2. VACCINE REFRIGERATOR OVERVIEW OF IDEA:
One in four children born each year does not receive proper immunization
Three million of these will die due to vaccine-preventable diseases
Lack of immunization causes ~8,000 deaths a day
What it is
-Also, varying forms of transportation available in different countries:
-cars/vans
-motorcycles
-camels
What are the major issues and how we are solving them

3. VACCINE REFRIGERATOR APPROACH: Existing vaccine refrigerators:
Marginally portable (need wheels or animal to transport)
Use high cost solar cells and need battery replacement
Our idea: Backpack refrigerator
Continuous power generation

-Also, varying forms of transportation available in different countries:
-cars/vans
-motorcycles
-camels

5. VACCINE REFRIGERATOR TECHNICAL FEASIBILITY: MARKET: COP ~ 1.5
Power input = 3W (comes to ~56 min. pumping per day)
Time to cool air100F - 38F ~ 20sec. pumping
Target weight of backpack < 30lbs.
MARKET:
Non-profit organizations that immunize villages and communities in the third world by going door to door.
$30,000 per year: average amount spent by a developing countries on cold chain supplies
Tech details:
Max hiking weight (comfortable) ~45lbs
Assume: sustainable power output pedaling - 60W
volume of fridge - .03m3
heat loss W
surface area m2
