##### ***A Low cost and Low Tech waterproof backpack***
##### ***A Low cost and Low Tech waterproof backpack***
#### Project Summary
After doing some researchs and talking to indians living in Kerala, we learned that a lot of people have lost valuable items during the flooding of the last summer. To prevent this from happening again, we decided to create a waterproof backpack so that people could protect and transport their personal belongings, like diplomas, certificates, family photos, precious and value objects during the flooding. It could also protect them in the relief camp from all the dirt there is on the ground. The bag is made out of tarpaulin which makes it really affordable, light and waterproof. The tarpaulin is also a really resistant material when the density is over 150g/m2. It can resist to scratches and impacts. Furthermore, this material is really common and easy to find in Kerala, which makes it easy to find and reduces the global cost of the bag. Our bag has shoulder straps to make it easier for people to carry. It also has two layers made out of tarpaulin to increase it's resistance to impacts and heavy loads. The joints are welded together using a straightener or an iron. This method seals perfectly the joints and allows stored items to stay dry. To close the bag, we have to roll the top 3 times to prevent the water from entering the bag. Finally, the idea is to upload the design in opensource by the fablabs's network. We will send the bag's template to the different FabLabs in Kerala, so they can cut with the lasercutter the patterns of the bags and send them to population. The indians can do the bags themselves with the instructions for use and the tarpaulin that they have or get. Our goal is to prevent the lost of valuable items which is a big part of the people's identity for the next flooding or disaster.

**Close the bag** **Tutorial**
To close the bag and make it waterproof, we have to roll it three times and close it with the leash. It's an universel system that works if we follow the good instruction. If the system is not well close the water will enter. So it's a fondamental step to keep the stuffs dry.

#### The 1 euro backpack
To make our project possible, the most important thing was to make it affordable so everyone could have access to it. So we calculated the prices of the tarpaulin in India according to the various dimension and the density that would be around 150-180g/m2. We noticed that it cost 5 times less in India for the same product and more we can do bags on one tarpaulin piece the cheaper it is.

To do it more low cost, the project must be very efficient. So we draw patterns as much as possible on different sizes of tarpaulin that we could find in India. So the most efficient would be to chose a tarpaulin with the dimensions 5,2mx3,4m. With that we can make 10 bags with the cheapest price : 0,77 €

#### Design Variation
The design we chose is to make a backpack with those technics ( tarp + heating ). But we could decline our product into various designs and dimensions with the same method.
