This book is a large compendium of recent bioengineering design projects or ideas: e.g. an eco-friendly brick, pigeons that poop soap instead of toxins, a bridge formed out of tree roots, algae as biofuel, oysters as water filters, concrete that "heals" itself, etc. It's very well-organised, and each project comes with a concise description and many photos. At the back of the book are interviews with some of the designers/scientists involved in certain projects.
I found this a thoroughly entertaining and interesting read. We get a good variation of selected projects - from those very practical and addressing urgent needs (e.g. sustainability, food, fuel), to others that are artistic (there's a whole section on it), futuristic (bio-buildings & cities for instance) or fantastical in nature (like the one where pigeons poop soap). And despite the complicated science behind it all, each project was explained simply enough for the layman to understand.
A well-recommended read for those interested in this field.
