GENERATION OF POWER, STEAM. 57 87. SOLAR CALORIC ENGINE. Ericsson system. This en-gine ran at 420 revolutions per minute in clear sunlight. It was con-structed on the same designas the ordinary hot-air en-gine and ran under thesame conditions. It is calculated that theheat radiated by the sunduring nine hours per day,for all the latitudes com-prised between the equatorand the 45th parallel, cor-responds per minute andper square foot of normalsurface to the direction ofthe rays to 3*5 thermo unitsof 772 foot pounds. Hence, a surface of 100 square feet would givea power of 270,000 foot pounds, or from 8 to 9 88. MOUCHOTS SOLAR BOILER. A is a glass bell, B is aboiler with a double envelope, D is a steam pipe, E is a feed pipe, F is a conical silvered mirror ;G G is a spindle aroundwhich a motion is given tothe machine from east towest by the gearing regulat-ing the inclination of theapparatus on the spindleG G, according to the sea-sons ; I is a safety valve;K is a pressure gauge, andL is a water gauge. Diameter of top 9 feet;45 square feet of silveredglass surface. Boiler of blackened copper 31 inches high, 11 inchesdiameter. Thin glass cover 2 inches larger than boiler. Pressure generated 75 lbs. per square inch ; 11 lbs. of water evap-orated per hour. Used for driving a pump. A sun motor of thistype is now in operation in Southern California, pumping water forirrigation. Reflector 33% feet diameter, 10 horse-power.
