There's a much cheaper and much older flying platform for mosquito elimination. It's called a bat.
EDIT: or perhaps the bred/genetically modified steriile mosquitos that can wipe out populations in large areas?
Self-perpetuating area-wide techniques like mass release of modified mosquitoes with gene-drive systems is very probably a superior answer if the problem is "there are too many (ie any) human-feeding mosquitoes".
If the problem is rather "what is the coolest-sounding possible way to wipe out mosquitoes", then drone-mounted lasers are in the running.

I was at first confused by Eliezer's requests at the end of Ch. 119. I missed his Author's Notes, which his explains his rationale behind them. I thought I would share in case others missed it, especially because readers on LessWrong may have more elite or broader networks to help Eliezer achieve his new goals.
Eliezer has several other projects he might be interested in. Learn more by clicking the link.
