I missed seeing the He3 reservoirs on Mars.
Who said there was or wasn't?
And I also missed the mechanism where you can bring things from space to earth at a reasonable cost.
Gravity. Once we have a moon base, dropping payloads down to earth only requires heat shielding and parachutes. Cheap.
All these years I was laboring under the misapprehension that the moon rocks were expensive because it cost so much to get them.
That will remain true until we have a platform outside of the Earth's gravity well. Then costs plummet.
You were the one who said He3 was available in space. So where is it?

If this were true (which it's not), then why doesn't the moon fall on us - serious question? In earth orbit is NOT out of the earth's gravity well (obvious, because it it weren't in earth's gravity it would go sailing off.) The moon is in earth orbit, so even to get to the moon, you have to fight earth gravity all the way intil you hit the balance point between moon gravity and earth gravity and then you have to match moons orbital velocity. To get back to earth you have to overcome moon gravity and overcome the orbital velocity. If you just get it off the moon it will go into earth orbit. All of you science fiction fans forget that earth gravity is not the only thing that you have to expend energy on. There is solar gravity and orbital velocities too. LOTS of energy required for these.
