I beg to differ. It created a magnetic field that was strong enough to counteract gravity locally - for objects susceptible to magnetism. If you'd dropped a piece of plastic into the system, it would have fallen right through. (OK, I have actually seen that same experiment carried out with a small piece of (non-magnetic) lead - but that lead was so cold, it approached superconductivity, and things get interesting there. The guys at the Niels Bohr institute of physics sure have some fun toys.)

Still, supporting a piece of metal by a magnetic field is not substantially different from supporting it by a table.

The culture back then was one of machoness and a cowboy of the wild west. If I do.. so be it. That would never fly today.
Not sure the costs would be that much higher, but like with the original program, they would be very high indeed. And it would be silly to just replicate Apollo - we would want to add to the missions. Longer stays, harder-to-reach landing sites, that sort of thing.

Personally, I find the idea a bit anticlimactic. There's not much there, and it's at the bottom of a gravity well that's a pain to get into and out of. Now, a robotic Mars sample return mission - or better yet, half a dozen of them. Or a manned mission to a near-Earth asteroid.

The 'effects' were toroidal as well with that experiment.

Yes Ive heard that once room temp superconductors become practical, thats when we will start to see real anti gravity technology seen in sci fi movies, like hovering cars, buildings, even cities.
