Kyoto box is a simple solar oven used extensively in Africa. Assuming a square box with four reflectors of L = 75 cm, on a sunny day with direct sunlight from the zenith, what is the optimum angle ?? What is the total solar power received by the box?

If the efficiency is 70%, how long will it take to heat 1 gallon (3.785 liters) of water from 25°C to the boiling point?
