April 2004 Newsletter
March Technical Group Meeting
The March Technical Group meeting began at 8.05PM with 28 people eventually attending. Proceedings were opened by Robert who welcomed all those present and notified us that the April meeting will be shifted to the 16th because of the clash with Easter.
Ray had the first demonstration with components of his electric car conversion. He is converting a KC Laser to electric operation using two Crown forklift motors. At this stage Ray has only fitted one motor to the transaxle which he ran at the meeting on 24V to show it working. The motors are designed for 48V but are eventually going to have 110V applied to them to reduce electrical losses and obtain more power output. The motors will run at greater than 3000 rpm through the 5 speed gearbox fed from batteries mounted under the bonnet and in the space where the rear seat used to be. Projected cost for this project is $6-7000 with the main criteria for registration being that the total weight is the same as the original vehicle, which should not be a problem once the original engine, fuel tank, exhaust system, radiator, rear seat, etc have been removed.
I brought along the lawn mower that I have converted to electric operation using a modified Lucas starter motor. A switch on the handle operates a starter solenoid which switches the large current needed to drive the motor. A 12V 40AH battery supplies the power to run the mower which more than lasts the 20 minutes required to cut my lawn. The battery is recharged with a 64W solar panel and takes about 8-10 hours.
Ken explained the operation of a high current switching circuit that he has designed. It was designed as a driver circuit for an experimental motor and the input is via a photocoupler to give isolation. The circuit needs no snubber circuits or zener diodes to control spikes and uses 5 by 50 Amp FETs to switch the large current. The conversation then changed to valveless pulsejet engines. Ken explained how these are a tuned resonant device with no moving parts, have a good power to weight ratio and make lots of noise.
Lionel demonstrated a brilliant little vacuum pump that he has designed and built. The pump sits in a bath of hydraulic oil and is operated by turning a handle with only a few turns making the vacuum gauge go off the clock. Lionel explained some of the problems he encountered building the pump and how he overcame them. He then connected the pump up to a sealed jar of water and made it "boil" by reducing the vacuum on it. Lionel originally designed the pump to enable him to efficiently refill printer cartridges although he has found that the vacuum has to be kept down to less than 25" to prevent damage to the cartridge.
Michael brought along his hydrogen/Joe cell experimental setup again, this time having modified the cell by replacing the centre tube with nylon rod and the plastic spacers with teflon. He also explained the different electrode connections that he has tried and mentioned that he has tried a vacuum on the cell. Michael then gave a demonstration of the cell running from a 12 volt battery with some bubble lighting and loud bangs. Finally he talked about how he intends building a stainless steel version next with a small motor in the bottom to spin the water in the cell followed by a full on cell using Schauberger principles using egg shapes and a twister pipe.
Andrew donated a video on the Split Cycle engine (What did happen to that???) to the library and talked about one of the things he is working on which is generating steam and passing it through a catalyst to generate hydrogen for assisting running a car engine. He also mentioned that Ecovortec have 20 units going to France for use as mixer units for dissolving chemicals in water. Matthew mentioned new government regulations regarding connecting things to the water supply.
Ron, always one to find the latest electronic gadgetry, demonstrated a "128M memory stick" which plugs into the USB port on a computer for downloading of programmes, can play MP3 files and can also be used as recorder for 16 hours of bad quality recording or 3 hours of good quality. Ron had his unit strapped to some headphones and passed them around for people to listen to during the meeting. At the time of the meeting Strathfields had these "sticks" available for $170. Ron said that he has finished converting the group's 92 audio tapes onto 3 CDs which has been a mammoth effort on Rons part and is much appreciated by the ASTRO group - thank you Ron. Finally he showed a bottle that he has drilled a hole in the side of so that it in effect it becomes a glass with a long neck which enables it to be used without dust etc falling into it while it is sitting around on the bench.
Jan was the last presenter for the night with a lever system that he claimed showed overunity. George assisted in the demonstration but the general consensus seemed to be that the extra length of one of the levers was providing the extra weight that was giving the effect. Jan had received an email during the past month from someone claiming they have built an overbalancing wheel that is producing power.
Some chit chat followed which included real estate agents using energy clearing of houses remotely, a scientific study of crop circles by BLT Research and Matthew asking the question why do vacuum cleaner hoses have the overlapping of joins facing the wrong way so that things get caught and clog the hose?
The meeting officially closed at 10.40PM followed by supper

The Techno Maestro's Amazing Machine
A maverick inventor's breakthrough electric motor uses
permanent magnets to make power and has investors salivating
When we first got the call from an excited colleague that he'd just seen the most amazing invention a magnetic motor that consumed almost no electricity we were so skeptical that we declined an invitation to go see it. If the technology was so good, we thought, how come they didn't have any customers yet? We forgot about the invitation and the company until several months later, when our friend called again. "OK," he said. "They've just sold 40,000 units to a major convenience store chain. Now will you see it?" In Japan, no one pays for 40,000 convenience store cooling fans without being reasonably sure that they are going to work.
Seeing is believing
Nobue then takes us through the functions and operations of each of the machines, starting off with a simple explanation of the laws of magnetism and repulsion. She demonstrates the "Minato Wheel" by kicking a magnet-lined rotor into action with a magnetic wand.
Looking carefully at the rotor, we see that it has over 16 magnets embedded on a slant apparently to make Minato's machines work, the positioning and angle of the magnets is critical. After she kicks the wheel into life, it keeps spinning, proving at least that the design doesn't suffer from magnetic lockup.
She then moves us to the next device, a weighty machine connected to a tiny battery. Apparently the load on the machine is a 35kg rotor, which could easily be used in a washing machine. After she flicks the switch, the huge rotor spins at over 1,500 rpms effortlessly and silently. Meters show the power in and power out. Suddenly, a power source of 16 watt or so is driving a device that should be drawing at least 200 to 300 watts.
Nobue explains to us that this and all the other devices only use electrical power for the two electromagnetic stators at either side of each rotor, which are used to kick the rotor past its lockup point then on to the next arc of magnets. Apparently the angle and spacing of the magnets is such that once the rotor is moving, repulsion between the stators and the rotor poles keeps the rotor moving smoothly in a counterclockwise direction. Either way, it's impressive.
Next we move to a unit with its motor connected to a generator. What we see is striking. The meters showed an input to the stator electromagnets of approximately 1.8 volts and 150mA input, and from the generator, 9.144 volts and 192mA output. 1.8 x 0.15 x 2 = 540mW input and 9.144 x 0.192 = 1.755W out. But according to the laws of physics, you can't get more out of a device than you put into it. We mention this to Kohei Minato while looking under the workbench to make sure there aren't any hidden wires. Minato assures us that he hasn't transcended the laws of physics. The force supplying the unexplained extra power out is generated by the magnetic strength of the permanent magnets embedded in the rotor. "I'm simply harnessing one of the four fundamental forces of nature," he says. Although we learned in school that magnets were always bipolar and so magnetically induced motion would always end in a locked state of equilibrium, Minato explains that he has fine-tuned the positioning of the magnets and the timing of pulses to the stators to the point where the repulsion between the rotor and the stator (the fixed outer magnetic ring) is transitory. This creates further motion rather than a lockup.

Peter's Page 13th February 2004
Ken ... Opened the meeting at 8.00pm. He started off with an internet article, http://www.lifeaftertheoilcrash.net ,which suggests that the world oil production peaked in the year 2000 and that the world is rapidly heading for a crisis, as one of the main by products is ammonia, which in turn is a main ingredient of agricultural fertiliser. A grim future picture was spelt out.
Peter ... has better news for the future with a brief report on "A New Technique for Continuous Operation of Nuclear Fusion Reactor". He said that we in Australia had to get over our baseless nuclear phobia and try to get on line with a new fusion reactor technology that offered an abundant source of cheap safe electricity. France and Japan were the finalists in an international bid (EU, USA, Russia, S Korea, China and Japan) to site the "International Thermonuclear Experimental Reactor". Peter said that fusion power produces no greenhouse gasses and only very low levels of radioactive waste. It would run on an isotope of hydrogen, extracted from water. Fusion reactors do not consume uranium or plutonium - the fuel of conventional fission reactors - and do not use an atomic chain reaction. More information can be accessed from a Google search on " Japan Atomic
Energy Research Institute, JT60(JAERI Tokamak - 60).
Devashoen ... spoke briefly on vortex devices such as vortex chimneys and vortex launchers. He said that toy vortex launchers were available via the internet. He had also been given information on orgone energy from Mathew Winguard and Dan Winters. He invited interested members to contact him for more information.
Andrew ... reported that he had had positive feedback from people using his Ecovortec water conditioner.
Peter ... read an article from "Infinite Energy - Water" magazine about "Electrolysed Water". Briefly, the Russians developed a technique for electrically charging water about 40 years ago. About 5 grams of sodium chloride per litre and 400 volts DC will very inexpensively produce a non toxic disinfectant that will kill all bacteria (including anthrax) in seconds. They squirt it directly into surgery incisions to eliminate infections as well as washing down surgeries and wards to keep them sterile. He said that if this was used by our chicken, pig, dairy, orchard (etc) farmers there would be very little disease in their products, at minimum expense and no toxicity.
Dino ... backed up what Peter had said and added that the Koreans and Japanese had been producing and using water electrolyzers for many years. They use them to make oxygen rich (acidic) water for cleansing and healing their skin and hydrogen rich (alkaline) water for drinking (to alkalize their bodies and cleanse their blood). See the following Webb site for extensive information on this issue. http://www.bionatural.com.au Dino drew up and explained how these units worked and explained how the REDOX measurements of acid and alkaline water worked and affected our bodies.
Ken ... put the motion that Andrew S subscribe (for ASTRO) to "Infinite Energy" magazine, pre read it and report any interesting articles to the meetings. The motion was carried.
Robert ... spoke on enzymes and the necessity to our body for digestion and correct and efficient functioning of our immune systems. For indigestion we should probably take an enzyme supplement rather than an antacid (which mess up the acid balance and further disrupts digestion). He also mentioned that there were three types of wormwood (an herb). A type called autemesia, found in China, will have a positive affect on malaria. Malaria causes the Iron component of the blood to clump up and this wormwood causes its reversal. He also added that in tests on dogs with cancer, a 100% reversal was achieved.
Robert then introduced the Guest Speaker ... Martin Lewiki, a talented Astronomer, Guitarist and Singer. Martin's topic was
"The latest discoveries in Sky and Light Pollution".
Martin ... gave an excellent talk on a subject that most of us had considered very little. He used coloured slides and statistics to show us that poorly designed street lights, advertising illumination (eg. car yards) and domestic lighting has many adverse effects on humans, wild life, social behaviour and wastes up to 30% of the electricity it uses. There is an internet site, by Dr Barry Clarke, detailing the association of lighting and crime. See ... http://www.asv.org.au. The Czech Republic had brought in light pollution laws, Lombardy Law (UNESCO) in Italy had declared the night sky as a heritage and 34 cities around the world have followed suit. Arizona (USA) has had light pollution laws since 1958. Editor's note; since this talk the street lighting supply authority (ETSA) of Adelaide, South Australia, has started replacing 60,000 street lights to rectify these very problems.
Robert thanked Martin and everyone for a good, informative and entertaining evening. The meeting closed at 11.15pm, followed by supper.
