Why a complete fuel alternative that can also be retrofitted into existing cars would be more efficient than hybrids.

Geez I couldn't even read that whole thing it's like a book. I did skip through using the "Wolf Speed Reading Method" to at least get the meat of it.

Hence my clipping paragraphs that highlighted the main issues. It is a very detailed article, but given the technical nature of the publication, I guess they wanted to illustrate the whole picture including exploded views of each detail like a magnified tech drawing. It would probably make the day of anyone seriously researching/studying the issue with so much info in one place.
