Viktor Schuaberger water power

One can get real far out with vortex engery but this

is for the down and dirty concentration of water power

by velocity rather than pressure head.

As I pointed out in the past a similar effect occurs for air flowing around or being concentrated by an object.  The drop in pressure as the air speeds up allows, in principle, for more energy to be extracted (Bernoulli's Equation).  The only question, as I see it, is backward pressure from the turbine.  Apparently it is not a problem.

I'll play in my spring branch and big creek someday

but in my case my big interest is air intake tracks in

old motorcycle head and combustion chamber turbulence

at pressures the gas is more viscous than water.

In somewhat related fluid flow vien, are foil bearings that

float on air I'm hoping to adapt to crankshaft use.

On the stream flow restrictions I've seen some neat

things like rocks being thrown out of cascades onto

far bank several yards higher than water level. Also seen

series of alternation rotation bowls craved in otherwise

flat rock water 'slides'. Don't know what to make of it

all myself so just offering up stuff that may connect

with someone.
