EXCERPT: If you thought "concentrating solar power" (CSP) was dead, guess again. A new round of $11 million in Energy Department funding for cutting edge solar R&D includes six CSP projects, and one of them in particular stands out as a game-changer. It deploys the “whispering gallery” effect and 3-D printing to miniaturize CSP plants — those gigantic, lumbering installations that typically occupy hundreds of acres in remote deserts — into a comparatively compact, lightweight configuration suitable for urban and suburban site rooftops.
