Solar powered hat and glove: cute but probably not efficient

German designer Yiran Qian came up with the idea of embedded stylish solar panels into hats and gloves. Called Endless Warm, the concept would use solar power to heat hats and glove for your comfort. Given the small size of the solar panels, we doubt that this would provide much heat – it would probably be more efficient to wear a black hat. However, the idea that heat could be distributed in specific locations (fingertips?) is interesting. Solar technology seems a bit limited for this application right now.
