From Space to Earth: The Story of Solar ElectricityHarvard University Press, 2002 - 224 oldal From Space to Earth tracks the evolution of the technology of photovoltaics, the use of solar cells to convert the sun's energy into electricity. John Perlin's painstaking research results in a fascinating account of the development of this technology, from its shaky nineteenth-century beginnings mired in scientific controversy to its high-visibility success in the space program, to its current position as a versatile and promising power source. |
