Thesta distatica methernitha and several other free-energy devices.

1. Thesta distatica methernitha is a free - energy electrostatic machine based on Wimshurst machine and was build by Paul Baumann in Linden near Bern in Switzerland. The device belong to Methernitha, a small christian community in Linden founded in 1960. The device was presented 30 times to researchers in 1999 however the community never admit to solid checking of the device to scientists, to unveil the secret of operation of this machine.

2. Coler coil is a permanent magnets based free-energy device designed by Hans Coler and it is generating electric current from static magnetic field of permanent magnets using coils and capacitors.

3. N-machine was invented by Bruce De Palma and it is a machine using a telekinetic effect from slowing down the magnetic field by centrifugal force what makes electron to generate additional electric power and that should makes the system in assumption over-unity device. Citation from the site about Bruce Depalma ( https://brucedepalma.com/ )"The DePalma generator is essentially a simple magnetized flywheel. His astonishing claim is that the present version of the N machine can generate up to five times more power than it consumes. This, of course, defies the basic law of the conservation of energy, which says that the output of energy cannot be more than the input. Most physicists simply refuse to look at DePalma’s findings and dismiss his theories out of hand."
