EDIT: My math was totally wrong. 10 trillion dollars, 0.1x world GDP. (Still a lot of money though) Leaving the old text below so the replies make sense. ---

To move 6,000,000 megatons of fuel into low earth orbit would take 111,111 Falcon Heavy launches, at a total cost of $10,000,000,000,000 dollars. (10 quadrillion dollars, 93x world GDP)
Something that takes the total global economic output of the planet a century just to lift the fuel into orbit doesn't read as plausible in the next 50 years to me.
- mozumder 10y agoYou wouldn't gather that fuel from earth.. you'd gather it from an icy asteroid or comet or moon (Europa).
- TurplePurtle 10y agoI'm not sure if your error is in the number or in the words, but the number you wrote down is 10 trillion dollars.
- DenisM 10y agoNote to mention that Falcon Launches would get significantly cheaper if we have to do 100,000 of them.
- sbierwagen 10y agoOops.
