This book provides a lot of fundamental information about how people produce energy around the world.
Besides some traditional ways like fossil fuels, hydroelectric power, geothermal power and natural gas, I have never heard about nano power or living materials. In the bright future, I am seriously curious if people can charge their phone in their pockets or heat their clothes in cold weather by using nano cells. It is quite interesting, but really far from now.
Regarding living materials, the idea that people can ‘tell’ the materials to grow into a part of a car, or something else is certainly crazy today, isn’t it? Scientists still believe that oneday, we will never throw out anything, thanks to living materials. If we do not need a chair, it can change shape and become a bed instead. It is totally beyond my wildest dream but I cannot reject anything. Technology nowadays develops dramatically day by day makes it is very hard to predict the future! We will have to wait and see!
