The given diagrams depict the layout of a wave-energy machine and its emplacement.

Overall this device has two chambers, a turbine and a electric generator which are used to create electricity and the installation costs depend on the size of the wave.

The lower apartment has place for water inlet in opposite to the direction of the stream and an air flow from chamber one also put the pressure on the stream, as the water level increases and decrease it results in the flow of air from lower box to upper box. Then, the air transferred help the turbine to move.

The upper part of the machine has 2 incoming and two outgoing gates for air. Due to the air pressure the turbine starts moving the thus it starts generation power to electric generator which then help to generate electricity. To install stream-energy device, first wave size should be considered as it requires more money to setup machine in large wave area because depth is more here and therefore requires a larger base before machine installation . Subsequently, larger waves produces more electricity than small waves.

Internet is now considered as a basic neccessity for every human being and the trend of shopping has seen a drastically change after the easy availability of internet as well as the flourishment of E-Com business. People have startred purchasing goods from online platform as they provide range of products in addtion to big discounts. I opine that advantages of online purchase outwrigh the disadvantages.

On the one hand, buying products from online platforms gives us a variety of products especially in groceries, which we may found unavilable in our local market. For example, one of my friend, who is living in new delhi, want to relish the world famous panchi petha of Agra. So i ordered this through flipkart and got delivered in 3 business days. Moreover, shopping through internet can get us bumper discounts on air tickets and books as many ecom platforms celebrate festivals by providing heavy discount and great deals like big billion day. Last year, my brother purchased a new phone during flipkart summer festival offer and got discount of fifteen thousands on purchase of forty five thousands.

On the other hand, we cannot predict the quality and originality of the product when we shop on internet. Like, my mother purchased a puma trouser from amazon, but the product was first copy material and quality was soo bad as well as the size was also very small. Also, there are many fraudants are present who can easily make you fool by taking you money and not giving any servies or products .Like, a man purchased a motor bike through AutoBikers, but he got a toy bike from them.

In conclusion, online purchasing has both merits and demerits. However, it seems to me that shopping through internet is helful as it saves time and effort because its benefits outweigh its drawbacks on the whole.
