Don't tempt me. :lol:

Come on you chemistry experts out there, are there oils in a banana that could be extracted for lubrication purposes?

Don't know about lubrication, but I do recall a friend who put a pile of banana skins into a whining car diff in SA once. It was very successful at both quietening the diff down and getting the car sold...

When you give a cyclist a slice of bread that is 120 kCals, one would think that if the kCals per mile of the cyclist is 40 kCals per mile, the slice of bread would last 3 miles.
We all know this is ridiculous.
If it were true, a 300 km Audax rider would require 65 slices ( 5 loaves ) of bread to complete the event.

What happens in reality is that dependent upon the cyclists physique and the intensity of the riding, most of the required 40 kCals per mile are taken from fatty acids through lipolysis during the steady effort.

You will have to do your own experimentation, but I require about 4 kCals per mile on a <100 km ride, 12 kCals per mile on a 100><160 km ride and 20 kCals per mile on a >160 km ride.

On some flat 100 km rides, I don't bother eating anything extra above my daily BMR. An ice cream, maybe.

Leading to infinite mpg.

I got infinite mpg out of my car today - to the supermarket and back, without putting any petrol in.

A friend went on a touring long weekend, contrary to weather forecasts it snowed a lot and they all ended up "stranded" in a remote pub. Based on his account of the whole trip, he averaged 42mpg :D

You will one day. Cars don't run on the padding in the seat. Think about it. :wink:

Also, if you overfill a car, the excess spills out onto the pavement. Similar to a man and beer,,, :lol:

I remember a comedian joking about petrol-saving devices and how he installed all the ones on offer, and his petrol tank overflowed every twenty miles! :D
