Hydrogeny – Evelina Domnitch & Dmitry Gelfand
Evelina Domnitch and Dmtry Gelfand’s recent work Hydrogeny consists of a tank of ultra-pure water scanned by a white laser sheet. Electrodes at the bottom of the tank liberate hydrogen and oxygen bubbles through the process of hydrolysis. Diaphanous bubble clouds and rise in bifurcating paths to the surface while a penetrating laser sheet reveals the intricate dynamics of the bubble flow matrix. The water is further transduced by sound which generates complex spatial configurations and vortexes within the bubble clouds. The streams appear iridescent as each of the bubble acts as a lens to reflect and refract laser light.
Continent, an new online journey, that attempts successfully to ‘map a topology of unstable confluences and traverse the interstices of alternative culture, theory and art’ has an unmissable article exploring Hydrogeny in greater detail.
Samuel Thomas von Sömmering’s “Space Multiplexed” Electrochemical Telegraph (1808-10)
Hydrolysis was proposed in 1808 by by the German physician, anatomist and inventor Samuel Thomas von Sömmering as method to transfer messages over a distance of a few kilometers. The Electrochemical/Bubble Telegraph receiver’s wires were immersed in a glass tube of water. An electric current was applied in a sequence by the sender through the various wires, each of which represented a digit of a message. At the receivers end the electrolysed water released streams of hydrogen bubbles next to each associated letter or numeral. The telegraph receiver’s operator would watch the bubbles to decode the transmitted message.
