This could be an engine of the future. It certainly sounds intriguing.

From The Milwaukee Journal/Sentinel online.

Poetry in locomotion
Inventor’s innovations give a high-tech twist to the steam engine

Inventor Harry Schoell has a new engine that he says can run on almost anything that burns. What’s more, the engine is nearly silent and uses water as a lubricant instead of motor oil.

Schoell’s invention, the Cyclone Green Revolution Engine, is on display this week at the Small Engine Technology Conference sponsored by SAE International and SAE Japan at the Midwest Airlines Center. The event is not open to the public.

Although it’s still in the research-and-development phase, the engine won a prestigious award from SAE International, formerly the Society of Automotive Engineers. This summer, Popular Science magazine named it one of the year’s top 10 inventions.

The Cyclone is a radical makeover of the steam engines that once powered locomotives. It works by injecting and burning fuel in a combustion chamber that’s a high-tech variation on the boiler that powers traditional steam engines. The fuel-air mixture spins inside the chamber in a cyclonic motion as it burns, increasing combustion efficiency and reducing tailpipe emissions.

The combustion process boils deionized water until the resulting steam reaches what’s called a “super-critical” state of about 1,200 degrees Fahrenheit and 3,200 pounds of pressure per square inch. The steam’s intense pressure drives a piston engine, variations of which are adaptable for everything from lawn and garden equipment to ships and submarines.

The engine is designed to conserve heat and convert it to power rather than give it off as waste energy like an internal combustion engine. Even heat from the exhaust is collected with heat exchangers before the waste gases are released to the atmosphere, according to company literature.

A Cyclone can run on almost any gaseous or liquid fuel, including ethanol, biodiesel and propane. One version of the Cyclone uses solar power and also can run off of the waste heat from internal combustion engines, the inventor says.

The engines have been run on biofuels derived from palm oil, cottonseed and chicken fat. They’ve also run on a “fuel cocktail” made from a mixture of kerosene, gasoline, alcohol, biodiesel and diesel. Even solid fuels such as pulverized coal, algae and orange peels have been used successfully, Schoell said.

“With a Cyclone engine, you could fill your tank with any fuel mixture that’s inexpensive or abundant at the moment. The choice could eventually give consumers some leverage over the oil monopolies,” Schoell said.

The engine runs cleaner and more efficiently than an internal combustion engine, according to Schoell, a 65-year-old entrepreneur from Florida who has been an inventor since he was 12 years old and had his first patent at age 18.

It’s very quiet and never needs oil changes.

“You could mow your grass at night and the neighbors wouldn’t even hear the engine,” said Frankie Fruge, chief operating officer at Cyclone Power Technologies Inc., the Pompano Beach, Fla., firm developing the engines.

Simpler, cheaper to build

By eliminating many systems such as oil pumps, radiators and catalytic converters, a Cyclone engine could cost less to build and operate than an internal combustion engine, according to Schoell. The engines could be built in a wide range of sizes for household or industrial use.

Some of the first commercial applications could be available in less than five years, Schoell said, adding that he believes high-tech steam engines could someday replace internal combustion engines.

“It’s based on need. Sometimes you invent something because it’s a neat thing but you don’t have a customer for it. But when we started this company four years ago, we could see there was a need” for an alternative to gasoline and diesel engines, he said.

Variations of external combustion engines have been around for decades, widely used in applications such as power plants and submarines. What’s been difficult is scaling down that technology for uses such as automobiles and home generators.

“I am a bit skeptical that it’s a good fit,” said Chris Damm, associate professor at Milwaukee School of Engineering.

“We have been making internal combustion engines in this country for 100 years, so engine manufacturers have a big head start,” Damm said. “Any time that you are starting something from scratch, it’s hard to compete.”

The U.S. and British military have shown interest in the Cyclone because they want engines that can run on a variety of fuels.

Raytheon Co., a major U.S. defense contractor with $2.3 billion in sales last year, has awarded a research and development contract to Cyclone Power Technologies, with Raytheon providing money, equipment and personnel.

“We see great potential in the Cyclone engine for many of our customers’ applications,” Kevin Bowen, an engineering fellow at Raytheon, said in a news release.

The Cyclone is still in its infancy. Friends and family of the company’s founders, and angel investors, have provided several million dollars to keep the research going.

Executives at Briggs & Stratton Co., world’s largest maker of small gasoline engines, said they know of Schoell’s invention although he has not contacted them about it.

“The long and short of it is that we have cost and complexity concerns using this type of approach in the markets we serve,” said Laura Timms, a Briggs spokeswoman.

The engines still need some refining, Schoell said, but mostly only minor mechanical issues remain.

He added: “A lot of this is brand new, and anything new is difficult to do. But I can envision trucks going down the highway powered by a mixture of coal, gasoline and biofuel . . . and you could grow algae on top of a pond, use that for fuel, and raise catfish in the same pond.”
