Again we see that communication is difficult and memories are fallable.
Obviously I am remiss in not having sent this to you months ago as I intended
to, but as a sage of old observed "The spirit is willing, but the flesh is
During the first weekend of May, 1997, a group in Soeul, Korea headed up by
Mr. Chi San Park, held The First International New Energy Conference in
I attended this conference and gave a talk on various approcahes to free
energy. It was at this conference in Seoul, Korea that I saw the bicycle
wheel and had the opportunity to work with it unattended by anyone else.
The inventor is Kohei Minato, a Japanese rock musician, who reports that he
has spent a million dollars out of his own pocket developing magnetic motors,
because the world needs a better source of energy. He has several patents in
various countries. His latest patent that I am aware of is United States
Patent # 5,594,289.
His development efforts have gone in the general direction of the Adams motor
which the above patent is similar to. He had a working prototype of this
design at the conference and reported that it used 150 watts power input and
produced 450 watts output on a sustained basis.
About a year ago CNN (in the US) had a 10 minute segment about him and his
motors. In this video he is shown demonstrating two of his magnetic motors.
I have a copy of this film clip that he gave to me. I will make a copy and
send it to you. Unfortunately, the editors were not attuned to technical
details and the pictures of the running machines show little useful detail.
The Phillipine connection that you mention is completely erroneous. It was
The drawing on the web site is essentially correct with the following
exceptions. The counter weight is a single curved piece of aluminum covering
Each of the several individual magnets on the other half of the wheel are
slightly asymmetric, crescent shaped and nested. They are magnetised end to
end with the N poles out.
The motor is actuated by moving the N pole of a large permanet magnet (the
drive magnet) toward the wheel. As this magnet is moved toward the wheel,
the wheel starts to spin. As the magnet is moved closer to the wheel it
The acceleration of the wheel is rapid. So rapid in fact, as to be startling.
To put it another way I was very impressed. The motor works. And it works
In the film clip a slight pumping action of Minato's hand holding the magnet
is apparent. When I braced my hand so that there was no pumping action, the
motor still ran. In fact it seemed to run better. Pumping action by the hand
held magnet is not the power that drives the motor.
When the drive magnet is moved away from the wheel it coasts rather quickly
to a stop and comes to rest in a manner typical of any spinning bicycle wheel.
Again when the wheel is at rest and a large magnet is moved up to the wheel
it starts to spin. At no time is it necessary to touch the wheel to get it
Simply bring the N pole of a large magnet several inches from the wheel. The
particular orientation of the wheel when it is at rest seems to have no effect
on how well it starts to turn. Irrespective of how the wheel and the magnets
on it are sitting; move the drive magnet near, it starts to spin.
Move the magnet closer it spins faster. Move the magnet further away it slows
up. The wheel was mounted on a stand made of aluminum angle pieces bolted
together similar to the diagram in the above mentioned patent.
The axle of the wheel was mounted parellel to the surface of the planet. I
have attached a rough diagram of the wheel.
Apparently the geometry of the magnets on the wheel is very important and
subtle. I have built several small models none of which have shown the free
energy effects of Minato's machine.
The conference in Seoul was attended by several hundred people, most appeared
to be under 40 and evenly divided between men and women. Presenters were from
Korea, US, Japan, and China. Simultaneous translation was provided for all
talks in the 3 day conference.
Jerry, I hope this information is useful. I may be contacted by e-mail at
