Foot Pump + Balloon + Adjustable Valve + Stove equals clean combustion.

Now we just need a balloon that's cheap enough and easily replaceable.

My garden sprayer can hold about ten minutes of compressed air for  
periodic spraying.  What should be the target, ten to one?


Over ten minutes cooking time, one minute of total foot-pumps done  
periodically ?

  Let's see, for ten minutes of cooking time, you'd need to top off  
the pressure vessel with six seconds of pumping once per minute?

Once you've got a pan of food sizzling, there's always that down-time  
when it just has to be covered and allowed to cook and further  
stirring would just waste heat.


  Letting the compressed air run down during that time would have the  
effect of dropping the heat to a simmer.


My sister is an EMT and gave me some stuff the Ambulance Co. didn't  
want anymore.

A couple of O2 regulators, tubing, and a foot-pump.   It looks like  
half of a rubber ball about six inches across.

I suppose, with the addition of a  one way valve and a pressure  
vessel, like an old garden sprayer... some inventive cuss could whomp  
up a foot-powered air tank.

After all, even just a trickle of air input to a MIDGE would get it  
burning red hot...


Hmmm.   I may just try this for my charcoal grill.
