Abstract: Systems, methods, and software described herein provide enhancements for managing and comparing data from multiple information sources. In one implementation, a method of operating a comparison service includes obtaining, from a plurality of data sources, data objects in a plurality of formats corresponding to an event, wherein the data objects each comprise data items for the event. The method further includes maintaining a data structure for the event, wherein the data structure relates data items of similar data type from the plurality of data sources. The method also provides identifying a user request for a summary of the event, generating an event summary based on the data structure, and providing the event summary to the requesting user.

Abstract: The present invention relates to the generation of substantially pollution free energy by utilizing hydrocarbons to create electrical energy for interconnection to local transmission lines positioned between an electrical generating facility and an end user, while re-injecting exhaust fumes or other byproducts into a subterranean formation.
