In a readers’ question and answer column, contributors discuss two related topics: where humans have not been, and where solar power should be sited. One reader asks whether there are places on Earth that humans have not visited and, if so, why they remain untouched. Another new question, prompted by a recent internet meme, asks why solar panels are placed on “green space” for solar farms rather than over large car parks. The column frames both issues as questions about access, land use, and practical constraints rather than making a single claim about either topic. It invites readers to send answers and additional questions, with a selection of responses planned for publication in a subsequent edition. The debate over solar siting focuses on the idea of using already developed, paved areas to generate electricity, while the question about unvisited locations centers on the feasibility of reaching remote areas and the reasons some places remain outside human activity. The exchange continues through reader submissions.
