How to Make/Build a Lifter or Ionocraft

I realize I'm going to sound absolutely bonkers, but I definitely read an article in Wired about devices which used very large amounts of electricity to hover feet in the air. They were triangularly shaped, built in garages, used aluminium somehow, and could hover in the air. I really wish I could find a link to that Wired article... Edit: Found it! [link] Edit2: Doing some research (it's coming back to me now), it runs off of ionic wind, which is apparently a well understood phenomena. I'm guessing this was/is being thoroughly researched, and any outcomes have apparently not been fruitful (yet?). I realize I sound bonkers, but come on, this is pretty cool, even if nothing of value has resulted. [link] Guy explains it pretty well: ▶ this video

These were popular decades ago, and were the focus of many an argument over the basis in theory of how they worked. Many did not understand that they depend on atmosphere to operate. ▶ this video

The gas collecting portion of this design wouldn't work well, but it's certainly possible to generate thrust by ionizing air at atmospheric pressure and zero relative velocity. See [link] and ▶ this video
