CCAT'sMEOW, short for the Campus Center for Appropriate Technology's Mobile Energy Operations on Wheels, is a highly mobile solar power station posessing the ability to send 60 amps over 24 volts from energy stored in eight batteries collected from solar panels mounted on its roof. Recent electrical work and roof mounting systems show how to turn this ordinary trailer into a beefy energy supply. Also see: Appropedia.org: Photovoltaic Category. | |||||||||||||||||

Did you ever notice that place in your back yard where you always want to just sit and kick back but didn't want to install a commercially produced park bench? Jessica Rendon led a supported campaign to finish the construction of the cob bench at the Campus Center for Appropriate Technology at Humboldt State University, California. This cob bench is fully loaded with an urbanite/cinder block foundation, seashell and mirror inlays, inset soil analysis, and more! We do just about everything cob around here. So sit down, kick off your shoes, and stay a while. Also see: Appropedia.org: Cobb Category. | |||||||||||||||||

Need to fix up that old cob bench you made in your back yard? Nat Davies made additions to the cob turtle and also fixed up an older cob bench in the community. A fine cob fixer is she as her hands on application and use of basic tools and techniques provide just the right touch to aid any failing cob project. I could go for a cob massage myself just about now. Also see: Appropedia.org: Cobb Category. | |||||||||||||||||
