Nanomaterial usage; advancements in cloud seeding

[Jason N]

Scientists advance cloud-seeding capabilities with nanotechnology | MIT Technology Review

I've been keeping an eye on this technology for some time now to see how it plays out in multiple scientific/research and more practical to Industrial/Military use. Uses of AGI have been around since the 60's but side effects of material use was not always understood and there were some potential harmful side effects. There are some branch efforts using this line of technology with different materials, one of them perhaps graphene, that are highly interesting and may be to some of you here.
