The heart of the product is a shower head that indicates the number of litres of used water, in real time, having fun.
Hydrao lights the shower with different colors according to the water used, to encourage you to limit the consumption without any other action.
At the same time staying simple and affordable, Hydrao is a shower head like any other and can be plugged easily in your bathroom.
In order to stay totally ecological, the product doesn't need any battery! The lighting of the LEDs and the electronic chipset are taking the power from the water flow to operate (micro hydroelectric mill).
Having watched at the movie "A thirsty world" from Yann Arthus-Bertrand, we decided to do something at our level and save tap water at our own home.
We are all knowing perfectly that it is much more efficient to reduce our ecological footprint by acting thanks to encouragement and education rather that coercion.
With Hydrao you will have fun, that's the ideal tool to teach the whole family, particularly young children, without any shouting...
One shower = 80 litres of water (for a 5 minutes shower, on average), 200g of produced CO2 (electric heating) or 2 kg of produced CO2 (gaz or fuel heating) and 0.50 € (0.25 € for water, 0.25 € for heating)
Above the "savings for the planet", the resulting cost (water and heating) at home should encourage you as well. A family of 4 people could save 250 € per year (and thus make your investment quickly profitable!)
(*) for an average cost of water and energy in France in 2014 and assuming that everybody is taking a daily shower, with a target of 55 litres instead of a usual 80 litres.
You can calculate your accurate potential savings corresponding to your case, here.
A version of the product is "connected" (bluetooth). An app allows you to take control with your smartphone.
As example, changing thresholds and colors is imaginable:
Record yours progress, your best score and your savings :
A patent is pending, the principle can be used by several other applications, particularly for hotels or public equipments
Hydra is a small island of the Egean sea. We made a trip overthere when we were students. We were amazed by the fact that water was very rare. Every day a water tanker is bringing water for hotels and tourists showers.
Gabriel DM., Hydrao project founder, with 4 daughter, he knows a lot about spending too much time in the bathroom at home !
Telecom engineer, he decided to offer his creatitivity, his skills in electronics and internet of things to sustainable development.
Didier, co-founder, responsible of an engineers team in ST Microelectronics, is taking in charge the manufacturing and sub-contractors.
Stéphane, responsible of the foundation "Défi sport" (Sport for disabled children and young adults), has specified the product and its improvements, particularly the new apps for iOS and Android.
Emmanuel, engineer responsible of system validation in ST Microelectronics, is the technical expert of the Hydrao project. He developped and validated the prototypes.
Now we have our first manufacturing prototype, our next step is the manufacturing of the product.
We decided to privilege the european industry with a french crowdfunding platform and a french company: Eolane.
Eolane is located in the Maurienne valley (Alps) and recruits localy mainly women (working with electronics).
Our project is "eco-friendly" and must stay "ethic" as well !
To stay affordable, it is needed to launch a minimum order of 300 showerheads.
We are considering, in the presented budget, a layout update or a mecanical issue to solve.
300 smart showerheads manufacturing cost: 9000 €
First Hydrao app development cost: 2000 €
Electronic or mecanical manufacturing file update: 3000 €
Crowdfunding platform (KKBB) et credit card cost: 1000 €
Total: 15000 €
Now, we need you ! If you make a donation, and that the total amount funded reaches 15000 € (if unfortunately, it is not the case, you will be totally refunded), we will keep you aware and we commit to provide the following rewards.
