The answer to the previous question is A, solar hot water. This monitoring equipment gathers data on weather conditions such as temperature and humidity, and the performance of solar hot-water collectors. The manufacturer, SolarWave Energy, has designed the product for installers to spot problems and for utility grid planners to measure the impact of solar hot water systems on natural gas use. This isn't really a fair question (you'd have to be a sensor expert to know the answer), but I had to introduce an element of luck into this!
Next question: What is the name of the wind turbine part pictured here?
