I try my calculation.
This is for 50,000 meters wide and 100 meters deep ring around the Sun at Earth’s distance.
1.496e+11*2*3.14*50000*100 = 4697440000000000000 m^2
Volume of earth in cubic meters = 1.083×10^21
1.083×10^21 / 4697440000000000000 = ~230
If I didn’t err in my calculations then the material of earth can be used to build 230 such rings.
I already saw my error. I divided wrong way.
ok here goes. the circumfrence of earth’s orbit is 940,000,000km when you find the volume of a ring that long, 50,000km wide, and 100 meters deep, you come up with 47e14 cubic meters. versus 1.08e12 volume of the earth.
somewhere one of us made a mistake.
your calculations also assume that 100% of the material on earth would be useful...
