Truth for who?
Eric,
the fact is that Oil Companies have spent and continue to spend multi-billions of dollars on finding, refining and exploiting oil - if there were "free energy" devices that really worked guess who would be selling them at far, far lower cost yet higher prices than oil? Besides the plastics industry, lubrication and a hundred other applications would still make extracting oil a fairly profitable enterprise.
Here at the HabZone we're smarter than the average mark that free-energy cranks and frauds try to flog this garbage off to - guess what, thermodynamics really does work.
