Social Snorkel
The coronavirus (especially if attached to a water(/sputum) droplet), has a still-air diffusion speed of your average brick, relying on air currents to spread : 5-6 feet up from the spewing orifices and the air is relatively clear, so... | |
a length-adjustable (think automobile antenna), lightweight, bifurcate-tube/filter/mask combination with robust head-straps.
The snorkel/filter assemblies attach to the mask via a standard NATO connection, enabling optional adaptation to existing NBCW fashionwear ; adapters for older/foreign model
gasmasks available on request.
(and thankyou Jutta, for the new category)

Can there be a rigid carbon-fibre version ? |
|

Er, how low are the overhead power lines in your part of the planet ... ? <Sniggering/> |

I seriously considered picking up a mil. gas-mask, but cartridges are difficult to find and (IIRC) only rated for a few hours (and no clue how to rejuvenate them). |
|
| |
Side-topically, I've considered going clean-shaven to make the piddly masks I do have more effective, but even unseen razor-burn would provide more attachment points. |

Can't be done- single use, and discard. Once unsealed, they degrade anyway irrespective of use, so one that's been opened and put aside is junk after a couple of days. |
|
| |
Consumer-grade non-sealing (medical type) masks are more a gesture of intent than practical protection. They'll reduce droplets and particulates, but not stop them, and besides they leave the conjunctiva completely exposed. |
|
| |
Bizarrely, your aquatic mask-and-snorkel suggestion works (mechanically) quite well. But since the majority of users blithely ignore the necessity for post-exposure decontamination protocols, it's all a complete waste of time. |

The snorkel should be a flexible hose held up by a drone. Then with the air intake over 6 feet above the crowds no filter is necessary. |
|
| |
Intake high up; exhaust (unfiltered) at head height ... |
|
| |
Of course, if you're infected, the unfiltered output is going to contaminate all those around you ... |
|
| |
It would be an interesting study to correlate height
demographics with infection rates and immune
system loads and conditioning. Is this another
evolutionary advantage of being tall? |
|
| |
That's entirely possible. Droplets will be drawn downwards by gravity... the infective miasma will swirl around somewhere below average mouth height. |
