In this presentation, we will talk about some interesting technologies that are arising in the 21st century to generate energy in non-orthodox ways. The first technology is the “in-pipe turbine”, an approach to generate energy from the water distribution systems of cities and towns. Instead of using pressure relief valves to reduce pressure in some cases, it’s possible to use this kind of turbine to generate a little amount of energy that can go back to the grid. In the Halifax Regional Municipality, there is a pilot project running. The second one is “wind energy from traffic”, an approach to generate energy from the movement of the air produced by the cars and trucks on highways and tunnels. Is a very interesting approach to squeeze energy from one of the most inefficient devices made by man: the car, because basically you are transforming some energy from fuels on electricity, or giving some electric energy back to the grid if you’re using an electric car. The third one, is the “wind-hydro turbine”, a technology that allows to store potential energy using a wind turbine when there is a surplus of generation capacity and use it when the wind doesn’t blow enough. This approach is not recent, but the way that is proposed now, and it’s already working, is revolutionary. The fourth one is really curious, and by the way really inefficient, the “wind tree”, but the concept is interesting and deserves to be mentioned. All those approaches are very interesting, some of them are more efficient than others, some have future some haven’t but all of them shows that not everything has been done in power generation.
