## Development of a mathematical model, material analysis and physical model improvments

At Linköping University Sweden a group of students, Gustav Edholm, John Malmdal, Lukas Haglund, Markus Eriksson and Oscar Magnusson did a full time project "Theoretical Proof Of Concept For The Green Revolution Energy Converter" starting beginning of February and running until the end of March 2022. They have publiched a report with the same title describing the "Development of a mathematical model, material analysis and physical model improvements" included below as a link to Linköping University and the official publication :

### Background

If we are to prevent global warming from exceeding 1,5 degrees we need innovative solutions to be carried out in the next upcomming years. One of these potential solutions is "The Green Revolution Energy Converter" (GREC) which has the potential to change the future in both the sector of sustainable energy production as well as in the sustainable transport sector. The Green Revolution Energy Converter converts heat energy to mechanical energy by heating up and then cooling down thin slices of an enclosed revolving "Work Generating Volume" of a constant mass of gas (WGV). This revolution generates mechanical energy in the form of pressure and volume waves. These pressure/volume waves or rather pulses is in turn used to generate energy by a piston, a pump, an electric generator...
• The greater the temperature difference between heating up and cooling down, the more energy.

• The larger the work generating volume of gas, the more energy.

• The more revolutions per minute, the more energy.

### Technical

Inside the "Green Revolution Energy Converter" the thinly sliced enclosed "Work Generating Volume", the WGV, is revolved in a circular motion between a hot and a cold storage by a "Revolving Shutter" powered and controlled by an electric motor. The electric motor consumes far less energy than what is converted from the warm and cold storage by revolving the sliced Work Generating Volume. In short; the heat energy from the warm and cold storage is converted to mechanical energy by the revolving WGV.

### Theory

The general gas law pv = mRt calculates the maximum power you can get by revolving the Green Revolution Energy Converter one lap. To get the Green Revolution Energy Converter to deliver one lap of power, the Work Generating Volume, WGV, has to be filled by heat transfer only with the available heat on the hot side to generate a pressure / volume increase and then moved to the cold side where the WGV by heat transfer drains its heat to correspondingly decrease its pressure / volume. This wave or pulse of pressure / volume change may be used as force in a piston and / or diaphragm, like operating a linear generator or anything else that is able to use this movement. The power of this movement is power per unit of time, so you want to fill and empty WGV as fast as possible. In other words, you want as fast heat transfer as possible.
