What is the basic principle of tidal power. That fluid can be air (wind) or liquid (water). For example, in a conventional fossil fuel power plant, the temperature of the steam leaving the boiler may be 1,000oF. This book is a step in that direction—suggesting more cost-effective and less environmentally intrusive methods for creating power sources from rivers, the tides, and other sources of water. A tidal barrage works similarly to a large hydropower reservoir dam, but it is placed at the entrance to a bay or estuary. Actual available wind power can be calculated. Tidal energy is produced by the surge of ocean waters during the rise and fall of tides. The production is the form of pulses (2 pulses every day and each pulse lasting about 4 to 6 hours). Hydroelectric power is a renewable energy source which harnesses the power of moving water to produce electricity. A proposal for the Severn Barrage, if built, has been projected to save 18 million tonnes of coal per year of operation.

This book aims to contribute to a better understanding of the new electricity generation technologies by addressing a diverse audience. The flow is the volume of water which can be captured and re-directed to turn the turbine generator, and the head is the distance the water will fall on its way to the generator. Ocean waves contain tremendous energy. In river and tidal generation, the input resource flow is slower but also steadier than it is in wind or solar generation, yet the level of water turbulent flow may vary from one place to another. Later, in 1966, the France Tidal Power Station on the France River in France became the world's first tidal power station. 1. The maximum power output from a shrouded water turbine used in tidal energy applications is equal to the kinetic energy of the water impinging on the blades, similar to the "run of river" calculation above.
