I want to show this awesome video if anyone don't know this technology of Induction Heating. More details on Induction Heating, Wikipedia.
This is scientific achievement - this technology that doesn't require fossil fuel to produce the thermal energy necessary to melt Aluminum, Iron, Cobalt, Nickel, Germanium, Gadolinium, etc. Fossil fuel has advantages over Induction Heating by the terms of cost-efficient. But... Electric Bill > Pollution. I'm rather to have nasty electric bill than producing the waste of fossil fuels potentially damage Earth's environment.
