The Energy Revolution
  1. Cosmic Energy includes Energy from Air, Water,
    Gravity, Magnetic, Electromagnetic, Ions in the
    Air, etc
  2. These Energies are virtually infinite.
  3. They are non-polluting, no transportation cost
    and inexpensive.
  4. They obey the Law of Conservation of Energy.
  5. Some can even produce Global Cooling.
  6. Many inventors produced machines which they could
    not explain (some wrongly thought that they
    created the Perpetual Motion Machines that do not
    need energy!)?

Revolutionary Impact
  • Scientific
  • Scientists will enter the post nuclei era
  • Financial
  • Worth more than all wealth in the Fissile Fuel
    Era
  • Patent Royalty income gt HK20,000 billion (2.5m
    per Hong Kong Citizen!)?
  • Social
  • Modern Wealth Meaningful Economic Activities
  • Such Wealth can be Infinite Poverty will be
    History
  • Military
  • Doomsday Bomb effectively forces balance of power
  • Personal (fame, fortune, temptations)?

Statement from Inventor
  • One of the Inventors (Lawrence C.N. Tseung)?
  • Believes immense wealth will be created
  • Donates 90 of his income to Educational Causes
  • The present task is to
  • Create opportunities for others to shine
  • Let China and its people have first priority
  • Strongly believe that we should promote World
    Peace NOW
  • Scientists are on the way to master total
    mass-energy interchange (Possibility of Doomsday
    Bomb)?

Government Involvement
  • From our painful experience, without Positive
    Government Involvement, these projects will fail.
  • These Projects change the existing Balance of
    Power in major ways.
  • The opposition or obstacles include money,
    resources, established interests, publicity,
    greed, spies, secret agents, etc.
  • We have approached the Chinese Government in
    Beijing. Seeking additional support.

Competing Technologies 2aAdding Magnetic Field
  • What happens if we add Magnetic Field to the
    Gravity Machines of Sung and Liang?
  • The electrical energy drawn out is expected to
    drastically increase.
  • If the Magnetic Field is created via
    Electromagnets, what happens to the Energy
    equation?
  • Can we attribute the Electromagnetic Energy as
    Cosmic Energy coming from the Atoms (Electron
    Cloud)?

Competing Technologies 2bEulers Coil
  • What happens if the Energy from Gravity
    Cylinder is replaced by a very heavy
    Electromagnetic Coil as suggested by Euler?
  • The Electrical Energy can then come from both
    Gravity and Magnetic Fields.
  • This combination is covered in the Patent but no
    experiment has been done
  • Let Euler and Team work on it and shine
  • This is an example of Improvement or Surrounding
    Patent to the original Patent

Possible Products7 Pendulum Toy
  • Ideal to demonstrate theory
  • The best explanation of Energy from Gravity is
    the Pendulum
  • Can modify existing swinging toys
  • If the Gravitational Field is replaced by
    Magnetic Field, we can extract Energy from
    Magnetic Fields

  • Great for Demonstrations
  • Many variations possible with different setup of
    Magnetic Fields
  • Can use either permanent magnets or
    electromagnets
  • If Swing (oscillation) possible, vibration should
    also be possible.
  • Low efficiency but good for teaching

Possible Products9 No Vibration Transformer
  • When vibrations are equal on both sides, there
    will be no vibration.
  • However, the flux change will still be there.
  • This is likely to be the most efficient in size
    and may even replace the normal batteries
  • Prototype rumored available from Sung and others
    since Feb 2005

Possible Products9a No Vibration Transformer
  • Claim from Japan is that existing Electricity
    Generators change Mechanic Energy into
    Electricity. The newly invented Electricity
    Generators change Magnetic Energy into
    Electricity. Please Explain?
  • One possible answer is that the Permanent
    Magnets/Electromagnets act like mirrors.
    Mirrors reflect light but are not the sources
    of light energy.
  • Permanent Magnets induce Molecular Arrangement
    and lead out the Energy inherent in the atoms!
  • (Cosmic Energy is Energy within the atom!)?

    ignorant, uneducated, suppressed, etc.
  • With Infinity entering the equation
  • Infinity Infinity Infinity
  • Infinity x Infinity Infinity
  • So long as the increase in population is not

  • How can Insult Training help?
  • The possible temptations would be role played and
    Videotaped first to strengthen the members.
  • The strength and weakness of the members would be
    exposed early before the live event.
  • The cold and hot treatment would be fun.
  • This is expected to be one of the most Demanded
    Courses in the Innovation Center

Comments 6
  • In the financial estimates, the patent income
    alone is over HK20,000 billion. This means over
    HK2.5 million for every Hong Kong Citizen. Is
    this too good to be true?
  • When the inventions replace all fissile fuel and
    will replace all cars, ships, electrical
    appliances, the above estimate is no
    exaggeration.
  • This will make history.

Comments 7
  • Does this mean the Economic Problems of Hong Kong
    are effectively over (assume that the
    headquarters of the Companies are in Hong Kong)?
  • The answer is yes. We have to realize the moment
    we put Infinity in the Economic Equation, all
    calculations and assumptions will change.
  • Imagine Hong Kong as the sole oil supplier with
    negligible cost, what would happen?
  • The plan is to coordinate with China and
    introduce the technology to the World.

  • Can you narrow the gap between the rich and poor
    in Hong Kong?
  • When we have Infinite Energy and hence Resources,
    we can give much more training and help to the
    disadvantaged.
  • The rules of the game can change to provide
    minimum guarantee and opportunity to all.
  • It is a matter of defining what are Meaningful
    Economic Activities. Let this discussion mature
