San Fran Of The Future, Fast-Forward 100 Years
"IwamotoScott envisions the city as Hydro-Net, using “Geothermal Mushroom” structures to extract heat and water from deep in the earth, and whimsical “Fog Flowers” to render moisture from the air and grow algae, which would then be turned into hydrogen for fuel. Zipping through underground tunnels are hydrogen-fueled hover cars, coursing through the multi-use veins of this future city that’s learned how to live without fossil fuels. Hope it’s earthquake-proof. "
Geothermal mushrooms... sounds vaguely familiar to our college days.
