REPLACING HINGED DOORS WITH REVOLVING DOORS TO PRODUCE ELECTRICITY

REPLACING HINGED DOORS WITH REVOLVING DOORS TO PRODUCE ELECTRICITY

Albert Camus says that great works are often born on a street corner or a restaurants revolving door. But now a days technical minds say that a little modification in a revolving door can do a great job. Hinged doors can be replaced by energy efficient revolving doors that not only add glamor to the buildings of cinema houses, restaurants, shopping malls and stadiums etc but is another contribution for the greener world. According to the calculations done by the students of University of Engineering and Technology, Lahore, Pakistan, if 10,000 people pass per day with each each passing period to be 2 seconds then approximately 600 W.h of energy can be produced in a day and 222 kW.hr in a year which is equivalent to the  energy produced from burning of 111 kg of coal. Hence installation of this mechanism can prevent 0.33 tones of CO2 from polluting the environment.
