Drive a shaft into the earth at the north pole and use its rotation to power a huge dynamo. It's so obvious. It would only mean tipping the dynamo on end so its axle was vertical. Or you could use gears even. Having read through the thread: Bill, You need something else to tie the dynamo to. Jim, the size of the earth that matters is the cross-sectional area. Oh hang on, that's what you mean isn't it? Yes (ignoring other effects). I couldn't see where the value had come from so was wondering if someone had assumed it was 'half the surface of a sphere' instead of the projected disc area.

Yes, that's why it's so much eaier to carry a sheet of metal with the edge facing downwards instead of the surface... Or to put it another way, the sun is mych deeper than the moon. Well why do we bother with tidal flow power generation then? Why not go to the source? Drive a shaft into the earth at the north pole and use its rotation to power a huge dynamo. "Give me a place to stand and I will move the earth" - Archimedes. Perhaps you could attach the dynamo body to the lumeniferous ether, it's supposed to be quite rigid. What you really want is a big crank pivoted at one of the poles, with the other end attached to the moon. -- Richard |

Apart from the irrelevance of size (angle subtended), this is also the wrong question as far as tides are concerned. The sun weighs about 27 million times as much as the moon, and is about 400 times as far away, so its gravitational attraction on the earth (M/r^2) is about 170 *greater* than the moon's. But the size of the tide is not determined by the strength of the gravitational attraction, but by the difference in that attraction on the near and far surfaces of the earth. That difference varies as 1/r^3, and that is why the sun's tidal effect is *less* than the moon's. -- Richard |

There are indeed exceptions, but I tire of dreadful science/environmental reporting by people too ignorant, too politically correct, or just too doctrinaire, to ask tough and important questions. Or just come out with completely incorrect statements and not over particulary techincal or complex subjects either. Things that I consider to be "general knowledge". They repeat and reinforce dogma. "Diabetics cause the disease by being fat and they make themselves fat by eating fat" Er no, insulin resistance causes some people to become diabetic, some people to become fat and some people to become fat *and* diabetic. This is caused by eating excess carbs. Not to mention Type 1 diabetes, LADA, MODY and other genetic forms, none of which are connected to overweight. Oh and no-one's life has EVER been saved, just *prolonged*. Well there was that Jesus guy once, allegedly, but the spin doctors may have got at that story |

Why is it that they don't seem to be able to operate stable democracies? Is it a racial characteristics issue, or merely that they have no tradition of stability and society? I know the former possibility can't be discussed thanks to PC fascism but a few free thinkers like myself are prepared to consider such ideas. Not a few of their Leaders were trained in the UK, Eton and Sandhurst come to mind They learned how to impose their tribal loyalties with modern weaponry from the Normans |
