A solar cooker uses energy from where to heat food?

This is something that should be promoted worldwide. Think of the difference it would make to the climate. It’s definitely something that I will look into.

They don't really work in the UK and other more northern climes, I think the sun has to be a certain height in the sky for the cooker to get hot enough do its job. But I enjoyed such a meal when I visited S Sudan - awesome invention!

Rosemary is a very good person

This would be great for any preppers out there! very efficient.
