    Is an interesting concept, but not without some issues to solve. How they maintain an inmaculate ice pyramid in a windy place full of dust and sand for example. Dark sand will trap heat.

    On the other hand ponds and water tanks seem a more efficient way to achieve the same result without risking algae growth and debris. Ponds can be used to grow food so they serve more purposes. Recycling waste, culturing fishes and use the water later for vegetables. Chinese are doing the same since thousands of years.
