That's exactly what I was just wondering and trying to read up on (I'm incredibly ignorant about this sort of thing)... https://www.quora.com/How-is-air-ionized-and-what-does-that-mean https://www.quora.com/How-is-air-ionized-and-what-does-that-... "Air ionisation can cause the following: forming of ozone molecules Ozone is produced naturally in the stratosphere when highly energetic solar radiation strikes molecules of oxygen (O2), and cause the two oxygen atoms to split apart in a process called photolysis. If a freed atom collides with another O2, it joins up, forming ozone(O3). Most of the ozone in the stratosphere is formed over the equatorial belt, where the level of solar radiation is greatest. The circulation in the atmosphere then transports it towards the pole . So, the amount of stratospheric ozone above a location on the Earth varies naturally with latitude, season, and from day-to-day."

so with a lot of these flying about we can use ozone-depleting substances (ODS and CFCs) once again?

  At the very least, it seems like there might be some prospect of combining the battery and voltage upticking tech here with the likes of the solar-powered Zephyr [1] which can fly at about 20km, which is apparently about the denser part of the ozone layer [2] [1] https://en.wikipedia.org/wiki/Qinetiq_Zephyr https://en.wikipedia.org/wiki/Qinetiq_Zephyr [2] https://en.wikipedia.org/wiki/Ozone_layer https://en.wikipedia.org/wiki/Ozone_layer , in particular: https://upload.wikimedia.org/wikipedia/commons/thumb/c/cb/Ozone_altitude_UV_graph.svg/300px-Ozone_altitude_UV_graph.svg.png https://upload.wikimedia.org/wikipedia/commons/thumb/c/cb/Oz... - ed I suppose it would make more sense to pair the battery and voltage conversion tech with a high altitude balloon covered in thin film PV, so there's less competition between 'ozone generation' and the 'lift generation'.

  No. Per https://en.wikipedia.org/wiki/Tropospheric_ozone https://en.wikipedia.org/wiki/Tropospheric_ozone you see that ozone in the lower atmosphere is a pollutant. We want lots of ozone up in the stratosphere. Blocking UV, well away from us.

    Can we send a bunch of these ion-powered planes to fly on solar power in the stratosphere, more efficiently and rapidly generating ozone than the natural process?

      That's exactly what I wrote in a response to the parent an hour or so ago! :(

      You won't be able to get to the stratosphere with low efficiency propellers. And you would need an absurd number of them to make any difference.

        As someone else suggested before this comment was posted, use a balloon for lift? Maybe combine the whole thing with project loon like internet relays. With a source of thrust like this it would be much easier to keep them where you want them.
