Why you need to build planet-sized shield? Why not pollute top layers of atmosphere with something bright? SO2 will be good choice. One satellite with few tons of SO2 can pollute Venus atmosphere in few weeks, and it will stay polluted for thousands of years. |

There is already a crap-ton of SO2 in Venus's atmosphere (about 40 teratonnes, to be precise), that's where the sulfuric acid clouds come from. If we sent a supertanker full of SO2 to Venus every single day for a thousand years we wouldn't affect the amount of SO2 in the atmosphere by even 1%.
