This is a great idea, I don’t know why they haven’t done this sooner. That said, 90% efficiency seems a bit optimistic for a system like this. Also, the trains use a lot more energy thAn a prius. This...

I’ve just read two articles on “tapping power” from highways or trains as if that could magically be used to power something else (like a city). During acceleration and cruise the train (or car) will...

The best thing would be to try it out on a shuttle train in NYC and do some real world research after they work out the technical details as to how to install the system and send the energy back into...

The London Underground has had a “regenerative braking” system ever since it was built by the Victorians 100+ years ago. Rather than use electrical storage, it uses gravity: the tracks slope downwards...

Why not just give the trains regenerative braking and a small battery to put this power into? (or even have them put it back into the grid via the 3rd rail, but this could be more complex…) You’d need...

@RichardNeill Re gravity braking – this is true (though I’m not sure it’s implemented on all lines) and I have a feeling they also have that on the Paris Metro and other systems. But in addition,...
