Excerpt from Mining and Ore-Dressing Machinery: A Comprehensive Treatise Dealing With the Modern Practice of Winning Both Metalliferous and Non-Metalliferous Minerals
Wind. - For giving motion to machinery, windmills have been and still are very extensively used. Engineers of the last generation devoted much attention to the construction of windmills, and brought them to great perfection. The introduction of steam-power - manageable, and always to be depended ou - has, in a great measure, superseded that of wind. True, after the first cost of a windmill, the power is comparatively inexpensive; but it is so variable in intensity - sometimes, when it is not required, exerting great force, and sometimes, when it may be most wanted, totally ineffective - that it is generally preferable to apply a force, perhaps considerably more expensive in its production, but constant, steady, and completely under control. The intervention of electric storage batteries, however, is an obvious method of reducing this evil to a minimum.
