Landscape artist Marc Granen developed Phytokinetic, which captures the air conditioning condensation and uses the water to irrigate the roof.

Landscape artist Marc Granen developed Phytokinetic, a roof garden for buses that helps purify the air in cities that don't have a lot of green space. Originally discovered by Urban Gardens, the system captures condensation from the vehicle's air conditioning system in order to water the roof. In cooler weather, the garden can also be manually watered.

Inhabitat reports that Phytokinetic uses a lightweight, 7cm-thick hydroponic foam which is much lighter than soil and can be easily installed on any shape of bus. The roof garden remains in place thanks to micro-perforated stainless steel bands fixed with an ultra-light protective mesh.
