To paraphrase Boston Mayor Martin Walsh, “Your cellphone doesn’t just make phone calls, why should our clothes just be, you know, clothes?” But Designer Pauline van Dongen puts it so much more pretentiously. "Wearable Solar is about integrating solar cells into fashion, so by augmenting a garment with solar cells the body can be an extra source of energy," she explained last December at the Wearable Futures event in London. "It's really about the true integration of technology and fashion, which can transcend the realm of gadgets." Shown: a leather and wool prototype, uh, dress, that incorporates flexible solar cells, storing enough energy to half-charge a typical smartphone. Of course, it makes you look like an extra in one of the “Twilight” movies is a small price to pay for a Sustainable Alternative.
