Yeah, I read the article on the guy doing the conversion, he seems to pull his numbers out of his....hindquarters.
Not totally out of his @$$, but I noticed he's esentially running the bio-d engine off a bio-d/Hydrogen mix to get a more complete burn of the diesel, and more power (doubling the power and efficency if you believe the guy).
But he's only quoting FE numbers in MPG. So he's doubling the efficency of the
bio-d.
No mention of all that hydrogen he'll be burning.
The same guy is converting the Hummer to run bio-d/hydrogen through a turbine as a series hybrid. He says it'll do 0-60 in ridiculous and "conservatively" get 60mpg.
