My invention is a device which reacts to thoughts of people at distance, without any sensors on the head. The device switches on and off any electronic device, for example a light-emitting diode, remotely, from the mental command of the person, at distance, without any sensors on the head. My idea consists that Josephson tunnel junction with a certain thickness of dielectric between conductors and with a certain area of junction can react to thoughts of people at distance, switching on and off any electronic device, for example a light-emitting diode, from the mental command of the person at distance. The principle of operation of the device is based on influence of mind on tunneling of electrons. I opened that under the influence of human mind, electrons can pass more or less through a thin layer of the dielectric being between conductors in Josephson tunnel junction closing and disconnecting contact from the mental command.
