Human nil 1Running Head : HUMAN ENERGYHuman Energy RecoveryNameCollegeProfessorSubjectHuman Energy 2IntroductionSince the discovery of electricity , many inventions and theories were developed and have been create in to put electrical phenomena to practical hold . with the course of years , man has learned to harness the forces of record and convert them into useful forms of muscle . Examples of such ingenuity ar the hydroelectric mogul plants which uses the power of falling water the geothermal plants , which harnesses the energy in the Earth s interior the wind move and wind farms , which since of old have been in use point before electrical phenomena was discovered . Recent advancements in the handle of science and technology has made it possible for us earn energy in many other different shipway , from huge suns to infintesimal atomsDue to its efficiency and portability , electricity is the method of energy transmission system . It is readily convertible to other forms of energy , and with minimal energy losses . In the past , approximately electrical appliances in use were large devices . Only a few send away be carried and used by man in perfunctory activities , and most of them powered by batteries . Only lately we foundation see the development of smaller devices , and with the advent of nanotechnology , the creation of more portable devices has been greatly accelerated . However , since the invention of the change current , most of the electrical energy we can use now be produced in power plants , making the credit of portable devices to external or outlet power much impractical . Batteries , which have been present for some time , ar portable , but not cost-effective and often short-lived The need arises for more portable and lasting sources of energy . many another(prenominal) researches are already making progress in achieving this become , and one of which is the challenge of converting serviceman energy as a readily available source of electricityWith the aim of converting human kinesis and heating to usable forms of energy , many technologies and phenomena are being considered .

Among the most promising springboardsHuman Energy 3are piezoelectricity , thermoelectric effect , and electromagnetic induction . Piezoelectricity (electricity produced by mechnanical pressure from certain crystals ) and electromagnetic induction (electricity produced from a rotating magnetic field ) can be applied in to harness wasted energy from human motion , while thermoelectricity (electricity produced from difference in heat from cardinal metals ) for drawing energy from body heat (Wordnet , 2008 . These could lead to more efficient miniature devices such as watches , mobile phones and music players , and a considerable reduction in power utilisation , in personal , commercial , national or flat military activitiesHuman Energy 4ConclusionThe world s demand for more portable and efficient technologies has lead researchers and scientists to look for more portable sources of power to sustain these technologies . Several methods are under research , among them are the miniature dynamos , piezoelectric devices and thermoelectric devices . Dynamos provide the greatest descend of power among the three . However due to its heavy cargo caused by the magnet and...If you want to get a full(a) essay, order it on our website: Ordercustompaper.com
