It was evenly spaced and extended way ahead of me. Where could it lead? It took some time for my sensitive eyes to adapt… Continue reading Entering a dark, humid cave – lit up by cat-eyed, yellow fiery flies – could turn your thinking upside down.

By William Van Zyl Thinking of the sustainability of a cave is not something that comes to mind naturally. It requires prompts: What choice of materials is best for constructing the walkways? What type of lighting is best? Could the electrical system of the cave be powered via solar power? To what extent could sensors,… Continue reading Sensors: Maintaining the eco-equilibrium of sensitive limestone caves in New Zealand.
