  • 13. BUDGET & COSTS & PROFITS • The full system’s costs at test phase was close to 2150/- • But under mass scale production of the system can bring down this to a price as low as 1800/- • So we proposed that our Portable Refrigerator can be sell in to the market at a 2000/-
  • 14. TEAM REFLECTIONS Overall we must say that looking back at our achievements, we think it was worth the time and effort and was not bad at all. During this project, We have learned a lot of things ; • Skills of organizing ideas • Respecting others ideas • Team co-ordination skills • Technical stuff in a Fridge • Report writing skills • Presentation skills • How to deal with friends of different ethnics • Time-management
