Electrochromics Tinting Windows by Sage

While we're waiting for flying cars, we'll settle for electronically tinted glass, now available in triple-pane construction with a whopping R-value of 8 (versus, say, 3 for double-pane windows). At the touch of a button, the built-in nanotechnology dims the glass to shade a room. Sync it with your home automation system to save energy.

A 30-by-60-inch awning window from H Window Company costs about $1,575; sage-ec.com
