Interactive living oxygen generator, here part of ON THE ROAD AGAIN in Künstlerhaus Vienna
from Febr. 18th to May 21st, 2023
Paul Gründorfer made the reactive sound design for the interactive oxygen generator >> more info below

LIVE PHO2TOSYNTHESIS PERFORMANCE
interactive living oxygen generator
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.
Full installation with:
upper aquarium: bladderwrack, gutweed, green hair weed, water, marine salt, LED lights
in the middle: diatoms and nannochloropsis salina > micro algae, marine salt, loudspeaker,
microphones, cables, tubes, pump, oxygen masks, paper mouthpieces, LED lights
below: bladderwrack, toothed wrack, water, marine salt, wood, LED lights,
recycled bottles and framing of galvanised
waterpipes (steel, party recycled)
Algae (micro- and macro algae) produce over fifty percent of our atmosphere’s oxygen. Statistically every
second breath you take is produced by alga. In turn, they metabolize the carbon dioxide you exhale.
There is a continuous cycle of matter between your lungs and algae
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!
By blowing out CO2 in the tank the visitor becomes part of the algae's
Live photosynthesis performance - the participation effects the sound of
this biochemical process, that we made audible for the human ear
for interspecies communication
