ShadowGrid maps Manhattan's urban canyon shadows to create micro-cooling zones where popup igloo structures provide refuge during extreme heat waves.
Walking through a scorching Manhattan summer day, you turn a corner into a shadow and suddenly feel 15°F cooler as you step into a futuristic igloo dome emitting a fine mango-scented mist—your phone automatically connects to blazing fast WiFi, and the app pops up: "You just saved 4.2 kWh of grid energy. Enjoy your free mango smoothie at the next location."
