quote:Originally posted by UltimaPlus with the whole Earths magnetic field thing.... Im sure conservation of energy would have something to do with stopping that??? wouldn't the orbit degrade or something..? and how would you get all that energy back down to earth?wOw the world spins?
quote:Originally posted by gsmollinThis is about greenhouse gasses? Then you are right, they need to be incorporated into the earth. AS it turns out, atmospheric CO2 can be burned into carbonate form, and the reaction is exo-thermic. There has been atleast one proposal to do this, as a power generation device. I could probably find the original reference for you, if you are really interested.
My idea is to make a disc of mostly gold and some mercury, and either between the moon and earth, for an experiment, or beyond the lunar orbit, to spin it extremely fast and release it before the sun to cast a shadow on the earth, so it would orbit the sun. If it is beyond the moon. And it if shaped right would expand hopefully to Lunar diameter...
Do you have any idea what it costs to launch something into space?
I thought gold and maybe the alloy was more ductile than that.
The correct term is "malleability", which is the ability to be stretched in a big foil, while "ductility" means the ability to be stretched in a long thread.

The word malleability refers to hammering , rolling or beating (from the latin word '"malleo" - "I hammer") into shapes - like bowls, sheets or foils. Ductile (from the latin word "ducare" - "to lead") refers to stretching - wires or sheet, for instance, if you spin a disc and make it stretch.
