[Stoves] Pedal powered fan

[Kevin Chisholm]

Dear Martin

Bicycle generated power is certainly practical, and it will work. 
Additionally, it is probably the most available, understandable, and 
maintainable way to generate adequate quantities of power to run a stove.

We hear frequent reference to "The $5 Stove." Do you think it would be 
possible to build a stove with a fan, and to provide a bicycle type 
generator system for operating the fan, for $5 or less?

Best wishes,

Kevin
