MegaChallenge The global refugee crisis is ongoing and continues to grow with every conflict. With limited basic resources and abilities, refugees face uncertain futures and struggle to lead secure lives. From here, the "Design Solutions for Refugees Challenge" program was launched. Motivated by humanitarian efforts to alleviate hardships that have altered the course of countless lives, Tanween presents an opportunity through its mega challenge for innovators from all over the world to provide solutions that address this global crisis by creating sustainable and empowering solutions that improve the quality of life of refugees inside camps around the world.

The Challenge
Solar panels hold great importance within the camps at Cox's Bazar, serving as a source of hope and providing essential services. However, due to inadequate repair and maintenance support, along with a lack of local expertise, many of these systems do not function properly, which not only affects their well-being but also contributes to the issue of electronic waste
Research Process
1. One to One Interview Meeting with Siraj, a camp resident
2. Case Study Research 4 scientific papers talk about energy in cox bazar camp
3. Process of Observation Observing local residents in the camp by photos and videos

75% of the Rohingya refugee population in Cox's Bazar, Bangladesh has no access to mains electricity
Problem Statement The Kutupalong Refugee Camp in Cox's Bazar, Bangladesh, is grappling with a severe shortage of accessible and sufficient electricity. This deficit impacts essential services, safety, and overall living conditions for its over one million Rohingya refugees. Addressing the electricity crisis in the camp is critical to enhancing the well-being and quality of life for its residents.

Design Parameters 1. LI BATTERY lithium ions (Li+) move between the cathode and anode internally. Electrons move in the opposite direction in the external circuit. This migration is the reason the battery powers the device—because it creates the electrical current 2. GRAVITY BATTERY is a type of electricity storage device that stores gravitational energy, the energy stored in an object resulting from a change in height due to gravity 3. CLAY BATTERY Filling the jar with an acidic liquid, such as vinegar or fermented grape juice, and you have yourself a battery capable of generating a small current. 4. SAND BATTERY storage that uses sand or sand-like materials as its storage medium. It stores energy in sand as heat.

Feasibility Sand Battery
• Bismuth(III) telluride is available in the market and can be easily purchased anywhere. •
In a feasibility study done by Fransisco Montero, a professor at University of Chile in 2022. The study shows that the calculated levelized cost of energy (LCOE) of the HPV-TEG system is 0.071 USD/kWh.
• This cost is relatively low and quantifies the advantages of HPV-TEG system over current solutions and opens the possibility for HPV-TEG systems to be competitive in the market.
