Do-it-yourself air cleaners could be a cost-effective solution for classrooms

What do you think of this idea?

Quebec classrooms could all be equipped with an air purifier to be assembled for about a hundred dollars per classroom. That’s what this Radio-Canada article explains in which we discover the Corsi-Rosenthal box that was designed to reduce the risks of transmission of COVID-19.

The principle behind this do-it-yourself air purifier is to reduce the virus particles that people breathe by adding a few filters to a ventilation system. The first model made by one of the two co-inventors, Richard Corsi, was later improved by Jim Rosenthal, the president and CEO of a filter company in Texas. The two engineers then designed an air purifier that is quite simple to assemble and can effectively clean the air (a University of California study looked at this).

The box consists of four MERV13 filters and a square fan. The whole thing is taped together. Ideally, the filters should be replaced every six months. This video shows how to assemble a Corsi-Rosenthal box.

In Quebec, there are currently no plans to use the Corsi-Rosenthal box. However, a few people have decided to install the boxes in certain schools in Quebec. This is the case for Pierre Elliott Trudeau Elementary School in Gatineau. The school received a government grant to purchase the boxes. Moreover, the construction of the air purifiers could be a very interesting activity to do with the students!

We know the verdict in Gwyneth Paltrow’s case and it’s the end of a bizarre saga

It’s the end of a strange saga to say the least!

In what looked like a media circus and a grotesque Hollywood sketch at times, the civil trial of Gwyneth Paltrow, who was sued by a man who accused her of seriously injuring him during a skiing collision, ended with a favorable verdict for the star.

The jury composed of her “peers” has indeed retained her version of events, as well as that of her children and witnesses from her clan, to the detriment of the man in question, the plaintiff, Terry Sanderson.

The latter is therefore recognized as the culprit in this case of ski accident in Utah, and ordered to pay $1 symbolic to Gwyneth Paltrow.

The jury declares that “100%” of the responsibility of the case is on Sanderson, to the great relief of Paltrow.

The latter offered a few words to her accuser at the exit of the courthouse…

“I wish you well,” she reportedly whispered Sanderson, reports The Guardian and Entertainment Tonight.

Donald Trump indicted, the world stopped for a minute

It is now a done deal.

While many doubted the ability of the Manhattan prosecutor to complete his case to formal charges against a former U.S. president, in this case Donald Trump, it is now a successful mission for him and his office.

Indeed, we learned late yesterday that not only Donald Trump will be indicted for his involvement in the case of payments to the adult actress Stormy Daniels, but that no less than 30 charges could be filed against him, reported CNN in the evening.

A case that we will follow with attention, like the rest of North America and the world, of course.
