According to incomplete statistics from the World Animal Protection Association, there are about 600000000 stray animals in the world, mainly composed of stray cats and stray dogs. They drink water sources containing a large number of germs for a long time, endangering their lives and health. Studies have shown that the average life span of cats and dogs is 10-15 years, but the average life span of stray cats and dogs is only about 3 years. This is an infrastructure designed for the healthy development of the city, and we name it "endless". It can not only store garbage, but also solve the problems of urban lighting and drinking water for stray animals in a low-cost way. At the top of the equipment are solar panels, which can rely on photovoltaic power generation technology to provide energy for street lights. The green part is its porous structure that captures water vapor from the air, then condenses and transports it directly to the bottom storage bucket, providing a clean water source for stray animals. At the bottom of the device, there are two drinking ports, one high and one low, which can satisfy both smaller cats and larger dogs. The design of this product aims to change the single existence of urban infrastructure and reflect the harmonious symbiosis between the environment, people and animals.
