What are the technological consequences of $100 a barrel oil?
Very little it would seem. An electromagnetic answer to energy generation and propulsion, compatible with all established laws of physics, can be built for a few hundreds of dollars, while families go without each week to pay their fuel bills. The information to build the device is available for free on this website, is endorsed by major American multi national corporations, has been published at leading scientific conferences, and has been widely replicated by home experimenters. All I can say is ordinary Americans, Europeans, should perhaps take a look at the way their countries are run, and ask themselves what exactly is going on. Why does the physics community continue to spend billions on hot fusion, trying to solve an energy crisis any competent home experimenter can fix for a few hundred dollars? May I suggest as a starting point for your research, the film End Game: Blueprint For Global Enslavement. You may find some of the answers there.
