SHPEGS: DIY Solar/Geothermal Electricity

rohar writes: "SHPEGS is an open design not-for-profit project to design and prototype a base load renewable electrical generation system suitable for moderate climates and built from common materials. The design centers around creating a local geothermal source with an efficient solar thermal water heater system and can be scaled from the single residence to the mega-project. The project was recently featured in an in-depth The Future of Things article. The heliostat system used in Europe's First Solar Thermal Plant could be used in a scaled down SHPEGS system with Practical Solar's small scale heliostats."
