FUV is an electromagnetic device of 3 magnets, the interaction of which causes a partial effect of weightlessness in the earth's atmosphere and stratosphere. Operating principle: the numbering of the magnets is taken from the description of the invention. Magnet two is stationary and motionless, magnet three rotates around it, it is like a rotor. Between them is magnet number one and it seems to hover between magnets two and three. Which causes a partial effect of weightlessness. 90-99%. Note: the internal parts of the device in which the FUV is installed should not touch each other. attached to magnets two and three. since the effect of weightlessness will be lost. And it can lead to a short circuit inside the invention. The industry of FUV manufacturing is energy. Application area: aircraft construction. P.S If you are interested in this invention. And want to participate in its improvement. I can send you its data by e-mail. The invention requires professional calculations in physics with an energy focus. My e-mail: removed Write!!
