Bamboo Sunshine Dollhouse is constructed of sustainable bamboo and includes a working solar panel in the roof.  An adjustable, fully operational solar panel absorbs light energy and transfers it to four rechargeable batteries through wiring in the walls, just like in a real house. This energy then lights five LEDs to brighten three rooms of the house with just a push of a button. A light, water-based stain is used on the bamboo and then polished with beeswax. This dollhouse comes fully furnished with nine rooms of bamboo furniture and a modern family of five. "The three-level home is the first dollhouse to offer eco-friendly materials with contemporary designs and modern technology, satisfying both a parent's interest in green products and a child's fascination with role play," Robin Lehnert, marketing manager at Hape, told TDmonthly. Launch date: 2009.
