If you like access to free hot water virtually anywhere on the planet than this Solar Thermos for Boiling Water is a great thing to have.
A great addition to your camping gear or bug-out bag, this solar water heater uses a high efficiency solar tube to collect solar heat. The parabolic reflective outer shell helps by concentrating the solar heat to the inside of the cup.
All you have to do is put some water in it, set it out in the sun, wait about 30 minutes, and collect your hot water. It can heat 465 ml (16oz) at a time. While you won’t be taking a bath with it, it’s plenty for a hot cup of coffee or soup. All at zero running costs!
It’s also a great way to purify bacteria in questionable water. It can be used in any temperature (even freezing) so long as there is direct sunlight.
