Earlier this month, the Director of the Chief of Naval Operations Energy and Environmental Readiness Division, Rear Admiral Kevin Slates, posted a thought provoking piece entitled "Reconsidering Energy Use in 2013". According to his posting, "Increases in petroleum prices created a $500 million increase in fuel costs for the Department more...

Canadian engineer Louis Michaud of Vortex Engine has undertaken much research into producing artificial tornadoes that may drive wind turbines. Michaud based his research on the occurrence of natural tornadoes, cyclones and the counterpart, waterspouts that occur over water. There may be potential to adapt Michaud's earlier research at several more...

Abstract This paper is an attempt to emphasize on the importance of the non-conventional energy sources of which small hydropower generation is one. It deals with the cogeneration of hydro power along with thermal power stations. The paper describes how it will be effective to increase the overall efficiency of more...

While the engineers of the Mayan Empire are credited with having developed suspension bridges and buildings that could survive earthquakes, they are also credited with having initiated several innovative feats of hydraulic engineering that date back well over 1000 years. The rock dams they built at high elevation along the more...

Just like developers and contractors, affected people need enforceable rights in dam projects. The public interest in cost effectiveness and environmental protection must be safeguarded by clear standards. Yet the dam industry is currently trying to roll back rights and standards that have been established over the past 20 years. more...

In a desperate bid to attract investment in Cambodia's failing power sector, the government is offering guaranteed power revenues to Chinese companies willing to finance and build large hydro dams, and sell their entire output to the financially-strapped state utility, Electricite du Cambodge (EdC). First in line for the new more...

The Northeastern United States receives a large percentage of its electrical power from Canadian hydroelectric power dams. California imported electric power from the hydroelectric power dams of British Columbia during a power shortage. Canada is also America’s largest foreign supplier of oil that can only be extracted from frozen tar more...

Advances that are occurring in energy conversion technologies and in the marine shipping industry could strengthen the case for high capacity pumped hydraulic energy storage at Niagara Falls. At the present time the United States leads the world in the number of pumped hydroelectric installations of over 1,000 megawatts, followed more...

Fog fences have been used for decades to collect the water droplets from dew and fog after which the moisture is sent to storage systems via piping systems. These fences are typically located at higher elevations near coastal regions where moisture is carried in by winds that blow over a more...

In conducting depreciable life studies of almost every type of fossil-fired and renewable power generating technology over the past nine years, I have found hydroelectric generation to offer the best combination of economic and environmental advantages. Yet this energy alternative has failed to attract the investment necessary to expand existing more...
