The Solar Pipeline: An Alternative Energy Source

The quest for alternative energy sources is becoming increasingly pressing as the resources of our planet are finite, while society's energy consumption needs are growing exponentially. Harnessing solar energy is not a new concept, with scientists having already developed several useful inventions powered by it. Solar panels and collectors are now commonplace, although not accessible to everyone due to their relatively high cost. Today, we introduce a new method of obtaining alternative solar energy — the solar pipeline.

The name itself sounds unusual since we are accustomed to pipelines being used for transporting various fluids or gases, whereas here, it's about transporting sunlight. Nonetheless, British specialists have conducted research and found that to illuminate living spaces with natural sunlight instead of artificial light, there is no need to convert solar energy into electricity. Building a system of special solar pipelines is sufficient.

Looking at the issue from a historical perspective, humanity has made attempts in the past to use sunlight rationally to meet its needs. Examples include dormer windows, modern mirror systems, and fiber optic lines. However, these inventions have significant drawbacks — either low quality or a high cost.

According to SunPipe developers, this device overcomes all the shortcomings of its predecessors. The system can transmit sunlight without light loss for a distance of at least 10 meters, which is typically sufficient for illuminating a private house. Using a solar pipeline in places like bathrooms or basements is particularly convenient and cost-effective, eliminating the need for windows or electric lights.

How does the SunPipe solar pipeline system work? Its external part consists of a transparent dome made of incredibly durable polycarbonate. This material retains transparency for a long time, ensuring the device's efficiency. The pipeline itself is made of aluminum, coated with silver spray on the inside, polished to a perfectly mirrored state. The pipe's diameter ranges from 30 to 40 centimeters, with walls no thicker than a millimeter.

Thanks to this design, SunPipe can be installed not only in a building's roof but also in walls and even floors. Tests have shown that sometimes the sunlight intensity is so high that additional regulators are needed to address this issue. Another significant advantage is that the pipeline blocks harmful ultraviolet radiation, making the system safer. SunPipe has been tested in 16 countries, with verification results justifying investors' contributions.
