Perpetual Motion

THe funny thing about this video is that intends to sell the viewer on the concept of gasoline engine as a virtual perpetual motion machine, but then ends with the admission that it can't be. Only now we realize that it's not just the law of thermodynamics, it's the laws of supply and demand too.

in order for both black holes to exist in a proximity that would allow this faocitnil ball to travel between them (even though it would be compressed to infinitly small partical each time it passed thorough one) they would have to be equally sized and opposite as the ball would have to escape the gravitation acceleration of one black hole inorder to enter the gravitation pull of the other. if there where three or more black holes spaced far enough apart so that thier gravitational pull would not act on each other causing them to collapse, then they could be situated in a circular orientation which would allow the ball to travel through one and accelerate toward the next.While this occurs; will the ball approach the speed of light inturn turn the infintly small particle into a infinity large partical beause the energy would exponentially increase?The ball gets compressed by the gravitational forces of the black hole but the velocity increases and therefore causes the energy to increase????Even though black holes are not really black holes I play along

Sorry, this is misleading. You are cosuinfng RequestContext with a particular context processor.The context processor settings do not determine whether not the context is a RequestContext. This is determined by your view. If you're using a generic view, then it will always be a RequestContext. But if you're using render_to_response, you have to explicitly pass context_instance=RequestContext(request) as the third parameter.If you do this, your context will be a RequestContext, even if you don't add the Request context processor to your settings. Of course, if you don't do that, you won't have access to the request' in your template.
