We do that now. It is called wind-power and, to a lesser degree, hydro-electric power. Weather and water flows are all created and/or influenced by the rotation of the earth.

I think power = electricity. It is very interesting question. You are moving along the earth's rotation. If you are able to stay in the space in a permanent place, you can attach an armeture to the rotational axis of the earth and you can generate energy. But you are on the earth's surface and moving along the earth's rotational path. I can explain you in other way. Assume, you are sitting in a revolving chair. Can you rotate your self without touching the floor with your leg or without touching near by stable objects? The answer is NO. Like wise, if you are able to stay permanently in the space, you can generate power from the rotational movement of the earth. This answer is because as you asked about the power generation. But in nature, climatic changes are occuring in the earth due to earth's rotaion. From this climatic changes also we can generate energy. Eg. wind energy.

Assuming for the moment that you could construct some device to generate usable energy from the earth's rotation, this would result in slowing down the earth's rotation. Eventually, if it stops, there would be no diurnal variation. In other words, with the earth orbiting around the sun without rotating on it's axis, a full day/night cycle would be 1 full year instead of 24 hours. You would have 6 months of daylight and 6 months of night-time.

Tides caused by the rotation of the earth are used to generate power in a few places (France is one I believe)

Great idea. Now all we need is to construct something that isn't attached to the earth to receive the power. Because if it's attached to the earth, it's part of the same system and the motion will negate.

energy cannot be created nor destroyed, it could only be converted in one for to another... With that in mind, if you want to harness the energy from the earth rotational forces, you must be able to slow down the earth's spin. The difference in energy can be converted to usable energy for work.

The magnetic field must be moving relative to the generator to generate a current. Some experiments have been done in this area, but the return is rather small.

You mean somehow harness the rotation? Set a wheel on the ground and see how much it rotates, Einstein!

Because you have to slow the earth down in order to harness the energy.

how about this one
someone needs to invent a de-humidifier
that when the moisture is extracted from the air can be turned into drinking water!!!
