Whereas the beauty of Bordynuik's machine is that it runs itself from its own off-gas produced by the cracking process... a closed loop system requiring relatively little external energy for start-up.

One of the problems with those backyard P2O BBQs is that they require large amounts of external energy to run such as wood logs in your links. This is why in none of your links is there a scaled up process and only makes a tiny bit oil.
