At first glance, Here Comes the Sun does not announce itself loudly. Installed in the Ratskeller of Cercle Cité, the exhibition avoids spectacle in favour of something slower, more demanding and ultimately more rewarding. Curated by Elektron, the platform founded by Françoise Poos and Vincent Crapon, it asks visitors to pause, recalibrate their gaze and reconsider what intelligence, progress and responsibility might mean in an era shaped by climate instability.

Organised by Cercle Cité with the support of the Luxembourg Film Festival and the Ministry of the Environment, Climate and Biodiversity, institutional involvement is not incidental. As Premier Échevin Maurice Bauer noted at the opening, the show sits precisely at the intersection where technological ambition and environmental limits collide. Luxembourg often presents itself as both a smart city and one of the greenest in the world. Reconciling those identities remains an unresolved challenge.

Rather than offering solutions, Here Comes the Sun insists on asking better questions. “What if intelligence were not what we believe it to be?” Françoise Poos asked during the opening. “What if, while we are building increasingly sophisticated machines, we are overlooking the oldest, most efficient, and most generous forms of intelligence on this planet?” That provocation sets the tone for an exhibition that resists easy optimism and technological hero narratives.

The show unfolds in three works, each addressing the sun not as symbol but as system, force and limit. The most overtly cinematic work is Alice Bucknell’s Staring at the Sun, a video installation imagining a near future in which solar geoengineering has become humanity’s last gamble. Presented through game-like aesthetics and layered interviews, the film navigates the murky territory where technological intervention meets ecological hubris. Bucknell draws on real-world debates around stratospheric aerosol injection, a controversial technique that proposes reflecting sunlight back into space by dispersing particles high in the atmosphere.

The work resonates uncomfortably with current events. Since 2022, the US-based start-up Make Sunsets has launched balloons containing sulphur dioxide as part of a commercial experiment selling so-called cooling credits. Mexico swiftly banned such deployments over its territory, citing environmental and health risks. Scientists continue to warn of potential side effects, from ozone depletion to altered weather patterns and respiratory harm. Bucknell does not list these dangers explicitly. Instead, she lets unease seep in through tone and character. One particularly slick advocate for geoengineering, all aerodynamic glasses and salesmanship, inspires little trust. The sun itself, rendered in rippling, fiery detail, becomes the dominant presence. Power shifts away from human confidence towards something vast and indifferent.

Bucknell has said that staring at the sun is foolish and painful, yet necessary. Blindness becomes a starting point. Perhaps only by acknowledging how little we see can clearer thinking emerge. The film leaves viewers with a question rather than a solution. Who gets to decide when planetary systems become experimental terrain, and on whose behalf?

If Staring at the Sun confronts technological overreach, Solar Protocol offers a quieter but equally radical alternative. Developed by the collective led by Tega Brain, Alex Nathanson and Benedetta Piantella, the project imagines an internet powered entirely by solar energy and maintained collectively by volunteers around the world. A circular projection evokes both the sun and the vulnerability of being at sea, dependent on forces beyond control.

Here, websites are hosted wherever the sun is shining most brightly at a given moment. When daylight fades in one location, another takes over. The system is deliberately fragile. It slows down, pauses and adapts to weather conditions. In doing so, it exposes a truth often obscured by the seamlessness of digital life. Technology is not immaterial. It depends on energy, infrastructure and human care. At a time when data centres account for a rapidly growing share of global electricity consumption, this acknowledgement feels urgent.

The power of Solar Protocol lies in its refusal of dominance. It suggests that technological systems could learn from natural rhythms rather than overriding them. It also restores a sense of agency. In contrast to narratives dominated by tech billionaires and opaque platforms, the work reminds us that collective alternatives exist. They require curiosity and commitment, not blind faith.

James Bridle’s Radiolaria series completes the exhibition by shifting attention far beyond human timescales. Four solar panels, etched with intricate patterns, appear at first like abstract mandalas. Look closer and their source emerges. Radiolarians are single-celled marine organisms, invisible to the naked eye, that have existed for over 500 million years. Their delicate silica skeletons display extraordinary geometric complexity, optimised over geological time to capture light and survive.

By inscribing these forms onto solar panels, Bridle collapses distinctions between ancient biology and contemporary technology. Evolution appears as the most sophisticated research and development programme imaginable, vastly outpacing human innovation. Intelligence, the work suggests, did not begin with algorithms. It has been quietly refining itself in oceans and ecosystems long before us.

Taken together, the exhibition demands time. Its impact is not immediate, and that is deliberate. The works resist quick consumption or easy optimism. They ask visitors to sit with uncertainty, to recognise limits and to reconsider what progress might look like if humility replaced control.

This approach feels especially relevant now. According to the European Environment Agency, the EU remains off track to meet long-term climate targets without deeper structural change, despite short-term emissions reductions. Luxembourg has made significant investments in renewable energy, yet consumption patterns and digital expansion continue to exert pressure. Against this backdrop, Here Comes the Sun positions art not as decoration but as a critical tool, capable of reframing debates that too often become technical abstractions.

Leaving the Rathskeller, one does not emerge with answers. Instead, there is a heightened awareness of complexity and interdependence. That may be the exhibition’s quiet achievement. In a culture saturated with certainty and speed, it reclaims thinking as an ethical act. This, perhaps, is the first step.

Here Comes The Sun is hosted at the Raskeller exhibition space on rue du Curé, Luxembourg City. It is open daily from 11-19:00 until 4 April and entry is free, cerclecite.lu

Over the coming months, Cercle Cité will host various connected conferences, covering themes such as the sun’s role in cinema (26 February), terraforming (25 March) and the city of the future (21 March).
