April 2005 Newsletter

While searching the internet I found an outstanding site called the

Phoenix Turbine Builders Club.

Below is an extract from one of the monthly reports.

May 2003

I am back again with more nozzle experiments. Last fall in the members forum James Morris described a method on how to design a convergent/divergent nozzle for optimum performance. Knowing that my nozzle design was basically a hit or miss approach. (Actually more miss then hit.) I decided to try his advice.

Briefly he stated that the convergent inlet to the throat of the nozzle should have a radius that is at least three times the height of the throat and that the angle of the divergent portion of the nozzle should be determined by adjusting this angle to give the lowest possible temperature reading when measured at the output of the nozzle. (His full description can be read in the members forum archive. 10-12-02)

Armed with his knowledge plus checking my engineering handbook I decided to build a test nozzle that had both an adjustable throat and a divergent output. I placed a thermocouple at the output of the nozzle to measure the temperature and also aimed the nozzle to blow on the top of a small postage scale. With this setup I ran a number of tests with different size throat openings and with different lengths for the divergent portion of the nozzle.

Using a regulated air supply then starting with the nozzle set to zero degrees and slowly increasing its angle the results clearly showed the temperature dropping and at the same time the air pressure on the scale increased. Once the lowest temperature and maximum pressure had been reached further increasing of the angle caused the temperature to rise and the pressure on the scale started to drop.

Originally I planned to try to make a chart that could be used to look up the correct angle. However after making numerous test runs I discovered that having the precise angle is absolutely critical to achieving maximum efficiency and in all my tests this optimum angle only varied from about 1 to 3 degrees. At that point I found it impossible to measure the angle accurately enough to be able to make a useful chart. I then moved onto plan "B" and concluded that the best approach would be to design a new nozzle for my turbine in which the divergent portion would be adjustable.

After constructing a new nozzle I "Tuning it" for best performance by taking its temperature and then mounting it on my original test turbine. I got the following results.

In previous tests with my original nozzle and starting with air at 105-PSI and dropping to 80-PSI the maximum no load speed I was able to obtain was 6780 RPM.

With the new super nozzle the maximum speed is now 20000 RPM! Thus proving beyond any doubt that my original nozzle was a piece of junk.

I reduced the air pressure to a regulated 50-PSI this caused the maximum speed to drop to 18000 RPM. Next I applied a load to the turbine slowing it down to 9240 RPM. At this speed the turbine produced approximately 27 in/oz. of torque or about 3.9 HP.

Recalling the results that I got with my multi-nozzle turbine a couple months ago I obviously had to try the new nozzle design in a multi-nozzle arrangement. To do this I then made two additional nozzles and mounted them on my original turbine. (Total of three nozzles 120 degrees apart.)

Using the same air pressure as before the maximum no load speed stayed essentially the same but the acceleration time was cut in half.

Appling a load to the turbine I slowed it down to 10200 RPM at which point I measured approximately 80 in/oz of torque that calculated out to about 13 HP.

Attached is a drawing with a half sectional view of my nozzle showing its internal configuration and size.

Finally I would like to thank James Morris for his contribution. It is the piece-by-piece gathering together of information like this that will hopefully make the Tesla turbine into a practical engine. (Editor: Read James' 6/1/03 explanation of thermodynamics in the PTBC Forum)

What we need now is for someone to develop a method of say burning waste oil in an ultra-clean manner so as to fire a flash tube boiler.

Richard Gideon

This is an excellent piece of engineering work. It clearly unlocks one of the mysteries of the Tesla turbine. Tesla mentioned that the efficiency of his engine was dependant on the design of the inlet and outlet nozzles -- this experiment clearly shows the relationship between maximum gas velocity and maximum turbine speed, horsepower, and efficiency.

Other members may find additional nozzle information at their local libraries under: "steam turbines".

Nice job, Richard!

complexities of a "two chip micro controller" for a therapautic ultrasound unit that he had designed.

Robert ... had brought along a "Q2" Energy Ball / Spa Unit. It produces ionized water that rebalances the body energies, reducing
ailments such as depression. The units are made in Toowoomba, Australia, and can be seen in detail on the internet by conducting a
"Google search" on Q2, Australian pages. Devashoen tried the foot spa out.

Devashoen ... produced a bottle of "Grainfields" liquid organic food, rich in lactobillus. He recommended it as a worth while supplement.
Robert ... Described an article by "Robert O Becker" on the band of frequencies (everyday electrical pollution) that has detrimental
effects on humans.

Michael ... produced his partially completed water project. He had purchased a Stanley Meyer Patent #4,613,779, Electrical Pulse
Generator and he is trying to replicate it and build a water dissociator, using pulsed high power LED's, resonance and pulses.

AndrewS ... discussed "Superior Plastics Recycling" in it's continuance on from the failed "Omnipole" .The factory is in the Collex
Waste facility, Churchhill Road, Kilburn (South Aust).

Devashoen ... had a tripod with hanging shapes suspended from it .They were constructed on Fibonacci dimensions and had special
oscillatory properties.

Ken ... said that he had posted a recipe for a health tonic on the ASTRO Webb site. He had been given a CD full of concoctions and
would post some of them on the member's pages.

The meeting closed at 10.37pm, followed by supper.

Hybrid Locomotive Gains Traction 

By Stephen Leahy
 Hybrid cars, trucks and buses have already hit the road. Now, make way for the Green Goat, the world's biggest hybrid. It's a 2,000-horsepower locomotive that radically reduces fuel consumption and emissions of pollutants.

The Green Goat is a diesel-electric hybrid in which the normal massive diesel locomotive engine is replaced by a 290-horsepower inline 6-cylinder diesel truck engine and a 600-volt battery bank. The batteries supply the power needed to drive the electric traction motors on the wheels of this 280,000-pound "goat."

 Goat is railroad lingo for the smaller locomotives used for moving rail cars around over short distances.

RailPower Technologies, developer of the Green Goat, believes the hybrid locomotive is an ideal way to reduce fuel costs and air pollution in switching yards, said Simon Clarke, executive vice president of the Canadian company. RailPower says the Green Goat uses 40 percent to 60 percent less fuel and emits 80 percent to 90 percent fewer pollutants than conventional train engines.

To build the hybrids, the company strips older locomotives of their engine and cab but keeps the same frame, fuel tank, brakes and electric traction motors. Then it slaps in the long-life lead-acid battery bank. RailPower Technologies says the added weight of the batteries actually helps improve the Green Goat's pulling power, which is rated at 2,000 horsepower -- enough to pull 88 rail cars.

The hybrid is mostly an electric locomotive; the diesel engine only operates to keep the batteries at their optimum level of charge.

A day in the life of a typical railroad goat involves pushing heavy loads short distances at low speeds, making frequent stops and sitting in idle mode 70 percent of the time waiting for someone to sort out which rail car goes next.

Robert ... opened the meeting at 8.12pm. Appologies from Athol, Ken and Mathew and the Guest Speaker.
Robert announced that the meeting would be a general meeting and he started off with a short movie on Royal Ramond Rife isolating, culturing and killing (with a plasma discharge) the "Breast Tumor" virus. We saw Rife using a neon - argon light to stimulate the growth of the virus (cut from a freshly removed breast tumor) and use his very powerful self built microscope to view the virus and watch their death under the plasma discharge. He commented that "every breast cancer virus had been killed in a 10 miule radius" (by the R F plasma discharge).

Joanna ... commented on the "Purple Grape" cancer cure that uses a compound in the grapes called "reversitrol" to tackle the cancer.

Robert ... said that the Perth based Dr. Holt used glucose to cause the cancers to open up to the 434Mhz RF UHF radio therapy treatment (based around Rife technology).

Dino ... said that there had been an 8.1 earthquake at McQuarie Island three days before the Tsanami. He had several seismographs of the tsnami causing earthquake on which he pointed out the peculiar oscillations that lead up to the tsanami causing quake. He said that there were many speculation as to the cause of this quake, from scalar weapons to the possible pull of the enigmatic Planet X's 26x earth's magnetic strength pull. He said that the earth had developed a wobble around its axis as a result of these quakes.

Dennis ... said that he had been over at Edithburgh fishing, the day after the tsanami and that he had noticed an abnormally low tide and that the tides were all messed up for the next five days.

Robert ... mentioned an article expounding the nasty toxicity of "Roundup" weedicide and then described a CD that he had purchased from ARE (Associated Research Enlightenment) on Edgar Cayce's 14,306 readings. He said that Sidney Sheldon had been asked to do a biography on Cayce. He had started out as a sceptic, but was utterly converted after his research. The CD's were originally priced at US$200, but were now priced at US$50.00.

Dino ... said that there was a Webb site in USA called "" where you could buy things in the USA and they would charge an extra US$5.00 + postage to send it over here.

Dennis ... Fischer & Paykel Wind Energy Group ... had on demonstration three different types of PVC wind generator blades that he had made. He went through the attributes of each type of blade. He said that as blades pick up their speed from the tips they had to be fine pointed. The blade base angle needed to be between 25 to 30 degrees. He said that for more good information on propellor design, one should look up "Morelock Engineering, Queensland Australia"  on the internet.

Dino ... said that prior to the Tsanami, animals knew and had left the area. He said that he had seen a TV show on wild crocodiles having a harmony pact with Indonesian villagers. They talked to the crocodiles, swam (harmlessly) with them and made lifelong friends with them. He said that a 14 year old girl had told him to talk to the flocks of maraudering Lorakeets that were wreaking havoc on his 40 apple trees. He asked them to come only in small groups, not in swarms. It worked and the small groups did not wreck the trees!

Robert ... mentioned a book called "The Field" by Lynn Taggart, where she talks about the "zero point field" where time does not seem to exist. He also mentioned a worth while movie that was soon to be released in Australia, called "What the XX@ do we think we know" It is a hybrid docu - drama. It can be previewed at

Peter ... mentioned a free Ebook offer "Medical Miracle" on hydrogen peroxide and its many medical misconceptions,courtesy of Dr. William Campbell Douglass II, from A printed copy of this book was presented (with thanks) to the ASTRO Library by RobertN.

Robert ... then showed a brief movie on BenQ, where his staff accidentally over diluted a preparation of heparin. It worked the same as the full strength sdhould have and thus discovered homeopathy!

RonE ... produced an ingenious illuminated stand for book digitising by photographing and OCR copying.

Devashaon ... demonstrated his huge teepee style tripple funnel water vortexing unit. It was marvelous!!!

The meeting closed at 10.50 with supper.
