a great book, one that opens your mind to the possibilities in the scientific fields, this is the kind of books that our children should be dealing with in schools, the same for his books on history and religion, but then it would be harder to control the masses if they were properly educated as opposed to the drivel that is being forcefed to our children, an absolute must if you really want to educate yourself to the truth regarding free energy and the wasteful society that we are being forced to live in. If we are to have any hope of a future on Earth then we must stop using vital resources like oil, An engine cannot run without it, Its Of the Earth for a reason,[not to run our industry but to keep the place temperate], we strip our planet we die, The powers that be know this but still do nothing, because the pension pots are linked to oil prices, so we lose the need for oil, they lose control. We as a race will soon be forced to look for alternative sources of power, WE DO have the knowledge, we have always had the knowledge, but until our respective governments can find a way of taxing it, making millions out of it then we wont be having it anytime soon....
