LIVE PHO2TOSYNTHESIS PERFORMANCE

Sound of Photosynthesis: Karl Stirner

Above and below you see an interactive living oxygen generator. It is filled with microscopic

marine algae and seaweeds from the North Sea coast of the Netherlands: diatoms and

other phytoplankton, Bladderwrack, Sea whistle, Devil’s Apron, Green Hair Weed.

Algae produce over fifty percent of our atmosphere’s oxygen. Statistically every second breath you take is

produced by algea. In turn, they metabolize the carbon dioxide you exhale. There is a continuous cycle of

matter between your lungs and algae cells in the oceans and waterways of the planet.

You and algae are inseparably connected.

The sound you hear is the fizzing and fizzling of photosynthesizing algae otherwise inaudible to

the human ear, each sound an encounter between your breath and the chlorophyll-containing algae

cells, the transformation of light into chemical energy and the crescendo of gas metamorphosis.

Blow out in the machine and sing with the algae!

The CO2 you breathe out becomes part of the process of photosynthesis

that we made audible for the human ear.
