120’2022 (2022-04-30) – Sköna maj välkommen, mer än någonsin på mycket länge!

Today, I learned about:

In my earlier post of 122’2020 (2020-05-01), I talked about the importance of this day in Sweden. It is then that the Swedes celebrate the arrival of Spring in many festive ways. But due to the COVID-19 pandemic, it has now been three years since that could be done in the traditional way. I am therefore very happy that today represents going back to the traditions, and as an alumni of Chalmers University of Technology, the most important thing is of course the parade of trucks disguised as settings for various events during the preceding year, the so-called Cortege.

In my earlier post of 365’2019 (2019-12-31), I also mentioned the result of a scientific activity on Chalmers that looked utterly interesting, how to capture and store solar energy up to 18 years. Now I am pleased to show you the developments after that. As you can see in reference #1 below, Chalmers together with mainly researchers at Shanghai Jiao Tong University, China, are now proceding with a system that does all that.

Today’s header photo, sent to me by my good old friend Dina Giltinan, shows the Grand Harbour in Valletta, Malta. Thank you, Dina, for yet another contribution to my blog ! (I earlier showed another photo from Malta in my blog of 247’2016 (2016-09-03).

That’s what I learned in school today!
