It is a controversial proposal, but the experiments demonstrate. Earth rotation can be used to generate electricity. It would be from a device that interacts with the Earth’s magnetic field. Chris Chyba, from Princeton University, made a hollow magnetic cylinder to generate electricity using the earth’s magnetic field.
The cylinder does not move, but turns with the planet. The earth’s magnetic field drags it. 18 microvolts are generated through the cylinder when it remains perpendicular to the earth’s magnetic field. This finding is published in the Physical Review Research magazine.
Taking advantage of the rotation
Chyba was interested in the generation of electricity approximately a decade ago. Analyzed a warm -up mechanism in the moons that move through the magnetic field of a planet. He wondered if a similar effect could occur in earthly surface objects.
The magnetic force can be calculated. The electrons of a metallic object located in a Princeton laboratory, for example, move 350 meters per second through the local magnetic field of 45 microteslas. It generates a force per charge of approximately 10 millinewtons per culomium. But those electrons are rapidly reorganized on the metal surface. And create an electric field of 10 millivolts per meter that cancels exactly the magnetic force. How to force a pattern that cancels the magnetic force?
A situation without cancellation occurs in a hollow manganese-zinc ferrite cylinder. This material is both a magnetic shield and a weak conductor. It can accumulate a small voltage in the cylinder when placed correctly in the earth’s magnetic field. That was the idea that Chyba and Kevin Hand, from the Charifornia jet propulsion laboratory, proposed in 2016. The American Physics Association (PHC) reported.
Electricity in series
If the rotation of the Earth can be used, we can generate electricity. They expect an independent research team to try to reproduce the results. If confirmed, imagine that the configuration could be optimized for energy generation. Many miniature cylindrical components could connect in series to produce a useful voltage amount.
