![]() The Sunpower screen was the motive power for a special kind of explorational vehicle. Today, we would call this kind of "screen" a photovoltaic cell array, or solar panel. A variety of solar panels are available commercially.
At present-day rates of efficiency, six square yards of Amorphous silicon-based solar cells would produce about (100 milliwatts per square inch) x (6 x 36 x 36 square inches) = 780 watts of power.
For comparison, the Ford e-Ka uses a battery pack which consists of 180 individual cells, and is capable of storing 28 kilowatt hours (kW/h) of energy, and weighs a mere 280 kilograms. This vehicle goes zero to sixty in about 12 seconds and is capable of eighty miles an hour. If you are interested in the science, take a look at this solar energy experiment.
Be sure to read about the vehicle described above: Steel Tortoise - grandfather of the ATV from the same novel; that entry has a slightly extended quote. Comment/Join this discussion ( 2 ) | RSS/XML | Blog This | Additional
