What is this, you may ask. Excellent question. These futuristic leaf-like designs you see above are actually solar leaves that harness power from both the sun and the wind. This unique hybrid energy delivery system (called GROW) is the brainchild of sustainable design company SMIT (Sustainably Minded Interactive Technology). We love how it's inspired from nature, and can just imagine how beautiful it would look fluttering on the side of a building...
GROW actually exists in two versions: GROW .1 and GROW .2. GROW .1 (shown above) was exhibited at the Museum of Modern Art: Design and Elastic Mind in New York in 2008, and uses thin film photovoltaics with piezoelectric generators. GROW .2 is constructed around a stainless steel mesh system that allows ivy and other plants to grow with and around it.
GROW is made of 100% recyclable polyethylene and also has an internal monitoring system called WATTg that enables users to visualize how much energy they're generating and consuming.
Unfortunately, neither of the two GROWS are yet available for purchase, but SMIT hopes they'll be available in the next year or two at MoMA and Design Within Reach, so keep your eyes open! (We will, too.)
