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.
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.
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.
