On a more serious note, I'd love to find out more about just how much weight they think this tech could support in the future. Those implications could be insane.
Agreed. If the "floating" (I know its not actually floating in the traditional sense) object could carry its own light-weight cooling system then you wouldn't need to chill the entire unit to super cold temperatures. You might only need to cool the superconducting layer.
The thing is, we are all waiting for room temp superconductors. That paper on the Reddit post seems to have some breakthrough regarding this if I'm not wrong.
Loads of up to 500 grams on this test rig, on what look to be about n40 magnets, according to the presenter's comment on one of the lab videos. The liquid nitrogen is a problem but that payload seems like something that could already have industrial applications.
In the lab we succeeded in putting up to 0.5Kg on top of one disc. Keep in mind that the thickness of the superconducting layer is ~1micron ! Its a strong effect.
