Algae Towers, Carbon Nanotubes Coming to a City Near You

A hydrogen-producing algae tower is one of the Blade Runner-worthy visionary ideas for urban development that emerged during the City of the Future Contest San Francisco, sponsored by the History Channel. (Interest in algae as a biodiesel seems to be growing--read more here and here.) Incorporated in HydroNet, the grand prize winning concept by San Francisco-base design firm IwamotoScott, the towers are based on real science, according to partners Lisa Iwamoto and Craig Scott. The firm's project, designed in one week, also includes hydrogen-fueled hover-cars, geothermal steam baths, robot-drilled tunnels, walls "structured using carbon nanotube technology," and tunnels for transport of water and power. ::Via ArchNews Now ::The History Channel ::SFGate.com ::CNNMoney.com More on ::Biodisel ::Carbon Nanotubes
