On efficiency

The turkey waste processing plant is ~80% efficient, but I think the numbers paint a different picture. In this article, Appel claims that 100 btus of energy are extracted for every 15 btus used to power the process (making the process 85% efficient). This would be a 666% power output. At 80% efficiency (what today's article claims), the power ouput is 500%.

This process originated from another developed in the 70s which would put out about the same number of btus as they put in, which would equate to 100% power output or 50% efficiency.

BIG!, I tell you. Really big.
