[Stoves] CO monitoring seeking practical analogues in localtesting methods for the 90% of the rest of us

[Richard Stanley]

Dear AD.,

Thats exactly the kind of approach that we all need : Thanks so much for your insights. The demarcation of CO concentration  might also have analogues in the plant and insect world too. My hope is that with any   range of such indicators, the local wood/ charcoal /biochar/agroresidue briquettes  and/or any of the various stove user out there would be able to source and sustain their own indicators --It only makes sense to not only create awareness amongst the ones at the most risk. It remains essential that those who are decrying hte problem provide the practical useable solution for use by that same population..

Aluta continua,.. 

Richard Stanley,

(the analogues can be developed through local institutional testing and calibration to their instrumentation later on...

Placing a few in a clear 500 cc  Solo Plastic cup and injecting in a known amount of CO. Report both time and concentration when they die might work. Gas pulled from a stream of CO from a tank using a gas syringe and injected through the wall of the cup.  We need to see if it kills them at concentrations we can use. But I don't see someone sitting and staring at the fruit flies all night! Still need a buzzer.
