It seems like an excellent and innovative approach!! For a project like this to be adopted it isn't enough to show it is technologically feasible. It also has to make sense economically. There would have to be a significant installed and maintenance cost for a system that produces 1 million liters of water a day. Is the profit from 18,000 tomatoes enough to justify the cost. I realize that there are other concerns that should matter more than economics but realistically money matters. Hopefully they can show that the economics are as desirable as the environmental benefits
