Project:
SUSTAINABLE REVOLUTION PART 4 at Linköping University
During spring 2024 a candidate group with Simon, Erik and Richard will use
the Linköping University GREC Lab-Model v.3 for experiments.
The Green Revolution Energy Converter (GREC) sustainable research at
Linköping University will put their own physical GREC LabModel v3 to work.
This unique project aims to answer if a "real world" revolving physical "Work
Generating Volume" will behave as predicted in earlier Li.U theoretical research.
Does theory and reality converge? Is the GREC a future crucial climate-positive
concept for an adjustable clean energy generation?
Linköping University are world leaders in GREC technology and this group is
on the cutting edge.
Background
The severe impacts of green house gas emissions on the global warming is today a
fact. The emissions can be coupled to several different sectors where heat and
electricity production were the sectors with the highest increase of CO2 emissions
in 2021. In Economics and Politics the word ENERGY is often reduced to something
to sell, distribute, consume and tax. Our industrial society is built on that.
In natural sciences energy is larger than that, energy is a property that is not
created nor destroyed, although energy can change in detectable form. This change
in form is what the Green Revolution Energy Converter is all about, to convert heat
energy into kinetic energy in a totally new machine - The Green Revolution Energy
Converter - GREC
- Green: Is NOT to generate Carbon Dioxide and toxic pollutants. Green is NOT to produce waste. Green
is generating clean (fossil free!) energy.
- Revolution: Is repeatedly revolving a Work Generating Volume (WGV) of gas over warm – neutral –
cool - neutral surfaces to convert a heat flow to pressure-volume work.
- Energy: Is a property belonging to anything that is able to interact in the universe. Energy
cannot be created nor destroyed but energy can be transferred between objects. When an object does work
on another object (changing its momentum), the energy of the former (the ability to do work) decreases
while the energy of the latter increases.
- Converter: The form of energy can be converted. The energy of an object is its capability of
producing a force that can do work, as well as its capability of transferring heat. Kinetic energy is
energy of an object in motion, which acts as the capacity to undergo change in position over time.
The GREC converts heat energy to kinetic energy by pressure-volume work. The kinetic
energy may be used "as is", or to generate electricity by connecting a generator to store
and/or distribute its power. Simon, Erik and Richard are investigating this new technology
aiming to be applied both in the electricity production sector and the transport sector.

The Project's Starting Point
A leaking LabModel v3 that needs to be prepared and sealed in order to measure
pressure variations from a revolving Work Generating Volume (WGV) at different
speeds between heat reservoirs of different temperatures.
First Part Project Goal
Obtaining a tight enough LabModel v3 with a motorised revolving WGV.
Overall Project Goal
To be able to revolve its WGV with electric control at different speeds while
logging pressure and average temperatures.
The goal is to retrive logged data in a repeateable form and present it with
reliable extrapolations for much larger volumes.
What distinguishes a GREC LabModel from a GREC Prototype?
A GREC PROTOTYPE should generate a power surplus and be built for a
specific temperature gradient condition. We would base our calculations on a WGV
of 25 to 250 litres of gas or a vapor close to its condensation point. Maybe
running in an environement where you only need an electric switch for the motor
that revolvs the WGV.
In order to construct a prototype made to deliver a certain power requirement
in a particular environment, one must be clear about the limitations of the
concept and test its properties with the variables of the environment. That's
why we need a working LabModel.
A GREC LAB MODEL is a small gadget with a lot of electronics. With a
tiny WGV of only 25 cc the LabModel is really under-dimensioned but it allows
us to study the limits of phenomena with experiments that will help us interpret
what is going on, and which are the dominant factors and their limits, in order
to be able to calculate, construct and set dimension with the support of
established knowledge in thermodynamics, fluid dynamics, heat transfer and
other sciences.
The Green Revolution Energy Converter – GREC – converts HEAT energy to KINETIC energy.
- Heat - Thermal energy are vibrations and collisions of atoms in an object and Heat is when the
thermal energy is transferred between objects (“systems”) due to a temperature difference. Human
detectable form for heat energy is cold and warm. So “Cold” is also heat energy, but less than
“Warm” which is transferring more heat energy.
Heat is measured in temperature. You can never add “cold” but you can take away heat. Heat has a very
strong force to reach equilibrium and it always travels from hot to less hot. Open the door in the
middle of the winter and your room gets cold – this is not adding “cold” but in fact heat leaving
your room until you close the door or until the room temperature becomes the same as outdoors, equilibrium.
- Kinetic energy – energy of an object and objects in motion, which acts as the capacity to
undergo change in position over time. Detectable form is movement like sailing or a mechanical clockwork
to name a few examples.
- Electrical Energy - energy that relates to forces on electrically charged particles and the movement
of those particles, electrical interactions. Preferably detected by an electrical warning sign! Caution!
Risk of electric shock!
The GREC converts heat energy to kinetic energy by pressure-volume work. The kinetic energy
may be used "as is" or generate electricity by connecting a generator.
The GREC Technology
In thermodynamic terms the GREC is a closed system with a
moving boundary where the GREC converts heat energy to kinetic energy.
The GREC heats up and cools down its internal large sliced WGV efficiently,
fast and repetitively, resulting in internal pressure changes.
These internal pressure changes are used by its moving boundary to generate
kinetic energy. You may think of the GREC as a revolving Carnot heat engine
controlled by computer logics. Please find the theoretical presentation of
the GREC on this link:
GREC Theory Presentation
The GREC is a new technological solution to tackle climate change and technologists
at Linköping University are pushing the challenge of a transition to fossil free
energy systems. Their theoretical research, construction and building, and
following experiments of the GREC Lab Model v.3 are very important steps in
a climate positive project that will feed several successful research projects over time...
