@Kaputnik - Efficiency of human v moped
It was Dr Yan from "Bang Goes the Theory":
http://www.bbc.co.uk/programmes/p00q0g8y
Using 1,000 calories of petrol, the moped managed 140 mpg. Using 1,000 calories of fry up (the breakfast of champions), Dr Yan managed an equivalent of 575 mpg!
To make it fair, Dr Yan was on a fully loaded tourer with two wheeled trailer to equal the moped's weight, so I think that an average commuter will be much lighter and have half the wheels...
Average speeds were higher on the moped (30 mph), although the bicycle average wasn't quoted...
The massive difference was put down to rolling resistance, wind resistance and gear box losses, as the underlying efficiencies of engine and human were described as similar.
