Born of an initiative at the Center for Science and the Imagination at Arizona State University, this remarkable collection unites a diverse group of celebrated authors, prominent scientists, and creative visionaries--among them Cory Doctorow, Gregory Benford, Charlie Jane Anders, David Brin, and Neal Stephenson--who contributed works of "techno-optimism" that challenge us to imagine fully, think broadly, and do Big Stuff. Inside this volume you will find marvels of imagination and possibility, including a steel tower so tall that the stratosphere is just an elevator ride away, a drone-powered Internet, crowdfunded robots descending on the moon, cities that work like a single cell of algae powered entirely by the sun, and much more.
