Monocerosim: it will be the first an artistic style that influences the entire planet at the same time.
A young student will have crafted in her garage (there is always a garage) a prototype of a H.H.W. - Harvesting Hertzian Waves. Her younger sister ended up putting a sticker of a unicorn on the prototype because it reminded her of a unicorn's horn. It ended up being presented to scientists around the world as a unicorn. Years have passed and all energy consumption has changed to something really clean, zero carbon. People all over the world have come to see this symbolism as a sign of hope. Everything was influenced by this technology, the arts, music, architecture, fashion. Monocerism is a way of life, which uses simplistic lines to achieve the same result "minimum consumption from A to B". Straight lines to avoid consumption as much as possible.
