What if you could desmog your neighborhood just by installing new roof tiles? Well, that’s exactly what BoralPure Smog-Eating Tiles do. The tiles are coated in TiO2 (titanium dioxide) which reacts with and neutralizes NOX (nitrogen oxide) particles in smog resulting in a harmless precipitate that accumulates on the roof and washes away in the rain. Simple but brilliant and the tiles cost only about $650 more than a standard 2500-sq.-ft. tile roof.
We all love solar power but there’s no denying that it’s still quite expensive. The main price driver for PV panels is silicon – reduce that and the cost goes down. So that’s exactly what Solaria did. Their monocrystalline panels use 50 to 70 percent less silicon because rather than cladding the entire module with PV panels, Solaria makes use of a patterned-glass lens to refocus light onto a thin strip of solar cells. The panels are durable and – you’ll like this part – they cost about one-third less than comparable panels.
