100 MW total Rosch Thrust Kinetic Generators in operation
Technology harnesses power of rising floats using pressurized air,

and 100 MW power plant designs targeted for utilities. Media, industry, and

Pure Energy Systems News
Here's a great Earth Day present! This is part one of a two-part story regarding
Last July we reported on a buoyancy power company incorporated in Switzerland, Rosch
Innovations AG, that has developed a clean energy technology that uses
compressed air to cause sealed chambers to rise through water, due to the principle of Archimedis (lifting force),
after which the air is released and the weight of the chambers brings the
chambers back down through the water.
They claimed that the amount of energy required to inject the compressed air is
much less than the amount of energy that is able to be extracted by connecting
generators to the rotating system. Back then, their demonstrated prototype
produced 12 kW output being powered by 4.2 kW. The ecological benefits are
obvious, as this system would produce no pollution nor consume any fuel
(producing enough to keep the input requirements satisfied).
Then, on April 11, I received an email from Ashtweth Palise that contained a
couple of brochures that portrayed a company that now has product in the
It says the power plant design is TάV-approved, and that plant
designs are available to licensees (targeting utilities) in 5 MW, 40 MW and
100 MW sizes. These are targeted for utility scale production of
power. The plans call for the buoyancy chambers to be installed below ground
Their brochure states that the cost of electricity production using their
system is around 3 Eurocents per kilowatt-hour (3 US cents at present
exchange rates), which is more than half of what photovoltaic plants and wind
farms are able to achieve. This takes into consideration that the KPP can run
24/7 as a baseload energy plant producing power continuously, not depending on
the availability of the sun or wind, and maintenance costs. This is actually
easily competitive with conventional grid utility pricing in most areas of the
world. For example, here in Utah, USA, wholesale power from the grid is 4
cents/KWh, and Utah is one of the most inexpensive places in the world for
How it Works
The brochure gives the following description of how the older prototype
functioned: (slight editing)
The device gets started by a "Start" button on the command cabinet. The PLC (programmable logic controller) turns on the air compressor that only after several minutes gains necessary "operating pressure" within the reservoir.
The PLC further detects the pressure within the reservoir via a probe and then opens an electro-motorized pneumatic valve. Once the valve is opened, the compressed air enters the pipe and goes to the bottom of the well, where it
pumps the water out of the lowest system chamber (float).
Under influence of Archimedes Law, this chamber (float) gains thrust toward the top, making the entire system rotate clockwise.
At the moment when the next chamber gets in the lowest position of the system, the mechanical valve of the pipe that distributes compressed air from the compressor reservoir connects onto the chamber valve. As soon as the connection is made, the chamber gets filled with compressed air, as well as every other float, one after another. The movement turns a generator.
A certain number of rotations should be obtained for the precise generator performance, which will result with full and stable voltage of 3x380V with stable frequency of 50 Hz.
Only when the full speed is obtained does the PLC engage the load to the generator via a three-phase switch. The measurement
cabinet contains sound and visual indicators of device performance as well as instruments for measuring inter-phase voltage,
voltages between each of the three phases, as well as the frequency of the exiting voltage.
"Our technology center with a team of 20 colleagues, based in a
beautiful landed property comprised of 1300 sqm of office space and shop floor is a beneficial resource."
Yesterday I was finally able to have dialogue with one of the principals in
the company, Etmen Dohmen, Chairman.
He said that they have 100 MW total worth of power being produced continuously
by several Thrust Kinetic Generators presently in operation. I don't know of any
other exotic free energy technology that comes even close to that in power
production in operation.
He said they have a showplant in Germany that demonstrates a 5 kW
coming in May, they will have a 100 kW demonstrator, with the system raised above ground,
11 meters high, with windows around the water chambers so you can see the system
Here's their tentative schedule for demonstrations of the 100 kW system:
- First week of May: "Pre-opening" for journalists
- Second week of May: for investors, banks, utilities
- Third week of May: open to the public
Note that these dates are different from the 5 kW Gaia-Energy
demonstrations which begin this Saturday. (Story)
Here's a photo of their tube for the 100 kW demonstrator with windows, being
unloaded from a truck.
Here's that tube next to the 5 kW tubes for Gaia-Energy's home-power version
of this technology.
Gaia-Energy in Germany/Austria, which is
a licensee of the technology, is making a 5 kW home power system available for
sale. See our separate
story today about that development. Roberto Reuter, CEO of Gaia-Energy, said
that previously, Rosch had a two-meter version of the technology in Plexiglas,
so you could look inside. He didn't say what happened to that prototype.
Rosch Innovations AG is focusing on larger systems for national electricity providers.
Dohmen said they are setting up a 1 MW demonstration plant in Croatia, as
well as a 5 MW showplant in Slovenia. And in September, they will be setting up
a showplant in
He said it will take about 9 months to build a 5 MW plant.
I asked him if they'll be ready for an onslaught of orders.
He said that they plan to grow slowly, and that one of the natural limitations
to their growth is a special kind of neodymium used in their generator, the
supply chain of which will limit their manufacturing to 2 GW production capacity
per year, at least at first. That is puzzling to me, because I would think that
the generator head would be the last thing that would hold them back, since that
is an established technology with a sufficient supply chain.
They are presently inundated with thousands of visitors, so don't be surprised
if they are a bit slow in responding to phone or email inquiries.
You can get their website and contact info on our Rosch
Innovations AG feature page at PESWiki. It's also in their brochures. Their
website is presently being overhauled and is not online.

GAIA's AuKW Demo - To track the demonstration under way in
Germany from April 25 to May 6 of GAIA's AuKW production prototype, which
is the first of 500, as a self-sustaining system (no input power),
producing 4.8 kW net output continuously. [Presently SEEKING: Visitor
