Energy From Nothing

Once somewhere in the 20th century a young scientist thought that why not connect a motor output to a generator input and similarly connect that generator output into that of the motors input , this would create a loop of energy that would not end ever and energy can be created from nothing. Wouldn't it be amazing no need for fule to run any device?This idea was considered a revolutionary vision and a lot of devices were made on this modle but non worked perfectly and it failed. From the research and our increased knowledge of science we know that energy cannot be created nor be destroyed but can only be transformed from one form to another and the machine similar that described above which gives work without taking heat or vice versa is a hypothetical device that violates first law of thermodynamics i.e. conservation of energy and is termed as Perpetual Motion Machine of 1st Kind or simply PMM1. It is nothing but an imaginary machine which is just theoretical but not practical and all working devices are made as close to the performance of PMM1.
Similarly by our knowledge of science and engineering there cannot be any device that produces work(energy)  without rejecting heat only with one fixed temperature, which was formulated by Great Scientist Rudolf Clausius, and the device that violate this is termed as Perpetual Motion Machine of 2nd Kind or PMM2, and if it was not true we could extract energy from our surrounding atmosphere and for the world there should be no need of power generation, but this is not possible so we need two temperatures to get energy generation.
This is just the beginning of a blog that is dedicated to engineering wonders and the beautiful laws which governs these engineering devices. This is the perfect platform to explore the various engineering Connectios made by the humans, at last the biggest engineer is the nature which has created us and if we are lucky we will surely learn something from the nature and create wonders.
