There use to be machine shops everywhere in my country. In the late 1990's they all closed, I have no idea why? The lathe work is really good, just like all the work. Very skilled workers!👍🏻
NO, DON'T BE A FOOL. There is no "free energy" out there - not from flywheels, not from gravity, not from magnets, not from weird coils & transformers, not from ANYTHING. Sorry if that rains on your celebration, but it's just the simple truth.
