Buying things on the Internet, such as books, air tickets and groceries, is becoming more and more popular. Do the advantages of shopping in this way outweigh the disadvantages?

There is a lot to know about wave energy machines, the setup, the placement of the machines and their working. As far as the setup part is concernced they can be installed near a high tidal area or a low tidal area depending on the requirements and ideal conditions of the place. The machines installed within low tidal area gives less output as compared to the ones installed on a higher tidal area and their costs are also changes according to that with the high tidal ones having more installation costs. A typical wave energy machine works with the input flow of a wave that increases the water levels in the machine, the water flow in turn forces the drag of airflow into the vents causing the turbine to move. Now as the physical motion is created due to the movement of turbine electricity is generated. This is the same concept that is used for wind mills. The speed of the turbine depends on the air pressure created by the input and output airflow which is again directly proportional to the speed of the waves. A major factor to consider here is that not all machines can handle the same type of tidal waves hence there are different types of tidal machines majorly for high tide and low tide.
