Illuminated Cacti
There are methods related to the textile and its processes, by means of which it is possible to generate electricity, for example, in a saline water slope there is a salt, called in Quechua “qollpa”, used ancestrally as a mordant to dye the fibers, fixing ingredient and toner If a multi-meter is simply placed on the slope, the reading will give at least one volt. This makes us think of the electrochemical power of natural dyes.
Another example is the Airampo (Opuntiae Cochabambiensis), dyeing cactus endemic to the Cochabamba Valley, which served from ancient times to dye fibers in different shades of violet. From a basic electronics exercise, electrical circuits are used, connecting the cacti with LEDs, and in the dark of the night, the energy they contain can be visualized.
