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."

I have been leading an open renewable energy project and I think we have 2 novel ideas for scalable and reliable renewable electrical power, the Solar Ammonia Absorption Convection Tower and the Compressed Air Wind Electrical Generation System.

What are your ideas for renewable power generation and conservation for the data center and other areas of industry?
New Ideas Only. Please don't mention Solar PV"

The idea is to "roll-your-own" geothermal source by capturing heat from the ambient air with a solar powered absorption heat pump, store it underground and generate electricity from the air cooling convection. When the air is cooler the stored heat is then used in a reverse process to generate electricity by transferring the heat back to the air when it is cooler (at night or seasonal). There are many additional benefits including clean water capture from the "dehumidifier" effect of the air cooling, construction from common materials and thermal storage that may be incorporated into dwelling heat systems."
