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 😃

Developing a new powerful sustainable motor – the Green Revolution Energy Converter (GREC) - for a clean energy future!
Om oss
nilsinside AB is an innovative technology company developing a powerful sustainable motor- the Green Revolution Energy Converter (GREC). It can transform low temperature differences into power and has a wide range of applications. This heat engine is an extremely efficient energy converter that we believe will change the way communities and businesses internationally generate emission-free and clean energy. This is a highly scalable, low cost, zero carbon engine that makes the GREC an outstanding competitive solution. We are in an early stage of our journey and about to finish our prototype which will provide the data we need as proof of concept. The GREC has a wide range of applications across multitude of sectors where there is a temperature difference. Are you an industry with waste heat? Are you looking for new renewable energy solutions? Then we would like to partners up and explore specific application! Key applications include: - cheap clean high power energy generators which can deliver continuous off-grid electric and/or mechanical work, - industrial waste heat to energy, - geothermal motors, - direct solar to motion, - innovative technology within the energy storage sector, - emission-free technology within the transport sector... The technology behind this heat engine has a simple concept yet so innovative and powerful. It builds on established knowledge in heat transfer and thermodynamics. The GREC is a Carnot engine using an electric motor to move its "Work Generating Volume" between a hot and a cold reservoir. This generates pressure pulses that in turn generate work (connecting to a piston, a turbine, a pump, an electricity generator…). - The larger the volume of air, the more energy. - The greater the temperature difference, the more energy. Today's external heat engines are very limited in power due to limited cylinder volumes. However the GREC can benefit from lower temperature differences and be built for much higher power output.

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. Please check out this link: https://lnkd.in/eFQTdukv and please don't hesitate to get in touch if you have any questions, thoughts or comments! nils@nilsinside.com
