 Electro-kinetic road ramp

The electro-kinetic road is a method of generating electricity by harnessing the kinetic energy of automobles that drive over the typical street traffic.

In June 2009, one of the devices was installed in the car park at a Sainsbury's supermarket in Gloucester, United Kingdom, where it provides enough electricity to run all of the store's cash registers. The ramp was invented by Peter Hughes, an electrical and mechanical engineer who is employed by Highway Energy Systems Ltd. The company says that under normal traffic conditions, the apparatus will produce 30 kW of electricity. Other proposed applications for the road ramps include powering street and traffic lights, heating roads in the winter to prevent ice from forming, and ventilating tunnels to reduce pollution.

The idea was dismissed as Talk of 'kinetic energy plates' is a total waste of energy in the Guardian by David MacKay, the professor of natural philosophy in the department of Physicsat the University of Cambridge. MacKay wrote, "The savings from parking at the green car park thus amount to one four-thousandth of the energy used by the trip to the supermarket."

Power Street Generation is a system able to recover

part of kinetic energy dissipated by moving vehicles,

during acceleration.

The innovative method for energy recovery is the strength of Power Street Generation. Its operation is based on patented mechanisms and a system 100% made in Italy. Currently patented EPO N.2527652, Power Street Generation  makes the elements that make up its technology its the strengths.


The only visible part of the entire device, a moving road paving, able to support the weight of any vehicle ensuring a safe transit, has the task of capturing the energy generated by the wheels of the cars and then transmit it to the conversion system by the axes below.


The axes are connected to a track system mounted on linkages that have the task of receiving and transmitting the kinetic motion making a link between the device and the energy converter.


The last part of the device, has the task of converting the kinetic energy carried by the kinematic energy into electrical energy. It ‘just the energy converter. This final section will then be connected to the power grid to directly enter the energy generated and make it immediately available for use.


The device is placed inside a cavity of the road surface. The external surface is visible and passable by vehicles. Its steel structure, allows the safe passage of all vehicles on the roads, from motorcycles to tractor-trailers. The modular structure helps to ensure that any maintenance can be carried out quickly. Power Street Generation has as its target market every country of the world where there are urban and extra urban centers and points with high traffic density. So anywhere! And wants to talk about clean energy generation with Private Companies, City count and supporters of “Smart City” project, owners or managers of roads and highways, electric energy companies and brokers.

California-based AEST has developed a road plate technology that create electricity when pressure is applied to it, such as a car driving over it.  A system of 20 of its plates can generate 10,000 to 12,000 kWh per day and costs approximately $2.5M USD to deploy.  With power in the U.S. at over $0.10/kWh, that's a a savings of over $1,000 a day and over $300,000 per year.  At that rate the system will repay itself in just over 6 years.


Dragon Power Station (SCR)…

SCR generates and distributes renewable, off-grid clean electricity from the capture and harnessing of weight and speed – untapped kinetic energy – of heavy vehicles at controlled roadways. SCR reduces current operational electric costs, stabilizing future power costs for its customers, while providing an alternative and less expensive renewable source of energy. Designed and manufactured for the amount of necessary power to be generated based on location, traffic flow and type of vehicles, SCR ideal locations include entrances and exits at port authorities, border crossings, truck/bus depots, weigh-stations, and toll-bridges, parking garages, military complexes and theme parks. Specific configurations, number of plates used and the size of the generator will be determined after an analysis of the customer’s location and load (energy) requirements. By examining traffic patterns and vehicle types AEST can produce units for maximum power generation per each specific location.

The concept behind AEST’s SCR is derived from an adaptation of an old means of generating electricity from rivers and streams. In those proven applications, a fluid (water) turns a turbine, which drives a generator. AEST’s innovative adaptation utilizes the movement of cars and trucks crossing over pressurized road plates that depress under the vehicle’s weight to generate electricity.

SCR consist of two major components:

(1) Road Plates

SCR is designed for installation in areas where vehicles come to a full stop, or move less than 30 miles per hour. Vehicles simply drive over road plates placed in the road. Each SCR road plate houses individual steps. Each step captures the weight of the vehicle and initiates a series of pumping actions that, via hydraulic linkage, turn a generator, ultimately producing electricity. AEST’s power generation station can be deployed as a single unit or in a constellation of multiple units, as needed.

(2) Power House

SCR Power House is a closed and secure area beside a roadway normally within 100-feet of the road plates. This powerhouse unit houses the accumulator, generator and other electrical equipment. SCR technology also incorporates the use of solar power panels that reside on top of the power house…See illustration and photo below.

Creating Kinetic Energy from Moving Vehicles


Cars have always been energy consumers. The idea that they can also be a source of energy may not go well with many. However, it has always been theoretically possible because energy consumed by a car is actually converted into other form. Most of them are also wasted.

We have not been able to capture this energy in the absence of a proper mechanism. But researchers have now developed methods that can actually make your car an energy producer. Such technologies may kick start an era of self-powering cars in near future. The electricity so produced could also be used for powering traffic signals, street lights etc.

Need for change

Conventional fuels have two disadvantages. First, they release green house gases and aid the process of climate change. Second, their prices are continuously touching new highs. This causes serious dent into a household’s economy. All these call for a switch over to renewable sources of power to ensure a sustainable future.

What’s next?

1.  Motion Power Kinetic system generates electricity from moving vehicles

What’s new?

Developed by New Energy Technologies Inc., MotionPower system can capture the kinetic energy produced by vehicles during their movement and convert it into usable electricity. The company aims to install the system at various high traffic locations. It can be customized according to on site conditions for maximum output. According to New Energy, the system can be easily installed, manufactured and is resistant to damages caused by vehicles, weather and road debris.

What difference it will make?

It has been anticipating that the installation of the new system would allow to replace the conventional electricity connections for powering roadway signs, street lights etc. with a clean and green source of energy. The extra eletricity so produced could also be stored and supplied to households.

2. Regenerative suspension system

Regenerative suspension system generates renewable electricity from bumps

What’s new?

Regenerative suspension system can capture the vibrations produced during the movement of a vehicle and convert into usable electricity. Developed by the State University of New York, this new technology is in the form of regenerating shock absorber with two tube like components. The smaller magnetic tube slides inside a larger hollow coil tube made of copper. The coil tube moves relative to the magnetic tube because of the vibrations caused by suspension system of the car. The movement of copper coil in the magnetic field produces electricity which can be further used for recharging car’s batteries.

What difference it will make?

The new system will reduce the dependence of car owners on conventional fuels for recharging the batteries. This will make driving cheaper and an environment friendly activity in the long run.
