But of course, this is exactly what we’ve been missing. I was definitely talking about this exact problem with the guys at the bar last night. “Why can’t we charge our phones with fire, guys?” Why, indeed, Simon. Turns out you actually can. And as with all things in the world, there’s a video of it on the internet machine.

This is what it is:

FlameStower harnesses fire to charge your battery. The device is comprised of a USB port, small stand, container for water and flat end to put over the fire; it uses a thermoelectric process to charge small mobile devices. The temperature difference creates energy because the higher voltage of the flame helps send electricity to the lower voltage of the water (the colder component).

This is how it charges your phone:

The electricity then flows to your device through the USB and adds some extra power. The gadget works with any small mobile device that can connect with a USB wire. You can easily fold the device’s legs in and collapse the container that holds the water for easy transportation; users can put the flat end over a flame such as a stove or a campfire.

Now pat yourself on the back for nailing down dad’s Christmas present so early.
