You are tasked with building a solar power plant in the Arizona desert, using solar panels with 10% efficiency. How large an area (km2km) must your solar panels cover to match the power output of a large nuclear powerplant (about a Gigawatt)? Please enter your answer in units of km2

Answer 1

A concave mirror would be best suited for use in a solar cooker because it reflect and focus the sunlight at a point. The temperature at that point increases which heats and cooks the food placed at that point.
