Italian designer Ermenegildo Zegna has shown a high-end solar jacket at a fashion show.

The forthcoming Solar JKT from Zegna Sport is "the first premium segment" [read: morbidly expensive] outerwear product in the world that can recharge a cell phone, iPod or other device using solar power, the company claimed.

It's certainly not the first solar jacket. Just the first from a brand-name designer.
