Dynamos & Power Plants -- Question Please Read! I know that cars need batteries to generate electricity to the dynamo to make the dynamo produce electricity continuously without stopping unless you switched off the car. The same to motorcycles. But I don't know whether the power plants do the same thing, so I need an answer for this question if you don't mind: Q: Do dynamos in power plants need batteries even if they're switched ON and producing electricity? If so, can't we remove the batteries from the dynamos after switching the dynamo on? Or do the "oil" and "nuclear reactants" do the work instead of batteries? Because I know that Dirt Bikes that have a "kick starter" can work without batteries via kicking the kick starter thingy to produce mechanical energy to the dynamo to make the dynamo produce electricity. But I heard that Cars cannot work the same as Dirt Bikes due to their "large engine and bla bla...", you cannot remove batteries from the car even if the dynamo is producing electricity so there will be no dangerous electricity going through the car. So I really wanna know, do power plants' dynamos have batteries or they work without them? Thank you!
