A farm in Australia is now using seawater and sun to grow vegetables, and it does not require pesticides or fossil fuels. Instead, it relies on a sun-powered desalination plant and a greenhouse to irrigate tomatoes. This is of course a great step forward along the lines of Plan A, however it is impossible, or at best impractical, to attempt to recreate the system far from the ocean. The cost of pumping water hundreds or thousands of miles inland would be prohibitive; in addition, it does not generate a surplus of electricity as Plan A would.
