76196-The use of hydropower as a renewable energy resource could be significantly expanded if low-head systems could be exploited. Recent low-head (

An innovative integrated motor/propulsor (IMP) system is proposed that will improve the power density, efficiency and reduce acoustic signatures over existing designs. Gains in power density will be achieved by reducing the required motor torque in combination with motor structures that improve… More

We believe the following improvements are possible in vaneaxial fans: efficiency through improved fan blade design, coupled with the freedom to operate at speeds substantially higher than 3600rpm; reduced size by operating the fan at higher speed allows s

There are a large number of opportunities for extracting energy from flowing streams of water. Many of these streams are manmade. As an example, more than 15,000 publicly owned wastewater treatment facilities operate in the United States. These facilities process in excess of 34,000 million… More
