[Stoves] Gas heater without flames comment

[Ronald Hongsermeier]

Dear Group,
Do you think this is significant enough that several of us should go 
into chicken-farming?

I come from a town that was the center of publishing about Turkey 
Farming for quite a while-- is turkey manure similarly ammonia laden?

regards,

Ronald von Nichthuhnenbürgen
