Kelly Hart is the creator and webmaster of www.greenhomebuilding.com and www.dreamgreenhomes.com, and has been involved with green building concepts for much of his life. Kelly spent many years as a professional remodeler, during which time he became acquainted with many of the pitfalls of conventional construction. He has also worked in various fields of communication media, including still photography, cinematography, animation (he has a patent for a process for making animated films), video production and now website development. One of his more recent video programs (now released as a DVD) is A Sampler of Alternative Homes: Approaching Sustainable Architecture, which explores a wide range of building concepts that are earth friendly. Kelly is knowledgeable about both simple design concepts and more complex technological aspects of home building that enhance sustainable living. He has even designed and built a solar-electric car that he drove around his neighborhood. Kelly, and his wife Rosana, lived for many years in an earthbag/papercrete home that he designed and built in the mountains of Colorado. In addition to "Remodel Green," Kelly has written "Rolling Shelter: Vehicles We Have Called Home," as part of his Green Home Building series.
