some very interesting details

1) says lasts for upto 24 hours on surfaces using fogclean which is comparable to ZNO

2) says around $20k per month in consumables for a fogclean machine based on 144 litres per day. that means

a) a single fogclean machine uses 240k of Natshield a year so 100 of them is $24m of Natshield

b) it only works out around $5 a litre for the Natshield in bulk, this means it’s incredibly cheap to make and hence the margins on the consumer version in little bottles must be astronomical
