Somebody estimated that if cables will be extended from pole to pole and contacts placed on equator we could obtain 100.000 V, as Earth rotates in its own magnetic field.

Heard of any such effects on N-S railroad tracks, like Miami to Quebec?
Or power lines?
Ocean water is a conductor and very nearly spans the poles.
Crackpottery is easy to test.
Sorry. Mind elsewhere.Crazymechanic said:@sophiecentaur so how it is actually , could you please see my last post, as I believe this thread just got forgotten a little bit, but not 100% finished.

To harness energy from Earth's magnetic field, we can use a device called a magnetohydrodynamic generator. This device converts the kinetic energy of ionized gases in the Earth's atmosphere, which are affected by the magnetic field, into electrical energy.
The potential of harnessing energy from Earth's magnetic field is vast. The Earth's magnetic field is estimated to contain about 10^25 joules of energy, which is equivalent to the total energy consumption of the world for 200,000 years.
Harnessing energy from Earth's magnetic field is a clean and renewable energy source, so it has minimal impact on the environment. Unlike fossil fuels, it does not produce greenhouse gases or other pollutants, making it a more sustainable option.
While the Earth's magnetic field has a vast amount of energy, the technology to harness it is still in its early stages. Currently, it is not feasible to use the Earth's magnetic field to power homes and cities on its own. However, it can be used as a supplemental energy source alongside other renewable energy sources.
One of the main challenges of harnessing energy from Earth's magnetic field is the low efficiency of current magnetohydrodynamic generators. Additionally, the technology is still in the development phase, so there are still many obstacles to overcome to make it a viable energy source on a larger scale.
