That's the problem what we have isn't perfect, well it isn't for the majority of us at least, but some are profitting and where there is the surety of profit why seek change.
The other thing of course like the cure for cancer, it involves too many industries to actually seek a cure, if a cure or in the case of energy something else is found to be viable, there ends a lot of business and it is with our existing economic environment industry just stopping whilst the transition is made to new technologies, perhaps this is too dangerous, so reliance on old truths and lies have to continue, as it works at least.
But it interests me the president of the USA where he said he wanted to rid America's dependance on Middle Eastern oil by creating a new technology, well, it seems he has been kicked into touch on that idea, just like our own mealy mouthed excuse for a leader has not implemented his fuel tax regulator that he went on so much about before he gained office.
