BLACK FEMALE ENGINEER PLACES EXPENSIVE GIANT
CRYSTAL ON SCALE. CU MACHINE CUTS CRYSTAL INTO
PRECISE WAFERS.

DRAWING SHOWS HUGE MODERN BUILDINGS WITH SOLAR
PANELS ON ROOFS WHICH COULD PROVIDE ALL ENERGY
NEEDS FOR THESE BUILDINGS, IF RESEARCH SUCCEEDS
IN REDUCING COSTS.

DRAWINGS SHOW AT SANDY CORPORATION IN NEW MEXICO
ANOTHER APPROACH IS TO EMPLOY SOLAR COLLECTORS
TO SUPPLY AL THE HEAT, ELECTRICITY, HOT WATER TO
A SMALL OFFICE BUILDING.

01:06:40
CU PHOTO ELECTRIC SENSORS ATTRACT SUN THROUGH
ANGULAR CYLINDRICAL MIRRORS UNTIL ALL LIGHT
ENERGY FOCUSES ON TUBE IN CENTER. OIL IS SENT
THROUGH TUBE, HEATED, SENT TO STORAGE TANK,
WHERE IT HEATS STEAM WHICH SUPPLIES POWER TO
GENERATOR..

MCDONNELL DOUGLAS CORPORATION DRAWING SHOWS
SUN REFLECTING FROM FIELD OF MIRRORS AIMED AT
BOILER ATOP TOWER. ENGINEERS PLACE WEIGHTS ON
HUGE MIRROR SECTION TO LEARN HOW FLAT IT WILL
REMAIN IN HIGH WINDS.

01:07:52
ENGINEER TESTS POST THEY DEVELOPED, WITH LASER
BEAM. IT STAYS TOTALLY STABLE UNDER EXTREME
TEMPERATURE, WIND. REFLECTED BEAM ON WALL SHOWS
HOW IT SLOWLY MOVES ACROSS WALL.

01:08:19
SUN RAYS CAPTURED THROUGH A MOSAIC OF FIFTEEN
FLAT MIRRORS, DEVELOPED BY MARTIN-MARIETTA
CORPORATION, IS REFLECTED DIRECTLY TO A GIVEN
SPOT BY A SCIENTIST, CAUSING A LARGE SHEET OF
MATERIAL TO BURN PROFUSELY.

01:09:16
SCIENTIST GIVES HAND SIGNALS DIRECTING, BEAM OF
LIGHT TO GRID OF HOLLOW BLACK TUBES, THAT
ABSORBS 99 PERCENT OF THE ENERGY, AND RAPIDLY
HEATS WATER FLOWING THROUGH IT.

01:09:39
WORKER EXAMINES BOILER ATOP TOWER WHICH CAN
SATISFY THE NEEDS OF 1500 PEOPLE.
