Terraforming Venus
Gene P. a écrit :
I was thiking about terraforming Mars, and how most such schemes call for big solar mirrors to heat the surface a bit. well for Mars , the first thing to do, I think , is to keep the heat from the sun better than bringing more radiation power greenhouse gas could be produced and maybe much more efficient to raise planet temperature ... I think this is something realistic think that the "sky temperature" above atmosphere is about 3K (-270C) so shielding a bit to prevent radiation losses would probably give good results within decades or centuries mirrors may be useful to light or heat spot areas. I think I read about 'today s project' to use mirrors to replace night street lights and so... it would use inflatable reflective structures and beam light localy ... it would be like a few full moons together .. would not prevent you from freezing on a parking lot , on a winter night .. Venus has the reverse problem... WAY too hot. How much sunlight would have to be blocked to break the greenhouse loop and reduce temperatures into the earthlike range? don t remember well , but I think anything conceivable to change Venus meteo is a matter of thousands/millions years , so Venus ... |

How much sunlight would have to be blocked to break the greenhouse loop and reduce temperatures into the earthlike range? This is far from the only problem. We would also have to get rid of a huge portion of the atmosphere, most of which will not condense out even at Martian temperatures. -- This address is for information only.

According to http://www.paulbirch.net/TerraformingVenusQuickly.zip, you can do it a matter of decades. -l. ------------------------------------ My inbox is a sacred shrine, none shall enter that are not worthy. |
