[Stoves] Pedal powered fan

[Boll, Martin Dr.]

Dear Kevin,

 

First of all I think it is possible. But to make a 5$ fan plus
energy-generator plus stove, we must de-lard as well the
bicycle-pedal-system as well as the fan and the stove too. The fan must be
locally made and low-tech; mechanically driven by a belt/string.
-Transmission by a big and a small circle-disk with V- or U-profile on the
periphery, to guide and hold the transmission-cord on both the disks.-

The big disk can be made of wood, metal, armoured brick or concrete ( Think
of making the profile notch smooth, for not wearing out the belt before
time), with quadratic axle-profile, where you easily can fix a lever and
pedal on each side.

-The big disk/wheel could be made as well as an old-fashioned water-wheel by
a pair of crossing wood-bars round the quadratic axle; my original thought
for a solution.

 I think it is possible to do that -if no other possibility- with wood too.
Naturally the dimensions must be wood-adequate, and not as the metal
original.

-The idea for a brick-wheel came when I saw your 5$ price to manage with.
That would be another task for Crispins Brick-maker.

When a transmission from pedal-disk 1 revolution to 10 revolutions of the
fan will be sufficient, I think it is possible.

For an according radial-fan I have a simple construction solution in mind
and I shall try to give a sketch later on.

 

Regards

 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
