Can Earth rotation electricity be created? Physicists divided a questionable idea
Experiments can help you take advantage of the energy of the Earth’s rotation of an unusual magnetic material. But it’s not all convinced

Electricity can be created from Earth’s energy, through its own magnetic field, according to a provocative claim presented by physicists this week.
Discoveries are controversial but intriguing, researchers said Nature. The effect was only identified on a carefully carved device and only 17 microovolta. A single neuron is part of the voltage when fire makes, other effects are not affected by observations.
If the phenomenon could be real and the device could be scaled, it can cause no spilling power while static, which can be useful in remote locations or medical applications. The authors published findings Physical review Research And he presented Anaheim, California, at a meeting of the American Fisical Society.

“The idea is somewhat intuitive and Faraday argued,” says Paul Thomas, the emeritus physicist at the University of Wissersin-Eau Claire. But experiments directed by Christopher Chyba, the physicist of the Princeton University of New Jersey, has carefully added. “I find it very persuasive and remarkable.”
Others agree that the results are striking, but they are skeptical. Rinke Wijngaarden, University of the Free University of Amsterdam has continued the affirmations of the authors since 2016 Failed to find influence in 2018 in his experiments. It seems very interesting to work, but “still” is sure chyba theory et al. cannot be correct. “
Planet Power
In theory, the device would operate in a similar fashion in front of an electric power plant, in which a conductor is moving through a magnetic field to move electrons, creating a current. As the land rotates and part of its magnetic field is static (at least According to a 1912 proof), his surface director would move through some components of the area.
Usually, this would not create a current, such as the earth, the electrons would leave electrical force, after all, the creation of static positions (does not apply to where the force of a conductor is constantly changing).
But Chyba and his colleagues said they found the gap. Using a complex calculation, when certain materials are in the form of unusual properties and cylindrical tube, the magnetic field of the Earth could become a strange configuration. This, they argue that the electrostatic force inside the device could not be canceled, creating the current.
To show their theory, researchers designed an empty cylinder with a gentle magnetic material with manganese, zinc and iron. While they were controlling for other effects, they searched the stress and current across the device. The results have verified their predictions: they saw a small μV voltage that depended on the orientation of the Earth’s magnetic field. The tension was zero when they used a strong part of the conductor than an empty tube.
“The observed tensions are so small,” Says Wijngaarden, but he stated that the Chyba’s team “went to great lengths,” to prevent other effects that imitate the phenomenon “, such as temperature variations.
Verification is required
More evidence is needed before anyone who really achieves the tension of the earth’s rotation, Wijngaarden says. Physicists can test the experiments in different latitudes that gives different results, as it suggests predictions. These comparisons would not be easy, but seeing amazing results, “they really need it,” he says.
If another team has verified the results, Chyba says the next step is to test enough device and scaling enough energy to create a useful amount of energy. “Our equations show how such a scale can be made, but that is very possible to show,” he noted.
Even if it works, the method will not create energy from thin air. He would touch the kinetic energy of the earth and do so, it would cause slowing the planet’s rotation over time – even if it was somewhat. If the technique has given all the electricity needs of the Earth, there were about 1122 million watts, which is the rotation of the planet would affect 7 milliseconds in the next century, the authors calculate. This is similar to the change of speed affected Natural phenomena, such as the moon pull and changing dynamics within the core of the planet.
