speed breakers are source of power generation |
|---|

Man in his lifetime, uses energy in one form or the other. Energy demand continues to grow, year after year. In the present scenario power becomes major need for human life. But the extensive usage of energy has resulted in an energy crisis, and there is a need to develop methods of optimal utilization, which will not only ease the crisis but also preserve the environment from the negative impacts of global climate change. Energy conservation is the cheapest new source of energy. It is an attractive technology for optimal use of available sources. This research shows the possibility of tapping the wasted energy in the road speed breaker. The wasted energy can be converted to the electrical energy by roller mechanism through several energy conversion processes. In this research, the obtained electrical energy is in KW range which is sufficient to lighten the street lights and traffic signal. As the number of vehicle is increasing day by day, the designed system will be effective to solve the power crisis of Bangladesh to some extent.
About Power Hump
Power Hump is a dome shaped speed breaker having some special arrangement which helps in generating electricity from high speed moving vehicles. The main concept of the project is that if we convert some of the kinetic energy of the vehicles into rotational motion, then we can generate a substantial amount of electricity. Review of Literature According to Rhodri Phillips (2009) of the Automobile Environment Network Green ?speed bumps that will generate electricity as cars drive over them are to be introduced on Britain?s roads.? Peter Hughes, the designer behind the idea said ?They are speed bumps, but they are not like conventional speed bumps. They don?t damage your car or waste petrol when you drive over them – and they have the added advantage that they produce energy free of charge.? A spokesman for Ealing council in west London confirmed that 𧵎,000 of funding had been secured for the scheme of power humps. A K Das, a professor at IIT's design department says "A vehicle weighing 1,000 kg going up a height of 10 cm on such a rumble strip produces approximately 0.98 kilowatt power. So one such speed-breaker on a busy highway, where about 100 vehicles pass every minute, about one kilo watt of electricity can be produced every single minute. An amateur innovator in Guwahati Kanak Gogoi (2007),has come up with his latest invention, which promises to convert the kinetic energy generated by speeding vehicles into electrical energy, a ''mechanical ramble stripe'' or ''mechanical speed breaker In the above connection, another youngstre R.C.Prince Leo (2010) has concentrated the focus on the very new and innovative concept i.e. generating electricity from speed breaker. Critical appraisal of literature Till date no reviewed and published documents are available in the literature. However, some conceptual ideas regarding this technology are collected from various sources, such as, internet and editions of news papers. This being a novel as well as upcoming research area, the design, development and performance evaluation of the said technology motivated us for this project work. objective The above challenges inspired us a lot and made us to think about for generating mechanism to save the wasted power from automobiles to generate electricity In specific terms, the objectives of the project work are as follows: 1. To select an alternate source for generation of electricity for lightening the streets 2. To design, develop and performance evaluation of the mechanical setup of the project work. Theory Power hump is a dome like device likely to be speed breaker. Whenever the vehicle is allowed to pass over the dome it gets pressed downwards then the springs are attached to the dome are compressed and the rack which is attached to the bottom of the dome moves downward in reciprocating motion. Since the rack has teeth connected to gears, there exists conversion of reciprocating motion of rack into rotary motion of gears but the two gears rotate in opposite direction. A flywheel is mounted on the shaft whose function is to regulate the fluctuation in the energy and to make the energy uniform. So that the shafts will rotate with certain rpm these shafts are connected through a belt drive to the dynamos, which converts the mechanical energy into electrical energy. Detail design of equipments Design of spring chromium vanadium alloy steel is used as spring material Maximum shear stress induced: Deflection of spring: Free length of spring: d = 7.67mm n = 25 Pitch of the coil=14.97mm L = 389.32mm |

A very sustainable and eco friendly way to save energy.
This will indeed help our planet.
Thanks for sharing!

I had read about it and even done a project by considering & analysing underground parking area of a busy mall where so many cars come and go and if such a power pump is installed there , we can generate enough electricity to power at least the parking area. Thanks for sharing ,Ahtisham .

An underlined report, for a change, seems good, Ahtisham.
Seems quite an innovative idea. In some countries many similar studies have been conducted and research is on going.
This is indeed a sustainable, green idea.
If streets may be lighted likewise it'll save lot of energy
