Pioneer Valley Renewables makes run of river turbines that are double the efficiency of what is on the market. This makes it the most efficient and easily installed source of energy whenever there is running water nearby. There is no need to make a dam, and this technology meets or exceeds the efficiency of small dams. Depending on size and speed, even our small turbines are 50-60% efficient and operate continuously. By contrast, wind turbines are around 30% and solar photovoltaic around 10-15% and operate only part of the day. Our technology was validated by utility testing in the Connecticut River and simulations by the US Navy, division of Advanced Surface Warfare, and the Navy gave us a grant to design a portable version. And two patents are already granted. We did a time motion study that showed two regular people can assemble and install it in less than 10 minutes.
