Want something that is easy for you to take around to heat stuff up? Well, that’s the Stoov! Designed by Mathieu Baele, this concept device sports an internal battery, robust shape for travel, touch-screen activation and even electromagnets, meaning you’ll be able to attach the a couple of Stoovs to the side of your pot to heat stuff up. If such a this were to become a reality, it would seem that you could have some fun playing practical jokes on people with this, such as heating up the sides of their car or something.
