"pepper with nanopores <100 nm diameter... generic Air-gen effect... water molecules would easily bump into the pore's edge as they pass through the thin layer. This means that the upper part of the layer would be bombarded with many more charge-carrying water molecules than the lower part, creating a charge imbalance, like that in a cloud, as the upper part increased its charge relative to the lower part... runs as long as there is any humidity in the air... KW electrical utility usage"
