Bobby Amarasingham’s Water Propulsion Technology
This video features one that could be great for water
propulsion, making it safer, for swimming pools and for fish.
It uses three cone shapes on a rod, the middle one of which
moves forward and backward. As it moves forward the water is
“reflected” against the forward cone to push water backwards;
and as the middle cone moves backward, it pushes water back with
it then as well. So the “forward-backward” action of the middle
cone results in pushing the unit forward in the water.
The advantage is that it is much safer than a propeller, and it
may be more efficient than a propeller. Bobby says it is around
60% more efficient than propellers.
The prototype toy he built (photos shown in the video) was so
popular, all the
ar, all the kids wanted to play with it at the beach. “Can I
have a try?” “Can I have a turn?”
He would like to see this patent-protected technology move
forward.

FROLOV : New Sources of Energy ( 2021 )
The English inventor Bob Amarasingham started producing
his electricity generators back in 2009. He planned to set up
production facilities in China because there are optimal
prices for components. His 3-kilowatt autonomous power
generator should be priced at around $750, and it could hit
the market in 2012. This technology is very simple. Some small
electric motor turns a rotor with weights - eccentrics
that work on the cardioid trajectory in the vertical plane. As
a result, due to the forces of inertia, additional momentum
torque appears in the system (at half the cycle of rotation of
the weights) and the output power of the electric generator is
many times greater than the power consumed by the drive. We'll
take a closer look at the Amarasingam generators some later.
Unfortunately, there are no great achievements in organizing
the mass production and commercialization of this technology
in 2021.
The GDS Technologies Group can be named as an interesting
example of free energy innovations. These power generators are
already on sale, power to order, from 5 kW to 50 kW. The
author is looking for partners for the development of the
production. We discussed a license agreement for Russia with
him in 2014. The acquisition costs for generators of this type
are around 500US dollars per kilowatt of installed capacity...
Inventor Bobby Amarasingham successfully tested his AOGFG 12
kW generator in December 2010. This device includes rotating
weights and electric drives that produce constant torque. When
starting, the drives consume about 500 watts (acceleration)
and then only 50 watts, while the generator delivers 12
kilowatts to the useful electrical load. Rolls-Royce engineers
have tested this device and prepared contracts with
manufacturers in China. The estimated market price for a 12 kW
drive (excluding the price of an electric generator) was US $
5,000. The dimensions will not be more than 1,5 cubic meters.
The weight of a 6 kW machine is approximately 120 kg, for a 12
kW machine the weight is about 200 kg.
Note that this principle takes advantage of inertial
(gyroscopic) effects resulting from the rotation of
eccentrics, so such machines can be much more compact than
simple unbalanced wheels. For example, Dmitriev’s and
Amarasingam's generators are similar, but for Dmitriev’s
device the weight of a 5 kW machine will be about 1,000 kg.
The advantages of Amaragingam technology are obvious.

One of the first Amarasingam Generators
The Amarasingam’s generator is quiet and rustles like a
conventional air conditioning system. The plan was to produce
around 100 thousand generators per year, initially machines
with an output of 3 kilowatts, 6 kilowatts and 12 kilowatts. A
small generator (3 kilowatts) can cost around $ 750 in mass
production. This generator was supposed to be on the market in
2012 but we never saw it.

Bobby Amarasingam and his 12 kW Generator
I am a representative of Amarasingam in Russia, but for many
years I have not found a serious partner in Russia for the
development of this technology. Nobody is interested to start
mass production of this generator. In 2012 Amarasingama's
marketing strategy was changed. He stopped selling licenses
and looked for partners to build power plants to get profit
from the sales of electricity. You can find the contacts of

I will briefly explain the
principles of operation of this
machine at the level of my
understanding. A small electric motor turns the rotor with
weights - eccentrics that describe the trajectory of the
cardioid in the vertical plane. An analogy is the inertial
propulsion drive by author Thornson, but the rotor of
Amarasingam does not turn in the horizontal, but in the
vertical plane of rotation. Fig. 20 shows that the rotor on
the left is heavier and the rotor on the right is lighter. In
such a situation an additional torque is exerted on the rotor
axis due to the force of gravity.
Much more additional torque, however, is provided here by the
centrifugal force, which generates strong kinetic momentum in
the part of the eccentric trajectory. Therefore, Amarasingam
generators can be called inertial gravitational machines. The
freewheel on axis periodically provides the generator with
additional torque when the eccentric change the radius of its
rotation.

In 2011, Bob Amarasingham told a reporter for an English
newspaper about supporters \of Fusion Energy: "They spent $
500 billion trying to find a solution when the solution was so
simple that even a child can figure it out."
Water Displacement Drive System
GB2473510A
[ PDF ]
A water displacement drive system which produces jet flows of
water as a result of forwards and reverse motion of a piston
member 2 is disclosed. The drive system is fixed on a water
vessel below the water line and comprises a forward fixed domed
member 1, a rear fixed domed member 3 and a movable piston domed
member 2, movable between a position where it lies within the
forward domed member and a position where it surrounds the
rearward domed member. Movement of the moveable piston member
between the two positions producing the jet flows to provide a
thrust to the vessel. The drive system may be powered manually,
by use of a pendulum motion weight system (Fig 2), by use of a
vertical moving dynamic piston weight system (Fig 5) or by the
use of a flickable flywheel (Fig 7). The application also
discloses a water displacement pump apparatus.
