The rest of the world is not standing still with regards to solar energy while the US gazes at its navel and cannot seem to get anything done. It's a damn shame that one political party - the GOP - seems intent on stopping any type of progress on anything, except for cutting taxes on the wealthy. We can't even get any desalination plants going, and we have some serious droughts across the country!
Australian desert farm grows 17,000 metric tons of vegetables with just seawater and sun.
This incredible farm makes tomato plants bloom in the desert using nothing more than sunlight and seawater. Needing no soil, fossil fuels, groundwater, or pesticides, Sundrop Farms grows crops in a hydroponic greenhouse lined with water-drenched cardboard. The 20-hectare farm officially opened on October 6th near Port Augusta, and their desert-grown tomatoes are already for sale in Australian grocery stores.
Sundrop Farms works agricultural magic. Conventional farming won’t work in the desert region, but that doesn’t matter for this desert farm. It obtains water from the Spencer Gulf, and desalinizes the water using renewable energy. 23,000 mirrors reflect light to a receiver tower to generate solar power. When the sun is shining, the system can provide 39 megawatts of clean energy – that’s enough to keep the desalination plant working and power the greenhouse, which is heated during the winter.
