In recent years I was a Fellow of the Technical University of Eindhoven, more precisely working with the Building Physics department, in particular with Prof. Wim Zeiler, Installation Technology. And we had interesting discussions, because we strive for the same… Continue Reading
What I feared was confirmed: Bill Gates’ new book is a noncommittal plea for innovation, technology and economic growth. Sold as providing the ultimate solutions to our climate crises, the book doesn’t get much further than measures we already know… Continue Reading
In recent years we have seen the Sustainable development goals of the UN appear more and more often as a stepping stone for all kinds of initiatives. [1] And that, however well-intentioned, is not always a good thing. I wrote… Continue Reading

By now its obvious: the way we are currently dealing with climate, environment, raw materials, food, biodiversity, will not help us prevent disasters. But what then? The struggle and discussion on solutions is in full swing currently. Just look at… Continue Reading
When can we expect a real CO2 lockdown, some wondered, after reading my previous comtributions. Good question. Months ago, someone also asked how I saw the future in 20 years, following an article about predictions from 20 years ago[1]. That… Continue Reading
1 Tonne per person per year. CO2 emissions. That’s where we have to go. Comparable to the R-value of Corona. If we above that, we contaminate the atmosphere too much and it becomes out of control. And it is now… Continue Reading
