Static electricity could help run air conditioners about study Recycled Polystyrene Waste to Triboelectric Nanogenerators: Volumetric Electromechanically Responsive Laminates from Same-Material Contact Electrification.

There's potential for energy from the turbulent exhaust of air conditioning units to be collected that could reduce the energy demand by up to 5% and, ultimately, lower the carbon footprint of the system. We could produce this static electricity just from air blowing on the surface of our clever patches, then harvest that energy.

It could but it can not and polystyrene microfibers look like great source of microplastic pollution. See also:

A simpler, more efficient device for harvesting water from the air: Study finds new method to provide drinking water using half the energy

On average 30 min intervals, the NiTi harvester harvested more water (at 0.18 ± 0.027 mL/WH) than the desiccant wheel harvester (at 0.1567 ± 0.023 mL/WH). The NiTi harvester was significantly more efficient than the desiccant wheel harvester (p < 0.01). In addition, the desiccant wheel harvester had a wider range of temperature variation, from 22 to 32 °C.
