I vaguely recall back in one of my engineering classes we did the math on turning all of the stationary bikes at the gym into power generating units. I believe the result was that the value of power generated was so utterly dwarfed by the costs in copper, inverters, etc. - not to mention additional maintenance costs - that it was at least an order of magnitude outside of making sense. Some of those economics certainly have changed over the last 15 years but many (I’m looking at you, copper) are rather fixed and won’t go down over time. Also > 1.4 TRex bites worth of force I have never seen T Rex bites as a unit of measurement before and I love it.
