One of the purest Coasian solutions today is the new phenomenon of Internet crowdfunding . Here rules are enforced by computer algorithms and legal contracts as well as social pressure. For example, on the Kickstarter site, each funder authorizes a credit card purchase to buy a new product or receive other promised benefits, but no money changes hands until the funding goal is met.  Because automation and the Internet so reduce the transaction costs for pooling resources, project goals of only a few hundred dollars are frequently crowdfunded, far below the costs of soliciting traditional investors. Other crowdfunded projects have raised over a million dollars, like the Arkyd-100 space satellite telescope funded on Kickstarter in June 2013.  It would seem to be a clear instance of a Coase solution when a public good that always required government sponsorship in the 20th century can be efficiently organized from 18,000 individuals' self-interest (including rewards such as an orbital "selfie", and five minutes of observation time donated in their name to find potential killer asteroids).
