 4.231694 * 1029 kg-m2/s2. A basic law of Physics is that energy must be conserved. By slowing down by just that single second, an unnoticeable effect, and one with no consequences whatever, the Earth would have had to have given up the difference in those two energy totals, or 9.8 * 1024 kg-m2/s2, or 9.8 * 1024 Joules. A Joule is a watt-second. To convert this into kWh, just divide by 3600 seconds/hour and 1000 watts/kW or 3.6 million, and get 2.7 * 1018 kWh. See my reason for fascination? If someone could figure out how to tap into this enormous energy of rotation of the Earth, to somehow convert a tiny part of it into electricity, we could totally supply all the electricity needed for all American homes for 2.7 million years while only making the day one second longer. No burning of coal, oil or natural gas to deplete those supplies or pollute the atmosphere with their waste products and their global warming. All the known supplies of oil, coal and natural gas together will probably be used up in only around 100 years. And then what? IF somebody can figure out how to convert that rotational energy of the Earth, WOW! Even a conservative view makes clear that there are billions of times as much energy present as we could ever hope to discover in all the coal and gas and oil we will ever find.
