(H)eating together for a cooler Earth

What if we could nourish ourselves and the environment, with only the power of the Sun?

The Aeroreflector invites a collective turn towards the most important energy source for earthly life, the Sun. In positioning our tools-for-change towards it, we enter into an active multi-directional relationship with our brightest shining star, forming an act of hope-filled togetherness and solidarity with the Earth’s surface albedo. In becoming more familiar with direct solar energy, discovering the warmth from this life-providing star and the ocean of air through which it transmits, we can rearticulate the way energy and heating power has been (ab)used since the dawn of a human-influenced geologic age. Turning our attention to new circular modes of nourishing each other and the planet simultaneously, we enter a reflective practice; one in which we attune to the Earth, adhering not only to ourselves but interplanetary rhythms, other species and nature itself too, through a multidisciplinary attempt to understand how the sun made us, and what the sun could make of us, if we begin to sense it differently.

1 - Attune to the weather

If the sun doesn’t shine, we adjust, collectively embodying a practice of planetary attunement.


2 - Unscrew the handle

Be careful: smooth and slow moves.


3 - Get your foundation together

Attach the four-peg support structure to the base of your emissions-free solar oven.

4 - Attach your solar cooker

At the top of the spike is the central focal point, where maximised solar energy is captured. Put your pot here, embraced by the four-peg structure.



Attach the spoon/fork supplied to the unhinged handle, making it an handy-long tool to protect your hands from the heat emanated by the Aeroreflector.


6 - Make use of the most abundant source of energy on Earth. Solar Energy.

A transparent heat trap around the pot lets in the sunlight and holds in the heat. Shiny reflectors capture extra sunlight from an area about three times as big as the pot.

7 - Warming instructions

Set the cooker on a dry, level surface in direct sunshine, away from potential shadows. Put ingredients in the pot. Turn every 15 min in alignment with the Sun’s movement. If the weather is optimal, you can even boil or barbecue your food.


8 - Join the Earth’s surface albedo

Redirecting the energy of the sun away from the surface of our Planet, helping to cool the Earth down in the process.



Never leave the umbrella unattended; do not place your hand directly in the focal point.

The Aeroreflector joins the Earth’s surface albedo in redirecting the energy of the sun away from the surface of our Planet, helping to cool the Earth down in the process.

Subverting the individualised functionality of the umbrella as a tool for self-protection from the rain or rays of Sun, the Aeroreflector’s inversion transforms the umbrella into a speculative tool for communal activity and aerial attunement.

In the age of the Anthropocene, reframing the use of the umbrella invites us not only to solidarise ourselves with our planet Earth and its surface albedo, but further to reflect on the extractive relations of our fossil fuel milieu. It’s entailed inherent inequalities proliferate into the air, creating a human-driven thermodynamic shift that has redefined the life-giving energy of the Sun as a threat, experienced by the consequences of Earthly warming.

Based on a truncated pyramid concept developed long before the Anthropocene, the parabolic structure of the Aeroreflector reveals generational connections across various cultures, materialising methodical parabolic techniques, essentially formulating a solar thermal collector for heating. The concept of concentrating light using curved mirrors has historically helped civilisations to use collective efforts to heat, cook, and to share meals from renewable energy sources, collaborating with simple forms of abundant elemental energies instead of the extraction of commodity fuels for combustion-based process of heat generation, at the expense of all natural phenomena, ourselves included.
