Yes, but that is pumping heat, not generating electricity.
Ground source heat pumps are for real, but home scale geothermal, not really I shouldn't have thought. You might theoretically be able to generate electricity in an area such as Rotorua, but it would be pretty dangerous.

It will be a scam Isnt there some theory, maybe from tesla? About magnetic waves in the earth? As a source of electric energy

No, Tesla wanted to develop wireless electricity transmission. However it was too inefficient. His theories were used for wireless radio transmission however.
The earth's magnetic field is too weak to generate electricity, and even if it was strong enough, it wouldn't work as the magnetic field needs to change polarity for electricity generation.
https://physics.aps.org/articles/v9/91 Electric Power from the Earth’s Magnetic Field "A cylinder 20 cm long and 2 cm across would generate tens of nanowatts at tens of microvolts."
You would have difficulty measuring such a small amount of power.

haha, and the Nigerians have money for you too.

Yup. You can get a bit more from things like radio waves. Harvest power from changes atmospheric pressure as weather changes, differences in temperature over a day. There are a tons of different sources of "Free" energy.
And of those, there are about 3 that get you any more than nanowatts. Enough to run a clock if you're lucky.

Nikolai Tesla and many others like him had ideas like this, BUT,BUT, these will never happen until the world runs out of oil, geo thermal power, and anything else that wont last forever, like wind and solar. There are numerous cases of good men with good ideas that have died in suspicious circumstances AND all their research work dissappears along with them.All to do with how much money the oil barons can extract from the peasant population.

Tesla had ideas about power generation using AC generators which are used now. He also had ideas about wireless electricity transmission, but we just use power lines as it is much easier and more efficient.
He didn't have any mysterious ideas about harvesting magical engergy.
