One of the bigger surprises at this year's Toy Fair was the general lack of green-themed products. We saw a few green toys here and there, but it seems that the toy industry is lagging behind others when it comes to marketing environmentally responsible products.

As an exception, Southern Californian tech-toy company OWI had a pretty nice spread of solar-powered robot kits. Targeted to children ages 8 and up, the kits are designed to be easily assembled while teaching them the principles of alternative energy sources. Priced between $11.95 and $17.95, the kits are available in a series of different forms, including Peppy Orangutan, Aerial Cable Car, Sonic F1 [racecar], Flapping Sea Gull, and Valiant Viking Ship [pictured above], among others.
