Ancient Moche artists created an exceptional level of ceramic art over 1,500 years ago when this culture prospered along the arid north coast of Peru. They produced realistic three-dimensional ceramic forms of people and animals, and they decorated vessels with exquisite fine-line drawings. Several aspects of Moche ceramics recently caught my interest, especially the realistic ceramic animals and the drawings of supernatural creatures.
Many researchers are working on new and intriguing renewable energy storage sources. Interesting approaches for gravity, compressed air, and thermal storage are under development. A few of these, each based on relatively simple mechanical engineering fundamentals, have captured my interest and I describe them in this post.
Renewable energy from sunlight, water, and wind plays an important role worldwide—and renewable storage is essential to reduce imbalances between energy demand and energy production. We need to develop much more storage capacity; fortunately, there are efficient storage technologies already in use, as well as innovative alternative approaches under development.
