7 авг 1870 г. - Lester Allan Pelton (1870s)

Описание:

Pelton was an American inventor who created/experimented with designing a better waterwheel. Instead of the jet of water hitting the cups in the center, he designed a wheel with split buckets side by side so that they could harness the kinetic energy of a small volume of water flowing at high speed. The simple idea easily doubled the efficiency of the standard waterwheel.
