"Thinker" vs "Doer" gets pretty fuzzy: "changing laws" certainly involves a lot of thinking, as do ~all of the highest-impact things you might be considering "directly improving the world". I especially have trouble seeing how you could classify Farmer's work in Haiti as something other than an attempt to directly improve the world.

But riffing on your "not just the people who have told others that they should", and emphasizing the "that", perhaps the line is whether someone's primary work has been persuading other people to be more altruistic and/or effective? In which case I'd probably put MacAskill, Ord and Singer, and Rosling as "Thinkers" and Karnofsky, Wise, and Farmer as "Doers". But several of the folks in the "Thinker" category still did substantial "Doer" work (Rosling's hands-on public health work in Africa, MacAskill's co-founding 80k, Ord's cause prioritization, Singer's political advocacy and donations).

Thanks for sharing!

The play tells the story of a group of teenagers who, upon learning that a mere five dollars can save an African child’s life, formulate a plan to steal artwork and donate the proceeds to Oxfam International.

While I'm sure almost everyone here doesn't need to hear this, better to be explicit:

  • $5 is only about 0.1% of the cost to save a life via the best known global health and development charities

  • If you're looking to donate in this area GiveWell's recommendations are very likely better than Oxfam

  • Don't steal to donate proceeds to charity

This is relatively minor, but it would it be possible not to show a cookie notice to people loading the site from countries such as the US where these notices are not required?

Interesting! I hadn't realized people had started using the term this way!

That's a box fan CR box

A filter with PC fans isn't a "CR box" -- a Corsi-Rosenthal box is specifically a design based on box fans. For example, Wikipedia, US Davis, Clean Air Crew, and the Corsi-Rosenthal Foundation mention only box fans.

Good point! I'm used to houses with the older systems (steam, forced hot water) that are common in the Northeast and wasn't thinking about this effect.

Efficiency in terms of fraction of removed particles wouldn't decrease, but because CFM will decrease efficiency in terms of CADR will too.

Ceiling fans are generally reversible, so you could have the ceiling fan blowing air up and mount the filters for airflow in the opposite direction. I haven't tested this configuration though!

There is actually this study from the national labs that indicate filters hardly need replacement at all. I think it is even worse than razorblades that grow dull - filters last forever!

That study is looking at nuclear facilities, but I'm not sure it generalizes to environments with more particulates in the air. In a dusty enough environment your filter will surely get clogged up to the point where you're not able to move much air through it!
