"Eugenia Kalnay, a prominent atmospheric scientist at the University of Maryland, has been thinking about this idea for a decade. Kalnay is small in stature, soft-spoken. But she's made her name with big and bold ideas. And what could be bigger and bolder than reversing the course of the world's biggest desert?" "It is wonderful!" she says, and her eyes go wide with an infectious joy. "We were so happy because it seems like a major solution for some of the problems that we have." The super solar farm she imagines is huge, as big as the entire United States. And it would generate four times as much electricity as the entire planet consumes right now. Kalmay talks of novel high-capacity transmission lines delivering power to Europe and the rest of Africa. I told her that the whole scenario sounds like science fiction. Kalnay disagreed. "It would be science fiction if the technology was not available," she said." If the Sahara Desert were transformed into fertile farmland, it could solve the world's hunger problems. https://www.npr.org/sections/goatsan...possible-dream Solar Farm Cost Per Acre ? InnovativeSolarFarms.com A good number for solar farm cost per acre is typically $500,000 here in the U.S. US = 2,429,914,880 acres This equals approximately 1.2 quadrillion dollars. I know that sounds like a lot, except if we simply taxed the one percenters a bit more and made them pay their fair share.
