More than wind turbines to some extent. Tidal electric plants have limited impact on environment than any other types of elctric plants. They upto 80% efficient making it almost comparable to solar energy. The benefits of tidal plants are pretty amazing. As it is very easy to predict tides so its utilization rate is much higher. The only major cost in making this is initial and only when slits are needed to be made behind barrages. Tidal energy is renewable and the electricity its able to produce is high quality.
And another key aspect of tidal plants are they emit no greenhouse gasses making it on of the most safer ones to our environment. And if the turbines are created vetically than the cost gets reduced.
Also the turbines are very efficient and inexpensive to manage. But the real dillema is you cant create a plant every where.. only particular places are safe to build one.
Also tidal surges gets reduced making the nearby lands safe from them. But because of no channeling technique being available the dirt that comes with tides gets condensed and fills up the neary lands.
Overall If my opinion is they are one of the solutions to counteract greenhouse effect. And only that reason is enough for us to shift our energy producing methods from nuclear plants to renewable plants such as wind, solar or tidal turbines..
This is the ship that carries almost all records in its time: the largest (270 meters long, 30 meters wide and 54 meters high, calculated from the keel to the top of the smokestacks), the heaviest (44,000 tons) and the most luxurious (built with high-quality materials that cost US $ 400 million based on 1997 exchange rates). This is the RMS Titanic, which is predicted to be the first choice in transatlantic voyages during the time when the world of new flights climbed into the first months of its birth.
RMS Titanic is at the same time the culmination of human achievement in engineering engineering. He consumed 600 tons of coal per day which was burned in 159 stoves to boil water in 29 boilers into high pressure steam. The steam is then injected into two four-cylinder steam engines and an additional steam turbine with a total power of 34.3 megawatts of thermal or equivalent to the energy needs of a small city today. This made it able to skyrocket at a top speed of 41 km / h. Steam that has been used can still be used to drive generators that supply electricity to all directions. So that RMS Titanic could be illuminated by electric lights and equipped with Marconi wireless radio communication system, another luxury that ships did not have at that time. Even more remarkable, this ship consists of 16 separate compartments that each compartment can be isolated with a waterproof door. So if there was the worst situation, namely a collision between a ship or a ship hit something, the RMS Titanic would remain afloat even though the four compartments had been flooded with sea water. This is what raises the belief that the RMS Titanic will not be able to sink.
But in fact the RMS Titanic actually sank quickly in the morning of April 15, 1912 (British time) while on its maiden voyage from Southampton (England) to New York (USA). RMS Titanic sank no more than three hours after he touched a large iceberg in the northern Atlantic Ocean. The collapse of the evacuation process left 1,517 people dead from a total of 2,227 people inside. Of these, only 700 bodies were found floating on the freezing surface of the Atlantic Ocean. The rest were dragged along with shipwrecks to a depth of 3.7 km.
Why can the RMS Titanic intersect with the iceberg? The latest analysis shows that there are a number of combinations of astronomical and meteorological factors that are likely to contribute to this tragedy.
The first factor, the RMS Titanic sailed at the wrong time. It was common knowledge at that time that the shipping channel that would be crossed by the RMS Titanic intersected with the movement of the icebergs from the north. The icebergs came from fragmented Greenland glaciers as they entered the sea and then drifted south by the cold Labrador currents. 90% of these icebergs melt while still around Greenland. But the rest, especially the large ones can survive to drift into the Atlantic Ocean, in the amount of 150 to 300 icebergs per year. What Captain Edward Smith and other RMS Titanic officials did not realize, 1912 was an unusual year. So that during the month of April 1912 the number of icebergs drifting to the south side of latitude 48 LU reached 395 pieces. This population is almost four times higher than the average number of icebergs in April during the period 1901-1910. So that the northern Atlantic Ocean is full of ice compared to its normal conditions. The record for the number of icebergs in April 1912 was unmatched until six decades later, precisely in April 1970, when the number of icebergs reached 501.
