ocean-2

The other day I was thinking, I’m going to invest some money in land, since it has a stable value, or at least, has lasting ‘value’. But then I realized that this has mainly (for the time being) financial value,… Continue Reading →

In the agricultural project that I described in my previous contribution [1], which was initially about the EROI, the energy return on energy investment, I subsequently calculated the effects back to land’input’. But then the thought soon arised: would is… Continue Reading →

The Bionological House

7 maart 2022admin
treehouses

With vegetables, we’ve been doing it for years: most current vegetables never existed, in an autonomous evolutionary process. We as humans have slowly transformed them so that they grow the way we appreciate them, and want them on our plates.… Continue Reading →

Carbon storage: the land-time relation 2/2

20 februari 2022admin
1-tree-island-lone-palm-tree-on-small-island-john-lund

For a new book, I explore the space-time relationship of many human activities, as a measure of our system impact, and to see if there are alternatives that can do with less. Space time in the sense that the conversion… Continue Reading →

I recently was triggered a few times by the term: ‘Energy Poverty’ in all kinds of reports and tweets [1-4] . Usually referred to as having little access to oil, gas and coal, in what is then called the poorer… Continue Reading →
