Last Post

This will probably be my last post to this blog for the forseeable future.
Cross-section drawing of a disc-rotor UAER prototype (which has been built as a physical model)


I had intended to say quite a bit more on various topics; in particular the UAER (Unenergised Attraction - Energised Repulsion) idea I've mentioned before, and on mechanical perpetual motion in the Earth-based laboratory frame; but I've decided to take the late Paul Brown's advice, to "keep a low profile until you have completed your endeavour..."


Opposing genocide

The main reason that I've had to divert attention away from this blog is because I'm beginning communication with a group who have some interesting ideas on using technology to help oppose the ongoing worldwide agenda to exterminate the White race (the global "Coudenhove-Kalergi Plan" or "Genocide by Race Replacement" as it's sometimes called). While aware of this problem for some time, I had always thought, not least from their entrenched voting patterns, that almost all other Whites didn't care about it, and never would.

But maybe not — perhaps the reason has been general ignorance rather than indifference. Possibly the recent Brexit vote in the UK, and the political rise of Donald Trump and David Duke in the USA could be largely because of an (extremely belated) awareness and concern about this problem?

As this group says, the Internet was an example of White-invented technology that has significantly improved our chance of long-term survival, although it wasn't even specifically invented for that. There are other things, including technologies, that would make further improvements. They all need to be worked on — by whoever can do so, and not just by one, or a few groups.

The highest use for our inventive ability

White inventive ability being used specifically, at last, to aid the survival of Whites themselves ... whether anything will come of this of course remains to be seen — eventually.

At least this group has already shown how a long-known but, so far as I know, little-used communications method can be developed, which I find interesting in itself. Ironically, perhaps, they themselves have no internet presence, and are not interested in attempts at contact. ("We always find the ones we want.") Neither they nor I have a problem with me writing just as much as I have here.

Adieu for now

There is a small chance that I may be back in future, with fuller and more explicit comments than in this post. But for now, I say "Adieu."

The Kawai Magnet Motor

Two years ago, on 19 and 24 June 2014, I made two "out of sequence" posts on the motor invented by Teruhiko Kawai of Japan Science Research Laboratory.

Because this would now be the proper time for them to appear, and also because I now have too many other external issues requiring my attention to do anything else, I re-post them, slightly edited, below.

[Part I]

Disinformation — "Coloring with Looney Tunes"

In her pioneering book The Coming Energy Revolution — the Search for Free Energy author Jeane Manning quotes (on p160) a scientist "with contacts in international circles" as saying:—

"...if you give the public disinformation, people become confused and passive. . . . It becomes a kind of cognitive dissonance; people tune out.
    Obviously, when you're dealing with a sensitive area, the government will protect its interests. We would be naive [to think there are not agencies doing this]. The only way to make legitimate information inert, less viable, is to embellish it. . . color it with all kinds of Looney Tunes. . . . Give contradictory information. So no matter how much the public might be interested in the topic, it creates enough confusion that people tend to get passive."

It is simply a fact nowadays that there are hundreds, if not thousands of internet videos and other reports on "magnet motors" and other devices all claiming to be true free energy or perpetual motion machines. In other words there is now such a large amount of "noise" or "Looney Tunes" smothering this topic that any genuine device has hardly any chance of being recognised. 

Of course I realise that, whatever may have happened in earlier years, the large majority of these devices are now being made and publicised by people just "having fun", or making "practical jokes" etc. No doubt there is also a small minority who really believe, rightly or wrongly, that their inventions are genuine.

I'm not complaining about this state of affairs; just noting the fact.

An invention from before the age of "Looney Tunes"

However, what would have happened if, more than two decades ago, in a modern, developed, "high-tech" nation (Japan) an inventor had built a successful "over-unity" magnet motor? And what if his unequivocal claims of properly measured over-unity performance were broadcast in a television program to the general Japanese public? What if that program also showed his claims being publicly endorsed by Engineering Professors at two well-respected universities (Waseda and Meiji) as well as a high-ranking industry representative (a Sumitomo Aerospace Division Chief)? What if the program specifically urged private enterprise to develop the invention?

Well, all of that did happen. The short answer to what happened next is: "nothing, overtly". The best that can be said is that more data was gained on how difficult it will be to achieve the New Energy Age (and consequently how disruptive it will be when it is achieved).

The "Dream Energy" television program

I recently managed to obtain a copy of that Japanese television program. It is the so-called "Dream Energy" program, broadcast by the Fuji Television Network on 20 October 1993. A recording of it was later incorporated into Tape 4 of the Cold Fusion Day at MIT videotapes, from where I believe my copy originated. 

Reference: Cold Fusion Day at MIT set of videotapes, produced by Cold Fusion Technology, P.O.Box 2816, Concord, NH 03302-2816, USA.

These videotapes used to be available from Infinite Energy magazine, at the same address given above, but as far as I can find out, that is no longer the case. The only reference I can now find to this event is at, page 21 of 57, section titled:—

COLD FUSION, A Massachusetts Institute of Technology IAP Program — Video-Lecture-Demonstration Program, January 21, 1995, Saturday 9AM - 5PM, Room 6-120, Physics Lecture Hall, First floor, main building of MIT.

In the box on the right of the page, the 15th item is titled "Video Tape from Japan, Fuji Television (8 minutes) — 'Magnetic Energy'".

A screenshot from the Fuji Television program, introducing "Dream Energy"

Now posted

The "Dream Energy" program is an important piece of historical evidence for anyone interested in Free Energy/Perpetual Motion. I have never been able to find it anywhere on the Internet, so I've posted it myself.

Here is the video, which I also posted to YouTube on June 4, 2014, at :—


The video is introduced and given English-language narration by Dr Eugene Mallove (1947 - 2004), founder and former Editor-in-Chief of Infinite Energy magazine. The other individual seen during the introduction is Bertil Werjefelt of PolyTech(USA).

The end of the program, discussing the retrofitting of existing electric motors, is somewhat anticlimactic. However, the program states twice that the motor shown earlier, i.e. the Kawai motor, delivers more energy than it consumes.

On July 25 1995 the Kawai motor was granted US Patent 5,436,518. A motor efficiency of 318% can be calculated from the self-consistent experimental data given in that patent. (See the paragraph in the Description starting with "Pure steel was used as a magnetic material.")

[Part II]

Infinite Energy magazine, Vol 1, No 1, March-April 1995

In the "Dream Energy" video I posted [above], Dr Mallove's narration is from the translation published in the very first issue of Infinite Energy, p48. This translation was originally provided by Prof. James Kenney of the Department of Japanese Studies at the University of Hawaii. 

This issue is not available as one of the back issues still being offered for sale by Infinite Energy. To place it on record, I've reproduced the translation below:—

“The Dream Energy”

Newscaster Woman’s Voice:
It’s been said that it’s impossible to gain usable energy from permanent magnets.

Newscaster Man’s Voice:
But it’s been discovered that it’s indeed possible to extract energy from permanent magnets; and our staff has pursued this matter to reveal to you the secrets of this new technology.

Script on Screen:
[Professor at Waseda University, Engineering Department (Physics) Prof. Yoshihiko Otsuki]

This is something that can turn the whole 21st century around — in terms of new energy. When I visited and saw the experiments in action my hands literally trembled from excitement.

Script on Screen:
[(Japan Science Research Laboratory) = Nihon Riken. Mr. Teruhiko Kawai]

Narrator Woman’s Voice:
What had surprised Prof. Otsuki was the fact that there was a high energy ratio achieved; that there was, in fact, a ratio of over 100%. [The phrase used is “more output than input.”]

Script on Screen:
[Meiji University Scientific Engineering Department (Engineer) Prof. Masao Mukaidono]

What we found were some very interesting facts.

Narrator Woman’s Voice:
Permanent magnets have the nature to repel and attract. Prof. Kawai has succeeded in making permanent magnets produce mechanical energy. To convert magnetic energy to mechanical energy.

Script on Screen:
[Now Revealed: Dream Energy]

Narrator Woman’s Voice, and Script on Screen:
[Tokyo, Kamata]

All he ever thought about was permanent magnets. And one day, he discovered the principle that magnetic energy can be converted to mechanical energy.

Script on Screen:
[Experimental Equipment]

Narrator Woman’s Voice:
Was this really possible? The first experiment was about to begin.

Script on Screen:
[Prof. Kawai]

I was very anxious ... Was it really possible? Will I be able to obtain usable mechanical energy?

Script on Screen:
[Jan 12, 1991 — this fact was determined]

Man’s Voice:
We placed the permanent magnet — more rotational speed was observed as well as torque.

Narrator Woman’s Voice:
Yes, it was indeed possible to obtain more mechanical energy.

I was extremely happy with the results.

Narrator Woman’s Voice:
Let’s have Prof. Mukaidono, who has been with this experiment from the beginning, comment on it.

What we have here is the more effective employment of switching — of turning on and off magnets in a sequence.

Script on Screen:
[The Principle of Switching]

Same poles attract, only the opposite poles repel. [Note that this apparently wrong statement is correct in terms of what is being shown on screen.] Here, we have two magnets with a piece of iron between them. Then, this piece too becomes magnetised and can attract another piece of iron. Switch the pole on one magnet, and this piece drops.

Script on Screen:
[October 12, 1993 — This principle is made public}

Man’s Voice:
Let me explain using a diagram. Here we have a motor with a permanent magnet imbedded, with protruding magnets placed around its frame. With the core magnet, those individual magnets are magnified and through switching these individual magnets, the motor turns.

Narrator Woman’s Voice:
With sequential switching of the external magnets, the motor turns and increases its speed. This principle can be applied to both direct and alternating current motors.

Script on Screen:
[Staff Member: Isamu Fukui]

Narrator Woman’s Voice:
We place a very powerful permanent magnet into the rotor. This is a direct current motor employing the permanent magnet principle.

Script on Screen:
[Direct current motor]

Narrator Woman’s Voice:
What we had here was an output exceeding 100%. Seeing the results, the professors were amazed.

Where did this extra output come from? This is really a revolutionary find!

This can only be attributed to an extremely higher level (magnitude) of electron levels.

Narrator Woman’s Voice:
Now we begin an examination of this extraordinary motor. In February the engineers of the Sumitomo group examined the motor.

The rotational speed is very high ...

Narrator Woman’s Voice:
They check to see that all data achieved are correct.

We checked to see that the same readings were gained on other meters; not just the ones we used in our initial experiments.

Narrator Woman’s Voice:
Prof. Kawai feels that they have laid the foundations of the principle; now, it’s time for private enterprises to utilise these findings.

Script on Screen:
[Narration = Miki Aoki]

Narrator Woman’s Voice:
Now, they will apply the principle to existing motors (that are out on the market).

Script on Screen:
[Experimenting with store-bought motors]

Narrator Woman’s Voice:
The turning ability of the motor is increased and efficiency is also greatly increased; 92 - 98% is achieved.

Script on Screen:
[Sumitomo Aerospace Unit 2, Division Chief Hiroshi Tamagawa]

What we have here is a curious phenomenon whereby we’ve come up with a better motor.

Narrator Woman’s Voice:
Prof. Mukaidono has come to check the meter reading and data.

We’re seeing what levels can be achieved with existing motors using our principle. We’re now showing 0.66 amps. Rotational speed is 1500 RPM and shows no change.

Script on Screen:
[Prof. Mukaidono]

Same amps and same voltage ... seeing this, what we have here is a motor that we’ve never seen before. With better output, we’ll have a better, more efficient motor. If motor builders take a look at this, they’ll be just amazed!

Narrator Woman’s Voice:
Prof. Otsuki has also arrived to take a careful look.

Script on Screen:
[Prof. Otsuki]

I sure am surprised. The utility rate is up by 15 - 20%. Using conventional oil-based energy, the best one can expect is an energy savings of 5%. This is dramatic energy savings — perfect.

Script on Screen:
[Magnet-Powered Car]

Narrator Woman’s Voice:
The principle can be applied to running cars, trains, and also the running of household appliances. The energy is highly efficient, economical, and very clean.

Script on Screen:
[Prof. Kawai]

We’ve discovered that these secrets were present in our surroundings (Nature) all along ... we can now use them to help restore the environment that man has been abusing.

Newscaster Man’s Voice:
This is good, clean energy ... amazing!

Newscaster Woman’s Voice:
And, there’s no waste materials produced ... truly the source for cleaner, more efficient energy for the future.

Screen shot of test data

Data from brake tests, showing motor efficiency ( 効率 ) of  123.7% (in the close-up shot) to 164.0%.
This had apparently improved to 318% by the time Kawai's US Patent 5,436,518 was granted.

The EPRI Magnet Motor

Cross-section of the EPRI magnet motor, from US Patent 5,304,882.
Note the flat permanent magnets under the rotor pole-pairs, and the stator of typical
switched reluctance design, similar to the Takahashi Self-Generating Motor.

Permanent magnets in a switched reluctance motor

An early "significant patent" [Ref 1] for a switched reluctance motor with permanent magnets is US Patent 5,304,882 of 19 April 1994, issued to Thomas Lipo and Yuefeng Liao of the prestigious Electric Power Research Institute (EPRI). According to the Wikipedia entry on EPRI, "The institute's research and development program spans every aspect of generation, environmental protection, power delivery, retail use, and power markets. EPRI provides services to more than 1000 energy-related organizations in 40 countries. It has more than 900 patents to its credit."

Was it ever built?

While this patent 5,304,882 claims many very important improvements over previous designs, (including "higher efficiency") I can find no evidence that the patented machine (shown above) was ever actually built — it seems to have been entirely a series of computer simulations. 

Free energy is implied

The most provocative claim was that the invention could produce between √2 and 2√2 times as much torque as a comparably-sized conventional machine having the same winding heat dissipation and degree of magnetic saturation. Since energy output is directly proportional to torque, through a given angle of rotation, this implies an energy output of more than 1.4 to 2.8 times that of the conventional machine for the same current (and hence presumably for the same energy input). Since a conventional switched reluctance motor can achieve 94% efficiency, this claim, supported by figures from the patent shown below, implies that this EPRI motor could quite easily deliver free energy, although nothing explicit was said about that.

Figures from US Patent 5,304,882, showing energy conversion loops of magnetic flux linkage (here labelled λ, but more usually ψ) vs stator coil current.

Note especially the parallelogram-shaped energy loops of Figures 8A and 8B, showing operation in the second
quadrant as well as the first, giving a much larger total energy output than could be achieved with an equivalent
conventional switched reluctance motor (represented by the smaller cross-hatched loops). 

Notable points

The following points about the EPRI motor are worth noting:

-  Although the patent is titled "Variable reluctance motors with permanent magnet excitation," the authors state that "...The essential feature is that the permanent magnets see a constant reluctance flux path at all times, that is, the total overlapping stator/rotor pole areas must remain constant." (My emphasis).

-  Figures 8A and 8B above strongly suggest that the motor is able to use current reversal to achieve magnetic repulsion as well as attraction.

-  Considering all of the major improvements claimed for their patented motor, it is surprising that EPRI apparently did not build any version of it as a physical prototype — at least no such prototype has been publicised, to my knowledge. It is also surprising that more than twenty years later, manufacturers still seem uninterested in incorporating permanent magnets into their commercially available switched reluctance motors in this way, in order to achieve anything like the energy conversion loops shown above.

Are these energy conversion loops too obvious?

In two subsequent patents, also on variable reluctance machines incorporating permanent magnets, US Patent 5,672,925, and WO9418855, the same EPRI inventors did not provide any energy conversion loops, whereas by analogy with US Patent 5,304,882 they would have been expected.

On espacenet, I found one more associated patent from these inventors, US Patent 5,825,112. This patent does have the provocative large "two quadrant" energy conversion loops similar to those shown above, and again claims to produce torque of between √2 and 2√2 times that of a conventional motor. 

Curiously, I found on espacenet that I could easily see the mosaics (patent images) from the two patents that did not have any energy conversion loops, whereas I could not see the mosaics from those (US Patents 5,304,882 and 5,825,112) that did have them.

I've mentioned before that although espacenet remains my favourite site for patent searches, I do occasionally have a few problems with it, so I don't really think this is an attempt at suppression! (If it is, it's a very feeble one — the patent images are easily downloadable and visible in all cases from the "original document" tab on their patent webpages).


As usual, there are plenty of unanswered questions concerning this EPRI work, in particular the motor of US Patent 5,304,882. I'll confine myself to just a few important ones:—

(for EPRI):—

-  Was a physical prototype ever built? If not, why not, in view of all the claimed advantages? If it was, what were its test results?

-  Can any interpretation be put on the large parallelogram-shaped energy loops of Figures 8A and 8B, other than that they show over-unity energy output? If so, what?

-  Why were energy loops omitted for US Patent 5,672,925, and WO9418855?

(for switched-reluctance motor manufacturers):—

- Why are you apparently not interested in incorporating permanent magnets into your motors and controlling them in the way shown in this EPRI work, so that their energy loops can extend into the second as well as the first quadrant, to achieve the far better performance claimed by EPRI (and also by Yasunori Takahashi, with his "self-generating" motor of very similar design, which he explicitly claimed to be a free energy motor)?

Stability of Permanent Magnets

Claims that magnets deliver energy by losing their strength

In the past, several magnet motor inventors have claimed that the permanent magnets in their machines deliver energy into those machines by losing their strength over time, i.e. that the magnets themselves are not stable, and so are a source of energy from that loss of strength. David Porter makes this claim at 1:04:20 in the video cited previously, at 

Yasunori Takahashi made a similar claim, to Chris Tinsley, about his Self-Generating Motor:—

"I asked Mr. Takahashi about this scooter. Was it over-unity? Seemingly not. Apparently the magnets lose strength at about 3% per year, and Takahashi claims this to be the source of the energy. But he had a glint in his eye when he said it. When I said, "No, it isn't," he grinned."

Ref: "Chris Tinsley: Travels in the New Energy Age," Infinite Energy magazine Vol 1, No 5/6, 1996, p29.

Such claims imply that permanent magnets are "used up" as if they were, say, "a gallon of petrol or a torch battery" (we'll meet that expression again, below).

Ridiculous — in theory and practise

This is a ridiculous concept, both theoretically and practically, as will now be shown. Why some inventors have made such claims, which they must know will reduce their credibility, is yet another of the many unanswered questions that swirl around the subject of over-unity magnet motors.

Engineering Design Guide

There is some useful information on-line about magnet stability, e.g. at However, I couldn't find what I was really looking for — the Engineering Design Guide for permanent magnets which I first found in my local Public Library, of all places. It was eliminated from there many years ago (but not before I had copied most of it). I don't have any way of identifying it now apart from its first page, reproduced above.

Quoting from page 11 of this Engineering Design Guide:—

"Stability of permanent magnets

The designer planning to use permanent magnets must be confident that each magnet will remain stable in its working environment, or that any changes will be predictable. When a fully magnetized magnet is removed from the magnetizer, the first immediate loss of magnetization continues on a logarithmic scale, subsequent periods of 10, 10², 10³, etc, times the interval over which the initial loss was measured resulting in equal changes. If the first rapid change is accelerated by stabilization after magnetization, then — assuming a fixed steady temperature — the magnet is likely to remain stable to within 0.01 per cent for many years.

The chief causes of magnetic instabilty are temperature changes, exposure to stray magnetic fields, and mechanical shock or vibration, although in each case the same underlying mechanism is responsible. When a magnet is fully magnetized, it is thermodynamically unstable with the least stable domains trying to return to a state of lower energy by domain boundary movement or reversals. If the magnet is subjected to stray magnetic fields, or if thermal agitation is increased by a rise in temperature, then these unstable domains are the first to revert to their equilibrium state, leading to a loss of magnetization in the magnet. If, after fully magnetizing, some flux reduction is deliberately brought about by the application of a small alternating field, the unstable domains are the ones which are affected and, since these have already relaxed, a subsequent increase in temperature will have a reduced effect. It follows that stabilization by alternating flux reduction is a good general insurance against further loss, but for the highest stability requirements, this should be followed by cycling through a temperature range slightly wider than that to which the magnet will be exposed in use. Similarly the magnet may be subjected to any other abnormal conditions it is likely to encounter (for example, excessive vibration) in order to minimize further losses from these causes before it is put into operation."

So, as long as a magnet is first subjected to any conditions tending to demagnetize it which are slightly in excess of those which it will encounter in use, it will remain stable indefinitely.

(BH)max  or Energy Product calculation

Quoting again from the above Engineering Design Guide:—

"There is one particular working point on the demagnetization curve [of flux density B versus magnetizing force H] for which the product BH is a maximum. This maximum is referred to as (BH)max and is a useful characteristic of the material. It has the dimensions of energy per unit volume (Jm-3) and is sometimes called the energy product, although (BH)max is actually numerically twice the available energy of the magnet. For this reason the use of this term is not recommended, particularly as a magnet is not used as a source of energy in the same way as, say, a gallon of petrol or a torch battery."

The amount of permanent magnetic material used in David Porter's or Yasunori Takahashi's motors has not been reported, but we can certainly say that the permanent magnets in the Kure Tekko motor must have weighed less than its total reported weight of 155 pounds, i.e. 70.307kg. If we (generously) use that figure, and (very generously) assume all magnets to have been samarium-cobalt with a density of 8250kg/m³, that would give a volume of 0.008522m³ for its total magnetic material.

At say 20MgOe = 159155 J/m³ for samarium-cobalt, that means the total available energy from the energy product of the Kure Tekko motor's magnets would be very generously estimated at ½ × 0.008522 × 159155 = 678.16 joules.

We also have a reported power output for the Kure Tekko motor of 45 hp = 33556.5 watts. So if energy was really being taken from the magnets themselves to run it, then at full power it would have exhausted itself in about two-hundredths of a second!

The Takahashi "Self-Generating Motor"

Primary References:—

Infinite Energy magazine No 5-6, 1996, pp28-29, 35 and 36-37.

Japanese patent JPS2002291228 (A)

Fig 1  Sciex scooter with Takahashi Self Generating Motor

In 1994 in London, Yasunori Takahashi, Director of Research and Development at Sciex (UK) Ltd, demonstrated the first version of an electric motor scooter incorporating his permanent magnet Self Generating Motor (SGM). An article in the September 1994 issue of the British Broadcasting Company’s Top Gear magazine noted the impressive performance of the scooter. It was also demonstrated to a Senior Engineer at Nissan’s European Technical Center who remarked “If it checks out in our own tests, it has huge implications for everything which uses a motor — it could revolutionise the world.”

Chris Tinsley — investigation

In November 1995 Takahashi allowed Infinite Energy Contributing Editor, electrical engineer Chris Tinsley, an impromptu test ride of a later version of the scooter, shown in Figure 1 above.

Tinsley reported that after 25 minutes of riding under conditions which would have flattened much larger batteries (his intention was to flatten the batteries if possible) the small scooter batteries remained fully charged, as measured by his own voltmeter; the brakes were hot, and the motor was barely warm.  He was also shown a video of a Takahashi motor driving an alternator powering lamps estimated at about 120 watts, with no external energy input. Tinsley wrote an interesting report [Ref 1] and he managed to obtain some very provocative data from Takahashi’s company Sciex (UK) Ltd [Ref 2]. Some of the product literature claimed that at constant speed travelling the Self Generating Motor would deliver sufficient free energy not only to propel the scooter, but also to provide battery charging as necessary.

Magnetic Power Inc. — problems

In mid 1996 the Takahashi scooter was shipped to Magnetic Power Inc., in the USA. After problems with customs clearance, it was eventually tried out, and its batteries were quickly flattened.

About a year and a half after that, the following advertisement appeared in Infinite Energy magazine:—

“For sale. Sciex scooter with Takahashi motor. Used only for test purposes. It failed to confirm his claims.  Accelerates rather well (possibly due to ultracapacitors). Otherwise standard electric scooter from Taiwan. $2,000 invested. Make offer. Magnetic Power, Inc. 707-829-9391.” [Ref 3]


As usual, there are questions begging for answers. For example:

-  What was the outcome of the tests which Nissan planned to do?

-  Where are the scooters now? (i.e. the original, and the one tested in the UK and the USA).

-  Has the motor and controller of either scooter been studied in detail by an independent competent investigator? If so, what was found?

-  What was the official reason for the difficulties with clearing the scooter through US customs? (Bearing in mind that the delay could have allowed some technical dirty trick to have been played — for example substitution of the motor, and/or damage to the controller).

-  Why was the advertisement to sell the scooter placed in Infinite Energy magazine — a very unusual forum for vehicle sales? And why did it need to underline the failure of the scooter to confirm Takahashi’s claims? (Admirable honesty in advertising, but a cynic might be forgiven for thinking that the main purpose of the advertisement was to discredit Takahashi, rather than to sell the scooter).

-  What has happened to Takahashi today? He seems to be keeping an extremely low profile. And what were/are his comments on these developments? This touches on one more question which Infinite Energy themselves asked:— [Ref 4]

-  Why would someone of Takahashi’s background [Ref 5] get involved in something like this if it were fraudulent? What would be the point?

Chris Tinsley — dead

It is certain that Chris Tinsley would not have left questions like these unanswered. But he could not pursue them, because he died suddenly on October 1, 1997. (See

So we have been left, for many years, with a very unsatisfactory situation. The completely different performances of the scooter in the UK and the USA remain unexplained; the engineer best placed to look further into that died before he could do any further investigation, and the scooter motor's inventor has disappeared, at least from public view.

As seems de rigueur in such cases, claims have appeared for and against Takahashi, such as the usual unproven accusations of fraud, in the (surprisingly easily found) email exchange here.

This leads to a final question, which again I cannot answer — has any other credible investigator made any progress in following up on the Takahashi Self Generating Motor?
