     A simpler and more controllable method of terraforming Venus 
would be to shine more sunlight on it and boil the atmosphere off.
Let us say you wanted to raise the temperature by a factor of 4.
This requires 64 times as much incident intensity.  Assume that
this is gotten from solar sails in Venus vicinity.  They need a 
total surface area of 7.24 billion km**2.  If their thickness is
.15 microns, then the volume of material required is only 1.1 km**3,
not an unreasonable quantity.
