And I in Java and .Net world, where it is more like "nuclear reactor included..."

...Only that, in Java, it's not exactly the nuclear reactor you want, which forces you to use someone else's solar power plant, and then they deprecate the original nuclear reactor (because it's known to leak uranium) in favor of a second nuclear reactor, which still doesn't work that well because it's the wrong polarity, so now you have three energy sources available in your project and if you plug your lamp into the wrong outlet everything explodes (see the Date/Calendar mess).
