The Paris metro article quotes 136 MW per year as available if all turnstiles are generating. Is this 136 megawatts all year, i.e. all of the time? Hardly, so we presume MWh, averaging out at about 15.5 kW continuously. I’ve added it to my collection of poor journalism (which, if all in paper form and burnt at the same time, could easily generate 15 kW, though maybe not for an hour).
Is this scientifically illiterate Paris metro turnstyle turbine thing still doing the rounds?
I mean, a healthy person can walk at 3mph. The earth’s escape velocity is 25,000mph. So all we need to get a rocket to the moon is about 8000 people going for a walk right?
It was a marketing initiative, and even Iberdola who came up with the concept stated it had no useful purpose in generating electricity. The amount of noise its created though has been substantial, so marketing win, I guess?
