@sophiecentaur thank you for your comments. 5v / 9v is admittedly based on assumed limitations for powering lightweight wearable devices. And being able to run this with a disconnected battery using plate separation sounded like a very attractive effect to power ratio. I'm unaware of multi kV...

Thanks @Baluncore for all the input. I imagined two possible configurations. The fan sizes I was looking at were between 80mm and 120mm, so say 100mm avg and it's in a square housing. So that's sending air down a square pipe (a very short one but same dimensions). I had pictured the fan as being...

@sophiecentaur I read the paper again (link below) having skimmed some of it previously. Results were generated using atomistic simulations of protein structure. Standard procedure apparently. There is no call for how field is generated, just that it generates a 100kv/m - 10million v/m. (max 3...

That's true but that filter could be a virucidal like copper. The type of transmission (fomite) results in less severe acute stage disease than respiratory transmission. So ultimately better collect it and deal with it than breathe it. But you're right it might need periodic uv treatment or...

So only looking at the workings of capacitors for a few days and witnessed some threads (not here) saying they could be harmful even despite low voltage input as they still could store v high amounts of electricity?? And the electric field requirements to kill viruses of hundreds of thousands...

Thanks @DaveE So on that note could one negatively charge another plate (MESH) further upstream again to trap as much gunk and virus as possible before even hitting the dust filters. I'm basing this on the premise that particles in the air are mostly positively charged, (the reason negative...

OK, was going to get round to it eventually but did want to avoid egg on face if a non runner from the get go or if a health hazard. I am trying to see if it is physically viable to blow a certain airborne virus through a 500k+ v/m electric field before it gets inhaled while maintaining...

Thanks guys, So I'm looking at the breakdown of air which seems to be 3million v/m? Which was to conveniently bring me to a follow up of how this electric field might be maintained under airflow of maybe 30-60 cfm. If air is the dielectric does it have to be still? (and sterile) If one needed...

Hi all. This might be a complex thread or line of questioning if the first question passes the human safety test. I was advised to post at undergrad level. I myself am a layperson without an education in physics/maths so if anyone would find the patience to explain answers in terms a layperson...

Great thanks for this

Hi again, so just about to post and it wants a prefix. Basic high school, undergrad etc.... Does that refer to my education in physics (none) or the complexity of the question? The thread if it survives question one (safety) is in regard to electrostatic plates at a few micron distances and...

Thanking you

Have a question on electrostatics, voltage and airflow. Do i just hit new post and go at it?

A layperson who often bumps into tricky physics questions which require somebody who knows more than me.
