Heavier the traffic, brighter the road. A model created by an engineering graduate of a city institute proposes to convert mechanical energy of vehicles passing over speed breakers into electrical energy that could illuminate street lights for about a kilometre.
“The highest point of the speed breaker would be made of rollers that would rotate as vehicles pass over it,” said Anand Kumar Pandey, pursuing MTech in electronics from Bansal Institute of Technology, adding, “The rollers would be connected to a set of three gear wheels (in descending order of diameter), which would be linked to a dynamo to convert mechanical energy into electrical energy.” As a result, the usual traffic movement will generate electric power enough to keep streetlights installed for up to almost 1 kilometre on for eight hours, he claimed. The model was put on display at the office of the UP Council of Science & Technology on the occasion of birth anniversary of former President APJ Abdul Kalam on Thursday.
According to Pandey, this innovative use of speed breakers may prove effective in areas of the city where more than 20,000 vehicles pass daily, such as Hazratganj and the Polytechnic crossing. “The model can work on rumble strips and also on single speed breakers and prove effective also in villages and rural areas,” he said, adding that cost incurred in implementing this innovative model would be around Rs 12 lakh. “I spent Rs 20,000 to develop this model,” said Pandey, a Sultanpur native, who completed B Tech in electronics and communication technology from Rajarshi Rananjay Singh Institute of Management and Technology, Amethi in 2013.
Delhi-based patent office (Intellectual Property Office) of the Government of India has acknowledged the idea and concept and issued a docket number (32363). If he gets a patent and his concept finds takers, the, innovation could be implemented in 2 to 3 years.
“I am also trying to make the model workable for roads on both sides of the divider,” said Pandey, adding that electricity generated can be stored in chargeable batteries, which would then be channelized towards turning on the streetlights.
Another innovation in the model is light-sensitive lamps. “The moment the lamp senses natural light up to a certain level of visibility, it would be switched off, saving power,” said the innovator, who had also presented the idea to the state government. He was also of the view that the concept of piezoelectricity (power generated from pressure) can later be harnessed by the mechanised speed breakers.
