As an writer, I occasionally use the internet for research. Currently, I am working on a book where I wanted to do some checking on camp-stoves, specifically the type that use Sterno fuel.
Now I have a slew of e-mails suggesting the purchase of camp-stoves. My apologies to the merchants. It was not my intention to misdirect you, but I am not interested in camp-stoves. My days of camping are long behind me. Besides, from what I learned of Sterno Stoves, they are not well suited for camping. They have a hard time boiling water. In my book, my character decided on the old gasoline type. The flame burns hot and the fuel is readily available.
Don’t get me wrong, the Sterno Stoves do serve a good purpose, but not for survival. The flame is not hot enough to boil more than a quart or two of water. Propane or (or if available) is much better for most purposes. There is a one burner version that is not much larger than the LP bottle and it can generate a good uniform flame for quite a while. It would very likely be a good stove for power outages, unless like me, you have a gas stove.
The one real laugh I have about it all, those monitoring my internet queries often have a false impression of me and there is not one thing I can do about it. None of there e-mails permit return messages.
