Cleaner Air Without Trees

Let's face it, trees suck. They're so old school. A Los Angeles of the future needs less wood and more metal. Shiny, shiny metal. Via the cool hunter, we're glad to see someone is thinking like us. Somehow, these metal cylinder thingys clean air while also sort of providing shade, and they're self sustaining thanks to solar panels. No info on price, availability or dimensions, but we can confirm they are shiny and metal.
