Bumpy Energy

Tuesday 3rd December 2013

Piezoelectric materials produce electricity from pressure or stress - as we have seen before it could be steps as people walk, or the weight of vehicles as they travel over the material. Sounds good but it is costly to implement.

Hence it is good news that a Mexican entrepreneur Héctor Ricardo Macías Hernández has shown ingenuity in creating his own system that generates electricity from traffic flow on the roads.

The system uses small polymer tire-like ramps embedded into the road, rising about 2 inches (5cm) above the road. Air is forced through bellows attached to the underside of the ramp, and through a hose to be compressed in a storage tank. The stored compressed air is ultimately fed into a turbine, generating electricity.

“This is a technology that provides sustainable energy and could be implemented at low prices, since it’s a complement of already existing infrastructure: the concrete of streets and avenues”, Hernández said.

He added: “Accumulation of electric energy is proportional to the flow of cars over a determinate spot; however, in places with low vehicular flow, several ramp-steps could be placed to multiply the impact of every individual vehicle.”

The system could also be adapted for pedestrians in areas such as subways or metro rail stations.
