Directory: Ralph A. Davis: Whirl Power Turbine

From PESWiki

Jump to: navigation, search

Allegedly using principles of a tornado or vortex, the WhirlPower rotor invented by Ralph A. Davis is propelled by continuous combustion using any compressed fuel, including hydrogen or compressed air. When oxygen enriched air is combusted with hydrogen a discharge of H2O2 hydrogenperoxide could improve the atmosphere we breath.

This engine is said to capture most of the energy in flowing gases and delivers power to a rotating shaft in proportion to the fuel input. The engine has only one rotating part, and does not need a transmission; hence the pollution and cost in manufacturing the motor will be reduced to one tenth. A similar reduction in pollution and cost is expected in the device performance.

"This is a True Rotor Power utilizing centrifugal force as well as compression and velocity for various RPMs and torque output." -- Ralph A. Davis (Oct. 2, 2007)
No decent prototypes have yet been built to fully prove this concept. Prototypes thus far have been crude and inadequate.

How it Works

The turbine contains rows of corrugated flanges. The fluid takes a hold of the flanges and turns the turbine. The turbine allegedly starts spinning with even low gas flow, producing high torque at even low rpms.

"A practical size rotor for experimenting would be a stainless steel kettle 10" dia. x 6" long? Some power units are 1hsp = .7455 kw = 42.4 btu/min."


The following text is from a formerly private document, now (Oct. 3, 2007) made public with the inventors permission.

Description; by Ralph A. Davis, Inventor; 2005

Now that you have taken a look inside this Rotary Engine, which I called an Ecomotor and Ecoengine, we realize that considerable Engineering must be done to build a perfect power unit. But for a demo, most any tin can mounted on a shaft and bearings like the picture on my home page, produces exciting action the like of which was not known to the world until now. The can was sliced in sections perpendicular to the axis or shaft and flanges crimpled with pliers forming small Venturi like indentures that obstruct the circular flow of gases and capture some force to turn the entire rotor. When this is repeated enough times over multiple flanges, all of the flowing energy is delivered to the rotor and shaft. In each stage of this process, the gas flow is resisted, and the molecules overflow to the next stage. Now, so that they don't get away, we have the circular buffer troughs cooperating with the flanges to direct the flow centrifugally into the next flange.

An alternate rotor construction for production is possible using circular corrugated metal (stainless steel) with spaced indentations, which form Venturi passages, which restrict the flow of gases and cause intermittent multiple pressure and expansion, acting on the rotor for power delivery. This must be matched with the inner grooved or corrugated buffer to redirect gases to the next stage of circular power collector. Guide vanes close to the inner surfaces of the rotor direct the body of gases flowing into the circular path. They may be adjustable mechanically for varying volume and pressure.

So to make all this happen, pressurized gas is needed. many types of fuel are available. This part is not new or novel. Any combustion engineer or auto mechanic can rig this up. When burning hydrogen for fuel in air with water spray, expert sensing and computer control is required, but it is the road to cleaning our environment. The hydrogen tank can encompass a neoprene bladder for insulating the water from the weather, also equalizing the pressure.

Water spray will use up some excess heat and boost the pressure and power. At 350 Degrees F, the mist droplets will explode 1700 times in size. The second drawing shows a configuration to capture the steam and direct it into the gas flow. There will be some heat loss through the surface of the rotor. When the temperature of the rotor surfaces drop below 212 F, condensation may occur; and small drain holes are needed through the flanges, so centrifugal forces can throw the water out. Once again some engineering is needed for controls to regulate the input flow, RPMs and shaft power output.

Difference from Tesla Turbine

On Nov. 7, 2007, Ralph Davis wrote:

We are having confusion about the difference between Tesla Turbine and Whirlpower. Tesla wastes energy with a stationary housing containing the fluid pressure with discs on a central shaft for capturing energy by friction..

Whirlpower has a rotating housing with inward flanges to capture the energy delivered by centrifigal force from the fluid. Even in the static position it produces instant torque compared to Tesla which requires increased RPMs.

Company: n.a.

Not formed yet

Inventor: Ralph A. Davis

86 years old in Nov. 2007, but in March 2008 The V.A. Hospital renewed his youth and he expects to be around for many more years.

"Many things I have dreamed of have come into being later [by others].

  • the chain saw
  • the escalator
  • Linear turbines to harness river currents
  • a hydrogen filling station

"But I enjoy seeing them in use anyway!"

"Every day, every hour, I am dreaming of a power That can change your world and mine. Got to build that power before the world goes sour And breath fresh air again!" Author RAD 1969.

Davis was a Marine Pilot, college educated with knowledge of Modern Business from Alexander Hamilton' course. Served on the board of directors of three Corporations. While being a member of the Future Millionaires Club, he saw the need to improve the Economic System to make it more manageable, and founded ReEconix.

Davis says he has some motor and fuel research knowledge of combustion, and could use someone with strength in that area to develop this technology properly.

Holds Promise

On Oct. 2, 2007, New Energy Congress member, Sterling D. Allan wrote:

It seems that the inventor has languished for lack of interest and funding, but he has a very good concept, which has been roughly demonstrated with two crude prototypes.

His concept is definitely superior to previous turbines because it uses centrifugal forces which other turbine waste.

Davis is young for his age so I would like to see his good skills and enthusiasm make progress toward reducing the pollution and need for fossil oil and coal. It holds great promise, in my estimation.


On Oct. 4, 2007, 6:00 am, Sterling D. Allan added:

I had an interesting dream this morning that seemed to associate the release of this technology to the kind of intercessory work described in the new TV series, "Heroes", which came out via the "Watch it Now" capability at Netflix in the last day or so. In that series, a group of indidividuals with extraordinary gifts coincide to avert a nuclear blast in New York City.

I believe the following statement to be an axiom: "If we as a human race can pull our act together, we don't have to end in destruction."

Regarding saving the world, we (PESWiki) were given permission from Ralph A. Davis yesterday to post his rudimentary plans here on this page. In so doing, he could be jeopardizing his ability to get a utility patent. That is a big leap of faith he's made.

Let's step up and make it worth his while. If his concept is plausible, let's help him promote it; and he would certainly deserve a just reward.

Not to be Confused With . . .
