  5. 34. Review of Methods for Energy Harvesting from a Vehicle Suspension System

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Jesper Eriksson; Shwana Piroti; [2016]
    Keywords : ;

    Abstract : With the increasing population the energy consumption has increased which makes the requirement for clean energy important, now more than ever. The transport sector is one of the biggest contributors to this consumption and should therefore be taken into consideration when looking for environmentally friendly solutions. READ MORE
