Electrogravity educational set
I did an research on a phenomenon, we built some devices for our research, they was electrohydrodynamic (EHD) devices (utilizing an electrical phenomenon known as the Biefeld–Brown effect) to produce thrust in the air, without requiring any combustion or moving parts. This phenomenon is utilized in B2 aircraft to improve trust energy.This device is a propulsion device based on ionic air propulsion that works without moving parts, flies silently, uses only electrical energy and is able to lift its own weight plus additional payload, with the future prospect of its power supply. The principle of ionic wind propulsion with corona-generated charged particles has been known as from the earliest days of the discovery of electricity, with references dating back to 1709 in a book titled Physico-Mechanical Experiments on Various Subjects by Francis.(Wikipedia).
