Shall we do the math on this? Pogi's Zone 2 power is apparently around 320W. That puts his FTP around 500. Assume he's doing a climb at tempo, say 6W/kg based on system weight. The power density to beat for your mechanical doping device is 166g/W. But keep in mind, that's the power it has to do in order to just break even and not slow him down.
Also the gains from your device are probably erased if Pogi forgets to poop before starting the stage.
And have you seen the man's bicycle? It is not as if you can just drop a couple of D cells down the seat tube.
