Creating a brighter future

Putting us back in context, the current energy system is operating at too high an 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 REC applications will strongly contribute to these goals.

Here’s where we are today

The concept is in its early stages but nilsinside is working with several partners in Sweden, France and the UK to bring the project forward. The partners understand the huge potential of the motor and its wide applications opportunities within the energy field. These partners are helping in different ways from basic maths calculations and modelling to building a lab prototype.

Even though promising estimations of the REC power output at low temperature differences have been made from the existing demonstrator, these calculations will have to be demonstrated. The good news is that we are getting close to finding these key factors.

FabLab in Brassac, France, is currently working on updating a version of the first REC Lab-Model. The program invested in a CNC cutter which will be used to provide perfect out-cuts for the REC Lab-Model ver 2. The purpose of this Lab-Model is to, in the near future, provide 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 REC motor in the function of temperature difference and wanted power output.

In Sweden, nilsinside is working together with ALMI (Swedish government) and the University of Linköping in order to understand the mechanisms of heat transfer inside the REC and seek new methods of calculation.

In the UK, nilsinside is currently setting up Yin Spin Yang Ltd. which will develop and run a large span of different applications in the UK and worldwide. Yin Spin Yang will also, with the help of partners, build a proof of concept – a prototype which will help industries to go from the “No, it’s too good to be true – don’t believe it until I see it” to the “Holy Spin, this is actually working! Let’s work together!” stage.

nilsinside AB and Yin Spin Yang Ltd. are looking for partners and searching for co-funding to bring the project forward from proof of concept into real industrial applications.
