When the Milan Expo opens next year, the centerpiece building will be a masterpiece of sustainable engineering. Designed around the idea of an urban forest, the new Palazzo Italia will generate its own electricity, and will be clad in materials specifically designed to clean the surrounding air. The designers, Nemesi & Partners, are using photocatalytic cement - basically, concrete that's been mixed with titanium oxide. When the building material comes into contact with ultraviolet light, the titanium oxide reacts with nitrogen dioxide in the air, converting the pollutant to a salt that can easily be washed away. The building will open in time for the Expo's launch next May, and we're already planning to book a trip over so that we can spend a day sniffing the air next to the building. -

SolarBotanic is a company which researches and specializes in an emerging tech dubbed biomimicry -- which seeks to mimic nature, and use nature-inspired methods to solve human problems. SolarBotanic is focusing on energy production, and, to that end, they've developed what they call Energy Harvesting Trees. The trees aren't "real," (they're just modeled on real ones); these are composed of Nanoleafs, which use nanotechnology designed to capture the "sun's energy in photovoltaic and thermovoltaic cells, then convert the radiation into electricity." They also have stems and twigs which house nano-piezovoltaic material which act as generators producing electricity from movement or kinetic energy caused by wind or rain. The company has several patents on the technology already, and are currently seeking partners for funding and development. We don't really have any details about what these fake trees look like -- but Thom Yorke's probably going to write a song about them.
