Finally, because air humidity diffuses in three-dimensional space and the thickness of the Air-gen device is only a fraction of the width of a human hair, many thousands of them can be stacked on top of each other, efficiently scaling up the amount of energy without increasing the footprint of the device. Such an Air-gen device would be capable of delivering kilowatt-level power for general electrical utility usage.
Indeed, but at utility-scale you also likely have some energy to spare for powering an electrostatic dust filter at the intakes...
My parents' house had a Honeywell brand electrostatic air filter in front of the air handler that wasn't cost-prohibitive to operate, and didn't have a drip pan or anything so I don't think it stripped moisture either. We'd just toss the large metal filter cartridges in the dish-washer periodically, which barely fit. They didn't pose a significant air restriction, unlike conventional pleated physical filters.
> Note: Avoid portable air cleaners and furnace/HVAC filters that intentionally produce ozone. Ozone is a lung irritant. Note that in some cases, air cleaners that contain electrostatic precipitators, ionizers, UV lights without adequate lamp coatings, and plasma air cleaners may have the potential to emit ozone. Both the California Air Resources Board and the Association of Home Appliance Manufacturers maintain lists of air cleaners that have been tested and shown to emit little or no ozone.
> Electronic: Air cleaners that are listed as "Electronic" may be capable of generating small amounts of ozone, but have been tested and found to produce an ozone emission concentration less than 0.050 parts per million. This category includes ionizers, electrostatic precipitators, PCOs, hydroxyl generators, devices with UV light components, and other electronic air cleaning technologies.
I imagine electrostatic precipitators would fall into that category
Maybe it could be pre-filtered air in a closed loop? However, this already seems like magic to me, so I am unsure if it is possible to filter/recycle the air and still come out net energy positive. Alternatively, maybe there could be some kind of washing step where the plates are washed/air forced through/voltage applied to remove debris.
