Road Energy Rams ( RER )



Is an Irish  invention that generates Co2 - free Electricity

Climate change is one of the greatest threats to our grandchildren and to your children’s future.

What is RER?

     An RER system converts the weight of traffic driving over the hydraulic system into Co2 free electricity

RER’s can be sited at the entrance and exits of; Car Parks, Shopping Centres, Transport Hubs,

Golf Clubs, Hotels etc.



RER’s can be used as traffic calming on approach roads to towns and villages, and as speed ramps in urban areas.

All the hydraulic components are contained in the steel modules
which can be bolted to, or sunk into the roadway.

As the cost of electricity and carbon tax rises, an RER system depending on traffic, could have a pay-back-time of less than Four years.
