Why not try CETO
http://www.ceto.com.au/home.php - they are trialing it at the moment. Typically the Oz Govt and state Govts dont want to know about it. It produces electricity and fresh water in variable percentages of each, so during the day use it to produce sufficient electricity to meet the demand (supplementing solar,wind etc generation) and produce mostly water, at night produce electricity until the load drops and then go back to water production. By the sound of it, the only thing you see on land is a pump house, a generator house , water pipes (unless underground) and transmission lines (which also could be underground). You get water and power without greenhouse gases.
