Recently, a super-elastic collision of large-scale plasmoids i.e. solar coronal mass ejections (CMEs) has been observed and further supported by numerical simulations. However, the energy gain by the system in the collision process is not clear. In-fact during plasmoids collision process, the energy exchange mechanism is still a chronic issue. Here, we present conclusive in situ evidence of sunward torsional Alfven waves in the magnetic cloud after the super-elastic collision of the largest plasmoids in the heliosphere. We conclude that magnetic reconnection and Alfven waves are the possible energy exchange mechanism during plasmoids interaction.
