Philip, "Neville, what actually is the ratio of energy in to energy out from space, the sun of course being the major contributor." Radiated energy coming from the Sun is covered in "Stellar distances and the age of the universe" on www.midclyth.supanet.com We were talking of EXCESS heat caused by the friction of the atmosphere rubbing against a spinning World (as you do, in fact, concede that you don't accept anyway - "This is all academic of course, as it is to me highly probable, I should say certain ... that the world doe not spin, ..."). As for your, "Also for the same reason, why does the gyro of which the faucault pendulum is but a part, rotate one revolution per day with the sun," I cannot answer that question at the moment. Best wishes, Neville. Philip <joyphil@xxxxxxxxxxx> wrote: to an atmosphere which would heat up due to this friction and dissipate this extra energy by radiating most of it out into space. Neville, what actually is the ratio of energy in to energy out from space, the sun of course being the major contributor. I thought we were gaining heat. Perhaps it varies. As a part of the point you raised fluid versus solid cloak, couldn't there be a stable mean. a resultant of all the factors' This is all academic of course, as it is to me highly probable, I should say certain if I use that awful C word, that the world doe not spin, and neither does the atmosphere except in a cyclone. We should be looking for other reasons for the clockwise/anticlockwise rotation of cyclones and hurricanes....Also for the same reason, why does the gyro of which the faucault pendulum is but a part, rotate one revolution per day with the sun...
