Classifying an iPad as an eReader is a bit misleading IMHO. I would have never made the connection if it wasn't mentioned in the article.
The intensity of light needed on an iPad to read comfortably is much higher then a backlit eInk reader e.g. a Kindle Paperwhite. Personally it doesn't affect me very much on such devices, but it would be interesting to see if there is a noticeable difference.
> VPN as a protocol is dying.
VPN is not a protocol, what you're referring to is probably OpenVPN, but there are multiple alternatives. It's even possible to use pure SSH as a VPN.
Clouds can also just evaporate if the temperature is hot enough, like in a desert.
Regardless I think it's better to use this kind of method for cloud-seeding then the pumping chemicals into the air, which seems to be the common method.
