Reply to comment by i_should_be_coding in Would building a Dyson sphere be worth it: We ran the numbers. by filosoful

Assuming a 1 AU sphere for the original design spec, and assuming you want statites, then your target areal mass is around 1.6 g/m^2 .

Taking my 10% coverage estimate, the factored surface area of a 1 AU sphere is 2.81e22 m^2 or 4.5e19 kg of material. 2% of the Belt, assuming every rock is made of aluminum.
