I seem to remember when I was teaching physics that the big winds of el Nino several years ago managed to extend the day by a few milliseconds (big lump of angular momentum in one direction reduced the angular momentum of the solid earth to keep the sum a constant). So, I suspect that it's a non-trivial task. :-) Or, we can just wait a zillion years and let the moon do it naturally. Kerry On 12/30/05, Henry Baker <hbaker1@pipeline.com> wrote:
Some radio wags have contended that it would be cheaper to fiddle with the Earth's actual rotation, than to keep screwing around with leap seconds. How much effort would it really require to speed up or slow down the Earth's rotation by one second in one year?
