200W from The Earth

200 watts!  That is the amount of energy that the Earth/Sun system is emitting as gravitational energy as they orbit each other - according to Einstein's theories of relativity.

When I say they 'orbit each other' of course I meant that the Earth goes around the Sun and the Sun wobbles a bit.  (See more in the Wikipedia article about gravitational waves.)

You could run a few light bulbs on that much power, but that is all.
