Heck, pay the restaurant owners rent to use them — now you’ve solved two problems.
Heck, tell the restaurateurs that when we’re done using their ovens we’ll rip them out and install shiny new ones. Problems that can be solved by throwing money at them are good problems to have right now.
Hospitals have ovens anyway, the ones in their cafeteria kitchens if nothing else. But even if that weren't the case, they could just send somebody to a local store and buy one. They could have it purchased, installed and operational by the end of the day.
But I'd still agree with you.
A residential clothes dryer isn't that much cooler than the temperatures they target in this study. Just use a rack or turn off tumble (if you can).
Employees: N95 masks sir
Customer: can I also order one?
