Ask HN: What business opportunities might arise from the COVID19 crisis?

Humans are the only species that use toilet paper ... although some Vietnam veterans remember monkeys that wipe with their hands (and throw it at intruders). Design a sustainable alternative to TP that does not require pressurized water. Historical Examples: corn cobs, Sears Catalog, "soft rocks". (I'm winging this guys. Bear with...) What feedstocks are ubiquitous and cheap? What would it take to recycle junk mail into TP?

Some ideas/needs I've thought of:

1. Tools/curriculum for young children education (K through 6th grade primarily)

2. Technique for temporarily segmenting airplanes into smaller compartments

3. Anything related to ventilator supply chain.

4. Test kit supply chain

The problem is that no one knows how long this will take. Ideally a venture would choose something that would hold its value after the crisis is over.

Remote work and everything related to it, video conferencing, cloud sharing, etc.
