Solar thermal technologies can be used for water heating, space heating, space cooling and process heat generation. In 1878, at the Universal Exposition in Paris, successfully demonstrated a solar steam engine but could not continue development because of cheap coal and other factors. So they work by absorbing light, not heat, from the sun. Solar panels even have an anti-reflective coating that increases sunlight absorption, allowing the cells to soak up more sunlight. [pdf]
