PREFACE The adjudication of applications for water licences under the Water Act and, where required, land tenure under the Land Act for a waterpower project requires information to define the project and to assess the impacts from the construction and operation of the project. The Project Definition is the information used to determine the basic conditions for any water licence or land tenure that (more…)

Waterwheels first appeared in Egypt in around 200 BC. These early waterwheels were aligned horizontally and could be powered by oxen. They were used to raise water to irrigate the land and to power millstones for grinding grain into flour. Their use quickly spread throughout the Mediterranean. The Romans brought waterwheel technology to Britain. By 1086 when the Domesday Book was produced, there were (more…)

Hydropower produces almost a fifth of the world’s electricity and supplies 92 per cent of electricity derived from renewable sources, yet only a third of the world’s potential resources have so far been developed. This is particularly surprising as there is great scope for it in countries where the need for electric power is greatest. Sustainable hydropower is a renewable, safe, clean, and reliable source (more…)

Introduction • DOE Hydropower program eliminated in 2006 • $10 million appropriated in 2008 (no funding requested) • $3 million requested for ’09 • The majority of ’08 funds will be distributed to industry, academia and others via competitive solicitations • All water power technologies eligible to apply DOE has been involved in (more…)

Most Energy Production Requires Water and All Regions of US Vulnerable to Water Shortage •Thermoelectric Use = 38% of all withdrawals •U.S. coal, gas, and nuclear plants use 136 billion gallons of fresh water daily to generate electricity –Approx 3% of water (4 billion gallons/day) consumed •Energy Project Could Threaten Water Supply in Salina, Kansas –McClatchy-Tribune Business News, November (more…)

Power Supply: There are two classes of power failures: failures Interruptions or loss of electrical service external causes such as severe storms. The devastating effect before power failures and water shortages occur in or water supply for an extended period of on power systems by major natural disasters can cause order to be better prepared during an emergency. time. widespread outages over a long period of (more…)

There are two parts to this investigation: the fi rst involves building a rain gauge and the second involves building a water wheel. If suitable, the class can be divided into groups, each preparing either the rain gauge or the water wheel. YOU WILL NEED A number of one litre plastic bottles • Water resistant plasters or duct tape • A graduated cylinder • A permanent black marker • A number of large plastic (more…)
