Re: Existing Helium-3 market could finance lunar elevator today Everett, I think the 3 to 5 meter asteroids offer several advantages to the 50 to 100 meter. First there would be far less opposition to moving a 5 meter

Re: Existing Helium-3 market could finance lunar elevator today 8 to 40 trillion to build a lunar space elevator? That seems on the high end, I could see 800 million to 8 trillion, even then I would guess on the lower end.
