Adelaide Branch

Welcome to the July edition of the ASTRO SA Inc. newsletter. Don’t forget that the next meeting will include the A.G.M. for the purpose of electing our office bearers for the next twelve months. I can still remember the deafening silence during last years elections, so please get involved and put something back into the group.  


The meeting began at 8.05pm with a new attendance record of 54 people. If this number continue to turn up for our meetings, we will have to take the step of holding them in a hall. We have attempted to avoid this option in the past due to cost considerations. Ashley began the meeting by welcoming everyone and Dan followed with the Treasurers report. The correspondence for this month included the ASTRO programmes for the NSW and VIC groups.

The general part of the meeting began with Ashley presenting several articles covering almost everything from colloidal silver to instant enlightenment. Dino gave details of a spiritual workshop being held at his farm, and Anton donated to the ASTRO library the first lot of data from UFO researcher Bob Bartholemew. Speaking of donations, thanks to Ben and Desiree, who gave the group a video machine to use at meetings. (after Roger fixes it!) Andrew then gave a presentation on a water purifier which he is making available to ASTRO members at a reduced rate. Still on the subject of water, Dan is looking for people to assist him on a water related project and finally Michael talked about an article in, New Scientist magazine regarding a 5Okw solar power generator.

David French, our guest speaker then gave his talk which judging by the number of questions asked was very well received. David began by talking about PH levels in the body, what happens if they get out of balance and how to maintain them. He then went on to the subject of Rife and other frequency machines and his experiences in using them. Finally he spoke of the work that is being done in WA on a device that collects energy from the atmosphere. This technology is planned to be released in the next 6 months and is said to be capable of powering anything from a mobile phone to a factory.

The meeting concluded after the videos that Erika kindly brought along were shown and the last people were evicted after the curfew time of midnight. 


Thanks once again to Leon for this series of articles on flat plate collectors.

The glazing allows visible short wavelength light to pass through to the absorber plate and prevents passing air currents from drawing off much of the collectors heat. It also keeps the longer wavelength radiation from escaping back into the atmosphere. It is this property of glass and some types of fibreglass and plastic that creates a “greenhouse effect” inside the collector. Everybody knows what it is like to get into a closed car on a sunny day, the heat can be unbearable.

Any enclosed space behind glass, whether inside a car, a greenhouse, or a solar collector will gather and hold considerable amounts of heat energy. Short wavelength sunlight comes through the glass and is either absorbed by or reflected off the collector plates (absorber). Rays that are re-radiated cannot pass back through the glass to the outside because their wavelength is made longer once they hit some surface. In other words, a ray that bounces off an absorber plate has a longer wavelength than it did before it hit it. These longer waves reflect off the inside of the glass and bounce back and forth inside the air space. In this way a little radiation can be enclosed to become a lot of heat.

The drawing shows that when short wavelength rays hit the absorber plate, some of their energy may be re-radiated back, but their intensity is weakened, meaning that their wavelengths become longer. Because they can’t pass back through the glazing, they hit the absorber again and again, thus giving the plate several chances to absorb them.

There are basically four factors that affect the performance in regards to the amount of heat captured by a flat plate collector.

1.         The solar intensity “insulation”.

2.         The collectors orientation toward the sun.

3.         The temperature of the surrounding air or “ambient air temperature”.

4.         The materials used in the collector itself, specifically the quality of the glazing material plus the material selected for the key component, the absorber plate.

Next month we will look at the question of “How efficient are Flat Plate Collectors?”


Speaking of solar and sun, what commonly used phrase does the following arrangements of letters represent? Answer is on the back page!



Acknowledgement is hereby given that the following articles on the “Magnetic Pulse Motor” and the “Hybrid Power System” are taken from the TEBA Membership Manual. Their address is 5464 N. Port Washington Road, Suite 293, Milwaukee, WI, 53217.


This design by Japanese engineering firm, Kure Tekko, first appeared in Popular Science magazine back in 1979! It is similar to the Adams motor in that it only requires a pulse of energy when the rotor magnets are close to the stator electromagnets. Both the rotor and stator  have north poles facing each other, and all that is required after the motor reaches 200 rpm is a short burst of properly timed power from the electromagnet. Once the rotor has entered the field, it is propelled to the area of lower flux density represented by the mechanically expanding scroll of permanent magnet material. As the distance of the magnetic scroll is increased the magnetic lines of flux decrease. This represents an area of less north and the rotor is literally squeezed out of the magnetic region. This brings the rotor full circle and it is time to send another pulse of electrically generated flux. This forces the motor’s rotor, which is attached to the output  shaft, back into the magnetic region and the process repeats itself. The only input energy required is short duration pulses.

Since the pulse motor was announced in 1979 there has been a significant improvement in magnetic materials making this device even more attractive. New magnets (e.g.Takahashi) have been introduced which have extremely high Tesla ratings that were unheard of when this motor was first announced. There is also a new metal available, developed by Allied Signal called Metglass, that has no magnetic permeability or memory. This can be used in the electromagnet to eliminate saturation effects and reactive losses that occur in high speed pulse switching. The core of the electromagnet does not retain any magnetic charge, allowing the induced field to immediately collapse after excitation current is removed. The collapsing field can then be removed and stored in a capacitor, using simple steering diodes, for reuse on the next switching cycle, further reducing power input requirements. Simple high speed power switching is now available with a new generation of high power transistors, replacing the mechanical distributor used originally in the motor, and will provide for extremely high operating speeds.  


The following hybrid design for a motor vehicle uses a Tesla engine to provide unprecedented performance with full low end torque while allowing the pulse motor to give tremendous mileage at highway speeds. In one possible combination, the Tesla engine is coupled to a high frequency alternator, providing power for the vehicles electrical system and pulse motor. The alternator and Tesla engine are on the same shaft and are coupled through a Tesla transmission to the pulse motor. The engine operates at a fixed high speed in the tens of thousands rpm range for highest efficiency. The unique gearless transmission, which is a variation of the Tesla engine design, converts this high speed to controllable lower speeds with high torque and can provide power beyond the rating of the pulse motor. After the engine is started and up to speed, fluid is introduced into the transmission, turning the pulse motor, which requires 200 rpm to start. After the pulse motor is started, the transmission is disengaged and only electrical power is provided, unless heavy loads require direct engine assistance. This allows a fuel sipping, economy miser, conversion to a monster horse power, muscle machine, almost instantly on command!


The Tesla engine’s main components are nothing more than a series of flat discs, which besides being the active elements of the Tesla combustion engine, can also act as a flywheel for the pulse motor. Unlike a normal gas turbine engine that has fan blades in it’s compressor section, the Tesla pump has no such encumbrances, using instead laminar flow bladeless elements or discs that represent proportionally lower load as the input air to the compressor is throttled back for an idling condition. When input air is removed, the compressor represents almost no load to the engine, drawing in a high vacuum. This configuration would not be possible with a conventional bladed type turbulent flow compressor section which would continue to load the engine and shaft, creating unacceptable parasitic drag.

Volvo has recently introduced a concept car which uses just this principle but is using a bladed turbine engine coupled to a Tesla high frequency generator which feeds an electronic motor drive control to adjust the frequency and therefore the speed of a Tesla polyphase induction motor. This full size concept car by Volvo is reported to perform very nicely while at the same time attaining 45 mpg at a speed of 55 mph. Volvo has coined the car as “The Environmental Concept Car” or ECC. The only mechanical part of this system that is not Tesla’s is the turbine engine. Tesla claimed efficiencies for his engine, without the benefit of the electric drive intermediary, operating alone, that would match the performance of the Volvo ECC. Tesla made claims, based on actual test results, that the engine would achieve an efficiency of 60% at the shaft when used with gasoline. That is about two to three times what our piston engines of today are capable. Tesla’s engine would also require almost no maintenance, require no crankcase oil and would operate for millions of miles if high quality main bearings were employed, which are the only wear prone component.  


Chinese researchers have found that by using petrol and hydrogen fuel mixtures, engine pollutants were reduced and fuel economy was increased using lean mixtures of both fuels. The engine the tests were carried out on was a Chinese made “492 Q” which is a 4 cylinder, 4 stroke, water cooled engine of 612 cubic centimetres capacity.  The petrol was fed into the engine via a conventional carburettor while the hydrogen was mixed externally with air and supplied at a constant rate of 750 grams per hour. Carbon monoxide emissions decreased with the percentage of hydrogen used. The amount of hydrocarbons in the exhaust depended upon fuel temperature and the quenching effects of the condensed fuel layer on the cylinder wall. Incomplete combustion due to these and other factors increased hydrocarbon emmissions. Increasing the fuel/air mixture reduced hydrocarbons up to the stoichiomatric ratio. (the mixture at which all the air and fuel are reacted) Beyond this point the mixture is excessively lean at which point it burns more slowly and also contributes to incomplete combustion and hydrocarbon output. Nitrous oxide emmissions are reduced by lowering the amount of oxygen in the fuel mix and reducing the temperature and duration of combustion. Reducing oxygen also increases hydrocarbon emmissions, so a balance between the two pollutants has to be found although rapid burning can reduce both.The conclusion that researchers came to was that adding a small amount of hydrogen to a petrol/air mixture can make rapid burning and an improvement of emission characteristics possible.


Electrolysis is the process of producing hydrogen and oxygen from electricity and water. Water is a molecule which consists of two atoms of hydrogen and one atom of oxygen which are electrically attracted in a chemical bond. When an electric current passes through water, the chemical bond breaks down and results in two positively charged hydrogen atoms and one negatively charged oxygen atom. If two oppositely charged electrodes are inseted into water and a current is passed between them, the negative oxygen ions migrate to the positive electrode and the positively charged hydrogen ions are attracted to the negative electrode.

The electrical resistance of water is high, about 100 ohm/cm. This resistance can be lowered chemically by adding a salt (sodium chloride),an acid (sulphuric acid) or an alkali (sodium hydroxide). Salts and acids are more corrosive and are normally not used because of this. The two most common electrolytes are potassium hydroxide and sodium hydroxide. Sodium hydroxide is less conductive but cheaper than potassium hydroxide and so is economically more attractive.Ideally distilled water is used as electrolytes produce chlorides and sulphates in the presence of tap water impuities. These chemicals slowly corrode the electrode material although in practice 314 stainless electrodes and tank water seems to work OK.

The hydrogen and oxygen can be collected as a combined gas as in “Browns Gas” or individually by using separators. These are normally membranes or diaphragms between the anode and cathode to keep the gasses apart. Materials such as artificial fibre cloth, rubber cloth or metallic mesh can be used. Remember that if the gasses are not separated there is a substantial risk of explosion as mixtures of between 4% and 75% hydrogen in air and between 4% and 94% of hydrogen in pure oxygen are explosive.  

The minimum voltage required to split water is theoretically 1.24 volts. Efficiency is typically 35% at this voltage. Some commercial electrolysers operate at 1.9 volts with a cell efficiency of 65%, while some advanced cells using platinum electrodes are up to 73%. However as with most things there is a trade off in that above 1.48 volts, the cell begins to produce heat. This point is called the thermoneutral voltage. The graph shows the range that the cell operates most efficiently. This is the area between the thermoneutral voltage (upper limit) and the reversible voltage (lower limit below which no hydrogen is produced) where the electrolysis reaction absorbs the heat. In general lower voltages and higher temperatures mean improved efficiency.  

A pair of electrodes in a container of electrolyte makes up one cell. Individual cells may then  be connected in series or parallel. In series connection, each cell shares an electrode connection with the next cell (see diagram) while in a parallel connection, each cell’s anode (positive electrode) is connected to the positive supply while each cathode (negative electrode) is connected to the negative supply.

Advantages of using a series connection are supply can be high voltage and low current, less floor space due to thinner cells, all cells share a common electrolyte bath allowing freer circulation of the electrolyte. Disadvantages are that high voltage and low current combine to give lower current efficiencies, each cell must be identical to avoid overloads giving higher initial costs.

Advantages of using a parallel connection are that individual cells can be isolated without affecting neighbouring cells, a higher current density is possible resulting in densities approaching 100%, and a longer service life is possible. (25 years or more) Disadvantages of a parallel connection are because of the low voltage and high current, large electrical conductors are needed to keep the electrical resistance low, more floor space is required because each cell is separate and there can be problems with lack of electrolyte circulation.



This will take place first, for the purpose of electing next years committee members. This is normally a very brief event, usually only extended by the lack of volunteers coming forward. (There always seems to be something really interesting up on the ceiling that people keep looking at!) So lets keep it short and then we can get on to the interesting part of the evening which is the.......


This month’s meeting will be held on the second Friday of the month once again, this time being: FRIDAY JULY 12TH.

This month we will have our very own Ashley and Alan continuing on from last month’s talk by David on using frequencies in healing. Our dynamic duo will show what frequencies and harmonics are all about in this audio \ visual demonstration.

We will also show a short documentary on how Alternative Energy is creeping into the lives of the major power producers in England. This recent video which deals mainly with wind, water, and solar power, is about some quite major projects that have been undertaken in this country in their effort to reduce the pollution caused by coal fired power stations.

Just a reminder not to forget your $3 entry and something to share for supper. It should once again be an interesting night so I hope to see you all there!
