A Man and His Turbine Engine

Submitted by on October 5, 2016 – 3:55 pmNo Comment

by Suzi Thaye (Boothbay Register/Wiscasset Newspaper) David Stapp’s invention is “fuel-agnostic”  —  … It’s a nice spot for CEO Stapp to concentrate on his pet project, the Peregrine Turbine, a jet engine that can run solely on biofuels, but will work also work quite well on conventional fuels like diesel fuel and natural gas, since they are also air-combustible.

Peregrine Turbine Technologies, owned by Stapp and investors, was started in 2012 for the purpose of developing a very high-efficiency jet engine.

Though jet engines are mainly used for aircraft propulsion, Stapp said they’re used in a lot of other applications as well, including electric power generation and tank propulsion, like the army’s M1 Abrams Tank.

In 2011, Stapp established a partnership with Bob Brooks, now the Chief Business Development Officer and COO of PTT, and the two decided the idea for the turbine engine was breakthrough technology. The Peregrine Turbine was born. The PTT website states: “Our technology is projected to bring a whole new level of performance, fuel efficiency, and low emissions to the turbine world.”

The biofuel-propelled Peregrine Turbine is the first engine of its kind. “No one has ever made one like this,” Stapp said. “It’s a brand new concept, and it’s between 25 and 60 percent more fuel efficient than any jet engine out there.”

The company is working with Sandia National Laboratories in Albuquerque, New Mexico.

Stapp describes the engine as “fuel-agnostic”: It doesn’t care what it’s burning, as long as it can burn in air. That’s not true of any other turbine engine. Kerosene-based fuels and natural gas can be burned in a jet engine, but the Peregrine engine will burn only biomass. “We can burn chicken waste or ground up rubber tires — anything that can burn in air can be used in it. We call them air combustible fuels.

“Our engine doubles the efficiency of being able to convert biomass to electric power, so we can dramatically change the economics of using biomass to generate electric power.”

The project is being funded in part by the U.S. Air Force Research Lab in Ohio and the Office of Naval Research in Washington, D.C. Stapp is raising funds for the company through the sale of equity in the company.  READ MORE
