Solar Powered Website: Uptime for 2020

In 2020, our solar powered website obtained an uptime of 95%, meaning that it was offline for 444 hours or 20 days. Unsurprisingly, most of the downtime is concentrated in the winter months.

The graph above (click to enlarge) shows battery storage capacity in relation to the weather in Barcelona from January to December 2020. Yellow is sunny, grey is cloudy, blue is rain. From May to November, we were online without interruption for almost 6 months.

The data were collected and visualised by Roel Roscam Abbing and David Benqué.

The lavet is a typically Dutch invention that was mainly used in social housing in the 1950s and 1960s. It was produced up to 1975, with a total production of about 1 million. The lavet is somewhere between a sink and a bathtub. It consists of a plateau with a raised edge, in which on one side is a 40 cm deep tub with a diameter of almost 60 cm. Unique to the design is the multi-functionality. The lavet fulfilled the functions of a bathroom and laundry room but required ​​only one square meter of space. [Read more…]

Follow the Science?

Two great articles in The New Atlantis 2021 spring issue:

“Scientific “objectivity” emerges not from the unique cognitive qualities or neutrality of researchers but from their critical engagement with each other’s work…. Though the political harms of misplaced certainty are now much discussed, we only hear about one side of the equation. The trouble always seems to be with “conspiracy theorists” who fail to face up to reality, to scientific fact. But the relationship of “debunkers” to certainty is not all that different… Conspiracism and scientism are jointly preoccupied with certainty. They enjoy a fantasy in which experts are uniquely able to escape the messiness of politics, discern the facts plain and simple, and from their godlike viewpoint turn back to politics and dispense with it. Both seduce members of open, uncertain societies with the promise of a more simply ordered world… ”

“What “follow the science” has amounted to, ultimately, is a shifting of agency for decision-making onto scientific and bureaucratic bodies like the CDC and the WHO, while obscuring the fact that the decisions to be made remain fundamentally political … The “science” that politicians have claimed to follow rarely resembles the centuries-old process of making informed guesses, testing hypotheses, assembling data, and asking new questions in an effort to teeter toward the truth. It is rather a void at the center of technocratic politics into which leaders cast their responsibility.”

This Website is Designed to Last

“My proposal is seven unconventional guidelines in how we handle websites designed to be informative, to make them easy to maintain and preserve. The guiding intention is that the maintainer will try to keep the website up for at least 10 years, maybe even 20 or 30 years. These are not controversial views necessarily, but are aspirations that are not mainstream—a manifesto for a long-lasting website.”
