Nuclear Power von Kai Neumann

Sweden and several other countries decide to resume the use of the widely disputed nuclear energy, withdraw the promised decomission of older power plants and even plan to build new power plants. They argue that we all need cheap energy supply to gain time for the development of alternative energy sources and that nuclear energy is a carbon neutral and therefore climate saving source of energy. The majority of people until recently feared nuclear energy for its manifold risks. The costs of nuclear energy...

Quantitative mini model of job markets and purchasing power von Kai Neumann

This quantitative model is a small excerpt from a 1000+ factors model of a larger project. It allows to simulate the changes of a job market due to changes of available jobs or people seeking for jobs, people choosing to work only part time and a larger part of pensioners. While it would be fairly easy to model it through a classic system dynamics stock and flow structure it was fairly challenging to try it with the iMODELER's possibility to use stocks without delays. That is also the reason why I tried ...

Power2Gas by Greenpeace Energy von Kai Neumann

I was interested to change to a power to gas subscription from greenpeace energy in which they offer to invest into power to gas (wind and solar energy is electrolytically transformed into methane that can be transported with the existing fossile gas network) yet to be built. I disliked that right now there is only a minor proportion of power to gas included in their regular fossil gas supply and that there are too few investors. I argued that they should offer a high priced but consequent product which ...

Fridays for Future - debunking politician's bullshit von Kai Neumann

it is doable, in fact it would cost less, but memes and ill minded politicians serve single interests. unfortunately, there is no clear argumentation against the memes out there. this is just a rough sketch, but as a scientist I have examinded the path to a sustainable future in depth. please ask for more and join the modeling!  students and media need to be a role model for the green factors and explain the turqouise factors: ....

Climate Change - a comprehensive and collaborative model on the arguments von Kai Neumann

This model was developed with the help from the model "Globale Erderwärmung" by MaggerTheGreat from KNOW-WHY.NET.

Energiewende 3 von Kai Neumann

Ein kleines Modell zur Reflektion der Optionen einer zukünftigen Energieversorgung. Das Modell zeigt die wesentlichen Argumentationsstränge. Es können gern weitere Argumente eingebaut oder die Gewichtungen der Zusammenhänge variiert werden. Leicht lässt sich dieses Modell also weiter differenzieren und sogar die einzelnen regenerativen Energieträger oder auch explizit die Option von Thorium-Reaktoren können im Detail betrachtet werden. Vielleicht ist es aber überraschend, dass es keine perfekte Energieve...
