Solar-powered line-focus water heater. This system uses curved mirrors to form a parabolic trough which focuses sunlight onto a tube running above the mirrors which contains water. This heated water can then be used for domestic and industrial purposes. This saves energy and reduces heating costs. It also avoids the use of power-generation methods that produce pollution, such as burning fossil fuels.
