Well my minds been stuck on this little tid bit recently [quote= Someone talking about Viktor Schauberger]most energy sources in use today run on pressure. Like a steam engine, energy is used to boil water to make steam at high pressure. Then, that steam is released through the steam engine to make mechanical energy to run electric generators. But Nature uses the opposite process. It uses a temperature drop to produce a spinning low pressure mechanism to produce a Tornado or a Hurricane. These storms release tremendous amounts of mechanical energy in the form of winds.[/quote] I'm thinking of that if some sort of 'tornado' were mechanically sustained, contained in a bubble of forward time dilation passing into a second region of 'slow' dilation and finally utilized to generate power it would work. Since if the bubble 'popped' you'd be hit by thousands of years worth of output all at once and turned inside out. But singularities do sound much easier.
