Pocket energy

A new portable clean energy solution

Similar projects worth following
Pocket Energy is a project to make a new solution for clean portable energy. We are trying to make a device that recycles waste energy produced by our bodies into usable electrical energy.

Pocket energy project have for goal to reload your smartphone with clean energy. It will take the human energy which is create when we walk and convert it to electric energy. For that we will put a magnet in a solenoid the movement which will be create will create AC energy. We use a rectifier bridge for convert in DC energy. This system will reload the battery which will be connected to you smartphone for reload it. This project is create to have more clean energy.

Thanks to that you will can reload your phone while walking.

On the 26/05 we will demonstrate how does that work with someone who will walk and reload his phone.

    finally, the project wasn’t a success but with more components, time and knowledge, it could be feasible. The most important step to keep is, make a solenoid with copper, put a magnet in the middle and create a movement. Create a link between the solenoid and rectifier bridge with Ac and same with DC between rectifier bridge and batterie.We would like to say thank you to the CRI to give us a chance to make a project in English.

    we found a solution for the magnet, we decided to stick springs on the magnet. No problem with magnetism and it will rebound off the two sides. Today, we’re watching for the rectifier bridge but before doing it, we need to know what current will arrive from the solenoid, we need to check It. We took a multimeter and we watched the current in the solenoid.1.5 mA was measured after few movement. To be large, we decide to take 1A to the rectifier bridge

    we’re finishing the design of the box but we have to make some adjustments as the design was too small because of a problem when we used; the batteries and solenoid couldn’t fit in the box. When the box was good, we tried to find a solution for the link because the battery can’t be linked directly to the rectifier bridge. Battery doesn’t like when it’s hot so we want to sold a conductor wire between the spring of battery and rectifier bridge.

    It was complicate to print the box in 3D because it takes too much time and someone of the CRI proposed to take some wood, to design it on It we will not be as specific as a 3D print but, easier to use it, make it and it’s faster. We designed a box for the solenoid and a box for the battery. For reasons of space, we decide to keep only 2 battery instead of 5. We were looking for a good material but the simplest was the wood. Easy to work with and to cut.

    A part of the stuff is arriving so we’re trying to install the copper in solenoid. We’re working on a small size to keep it on the arm, but it need to be a bit powerful to have what’s necessary to recharge a cellphone. We’re beginning the design of the box . But technical question is on the table: how to build the box? In first time, we began to design it on Solidworks, it enabled us to have all the good dimensions and we made different trials.

    Our list of the necessary stuff is almost complete; we’re watching for the rectifier bridge if we want to make it or buy it. But our engineering minds said to do it so we’re asking for diodes to make it. In a second time, we’re designing the box for the solenoid and the magnet. The challenge is to have a good spring for the magnet, it will rebound off two sides of the box and it needs to not be magnetic.

    after many concertations, we want to make a prototype that we can put on the arm. But it can be put to another place. The magnet needs to move a lot and if we put it on the arm, it will move like we want when we’re walking (lot of people are moving every day, at least to go to the workplace) . If we’re walking 20 minutes at 5km/h , it’s more than 2000 movements for the magnet in the solenoid.

    To make energy, we’re using a magnet that is moving inside a solenoid to make energy, AC will arrive in a rectifier bridge and this one will convert in DC. This is directly going in 5 batteries to keep energy. If we want to recharge the smartphone, it is very easy, just connect the cellphone with the link and wait!

    First, we were searching how to recharge a smartphone without plugging it. This choice was made ecause cellphones are everywhere and there are 1.4 billons worldwide and it uses too much energy. Because every day, we are moving, we can maybe find a solution to make energy when we’re walking, with the movement of our body. Pocket energy is created!

    after a brainstorming, too many ideas were said but not a real project. We watched some videos on the internet to find inspiration. We thought about a battery recharged by a crank but it already exists. Interesting day but no real project was found.
