I recently started looking into ICOs that are connected to a real world economy. Mostly mining, but there are some other good once too.

My favorite so far:
https://www.hydrominer.org/ - here you basically buy an opportunity to mine through their equipment with their tokens
http://esonics.io/ - here you invest in a mining hardware production; this guys have a cool idea on how to re-finance their business thorough exchanging tokens for their products with a discount 

Do you know any others?
