  • Description

    IT'S RELIABLE...WILL PROBABLY LAST BILLIONS OF YEARS, AND IF YOU COLLECT ITS ENERGY FROM ABOVE THE EARTH'S ATMOSPHERE IN SPACE, IT CAN BE DONE CONTINUOUSLY. THE SUN...A GIGANTIC NUCLEAR FURNACE THAT AFFECTS EVERYTHING ON OUR PLANET FROM WEATHER TO RADIO SIGNALS.

    AT THE GOLDSTONE STATION IN CALIFORNIA, A TRACKING DISH IS BEING USED TO SIMULATE AN ENERGY SATELLITE IN SPACE. IT SENDS AN INVISIBLE BEAM OF MICROWAVE ENERGY TO THIS RECTENNA WHICH REPRESENTS A GROUND RECEIVING STATION. THE MICROWAVE IS CONVERTED TO ELECTRICITY AND POWERS THE LIGHTS YOU SEE HERE. THIS IS A SMALL SCALE DEMONSTRATION OF HOW A SOLAR SATELLITE WOULD SEND ITS POWER BACK TO EARTH.

    BY BUILDING HUGE SOLAR SATELLITES IN SPACE, NASA BELIEVES SOME THE SUN'S TREMENDOUS ENERGY CAN BE CAPTURED TO LESSEN OUR DEPENDENCE ON MORE CONVENTIONAL FOSSIL FUELS.

    FOR SHEER SIZE, A SOLAR SATELLITE WOULD BE UNPRECEDENTED. A STRUCTURE 35 TO 40 SQUARE MILES COVERED WITH SOLAR CELLS...ABLE TO CAPTURE THE SUN'S ENERGY 24 HOURS A DAY, AND BEAM IT TO EARTH. ONE SOLAR SATELLITE WOULD PROBABLY WEIGH FROM 100 TO 150 MILLION POUNDS -- AS MUCH AS TWO WORLD WAR II BATTLESHIPS.

    SOLAR SATELLITES WILL COST BILLIONS OF DOLLARS, BUT OVER A 30-YEAR OPERATING LIFE, THEY SHOULD BE ABLE TO PAY FOR THEMSELVES. THE COUNTRY'S PROJECTED ENERGY NEEDS IN THE EARLY PART OF THE NEXT CENTURY WILL BE 2- TIMES WHAT THEY ARE TODAY. DR. KRAFT FEELS WE COULD BE PRODUCING 20 TO 30% OF OUR TOTAL ENERGY BY THAT TIME USING SOLAR SATELLITES, WITH EACH SATELLITE GENERATING 10,000 MEGAWATTS. FIFTY OF THESE STATIONS WOULD PROVIDE ALL OF THESE STATIONS WOULD PROVIDE ALL OF THE POWER THAT IS BEING PRODUCED IN THE UNITED STATES TODAY.

    SPACE SOLAR POWER....PERHAPS THE MOST EFFICIENT WAY TO COLLECT ENERGY FROM THE SUN IN THE YEARS AHEAD.
