After developing Food and Water security, next on the Hit Parade for people concerned about diminishing fossil fuel resources is developing Renewable Energy sources that are clean and affordable.  Often unrealized is the fact that while some energy technologies SEEM Renewable and Clean, they really are not.

Take Electric Vehicles, EVs as they are normally abbreviated on Renewable Energy Blogs and information sites.  No emissions coming out of the Tailpipe, they SEEM clean.  Going just a layer or two down though, it becomes apparent EVs as designed now are neither clean or renewable technology.

Beyond the fact that these technologies are dependent on fossil fuels for their creation is the fact their production also depends on long Global Supply Chains, with most of the Factories that produce such things now located over in Asia.  In a collapse of supply chains, the replacement parts for such complex technology are unlikely to be available for very long.

To resolve these difficult problems, at SUN we concern ourselves with developing more basic forms of Energy collection and Storage, utilizing materials available locally and construction methods not dependent on high technology factories that can be implemented easily by individuals and small communities.

Our D.I.R.T. initiative will focus on basic energy needs and demonstrate methods for Thermal and Mechanical energy collection and storage, independent of fossil fuel inputs.  We seek to develop and promulgate such methods here on the pages of SUN.

    I’m thinking of converting my semi-derelict natural gas water heater, into a rocket stove for the garage. Then build a similar rocket stove in the basement to heat water in tanks, and coils in the main floor, to heat the house.
