Back in early 2000s there were some supposed Early Streamer Emission (ESE) rods that claimed to reduce the need for rods by supposedly initiating the upward stream earlier, causing interception further away from the rod location. That tech has been quite thoroughly debunked (there was a big retrospective study in Malaysia that settled it, iirc). I remember seeing these systems being marketed by quite a lot of serious people at trade shows. Anyway, that's a bit off topic but i meant to say that it's cool to actually see the two streamers on a picture like that.
