rotational kinetic energy

Maybe the sun is spinning down, is slowing down and maybe the energy that we get is nothing but rotational kinetic energy.

I will first discuss with you the sun and the earth and see how much rotational kinetic energy is stored in the earth and in the sun.

If I know the moment of inertia, then I know how much rotational kinetic energy there is.

All that energy is at the expense of rotational kinetic energy.

Now, they use this rotational kinetic energy to create very strong magnetic fields on a time scale as short as five seconds.

Obviously a physical pole shift would have enormous climatic and tectonic consequences with tremendous changes in rotational kinetic energy.

So you should also be able to get the rotational kinetic energy out and convert that again into forward motion.

And this rotational kinetic energy can then be, perhaps, converted into electricity or in other forms of energy.

And the rotational kinetic energy can be consumed, then, at a later time, so it's very economical.

then, you would have consumed up all the rotational kinetic energy and then the earth would no longer be rotating.

And when the traffic light turns green, you convert it back rotational kinetic energy into linear kinetic energy and you keep going again.
