A solar kettle. Keeps 3 cups of soup or tea warm for your country walks or hunting/hiking/fishing trips or will help you survive the great outdoors. On a sunny day the solar kettle will boil water but even on overcast days the kettle will warm up water nicely. Note it will take up to 2 hrs to fully boil so you need to be settled in somewhere. If you're not going out so long or if it is a dark day then take a thermos. Find it at Nigel's Eco Store.
