Which problem are you trying to solve?

Access to energy for schoolchildren in rural areas and the preservation of the nature of electronic waste.

How are you going to solve the problem?

By recycling the li-ion batteries of laptop users to make them energy sources, manufactures lamps for domestic use, for
many schoolboy.

What is the impact of your project?

Batteries are indeed one of the sources of accumulation in the environment of certain heavy metals and other chemicals
that can lead to soil contamination and water pollution.
Reduce the amount of bat

How can the project be manufactured in the OpenLab?

To realize the prototypes we will need the
- the 3D printer or a laser cutting if it is wood or plexiglass,
and -electronics
-solar panel for recharger battery
-Lithium Charger Shield

Describe your project in detail

According to estimates by the World Bank and the United Nations (UN), of the 7 billion people on the planet, 1.3 billion
still do not have access to electricity. Almost half, 600 million, live in sub-Saharan Africa (two-thirds of the
continent's population), about 300 million in India, as well as in other Asian countries.
Each year, nearly 1,300
tons of lithium batteries and lithium-ion batteries are discarded. By 2020, this figure is expected to increase to
14,000 tons, 10 times more.
This problem can be remedied by recycling the batteries.
First of all we recycle laptop
batteries that have a long life
A faith in the laboratory we manufacture lighting kits with, for light source for
schoolchildren in rural areas

Hi Tamba,
What type of products will be manufactured at the Lab? Any design or prototypes developed?
What are the
materials required for the manufacturing?
How the recycling of batteries is carried out?
Tamba (Submitter) 6 months ago
Hi Rakesh10
Thank you for the interest for our project
Lighting kit composed of:
-mini solar plate and a rechargeable
The required materials:
-a 3D printer to print the box that must contain the rechargeable batteries and the
-components for making a charger
For recycling we intend to set up a collection system at the level of the
household and the companies
Or to link partners with specialty in the field of electronic recycling

This is a very useful thing for kids in poor countries. Even if they have electricity sometimes it is not
available 24/7 and they have few hours every day only!
They can use these batteries if they are cheap. Do you have any
idea about their price approximately?
Tamba (Submitter) 5 months ago
Hi Othman thank you for the interest
the other idea is to allow the local people to be able to reproduce them
themselves but we have not yet decide the price of sale

I really love the idea already there is a lot of battery contamination and we need great clean energies
me encanta la
idea realmente ya hay mucha contaminación de pilas y necesitamos energías limpias genial

Great approach! How many battery cells will be in one lighting kit? The kids will need a meter to test the batteries,
too. Is this included (and accessible) within the charger? Did you think about safety aspects (e.g. in the event of a
short circuit)? Very interesting!

A beautiful project ... and if implemented will be very useful ... but I propose to study the economic feasibility of
the process and compare with the alternatives to produce electricity and work to find a way to reduce their costs

hi TechUser thank
Like any manufacturing product there will of course be a notice with indications of use and
But I do not think the child will need to make manipulations on it also depends on their age

hi OmarHasayn Thank
We are not gifted for the economic thing and it is also important
For this we have to get closer to
the people who know it best
