The bladeless Dyson fans are mesmerizing. No apparent moving parts, yet a stream of air. Velux has a skylight-sized thermal solar panel that can be visually integrated with other skylights for a coherent design. I don’t have the name, but there is a phase-change product that is an interesting thermal mass that can be added under drywall to better balance heat/cooling loads throughout the 24 hr cycle.
And of course I love the Demilec product – spray foam insualtion has radically altered my practice and my clients use of their homes – the walls no longer have to be overbuilt, and the foam hides all sorts of builders and architects’ sins.
