With the Futusly Portable Miniature Solar Heater you can stay warm anytime, anywhere while significantly saving on electricity costs. You no longer have to worry about your house and car being covered in snow on cold mornings! The Futusly Portable Miniature Solar Heater uses a metal ball trigger mechanism developed by NASA. When activated, the metal ball trigger mechanism triggers a molecular rotational movement. The movement of the molecules releases kinetic energy, which not only prevents the water molecules from freezing, but also performs the fundamental task of heating the environment. Because the Futusly Miniature Portable Solar Heater is portable, it can reach from your car to your house, comprehensively warming your 100 square foot home in 15 minutes. You can rest assured that your home will be at a comfortable temperature in the winter, saving you a lot on your annual electricity costs. It also helps you avoid expensive repair costs caused by roof damage, building collapses, internal leaks, and other problems caused by snow drifts on the roof.3 OUR GUARANTEE We are confident that we offer some of the best products on the market.
