There are some intriguing ideas here, but it would take an engineer to verify if the reverse supercharger would really double the horsepower of an engine. Until someone can actually run the numbers and work up a real CAD on it, all we've got are diagrams.

As a side note, Mercedes-Benz is claiming incredible efficiency from its Diesotto engine, an engine that uses a diesel-like compression cycle to combust gasoline. Mercedes-Benz says it's working on a prototype, but hasn't really shown off anything that is verifiable.
