Solution: driving cars by Kai Neumann

A model explaining some of the obstacles of the transformation towards electric vehicles (EVs) This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the development of the uses of gasoline cars and electric vehicles (EVs) using the KNOW WHY Q...

The price of sustainability by Kai Neumann

Being tired of the complaints that renewable energy is expensive, that we cannot afford the conservation of natural habitats, that not all people can purchase organic products, that our industry looses jobs, our citizens cannot bear the burden of the costs of sustainable solutions, and so forth I started this model. As it turned out it is not as easy as I thought. My original assumption was that any additional expenses should - with a high domestic value creation compared to the import of fossil fuels - ...

Systemic look at e-fuels - shifting the burden creating wrong memes by Kai Neumann

The lack of systems thinking around the topic of e-fuels really hurts.  People need to understand the archetype of shifting the burden (to the intervenor), the vicious cycles from path dependencies and the psychological origin in the fear for change and selfish business interests.  Here some other insights on hydrogen of which I am actually a big fan: https://www.consideo.com/files/consideo/pdfs/papers/eng/ConsideoPaper-BEM-Engl.pdf https://www.know-why.net/model/Ckps4y3iZwQWd6YKcOb6qdQ https://www.consi...

Economy from a systems perspective p9 by Kai Neumann

... still work in progress and soon more .... On my vacation I intended to complete my reading of Kate Raworth's "Doughnut Economics". I looked at this concept many years ago and wasn't fascinated by it but I have come across it several times in different projects since then so I decided to take a second look. I watched her TED talk and I really like her. Still, the concept I find disappointing though I haven't read the complete book, yet. I think it is a normative approach to rethink economics but in or...

Hydrogen dilemmas- not just a question of constraints by Kai Neumann

Just a quick model to put the major arguments around the use and the source for hydrogen into perspective. We need to transform industries like the steel production away from fossil fuels towards use of green hydrogen. In order to shift they need supply. A useful source would be a domestic supply from times when we produce more than 100% of the needed electric power by renewables. However, the capacities for electrolysis would remain unused in times with no surplus of renewable power generation. But if w...

Atomdebatte Deutschland - Politikwissenschaft by Kai Neumann

Kleines Modell zu dem Trauerspiel, das sich gerade in unserer Öffentlichkeit abspielt. Rot/grün kann nur verlieren, es sei denn, wie es gerade passiert, es wird auf das Motiv der CSU hingewiesen. Hinter einigen Faktoren sind Quellen. Möge die Aufklärung beginnen...
