Here is an excerpt from the article:
"Here is how it works: Electrodes lining the vehicle's surface ionize the surrounding air. This creates plasma on the vehicle's exterior. An electrical current sent through this plasma generates a force that not only produces the necessary lift and momentum. It also stabilizes the vehicle in windy conditions. "
I can not figure out what kind of mechanism is involved here. Here is the whole article:

If someone can explain how this thing works, I would love to hear it.
