Came across this and wanted to share:
"Typically [on-the-road diesel efficiency gains] are in the 2% to 8% range with clean engines burning quality fuel, however I have seen some tests regularly achieve over 10% and up to 20% with older vehicles" -
HHO Injection Diesels by Mark Dansie
"Mark Dansie is a well-known Free Energy skeptic who makes dozens of flights each year to go around the world and check out various technologies."
In other words, Mark sounds like a decent guy and not one who'd
want to support HHO and I can't help liking the way he comes over in interviews I've seen.
So, what's really going on?
