IELTS Summary Article (v) Energy-efficient engine turns waste hot water into electricity

Recently, Exergin, a company which focus to produce electricity from waste hot water in a wide range of applications, plans to run the first industrial trials of its technology. Exergyn also estimates the heat lost in waste hot water from several sectors such as cargo ships and big factories as equal as energy in Saudi Arabia's oil and gas output. They try to use new material called nitinol which has several usage such as medical equipments, sunglasses and NASA's transportation. They also argue that although a device only improves a less efficiency, but this is free energy we can get. Furthermore, company had spent their time to perfecting the design and the material. They also predict will expand to the geothermal market.

Dioba, your summary is lacking some information. Most notably, the name of the technology that Excergin developed. You neglected to mention the reason for the development of the technology and its other applications if any. Obviously this is a summary essay for a procedural report so a short description of the technology along with how it is executed should have been included in the summary. By the way, the technology cannot improve a "less efficiency" as all technology is developed in order to "improve efficiency" so I think you just made a mistake with your term usage in that instance. The essay speaks of other applications of the technology, but doesn't really indicate how the technology is ideally going to be used in the first place.

Basically, the essay takes bits and pieces of information from all over the report without taking care to actually indicate the importance of certain procedures, descriptions, and keywords. That has weakened the summary ability of this essay and has resulted in a less than stellar and non-informative essay. The reader cannot really understand what the purpose of your summary is because of the lack of proper information within the written text.
