Yeah, be very wary, its a public secret that water at vaporization emplathy expands 1600 times into vaporized water, steam et al. It's the most phenomenol fuel additive ever, but people have died for trying to market water injection, and sooo much crap about how it wouldn't work. Look, George Bush, oilman, chicken hawk, understands these things, because actually you can make an engine that when spun up starts to heat up from internal friction, and has a front and back fan, when hot enough it will run on heat and depending on the materials used, could run for a very long time providing heat and torque, but if you build it, a billionaire will give you a lot of money to sign a paper, and if you break the rules of the paper, you will die, because you're going to need to give it to someone like Kim Un or the peoples party of China, where they actually understand that oil isn't the end all be all. Once the tankers quit running, there is no need to police the seas, so many billionaires will see their income come to a standstlll, and Hartmann is a dreamer. It won't happen until it's 135 in New York and New York has gondolas you take from pizza joint to pizza joint. I hope you read this Tom and you need to go underground until you can get a million of 'em built, and distributed to Brazil, anywhere we don't have a footprint.
