Wind and Solar Power Systems: Design, Analysis, and OperationThe search for clean, renewable energy sources has yielded enormous growth and new developments in these technologies in a few short years, driving down costs and encouraging utilities in many nations, both developed and developing, to add and expand wind and solar power capacity. The first, best-selling edition of Wind and Solar Power Systems provided the most complete and modern treatment of renewable energy. This second edition continues the tradition by offering updated and expanded coverage of this growing field. The book begins with individual sections devoted to wind power and solar photovoltaic technologies, their engineering fundamentals, conversion characteristics, ...
Made of ABS Plastic. Features Super Bright 1-Watt 2X LED. 11 continuous years of burn time on LED or 22 years of burn time when in the on position only at night. 8 hours charge in sunlight or room light will provide up to 10 hours of continuous light - can be charged over and over again. Holds a single charge for over 3 years and comes fully charged. Does not need to be stored in the sun - throw it in your glove box or drawer and three years later, just turn it on. Back up battery has a 7 year shelf life. Roll it up in a sleeping bag and forget you own it - turn it on 7 years later; then simply put it in the sun or room light for a day and have a 3 year solar charge again. Features power source indicator lights - red light is charging, yellow light is solar power, and green light is back up battery power. Treat it like a regular flashlight as it is always ready to go because it's always gathering light (recharging). You won't need to replace batteries that cause landfill pollution. Hybrid Solar Lite is 100% water proof up to depths of 80 ft. and it floats. Extreme temperatures do not affect the light - very durable and guaranteed for life. 4.75 in. L x 1.875 in. W x 10.25 in. H ( 0.35 in.).
Even as concern over climate change and energy security fuel a boom in solar technology, many still think of solar as a twentieth-century wonder. Few realize that the first photovoltaic array appeared on a New York City rooftop in 1884, or that brilliant engineers in France were using solar power in the 1860s to run steam engines, or that in 1901 an ostrich farmer in Southern California used a single solar engine to irrigate three hundred acres of citrus trees. Fewer still know that Leonardo da Vinci planned to make his fortune by building half-mile-long mirrors to heat water, or that the Bronze Age Chinese used hand-sized solar-concentrating mirrors to light fires the way we use matches and lighters today.With thirteen new chapters, Let It Shine is a fully revised and expanded edition of A Golden Thread, Perlin’s classic history of solar technology, detailing the past forty years of technological developments driving today’s solar renaissance. This unique and compelling compendium of humankind’s solar ideas tells the fascinating story of how our predecessors throughout time, again and again, have applied the sun to better their lives and how we can too.
