Creating a brighter future

Putting us back in context, the current energy system is operating at a too high environmental and economic cost and the transport sector is responsible for around ¼ greenhouse gases (GHG) mainly using polluting combustion engines. The world urgently needs to transit into a zero carbon economy and the GREC thermal applications will strongly contribute to these goals.

Here’s where we are today

The concept is in its early stages and nilsinside with locations in Sweden, France and the UK is open for partners in the whole world to bring the project forward, and to share the huge potential of the GREC engine and its wide applications opportunities within the energy field. We need financial support as well as direct support to the project in different ways from basic maths calculations and modelling to building our next real prototype.

Even though promising estimations of the GREC power output at low temperature differences was shown by the first "wooden" Lab Model, these calculations will have to be repeated. (The "wooden" model got stuck, unfortunately) The good news is that we are getting closer to finding these key factors.

At FabLab in Brassac, France, we are currently working on updating the first "wooden" version of the GREC Lab-Model. FabLab invested in a CNC cutter thar we used to provide perfect out-cuts for a new GREC Lab-Model version 2. The purpose of the Lab-Model version 2 is to, in the near future, provide us with a fundamental parameter called HTC, the Heat Transfer Coefficient, which will bring the project to a new exciting level.

The HTC is the key to verifying the already exciting calculations methods and model. More importantly, it will unlock further simulations regarding the dimensioning of the GREC motor in the function of temperature difference and wanted power output.

In Sweden the University of Linköping made a successfull study to document and simulate the mechanisms of the heat transfer inside the GREC, and to document methods of calculation for this internal heat transfer. This research continues at University of Linköping

In the UK, nilsinside is setting up the "Solar2Work" project. which will develop and run a span of different "direct solar to motion" applications in the UK and worldwide. Solar2Work will also, with the help of future partners, build a proof of concept or rather a complete working prototype of the GREC in a solar thermal application. GREC aims to slow down climate change.

nilsinside AB and the Solar2Work project are open for partners and searching for co-funding to bring the project forward from proof of concept into real Green Revolution Energy Thermal Applications (GRETA) without emissions. The carbon dioxide free choice!
