Rotor, low-cost DIY solution for millions of people to get energy from water



Rotor, solución DIY de bajo coste para que millones de personas obtengan energía del agua


With more than 1.1 billion people in the world without access to electricity, any proposal to reverse the trend adds up. And that is what is proposed by a team of German experts that has come up with a low-cost system that could provide energy to at least a quarter of that population. Specifically, the one that lives in the vicinity of a stream of water in which to install Rotor.



Behind that name a small portable and low-cost portable power generator is hidden through Mobile Hydro by artist Markus Heeinsdorff and by Environmental engineer Andreas Zeiselmair. The experience accumulated in their trips to places like Ecuador or Cameroon (Africa, by the way, concentrates more than 50% of the world’s population that lives outside the network) led them to think and rethink to shape a system capable of covering those needs


Sustainable for the environment and for the pocket with DIY options ( Do it Yourself or do it yourself), as well as reliable and capable of delivering energy both day and night. They are some of the master lines of this invention. As seen in the images, the simplicity of its materials is one of the keys to making it affordable (and thus useful) for the populations it intends to benefit in Africa, Asia and Latin America.



A tire, steel (sheet and tube) and a generator are the key parts of this solution to obtain energy from the flow of water in rivers, streams or any other stream. “It is made of materials available worldwide” , say the creators. In the absence of them, recycled materials and a little ingenuity to combine them are also worthwhile for anyone to shape this mechanism.



And this German team has not only designed the proposal and hopes to launch it in the form of a prefabricated kit. In parallel, it is committed to promoting a community that favors the arrival of electricity to areas that do not yet have access to it. Therefore, the promoters of this idea are committed to sharing it on the network so that those interested can manufacture their own solution . “It uses low-cost technology and can be manufactured by virtually anyone in a simple way” , they say about this alternative to convert the energy generated by the movement of water into electricity.



For this, simplicity is replicated in the operation of the system. Composed of a hydraulic wheel (the tire), a vertical axle and three blades, Rotor’s movement with the flow of water makes it act as an electric turbine that provides permanent energy. This is simply because the water does not stop flowing because the night falls or because the day dawns cloudy.



With that reliability, the proposal can reach a capacity of between 100 and 300 W . This would achieve, not only that the light reached the homes, but that they could refrigerate food or medicines, among others of the many possibilities that open electric power. Therefore, Heeinsdorff is confident that Rotor, or the instructions to manufacture it, will fit and favor the replacement of diesel generators or kerosene lamps that are used by communities that still live outside the network. By the way, one third of those that have stopped doing so in recent years are now supplied with renewables, especially with geothermal and hydraulic, according to the 2017 Access to Energy report of the International Organization of Energy, so the solution can go the right way.
