New energy ideas and future technologies don't necessarily need to be over-unity to be effective alternatives. Generator's can still be made more efficient and we can still make more efficient ways of turning them.
Victor Schauberger's implosion technology combined with new highly effiecent generator technology might be a more practical solution to explore than some of the more exotic approaches.
Where can you get a "schauberger" copper shaped funnel to experiment with? well I discovered "metal spinning", but am awful at it.. people better than I can spin a sheet copper metal funnel over a mandrel and duplicate the funnel that creates a "clean vortex of water droplets" to experiment with..
