Energy ocean waves

Ohta simplified the nomenclature and named the process as mechanolysis [214], The theoiy puts restrictions on the particle size, which should match with the crevices and hence it should be between 1 to 10 pm. Although mechano-catalytic water splitting is simple and does not involve any toxic materials, a major limitation is the low yield of hydrogen. Most of the work in this technique was done between 1998 and 2000 no new results based on this technique have been seen since. It does seem an intriguing way to capture the energy of ocean waves, with reaction chambers left to tumble in the ocean surf. 

A working example of a wave energy converter is the Pelamis, built by Pelamis Wave Power (formerly Ocean Power Delivery, Ltd.), www.pelamiswave.com. an Edinburgh technology company focused on ocean wave power generation.

Wave Power - The concept of capturing and converting the energy available in the motion of ocean waves to energy. 

It is important to note that the best choice of material may not be just that which is capable of the greatest energy density but may also consider economic considerations. The effect of economic factors is more critical in large-scale energy harvesting (such as ocean wave power, as will be discussed below). Koh et al. [6] use their nonlinear material model to show how under some operating conditions natural rubber can outperform 3 M VHB acrylic. While this analysis claims similar maximum energy density for the two materials (which may not be a valid assumption under real-world conditions), it does not even consider the much lower cost of natural rubber. 

SRI developed and demonstrated the use of dielectric elastomers for harvesting the energy of ocean waves. This work included two sea trials in which SRI deployed a complete energy harvesting system at sea. Figure 3.7 shows the system for the first sea trial conducted in Tampa Bay near St. Petersburg, Florida.

Other forms of mechanical energy include the motion of water or sound. It is easy to imagine the energy contained in the force of falling water or ocean waves crashing on the beach. Similarly, sound is nothing more than... 

In the next 20 years, hydrokinetic power drawn from the earth s oceans and rivers could account for more than 10% of the world s global electricity market (Wood, 2010). The renewable energy resources from ocean wave, tidal stream, ocean and river current and ocean thermal resources are expected to be the major growth area over the next decade (Marsh, 2009).
