Philips T8 Type B Direct Wire Ballast Bypass tubes can replace existing T8 and T12 fluorescent tubes. They offer a simple rewiring solution to maximize energy savings while reducing maintenance costs by removing the ballast from your fluorescent system. Philips T8 Type B Direct Wire Ballast Bypass LED tubes eliminate the need to replace your ballast due to failure down the road, while also being able to replace both T8 and T12 lamps. Philips T8 Type B Direct Wire Ballast Bypass use a double ended design which makes the product safe and simple to install. In residential settings, this light bulb is perfect for laundry rooms, kitchens, garages and basements and in commercial settings in retail offices, parking garages or industrial spaces. Unlike fluorescent bulbs, Philips T8 Type B Direct Wire Ballast Bypass linear T8 LED light bulbs contain no mercury, offering a safe and sustainable, solution, while operating well in cold temperatures.

Since the first edition of this book in 1983, HVDC technology has continued to expand and few power systems can now escape its influence. This thoroughly revised text develops the coverage in the first edition, describing the variety of reasons justifying the use of DC transmission as well as the basic concepts and techniques involved in the AC-DC and DC-AC conversion processes. It has been fully updated and enlarged to include descriptions of the widening applications of DC, the current state-of-the-art thyristors and other semiconductor devices, and the new developments that continue to make HVDC a competitive technology. The book should be of interest to practising engineers and researchers involved in the power industry. It will also be of assistance to lecturers and students in the power systems and power electronics disciplines.

The Earth's resources are being consumed at a rapid rate. If we do not solve this problem, we will all be extinct soon. This book discusses in layman's terms the various areas of research into converting the Sun's energy into ways the energy can be stored and put to practical use. The only inexhaustible supply of energy that we have is energy from the Sun. Green chlorophyll has the ability to convert energy from the Sun into organic compounds that we and other animals eat. This is nature's solution to the problem of capture and storage of energy. Scientists are working to develop photosynthetic processes suitable for commercial development - a complex but not insoluble problem. While the development of atomic power holds great promise for the future as a replacement for fossil fuels that are rapidly being depleted, the underdeveloped countries have a particularly vital and immediate interest in devising low-cost sources of energy. Farrington Daniels spent many years studying the possibilities of converting the sun's rays into mechanical and electrical power, and in this volume he covers all aspects of the subject of solar energy. Without stressing mathematical and engineering details (though including complete references to the sources of this kind of information), he describes the full range of the experimental work involving collectors of solar radiation, cooking and heating water, agricultural and industrial drying, storage of heat, solar furnaces and engines, cooling and refrigeration, photochemical conversion, and many other uses. No one is better qualified than Mr. Daniels to give an overview of the present knowledge of the field and to point to future research possibilities.
