A test with my 2004 Coanda effect thruster.
The centrifugal pump on top blows a jet of air over the curved surface of the disc. This causes a drop of air pressure on top of the disc. The engine used here, is a cheap one from a small vacuum cleaner. As you can see, it gives about 288 grams of thrust. The engine uses 652 watts, so that's only 0.44 grams per watt. That's not enough to lift its weight, but enough to push a little car, as shown in this video.
