Halo is a public installation constructed from wind, the sun, mirrors and water, gathering 40 kilowatts of solar irradiation using an array of 99 mirrors which move continuously throughout the day like sunflowers. These mirrors, arrayed across two 5 meter tall towers and one 15 meter long track, each emit a beam of sunlight into a cloud of water mist. The beams are computationally aligned so that together they draw a bright circle in the air. Dependent entirely on the presence of the sun for its completion, the work explores the possibilities and limitations of technology to capture what is out of reach, to harness nature and bring the sun down to earth. The installation offers a theatre for meditation within the city. The wind constantly causes the halo to arise and pass without control, mirroring the way thoughts act in the mind. Meanwhile the noise of the mist interacts with the acoustics of the courtyard dissolving the busy city beyond. Watching these transitions, the audience tunes into their own patience, and acceptance that much of their world is not on-demand. Halo’s open source technology brings together machine learning and computer vision to enable low cost concentrated solar farms - a valuable ingredient for weaning humanity off of coal and gas. Urban areas such as Seoul and central London have persisting air pollution concerns, and by keeping attention on powerful alternative sources of energy, we can better navigate towards solutions on the issues of air pollution and climate change.
