7Traffic vibration on bridge generates electric power

The Metropolitan Expressway Co., a company managing the construction, renovation, maintenance, and administration of expressways in and around Tokyo, has announced a project to generate electricity by converting energy created by the vibration resulting from automobiles driving on the Shuto (Metropolitan) Expressway. This is a large scale application of something we already knew about at human scale. It really looks like someone read our suggestion for its application.

9A kinetic energy generator ... what uses can you come up with?

The idea of capturing the energy of vibrations and storing it is not new, but here is another attempt at the idea, courtesy of Gizmag. Dr Steve Beeby and his team at the University of Southampton have created this version of the kinetic energy generator. The last time we discussed this idea, it was mentioned that perhaps a device like this could be used on a vehicle; it would take many of them to generate any meaningful electrical power. This version has many possible uses, some of them cited in
