Tide power is a ecology efficient means of capaturing energy created as waters moves in the oceans currents and tides. Currently there are two methods to capture tide energy: (1) Kinetic energy, is energy created when water is moving in waters and oceans. In order to capture this energy one needs the use of turbines that produces energy when they spin. So for example, if you place turbines at areas where you have high speeds of water that move into rivers or bays, you can generate free energy. People have used this kind of energy for a long time. If you recall in Europe during the castle ages, and you have water wheels in the rivers that rotate to produce grain. China is another country that has harraness this power back in the Ming Dynasty. So the technology is not new. Its how efficient and cost effective we can produce the energy today that is causing us to take another peek at the opportunity.
In our constant quest to harness tide energy, researcher at the University of Wages have come up with the idea of manufacturing under water turbines that rotate as the water tides moves back and forth. The key is to find a way to position the turbine in the optimal position where the tide can rotate the turbines to generate free electricity. The other thing that researcher will have to figure out is how to position and hold the turbines in the center of the ocean. Most likely it will have to use concrete blocks that are dropped to the bottom of the sea which can then serve as the platform for the turbines.
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.
All good to great fishermen know that in order to catch fish, you have to study the tides. You need to study the tide charts. Its important to know when the tide is going to hit the areas of where you play to fish and how long that tide is going to stay in that area. Wind plays a key role in tide stands. Incoming tides pushed by winds blowing from offshore will be higher at the base point. A sustain wind of 5 hours or more blowing steady wind from offshore cause cause a high tide to rise.
I recommend that if you are fishing inshore waters during the winter time that you stay in the deep holes. The best prospect of catching fish is when there is moving water. The incoming tide alwasy offers the best odds to catch fish because the rising water covers new feeding areas for fish and push food that seats at the bottom of the water to the top. When the tide is not moving the fish will tend to sleep because there is nothing to bring the food.
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.
High tide is when the sea water reaches its greatest height within the tide cycle in its area. Low tide is when the sea water reaches its lowest height within the tide cycle. Normally there are two high tides and two low tides each day. This is the result of the relationship between the earth and the moon. The moon wants to pull itself closer to the earth. Water on the earth is the only thing that is not fixed so the moon is able to influence and effect water circulation in our oceans.
Spring tides occur during the full moon and the new moon. When the moon is full or new, the gravitational pull of the moon and sun are combined. During these times, the high tides are very high and the low tides are very low. This is known by many to be spring hide tide. Spring tides are especially strong tides. They do not occur only in the Spring and do not have anything with the Spring season. They generally occur when the earth, the sun, and the moon are in a line. The gravitational forces of the moon and sun both cause a greater effect on the tides on the earth’s oceans, lakes, and etc.
What is causing this is the questions that the citizens of British Colombia’s Lake Okanagan are asking each other. Are the ripples that you see in the photo caused by tides and waves in the lake hitting some rock formations underneath the lake? Or is there something else causing this. If you watch the video, you will notice that the ripples in the water suddenly stop. Could it be possible that the tide changed or the moon’s gravitational pulled stopped suddenedly? Many believe the cause of what you are seeing is from Canada’s version of the Loch Ness Monster. No the monster cannot be seen in the video but the wave moments are interesting and a subject for debate.
Two of the most obvious features of the ocean are waves and tides. Winds drive waves, which travel for long distances as a series of crests and troughs. While the gravitational pull of the moon is responsible for tides. All coastal areas experience a two low and high tide within a period of 24 hours. Because the moon is much closer to the Earth than the sun, it has more gravitational attraction. This effect creates a unique relationship between the two planets. Therefore when the moon is directly over a given point on the Earth’s surface, it exerts a powerful pull on the water there, which consequently rises above its normal level.
At the same time, the water covering the Earth that is most distant from the moon bulges outwards as a result of the centrifugal force of the revolving Earth. This is the same force that pulls a person away from the centre of a revolving merry go round. This Earth moon relationship revolves around a common centre, which is similar to the centre of a merry go round. A child close to the outer edge of a merry-go-round is pulled outwards more than one near the centre. Likewise, as the Earth revolves around the common centre of the Earth and moon system, the area furthest from the moon is subject to the greatest centrifugal force. As a result, the waters on that side swell outwards.
This means there are always two high-water areas on the Earth at any given time: the area under the moon and the area opposite the moon. Low tides exist in the areas between these high-tide bulges.
Low and high waters moves in a continuous cycle. High tides move with the moon as it revolves around the Earth. At most shores throughout the earth, two high tides and two low tides occur every lunar day, which is the time it takes for the moon to return to a point on the Earth. About twenty four hours and fifty minutes. Thus, a typical beach will alternate between high and low tides about every six hours. Some coasts, such as the shores along most of Antarctica and other secluded bodies of water, experience only one high tide and one low tide each lunar day. These varying results in the tide cycles occur because of several factors, including different topography and latitude.
