Compressed leaf "log" invention

[osagebow]

Seen threads on the subject before, I know. But I thought some of you you tinkerers out there might want to check out a history channel show on tomorrow. 10PM I think
Looks like these guys made a log splitter modified to compress leaves into a 8" metal tube for waste bio logs or whatever the term is.

At first blush, I can't see the gas/benefit analysis working out, though.
Couldn't find the trailer, but caught it checking out the "Mankind" series, here's the show site:

I saw that also, but question the real world application. The lignens in bio don't start to flow until a much higher pressure than even a big tonnage splitter could produce. That...and there ain't a leaf in my yard. They get blown into the fields after the first wind hits them.
