I thought the problem with multiple wings is that the first one pushes air downward (to induce lift), and then the proceeding wings get caught in the downdraft.

I thought the problem with multiple wings is that the first one pushes air downward (to induce lift), and then the proceeding wings get caught in the downdraft. Just looking up pictures of planes with multiple wings, it seems like it's common to put the first wing at the bottom of the fuselage and then the second wing at the top. The theory being that the second wing will be above the downdraft and able to provide lift. Anyways it looks like this company is generally considered to be a scam so I don't think this is much more than a 3D render.

Biplanes do increase lift, but there's always tradeoffs. The main problem with them is the struts add drag, as well as two wings above each other. Some biplanes stagger the top and window wing, like the Staggerwing: https://en.wikipedia.org/wiki/Beechcraft_Model_17_Staggerwing https://en.wikipedia.org/wiki/Beechcraft_Model_17_Staggerwin...
