The present invention provides an integrated system for the combined purpose of electricity generation and water treatment and biofuel production. The configuration combines complementary sub-systems whereby outputs from one system are used as inputs to another creating a positive feedback mechanism that significantly increases system efficiency and output. Compensatory mechanisms between system components create a natural hedge in energy and water production against temporal variation in solar insolence levels. Secondary benefits of the invention may include carbon abatement, ground water improvements, and land regeneration.
