Welcome to the October edition of the newsletter. There has been plenty of activity again this month with water being the main interest once again from several aspects. The sub-groups mentioned in these notes last month were formalised at the last meeting with names and phone numbers being placed on the whiteboard. I guess it is up to someone in each group to take the lead and start organising some gatherings. Will that be you????? ..................Bruce
SECRETARY’S REPORT - SEPTEMBER MEETING
A pot purrie of videos and talks was introduced by Ashley. Our treasurer reported that we have $670 in the bank. Next month’s guest presenter will be Rebecca Hall with her talk entitled sound for healing. Herman from the dowser’s club shared his 2D image of a pyramid for energising objects. Splinter groups for concentrated efforts [or more cooperative] on Cars, Water, Mechanical and Car\Fuel were formed. Roger showed us his “The Force” economiser for cars. Andrew S showed us his water energiser and explained how the principles of vortexes and magnets can work on water. We finished off with Eugene Brisian explaining about Bitron additives and Keith donated a book to the library containing descriptions of 17 to 20 carburettor’s for fuel economising. ...............Andrew
OXYGEN ENRICHED AIR
Having trouble staying awake at ASTRO meetings? Maybe the technology in this article from New Scientist (August 1997) is the answer. In Las Vegas casinos, extra oxygen is pumped into the air to keep the gamblers awake. Toyota is now patenting a system which does a similar thing to prevent drivers from falling asleep at the wheel of their cars. Air from outside the vehicle is sucked into a cylinder that contains a magnetic field. Oxygen is paramagnetic, so it moves in line with the field and through outlets into the car’s cabin. Nitrogen is diamagnetic and so remains at the centre of the cylinder where it is released back into the atmosphere.
This is an interesting concept of using oxygen’s magnetic properties to separate it from the rest of the air. I wonder if a similar thing is happening in the water treatment units that use magnets?
UNITY OUTPUT VIA MODIFICATION TO STANDARD MANUFACTURED ELECTRIC GENERATORS AND MOTORS
This article came from Keelynet and describes in general terms how any electric generator or motor can be converted into an overunity machine. Whether it has actually been done or is just a theory remains to be seen. The principles are similar to those employed by some members of ASTRO in their experiments and have shown promise although have not as yet been able to be self sustaining. (Unless someone out there is keeping a secret and hasn’t told us!!!!)
“The standard manufactured electrical generator systems can be modified inexpensively to the Over-Unity design concept. By the addition of a second set of commutator brushes and/or the addition of a second slip-ring assembly in the present electrical generators, Over-Unity output is achievable in a matter of hours. These additional elements are to collect (scavenge) the collapsing fields (C.E.M.F.) of both the armatures and field coils of present electrical generator sets. Present electrical generator designs throw away this tremendous amount of valuable electrical energy in the form of C.E.M.F.
On the armature/exciter element, install a second set of brushes or sliprings, the exact amount behind the driver units needed to collect the C.E.M.F. of the armature's field collapse, to take it out of the system for utility. On the field coils system, install a second set of brushes/slip rings, the exact amount behind the original primary field coil system needed to collect the C.E.M.F. of the field coils' collapsing fields for utility when taken out of the unit.
The additional new C.E.M.F. outputs can be phased to the original output system in the load wiring. These modifications far more than doubled the generator's output power at small modification costs, and at no increase in operating costs. This general design modification allows almost any currently manufactured electrical generator set to be an Over-unity design. With some additional external modifications, a self running or stand alone Over-unity configuration can be achieved on most commercial electrical generators. As most manufactured electric motors can be made into electrical generators the above type of modification can be done to these electrical motors.”

Due to the underwhelming response (like...nothing!) from last month’s request for articles on any local activity, I am putting it in again this issue. So, LET ME KNOW WHAT YOU ARE DOING!! Any feedback on articles would also be appreciated. I would like to thank Roger, Roger and Robert for articles of interest that they have found in newspapers and magazines and passed on to me for inclusion in the newsletter.
This month, not something you would really want!
TESLA TURBINE / PUMP
How Does It Work? How can a disk with no blades possibly work as a turbine? Well, there is a simple experiment you can do to see what is happening. Many of us are familiar with a pizza cutter, which is circular blade which rotates freely on a handle, for cutting pizzas. Now, just hold this where a stream of water is striking the edge of the disk -- voila! The disk turns. The viscosity of the water drags the disk along, imparting power. This drag is due to the boundary layer of fluid right on the surface of the disk.
Improvements: Tesla first came up with the idea for his bladeless turbine watching just such a disk in a stream. But then, of course, he thought about it and made some modifications. The first one we might think of would be to increase the number of disks. This would increase the surface that the boundary layer could act upon. Secondly, there is the fact that our pizza cutter only uses a part of the disk the fluid is striking, and then the stream goes outside the disk area and down the sink. If we could enclose these disks so the fluid stream goes all the way around, that might be better. Then we have to figure out where to let the fluid out. If we cut some holes near the centre of the disks, so the disks are connected to the axle by flat "spokes", the fluid could exhaust out the centre. These changes are just what Tesla came up with.
Now imagine if you take a series of disks like this with the holes cut in the centre, and rotate them very fast with some kind of motor. The fluid in between the disks is dragged along the direction of rotation, and the centripetal force will fling it out along the periphery of the disks. With an appropriately shaped easing and flute to turn the velocity of the fluid to pressure, you have a bladeless pump.
The above information can be found at "http://phyhepsunl.ucr.edu:80/-boswell"
Meanwhile, a new boundary layer turbine driven pump and generator is soon to be on the Australian market. This is a joint effort between a Victorian and Queensland company. The photograph shows one of these units with the turbine easing on the right housing a set of turbine discs like those on the left. Fuel is injected into the top of the casing and ignited by the sparkplug. Once the turbine has warmed up, the fuel ignites as it is injected and the turbine runs completely unaided. The inset shows two pump rotors. Note the much larger spacing between their discs compared to the turbine rotor. It looks like Tesla turbine technology is finally coming of age!
FORD ENVIRONMENTAL REPORT
Exploring The Alternatives To Gasoline:
Methanol. Ethanol. Electric. Natural gas. Propane. Ford is exploring these five alternatives to gasoline on the road today. In fact, we're a leader in the production of alternative fuel vehicles (AFVs) with more different types of AFVs on the road than any other automaker. Together, these five fuels offer the potential for reduced tailpipe emissions and increased energy security.
This Ford electric Ecostar, currently being tested by the Hampshire Constabulary, is the first advanced electric police vehicle in the United Kingdom. This electric vehicle is part of the largest electric test fleet in the world. By the end of 1995, Ford will be testing a total of 103 Ecostars worldwide --81 for testing in independent fleets in the U.S., Canada, Mexico and Europe, and 22 for evaluation and development work by Ford.
Our Cars Are Running On Rubbish: Ford has vehicles in Switzerland that are part of an experimental test fleet powered by biogas --methane gas that is commercially produced by biologically decomposing organic waste.
The "bi-fuel" F-Series pickup shown in the picture, runs on either natural gas or unleaded gasoline by using two separate fuel systems. It is being sold in select North American markets through an innovative conversion program with qualified modifier companies. When operated on natural gas, a vehicle's smog-forming potential can be reduced by up to 60 percent.
The 1996 Ford Crown Victoria full-size sedan pictured is the first mass-produced, dedicated natural gas-powered, passenger car manufactured by an automaker.
For those who can’t obtain or afford any of the alternative fuel vehicles on the previous page, you may want to take note of the tips below to get the most mileage out of your conventionally fuelled vehicle.
How to Drive Green:
Maintain a proper engine tune-up to keep your car running efficiently. Keep the wheels aligned. Wheels that are fighting each other waste fuel. Underinflated tires increase rolling resistance and reduce fuel economy. Also, underinflated tires wear rapidly. Check the vehicle's door-post sticker for minimum cold tire inflation pressure
Use good quality, energy-conserving (EC) oils, with viscosity grade consistent with your owner's manual. Use a fuel with good detergent additives --to keep the vehicle engine clean and, therefore, performing efficiently. Use a high quality fuel with an octane rating appropriate for your vehicle and use the lowest octane possible. Check the owner's manual for the manufacturer's recommendation.
Avoid piling a lot of luggage on the roof rack. The added frontal area reduces aerodynamics and will hurt fuel economy. Start the car and immediately, but gently, drive away. Don't leave your car idling. Start slowly, avoiding rapid acceleration. Aim to maintain a constant speed. Every time you pump the accelerator you're pumping more fuel into the engine. Drive at posted speed limits --that's a tip that may save a life as well as fuel. Don't drive with your windows wide open. That increases aerodynamic drag on the highway and lowers fuel economy.
Minimize the use of the air conditioning system. Rather than run it continuously, use the vent setting as much as possible. When you get to your destination, park --in the shade-- to reduce the need for using the air conditioner.
FROM THE PAST
Go one step further than the above article to save fuel, electrify your bike!!!! Another idea and commercial venture from 1935. From the advertisement, it obviously works better around Christmas! However, all jokes aside, there is probably some merit in this modification even today.
SPORTY ELECTRIC VEHICLE
American company, AC Propulsion, has developed a prototype electric vehicle designed by Alan Cocconi and is called the Zero. The car was originally designed to be fitted with a Suzuki motorcycle engine, but has been redesigned to accept a 220 horsepower, air cooled, AC induction motor. This motor generates 180 foot-pounds of torque from zero RPM! Top speed has been governed to 87 MPH while the zero to 60 MPH time is 4.9 seconds. Range is 60 to 100 miles when driven on the highway. The strategic placement of batteries in the Zero, twelve within each door and four across the rear of the cabin, eliminates the need for a bulky battery box in the cockpit or the boot. It also helps the car achieve a front to rear weight distribution of 47/53 percent. The 1,210 pounds of Optima lead-acid batteries account for slightly more than half of the fibreglass car’s weight.
The Zero has regenerative braking, which feeds electricity back to the batteries by changing the drive motor into a generator during coasting. Cocconi hopes to attract enough investment to allow production of the car as a $60,000 to $100,000 exotic with a manufacturing volume of a mere 10 to 100 per year.
ACTION POTENTIAL STIMULATION THERAPY
South African, Gervan Lubbe, has developed a device which is claimed to give relief from arthritis, osteoporosis, as well as several other chronic and acutely painful conditions. Gervan began his research after he read an article on how nerve impulses stimulate neurons which are vital to normal motor responses. Due to waste products, the body’s natural impulses weaken. If the impulses were imitated and applied to the right spot, the author concluded, many pains associated with old age would disappear. The result of this research is Action Potential Stimulation Therapy (APS).
The light electric current of the APS imitates the human body’s natural nerve impulses. The impulses are applied directly to the skin on the affected parts of the body. A light prickling is the only sensation. The device improves blood circulation, relaxes the lymphatic vessels and improves lymphatic circulation. Apparently it breaks down biochemical and metabolic waste products, uric acid, inflammation and edema.
The standard treatment takes only eight minutes and the device costs R4 500. (Whatever that is in A$) At present Gervan’s company, Tech Pulse, produces 500 units per month, however since the American FDA has since approved the device for sale in the United States, sales are expected to grow to 100,000 units per month. The original article that this information came from appeared in the F&T Weekly, 11th April, 1997.
SPACE POWER DEMONSTRATOR ENGINE
Large Free-Piston Stirling Engines: The first generation of hardware in this program, shown here, was the Space Power Demonstrator Engine (SPDE). The SPDE was a free-piston Stirling engine coupled to a linear alternator. It was a double cylinder, opposed-piston converter designed to produce 25 kWe at 25% overall efficiency. After demonstration, the SPDE was modified to form two separate, single cylinder power converters called the Space Power Research Engines (SPRE).
The SPRE has a design operating point of 15.0 MPa using helium as the working fluid. The 650 K hot-end temperature and 325 K cold-end temperature provide an overall temperature ratio of 2. Piston stroke is 20 mm and operating frequency is about 100 Hz. The SPRE incorporates gas springs, hydrostatic gas bearings, centering ports, and close clearance non-contacting seals. SPRE tests results are discussed in the references, Spelter et al. 1989, Rauch et al. 1990, Cairelli et al. 1991, and Wong et al. 1992. (See references below)
The second generation of hardware, the Component Test Power Converter (CTPC), was to be a 25 kWe modular design consisting of two 12.5 kWe/cylinder opposed piston converters. Only one-half of the CTPC was fabricated and tested. Details of the design, fabrication and early testing are reported in Dochat and Dhar 1991, and Dochat 1992. During the first-fully functional test of the CTPC, the design goals of 12.5 kWe output power and 20% overall efficiency were easily surpassed.
The mean helium working gas pressure of the CTPC is 15.0 MPa, heater temperature is 1050 K and cooler temperature is 525 K. The pistons oscillate at 70 Hz. The novel "Starfish" heat-pipe heater head design greatly reduced the number of braze joints, relative to the SPDE tubular heater design.
Mechanical Technology, Inc. of Albany, New York designed and built both the SPDE and the CTPC, under NASA contracts. For those who are looking for more information on “Large Free-Piston Stirling Engines”, the following references may be helpful.

The next meeting will again be on the second Friday of the month, this time being FRIDAY 10TH OCTOBER . The doors will open at 7.30pm, while the meeting will start at 8pm.
This month’s guest speaker is REBECA HALL from Sound Signatures who will be talking on:
BIO-ACOUSTICS AND HEALING
Bio-Acoustics is the study of frequencies thought to emanate from all living systems. The voice is seen as a hologram of the body and an assessment of the normal speaking voice can be used to determine the balance of physical and mental activities, chemical and nutrient levels and muscular weakness to name a few. So come along to the meeting to find out more!! (Don’t forget your $3 admission and something to share for supper.)
PHRENETIC PHRASES ANSWER: Stomach cramp.
