Tide Energy

As we continue to look for alternative energy sources, the ocean and the energy deride from the movement of water, in the form of tide, can generate a lot of energy at our disposal.  The key is how to harness that energy. Massive amount of energy is used everyday to move large size of water.  Researchers believe that there are two basic ways to convert tides into power. The first involves converting the power of the horizontal movement of the water into electricity. The second involves producing energy from the rise and drop of the ocean’s water levels. Converting moving water has been something that we have been during for a long time.   Basically, energy is produce by passing moving water through turbines that spin and create electricity.  This is what power all water dams.  Some what is holding us back?  The problem is that ocean water moves a lot slower than water that is funnel narrower and narrower down a lake.  The other problem is that the energy in the ocean is spread out and not confided in a small area.  So we will have to figure out a way to funnel that energy into tubes that gradually increase its velocity before it reach turbines that need to spin to create energy.
One theory is to let water come in when the tide is rising and trap it when the tides goes out. The trap water is then diverted into pipes with turbines and you essentially have hydroelectric power.  Researcher will have to look at this possibility and figure out other obstacles like how to deal with salt water which tends to erode equipment and infrastructure.

Large wave riding

According to eye witnesses, the largest wave ever ridden by a human being was accomplished last week off the coast of Nazare, a small fishing town seventy miles north of Lisbon, Portugal.  The wave measured about 90 feet. According to Guiness World Record, the largest wave ridden prior to this was seventy-seven foot in Cortes Bank in 2008, off the coast of California.
