1 POWER GENERATION IN DEVELOPING COUNTRIES
Savonius Rotary Battery Charger THE CLIENT Municipal Governments of Developing Countries Humanitarian Relief Organizations THE NEED 130 Watt Off-Grid Car Battery Charging 12V 36Ahr battery 3 hour charge time throughput: 3-4 batteries per day renewable energy source target cost: $600 per unit less than $5 per charge to customer Kinkajou’s targeted use in developing countries necessitates that power be provided independent of an electrical grid. It is representative of a range of low-power appliances that are too big for a hand-crank and too small to justify the cost of solar power. Extremely ambitious target cost of $25.

2 Environmental Conditions
POWER GENERATION IN DEVELOPING COUNTRIES Savonius Rotary Battery Charger Environmental Conditions Wind Speed Average 7 to 10 mph inland Average 10 to 15 mph coastal Maximum: 35 mph Requirements Startup speed: 3 mph Elevated turbine The most common power source found in Mali, where the Kinkajou has been field tested, is a 12 V DC lead acid battery, typically used in car/truck or motorcycle applications.
