There are a lot of people who desperately want to give away their time, money, and expertise for other people’s lives right now. Where should they go? What projects already exist that need their resources, and specifically what do they need? What successful projects can be copied (e.g. hyperlocal lobbying efforts)? What projects should exist but don’t yet?
GiveWell seems like a natural recommendation. They've said they're looking into it: https://imgur.com/lsXsJ7T
But if they already have a lot of cash lying around, donations to them now might not increase the amount of good they can do with it short term. Their 2018 financial statement says they had $26m cash compared to $36m donations from that year, but I don't know how much of that they'd be able to use for this purpose. Oh, I guess "net assets without donor restrictions, $12m" is the relevant number for that?
Still, they're currently my default.

My co-worker and her husband, partially backed by my current employer, have modified the design of a device invented in Taiwan for reducing the exposure of ER doctors/nurses to COVID-19. If you have basic fabrication skills you can build your own using the instructions here or else donate here to help them manufacture more to ship to hospitals already on their waiting list.

Whoops, I already created another "answer". Thanks, did not know about that feature.
