Abstract: A modular and portable motorized solar concentrator assembly for production of ethanol, electricity, potable water, or combinations thereof can include a housing and a reflective array. An airtight chamber is formed in the reflective array, and ancillary reflective concentrators can provide addition solar radiation thereto. An inert gas in the airtight chamber can form a low-humidity and air-free environment. The portable motorized solar concentrator assembly can engage an electricity producing plant, a desalination plant, an ethanol producing plant, or combinations thereof.
