a far less sophisticated and elegant, but probably more reliable
approach could be the use of the water cooling system for disinfection, given it can be accessed more or less easily.
The temperature is not only predictable, it is measurable and will be around 90°C at normal operation.
As I've learned lately, 70°C for 30 minutes "kills" covid19 reliably. So if the outer parts of the water cooling system are
above that, it could probably work.
- presumably tortous to implement
- no Perl ;-)
