Cleaning light instead of purgatory to fight the epidemic

In response to the security measures in the wake of the coronavirus, Studio Roosegaarde has come up with a concept called Urban Sun, which involves cleaning the air with UV-C light.

The main mission of Dutch artist Daan Roosegaarde and his team of engineers is to connect people and technology in a variety of artworks that improve the quality of everyday life in urban environments and bring colour to grey everyday life by combining sustainability with creativity. This is how the Urban Sun concept was born, inspired by scientific analyses of the treatment of respiratory viruses by light.

The technology is based on UV-C light, a narrow subset of UV light. It has little effect on humans when used in small doses, but it is quite effective in neutralising viruses. The Dutch National Metrological Institute has also confirmed that the light complies with the International Commission on Non-Ionising Radiation Protection’s safety guidelines for ultraviolet light, making it completely safe for human use.

The concept is already available in a range of sizes, and more sizes are under development, so that it will be possible to shine UV-C light on an ever wider range of people. The trick, however, is that ultraviolet light is invisible to the naked eye, so Urban Sun reflects the sun’s light to make the area to be cleaned visible.

The design team has stressed that while this can help make spaces safer for COVID-19, it is not a substitute for any other measure and is not a stand-alone solution to prevent the spread of the coronavirus.

They added that it was a great addition and they hoped that it would help to make it possible to organise cultural events bringing together large groups of people as soon as possible.
