As part of a school project, I would like to make a machine similar to this video: https://www.youtube.com/watch?v=VtTZ855O5ds&t=107s, to convert the mechanical energy of the swell in electrical energy.However, with little knowledge of motorization etc, I would like to know what types of generators and / or DC motors would be most suitable for the system presented on the video.Thank you for your help.
