I've been waiting for a commercial device to come out after hearing about this a decade ago. Some kind of simple blackbox that kills mosquitos in a reasonable vicinity with low power requirements that's also rechargeable via USB. Possibly add a big battery and make it a USB charger. I don't think 30cm distance is far enough for much usefulness, feels like commercial viability means at least 1m if not 2m. 30cm is 'put object by the food' use case and not much else, and mosquitos aren't really into food. Perhaps it could work by tent openings but not sure.
