Seawater greenhouses to bring life to the desert

The planned project would use solar power to evaporate salt water, generating cool air and pure water thereby allowing food to be grown.

''Paton said that the greenhouse produces more than five times the fresh water needed to water the plants inside so, in addition to producing water to clean the CSP mirrors, some of it can be released into the local environment. This can create a local microclimate just outside the greenhouses for hardier plants such as jatropha, an energy crop that can be turned into biofuel. The ability to create similar microclimates has already been proven in the demonstration greenhouses Paton has built''
