Viscous heating in the Earth interior

[David Jonsson]

Hi

How much of the heat in the interior of the Earth is due to viscous
heating from tidal reshaping? It should be much more than other
heating sources. If we assume a stationary conditions then an estimate
could be done. Integrate the angular torque from the sun and the moon
and multiply it with the rotational speed. What does it give?

Judging by the extreme importance that global heating is being given I
think it is very reasonable to ask for this calculation.

I hope I don't have to do it myself. That would surprise me.

I saw some sites giving the deformation in the meter scale. Since this
approaches the precision of global positioning satellites I think the
subject must be given more attention.
