Patent number: 9834892Abstract: The pneumatic roadway energy recovery system generates power from the weight of vehicles, pedestrians and the like traveling on a roadway surface. The pneumatic roadway energy recovery system includes a plurality of pneumatic pumps in fluid communication with one another and that are arrayed beneath a roadway surface. The pneumatic pumps are in fluid communication with a storage tank. The vehicles, pedestrians and the like traveling on the roadway surface compress the plurality of pneumatic pumps as they pass over the pumps, generating pressurized air, which is received by and stored in the storage tank. Preferably, a turbine, such as a Pelton wheel or the like, is in fluid communication with the storage tank. Selective release of the pressurized air in the storage tank drives the turbine, which, in turn, is connected to an electrical generator for generating usable electrical power.Type: GrantFiled: November 2, 2015Date of Patent: December 5, 2017Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventor: Ashraf Mohamed Samir Farahat
