[Stoves] solar cooker response (changing thread name)

[Michael N Trevor]

If you are going to go the inductiopn route you may need to check your
cookware.. VERY SIMPLE check it with a magnet. If it is it will work. This
means yes your great grandmother's cast iron heirloom will work. Carbon
steel wear much lighter also work.
