Sun focus hydro turbine.
« on: April 21, 2014, 03:56:32 PM »
Parts need. Three swing valves, one floating ball. One hydro turbine. One Solar focus.

Workings. Heated air rises to the surface of the water providing it downward movement. The water movement passes through the hydro turbine and compresses air into the holding tank.

Air movement into the longer cylinder trips open the air release valve which remains open until the cylinder is again full of water.

The lack of moving parts, and near zero friction losses makes this the most efficient of any solar heated air engine.

Can you elaborate a bit on this, please? I am not really understanding your diagram.

The water movement passes through the hydro turbine and compresses air into the holding tank.

I don't think that this will work. The pressure in the holding tank might rise slightly, but when it does you will need a hell of a lot of heat to increase it any further. Why will the water be moving? Buoyancy from the heating effect? Surely this will not cause enough convection to turn the turbine in any significant way?

I'm not sure about near zero. What about frictional losses from the turbine? What about shear stresses, viscous friction, of the surfaces that the water is moving against?

"might rise slightly"

Might not!

Maybe I am not seeing the whole picture here, but what prevents the collected heat from heating both the water as shown and the air all the way back to the turbine, thereby working against it?

You be correct the heated air does heat the water. You be wrong no heated air goes back to the turbine.

For greater power to heat, connect the DaS Valve to the air line and block off the air intact, plus enlarge the to a an expansion chamber, then fill with CO2, easiest done by insertion of block Dry-Ice.
