@elonmusk Not suggesting every building do this just enough to offset lost ecosystem and maybe a little more. Why not utilize all building surfaces, solar on top plants on sides for large buildings
@elonmusk Captures runoff, CO2, with the right plant mix and water system can be sustainable and maintain local biodiversity. Great for balancing out urban growth. Intriguing idea for large gigafactories. Doesn't do enough to offset future rocket sector growth tho.
