Hydropower, as you may guess from the name, refers to the use of water to produce power. It is one of the oldest and most often used renewable energy sources, becoming popular when the paddle wheel was invented in the 1800s and accounts for almost 3/4 of the US renewable energy use today. Before of electric power was widely available, hydropower was used to power mills, textile machines and for irrigation.

The solar collection concept is not new, but the concentrator is different from anything seen before on any renewable energy product.
