So my hope is to make something that can attach or stick to the inside of my snow goggle lenses so when I am on the top of the mountain, I can flip a switch (maybe powered by those usb phone battery packs?) and will heat up enough to defrost my goggles so I can see again. I wouldn't need anything fancy just a something to turn on when I need and can then turn it off once I don't. Any help or suggestions would be very appreciated thank you!
