Who said there were no practical applications?!
"Here’s how it works. Wificoin first installs its open source operating system onto a Wifi router. When new users try to connect to it, they get 100 Wificoin, which they can spend for 1 megabyte each of wifi access. If they need more, they can either buy Wificoin with Bitcoin or Ethereum, or they can install the software on a router they own which earns them Wificoin each time someone uses it."
