Reflexion on thorium reactors by Kai Neumann

this is just a first scetch of a cause and effect model ... if you look at the matrix of the factor thorium reactor you will recognize that this model is dominated by balancing feedback loops (...) you may contact me (kai@ilsa.de) to get a copy of the model or even to collaboratively model it with me and others in any way: many insights and happy modeling Kai

Are Resource Costs Macroeconomically seen Costs? by Kai Neumann

In many of my client's models and I have to admit in some of my own as well the depletion of resources simply leads to an increase of resource prices which decreases spending power and competitiveness. But if we widen our system's boundary we can at least put into perspective this view. This qualitative model shows why.

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...

Rise of nationalism and populism in the world by Kai Neumann

Just started this model while listening to a podcast from Fareed Zakaria and his interview with Colin Powell and Madeleine Albright ....  I think there is a lot to add to this so please join the modeling using to collaborative link :-)

iM-AI on Ukraine (ChatGPT) by Kai Neumann

.... again, just one of our trials to generate cause and effect models using AI / LLMs, in this case ChatGPT....

Sustainability Mini Model by Kai Neumann

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...

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...
