The Solar Kettle boils water using just the suns power. This SunKettle uses a tube to hold the water and reflective panels to focus the solar heat. In as little as 30 minutes you can have boiling hot water, even in snowy conditions (assuming you have some sunshine).
Perfect for off-grid or camping scenarios. Not only great for making coffee and rehydrating survival/camp food but also good for sterilizing your water supply. Get your SunKettle Solar Kettle here.
