Zach Weinersmith is one of the leading pop-science cartoonists online with his blog "Saturday Morning Breakfast Cereal." Now, he and his wife Kelly have written a book about ten promising future technologies that could soon make our world a better place, if all goes well. Why build houses when you could print them? Why not just get our raw materials from the nearest asteroid? And wouldn't a lift into space be practical? It sounds crazy, but we live in a time when all of this could become reality—soon! It's brilliant, fascinating, and highly entertaining reading for anyone who wants to know what amazing things the future holds.
