If my understanding is correct, Global Warming occurs because Co2 content in the atmosphere prevents sunlight from being reflected back into space.So if we put a 2 mile reflector satelite in orbit (say above the arctic) for a given period of time, wouldn't that do the trick?Because the circumfrence of the shadow it would project would be exponentially increased by the distance from earth that the satelite was stationed.So it would be like creating an artificial eclipse to give the arctic a chance to refreeze itself without being struck by too much sunlight.Does that sound feesible?
We need to CONTROL friction. We spend just as much time trying to increase it as to reduce it. Examples of increasing friction include rubber soles and tyres. Nails. Rough surfaces. Sticky tape. Knots. Crimping. Bolts. Ice skates in the sideways direction. And so any more. We increase friction when we wish to reduce, or prevent, the relative movement of two objects. i.e we want things to stay where they are put. So the corollary is that we reduce friction when we want two objects to move relative to each other. A piston in a bore, Ice skates in the forward direction. and roller skates similarly. The axles of wheels. Teflon coatings. In every case the object is to lessen the amount of energy needed to maintain the relative movement of two objects.
In real life go around, for the test go straight over.
