Solar electrical generator

In an engine comprising a turbine and a boiler, the boiler having at least one boiler wall, heating means for heating the boiler for converting a liquid working fluid in the boiler to gas, the improvement comprising:

• mounting means for mounting the turbine within the boiler such that the boiler and the turbine rotate relative to each other and shroud means in the housing for directing the gas to the turbine, the improvement further comprising the turbine having a shaft, the shroud being fixed to the boiler and the shroud and boiler rotating about the shaft of the turbine, and pump means being mounted through a portion of the shroud for directing the liquid working fluid through the shroud.

In an engine comprising a turbine and a boiler, the boiler having an elongated, generally cylindrical boiler wall, heating means for heating the boiler for converting a liquid working fluid in the boiler to gas, the improvement comprising:

• mounting means for mounting the turbine within the boiler such that the boiler and the turbine rotate relative to each other and shroud means in the housing for directing the gas to the turbine, the heating means comprising means for directing heat energy to the entire length of the boiler wall over at least a portion of the circumference.

In a boiler having a housing for containing working fluid therein, the boiler having an elongated, generally cylindrical boiler wall for transferring heat energy from a source to inside of the boiler to heat the working fluid to convert it from a liquid to a gas, the improvement comprising:

• rotation means for rotating the boiler to present different portions of the boiler wall to the heat source, the boiler containing a relatively small amount of working fluid, the rotation means rotating the boiler at at least a velocity sufficient to cause the working fluid to form a thin film by centrifugal force on the inside of the boiler wall.

A condenser for condensing saturated vapor to liquid, the condenser comprising a sealed system having a secondary fluid sealed within it, the sealed system having a plurality of spaced-apart concentric annular chambers, conduit means connecting adjacent annular chambers, a plurality of annular passageways, one between each annular chamber, means for directing the saturated vapor through the annular passageways whereby the saturated vapor condenses on the annular chambers causing the secondary fluid to vaporize, a heat sink, tube means in the sealed system having a first portion for directing the vapor of the secondary fluid to the heat sink where it condenses and a second portion for directing the condensate to the annular chambers, collecting means for collecting the condensate of the saturated vapor, and means for rotating the condensing means whereby the condensate and liquid secondary fluid are forced to the outside surfaces of the passageways and annular chambers respectively but the saturated vapor and vapor secondary fluid are not moved by centrifugal force so that the centrifugal force directs the liquid through the condenser to their desired location.

A solar collector comprising an array of collector sections on at least one side of an object to be heated, the array extending substantially the entire length of the object and a distance radially outward from the object, each array having converging means for converging the solar rays along a line substantially parallel to the object, collimating means at the line extending parallel to the object for directing the converged rays into parallel paths and reflecting means for directing the parallel rays from the collimating means to the object.
