I could have sworn that for cyclists it went by MPB(burrito), at which case I am nearing 73 miles currently. With a rig like that, a wide enough variation on gear ratios, and no headwind I don't doubt that I can beat 100mpb.

How many grams of carbohydrates and fat on the burrito? Is it an Imperial or US burrito? Did you weigh yourself before and after? Inquiring minds want to know

It kind of sounds like the HHO scams that just claim you can use water for fuel and then lose you in details that defy logic.



Miles per turkey sandwich? Honestly, I think that is a better measurement, although you could have a small one with cheap ingredients while I made a party sub, but why get technical like MPPoTS, Miles per pound of turkey sandwich?

Cyclists do not use the water for energy, but instead for their cooling system.

True so that means you could compare humans to steam engines for the water used? Any thoughts?

Interesting, but I imagine that coal contains more carbon than human food.

I will ask my favorite sport nutritionist, Joe Pastabelli Actually there are any number of books and sources on food as fuel for humans. See "High Tech Cycling 2nd Ed." edited by Edmund R. Burke. Chapter 9 on nutrition was written by Asker E. Jeukendrup with a bibliography of 27 entries. Of course all bio-fuel is produced by plants removing carbon dioxide from the atmosphere.

Came across this discussion and the numerous comments. I don't expect to ride a velomobile at highway speeds at my age but many of the trips within a 25 mile radius are suitable for bike riding. The big gains in aerodynamics are what I am after with the additional benefit of protection from the elements.

I'm surprised that you are not trying to work with a recumbent bike. Although they are a lot more expensive to find around.

There are pros and cons in the selection of a recumbent or an upright. I would not discourage anyone from trying a recumbent. I have ridden the Linear LWB made by The Bicycleman, Pete Stoll. A LWB recumbent does not fit down my cellar stairs, may weigh more, may not fit on the bus rack, and I like the height of an upright in traffic. My target market is low income commuters on mountain/hybrid bikes and a goal of reducing drag by 25%. Many of the lessons learned apply to scooters and light motorcycles.

A 4 person pedal car with electric assist based on a low drag body such as the Mercedes-Benz C-111 Mk. 3 would interest me some day as a project.
