Are they generating more power than they are spending by making the train go? Has Barcelona mastered perpetual motion??
It's good thing, sure, but it's no savior. The blurb makes it sound like it's a net gain of energy, and that's impossible. It's not free energy. It's just upcycled waste.
It reduces waste, yes.
Sure, and that's not a bad thing. But what is revolutionary and newsworthy about what Barcelona is doing?
The revolution is that they are doing something that has existed since the early 1900s... But it's in Barcelona so it's chic.
It's cool and all that, and likely just a side effects of the new trains having that.
