Patents by Inventor Peter John Kittel

Peter John Kittel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cross flow turbine with straight vertical and helical slanted blades
    Patent number: 10024168
    Abstract: A structural duct apparatus includes a cross flow turbine for use in a fluid flow. The turbine has at least one straight vertical aerofoil blade and at least one helical aerofoil blade slanted toward the direction of rotation. Inner and outer walls of the duct apparatus provide an inner diffuser flow passageway that houses turbine power take off modules with the outer surfaces of the duct influencing flow direction so that where there are at least two ducts an open flow barrage is advantageously formed.
    Type: Grant

  • Extracting energy from flowing fluids
    Patent number: 9062427
    Abstract: A Barrage apparatus is a method and device for extracting energy from flowing fluids in an open flow by means of a submerged barrage or barrages that obstruct and channel flows at increased velocities to downstream turbine power take off modules. Increasing the velocity of the flow increases the amount of power available for extraction thereby providing opportunities to extract energy from low flow sites and facilitate the use of low cost small marine turbines to provide an ecologically sound, efficient and cost effective method of renewable energy extraction from fluid flows.
