Fabricating Mechanical Metamaterials

The horizontal-axis wind turbine has become an efficient and economical means to produce electricity. Some of the largest machines can produce as much as 15 MW when running at full capacity. But such turbines can be too complicated for small-scale operations or for capturing wind power in urban settings.&nbsp;
