Thanks Comrades Malcolm and Dave.
I have already considered upgrading from pedal power for the PC along with the wireless and TV to a coal fired TE up and down driven generator. Like so many of the things that I consider nothing eventuates which is probably for the better.
Overall there is little doubt that you are both right - the PC clearly needs a bigger and higher pressure boiler.
I am considering an electric bike to power the pedal generator whilst continuing my work on perpetual motion and it seems that a Babbage might be the answer in the meantime.
The existence of Babbage and his machines is one thing that I have learnt form this escapade.
