As far as wearable technologies go, the Dandelion portable windmill is more than a load of hot air. Designed by Mary Huang and Jennifer Kay—and constructed using 99 percent reclaimed materials—this quirky structure is as practical as it is elegant: It creates its own energy while you’re walking or standing outside on a gusty day.

BLOW WIND GLOW

Tiny circuits convert the energy generated from the moving blades into light, which in this prototype’s case, takes the form of tiny white LEDs.

If glowing like Tinkerbell isn’t quite your bag, you can also harness the energy to power a small electronic device, say a cell phone that needs a little power boost or an iPod that needs some extra juice. Paging Imogen Heap, we think we have your next Grammy Awards dress right here.
