This document proposes an alternative financing system called a Clearing Union that facilitates peer-to-peer trade using credit rather than currency. It describes how the Clearing Union would work by having sellers and buyers issue IOUs to each other that are guaranteed collectively rather than through banks. Defaults would be covered through fees paid into a shared pool. The document then discusses how this model could be applied to financing capital projects through partnerships where investors and users share risks and rewards without interest. It provides examples of how this could work in the energy sector by creating pools that fund renewable energy projects and energy efficiency upgrades.
