AEOLUS allows you to charge the batteries of your electronic devices with a wind turbine.

For this project, we have decided to tackle a problem we all face nowadays : being able to charge our electronic devices (smartphones, laptops, etc.).

One of the constraints we imposed on ourselves at the beginning of the project was to carry it out within the current ecological dynamic by offering a clean
alternative to produce energy. That is how we made the choice to use the knowledge we acquired during previous projects to combine power electronics and wind energy in order to create a domestic wind turbine names AEOLUS.

The idea behind the AEOLUS project is quite simple: it is a small vertical axis wind turbine (so its design differs from traditional wind turbines that we often see) for individuals which allows, thanks to the energy supplied by the wind, to produce electricity that will be then used to charge the batteries of our electronic devices. The prototype has indeed two types of output: a USB output and a classic European outlet (220 V). This way, the user will be able to directly plug his laptop charger or his USB phone cable on the system.

The obvious benefit of wind energy is that it is of infinite supply. However its biggest disadvantage is that it is inconstant and the end user can’t predict exactly its behavior and its intensity. This is why it seemed mandatory to look for a context where this project could be of real utility.

It seemed obvious that in the areas where the electric network is developed and fully working, peple using smartphones for instance wouldn’t need such a system. On the contrary, in some places like underdeveloped or developing countries or even desert areas, the electric network can be failing or nonexistent. AEOLUS is an interesting alternative to people living in such areas or visiting them (for instance researchers or people working for NGOs) to use their electronic devices while being respectful of the environment.

Carrying out AEOLUS in such a context allowed us to find a way to give it value and to make it accessible to the people we’re targeting. Indeed we chose to add value to this project by making it in the Open Innovation framework by making the different techniques, materials and components we used to make the system including the subsystems we made thanks to the simulation software SolidWorks. The making of this project was done trying to minimize the production costs even if it sometimes meant to reduce performance. All this in order to make it accessible to most people. The relevance of our project was confirmed to us by a Togolese engineer working to spread such projects in his country who told us that some people walk up to 3km in order to be able to charge their cellphones.

The future of AEOLUS would be to spread the system to people who need it, most likely via NGOs and to keep working on a way to minimize its cost while optimizing its performances.
