Emission Free Energy – Creating a Brighter Future
The world's current energy system is burdened with high
environmental and economic costs—the transport sector alone
accounts for roughly one-quarter of greenhouse gas emissions
due to polluting combustion engines. Moreover, a substantial
amount of energy is lost as waste heat in industrial
processes; estimates suggest that between 30% and 50% of
the energy input is dissipated as unusable heat. This
inefficiency wastes valuable resources and exacerbates
global emissions, making the transition to a zero‑carbon
economy even more critical. Innovative solutions are urgently
needed, and the GREC motor technology is poised to make a
significant contribution.
Updating Energy Focus - Here’s where we are today
The GREC concept remains in its early stages,
yet its enormous potential is clear. With GREC projects
in Sweden and France, we are actively seeking partners from
around the globe to help drive the project forward. We welcome
both financial support and hands‑on collaboration—from
fundamental mathematical modeling to the construction of
our next working prototype.
Champions of Zero Carbon Transition
Early tests using our initial
"wooden" Lab Model v1 produced promising pressure pulses at low temperature
differences. Although that prototype encountered some issues
(it eventually got stuck), it provided valuable insights
that have shaped our subsequent development efforts. Our
work is fueled by the shared commitment to a zero‑carbon
future, and we believe that GREC has a vital role to play
in the energy transition.
Progressing Lab Models
At FabLab in Brassac, France, we have built a
new version—Lab‑Model v2—inspired by the first "wooden" version.
Thanks to a newly built CNC cutter at FabLab, we can now
produce perfectly precise CAD out‑cuts for our upgraded model.
Lab‑Model v2 is designed to study the critical parameter:
the Heat Transfer Coefficient (HTC). Obtaining a reliable
HTC will not only validate our existing calculation methods
and models but also unlock more advanced simulations. Even
though this promising model encountered challenges in a
forced experiment (it got stuck when tested a little too
early), we learned valuable lessons from building it directly
from the computer model, and it has served as an excellent
pedagogic tool in our following calculations and simulations
at
Linköping University, Sweden.
Advancing the Project with HTC Research
In Sweden, the University of Linköping has
successfully advanced the GREC research with several fully
documented projects since 2021 including calculations and
simulations of the internal heat transfer mechanisms within
GREC. Linköping University designed and built their own LabModel
v3 and and 2024 they performed repeatable experiments with
volume change work. A direct conversion of a temperature
gradient to electricity with a linear generator was demonstrated
by connecting a simple loudspeaker. Since autumn 2024 ICAM
School of Engineering in Toulouse joined to contribute to
the GREC project with valuable valuable research and also
consolidating earlier work. These combined efforts form the
foundation for planning our next intermediate small prototype
rated at 50W, which will undergo extensive studies and experiments
on the ICAM state‑of‑the‑art DepTH-LAB-platform. With improved
HTC understanding, we will be better positioned to dimension
a large volume GREC motor. The equation that calculates the
desired GREC power output will appear. Main variables include
“revolving speed”, “temperature gradient”, “work generating
volume size” and of course the HTC. These initiatives promise
to refine the GREC technology further, bringing us closer to
scalable, emission‑free energy solutions.
