Does the CEO Get a Pass?

Charlier asked ten years ago whether tidal power had come of age (Charlier and Justus 1993); one may query whether, in general, does Conversion of the Energy from the Ocean get a pass? It is remarkable that the problem of tapping ocean energies remains resilient for so long. The matter bounces back periodically. Yet, positive […]

Wrap-up

An attempt at defining the viability of tidal energy generated power was made as recently as 2005 (Wood), however the rise in oil prices has not been fully taken in account and a revised schedule is timely. The European Commission funded CAOC[194] which put in place funding and a platform enabling devices developers, wave and […]

New Technologies

A new perspective is perhaps added to utilization of tidal stream (current) by Mueller and Baker (2005) in their analysis of conversion to electricity of energy produced by marine energy converters, using direct drive electrical power take-off (cf. 7.14 p. 138). Taking into account the electrical properties of the topologies of these ma­chines, problems of […]

Public Acceptance

To reduce emissions the UN Development Program, but also the Royal Dutch Shell Company long range planners, suggest the use of renewable energies. The price of these, however, must be made competitive with that of conventional fuels. Be it mentioned here that the steady rising cost of oil, automatically contributes at nar­rowing the price gap. […]

Innovations and New Thoughts

Although some authors had expected a resurgence of interest in TPPs (Wilson 1983) after completion of the Annapolis-Royal (Nova Scotia) plant, there was no sudden take-off. Neither did the in depth study of a Severn potential TPP, the feasibility studies for a Garolim TPP (Republic of Korea) and for a Gulf of Kutch (India) plant. […]

Climate Alteration and Energy Shortage

Global warming and high oil prices have renewed interest in sustainable energy, with solar, wind, biomass, hydrogen fuel cells, tidal and wave power getting most attention. But researchers in Norway and the Netherlands, known for their water tech­nology know-how, say there is room for other alternatives given the world’s ever­growing appetite for energy.[183] If climate […]

Turbines

Requirements and aims of turbines for TPPs have changed and bulb, Straflo, Darrieus and other turbines may, in some cases yield their place to other types of turbines. In an effort to reduce research costs, Japanese engineers have examined the possibility of converting turbines designed for tapping wave power into turbines for tidal power.[177] The […]
