Exciting news from Linköping University! The latest GREC project report confirms proof of concept with experimental results that validate earlier student work. As with previous reports, it's crafted by technologists in classical thermodynamics, comprehensible mainly to their professors and peers. The report includes detailed formulas and well-presented graphs, but it challenges the reader to extrapolate the potential performance of a real prototype. - Their LabModel uses a small work-generating volume (WGV) of 25 cl, while a real prototype at this stage will range from 25 to 250 liters. - They operate at speeds of 1, 2, and 3 Hz, but an initial prototype will rather revolve somewhere between 10 and 30 Hz. - They use temperature gradients of 38, 55, and 75 degrees, but first prototype cases will probably exceed 75 degrees - They managed to use a small tweeter as a linear generator. This shows a fun possibility of using bass speaker elements to generate electricity from, for example, 10 Hz with a volume change that gives a suitable stroke lenght. Page 39 inspires out-of-the-box thinking, really!  Get the summary here: https://lnkd.in/eNmgkxCU 😃

Today a GREC LabModel v3 breakthrough was achieved by a candidate group, Erik Widström, Simon Eriksson and Richard Zetterman, at Linköping University. They are now able to revolve the motorised WGV for experiments in speeds up to 3Hz with logging of pressure! One step closer to proof of concept! Their success rests on earlier research in well-documented GREC Sustainable projects delivered by motivated, successful Technologist groups with dedicated supervisors at Linköping University, Sweden, world leaders in Sustainable Revolving Carnot Technology. https://lnkd.in/eBYUjYv8 #sustainable #heatengine #thermodynamics #fluiddynamics #climatechange

New exciting project at Linköping's University. During spring 2024 a candidate group with Simon, Erik and Richard will use the University's exciting The Green Revolution Energy Converter (GREC) Lab-Model v.3 to work. Linköping University are world leaders in GREC technology and this group is on the cutting edge. https://lnkd.in/ePNxPFmF #heattransfer #heatexchanger #motor #sustainability #cleanenergy #cleanenergyfuture Nils Karlberg

There was never an Almi - nilsinside AB project! Almi's contact person was uncontactable, so the project never got started. We have just asked to finish. Almi will probably get their "climate change money" anyway. However, our previous experiences with Almi are very good.

Owned by the state, Almi is Sweden's most active business developer.  Almi and nilsinside AB are looking for partners who want to build a prototype with us.  A result of this is the following presentation that gives a small overview of how far we have come, what distinguishes the Green Revolution Energy Converter - GREC - from other thermal engines and a brief description of how GREC works.

A thesis with the title 'Thermal Investigation of the Green Revolution Energy Converter: A study on the heat transfer within the GREC in regards of temperature distribution and heat rate' is now e-published in DiVA at this link:  https://lnkd.in/daYnS2iS

#environmentalsustainability. The GREC technical solution to tackle climate change have engaged technologist groups at Linköping University in their challenge of transitioning to fossil-free energy systems. They have contributed to several, well documented GREC climate-positive research projects over time.

Over the last couple of years, students at Linköpings Universitet in Sweden has worked on progressing the Green Revolution Energy Converter - GREC motor concept. During spring term 2023, a GREC LabModel version 3 for empirical research was built testing to relate theory to reality. Further tests showed the heat transport to and from the WGV works at triple speed and the pressure is the same in the entire volume at each individual point in time. This is good news!
