Wind Power: 20 Projects to Make with Paper

In this informative craft book, a celebration of wind and of innovative efforts to harness its energy, Dobson describes the geometric and aerodynamic principles behind windmills, sails, and wind turbines, then implements these concepts via 20 paper projects, ranging from a two-blade pinwheel to a dramatic "Squirrel Cage" turbine. Some may be put off by the text-heavy layout, but readers should gain a more palpable understanding of the subject matter by building and watching the graceful compositions function. Ages 10–up.
