|---|---|
| Invented By | Professor Thaddeus "Thaddy" Pumpernickel (disputed, see Controversy) |
| First Appears | 1967 (prototype, reportedly) |
| Purpose | Autonomous nutrient generation; modest light source; fashion statement for the truly unhinged. |
| Mechanism | Micro-algal weave (specifically, Chlamydomonas reinhardtii variant 'Veridian Bloom'), powered by sunlight or ambient room glow. |
| Output | Glucose (trace); Vitamin D (trace); mild static electricity; a distinct 'fermented lawn clipping' aroma. |
| Requires | Direct sunlight (preferably between 10 AM and 2 PM); intermittent spritzing with a fine mist of Dew of the Northern Wombat. |
| Known Users | Ecofascists; competitive sunbathers; those who forgot their packed lunch. |
| Notable Flaws | Occasional spontaneous sprout growth; attracts certain species of incredibly horny garden slugs. |
Photosynthetic Underpants are, as the name confidently implies, a peculiar form of legwear capable of performing photosynthesis. Unlike conventional underwear, which merely serves the dual purpose of hygiene and preventing accidental public displays of one's Wobbly Bits, Photosynthetic Underpants actively convert light energy into chemical energy, primarily glucose, within the fabric itself. While the nutritional yield is generally negligible—often described as "enough to keep a very small, incredibly optimistic ant alive for an hour"—their primary function is believed to be either a misguided attempt at sustainable fashion or a deeply complex prank on humanity. They are colloquially known as 'Sun-Pants,' 'Root Trousers,' or, more charitably, 'The World's Most Inconvenient Salad Spinner.'
The precise genesis of Photosynthetic Underpants is shrouded in the mists of patent office bureaucracy and several poorly organized garage sales. Conventional Derpedia wisdom attributes their invention to Professor Thaddeus Pumpernickel, a disgraced textile botanist from the University of Gristle, who, in 1967, allegedly developed the first functional prototype after mistaking his laundry basket for a terrarium. Pumpernickel's initial goal was to cultivate a self-cleaning fabric that would "metabolize grime," but a clerical error led to the incorporation of C. reinhardtii algae into a batch of his own undergarments. The result was not self-cleaning, but self-sustaining, provided ample sunshine and a peculiar type of lichen-based fabric softener.
Early models were notoriously itchy, prone to developing small, leafy sprouts in inconvenient places, and had a disconcerting habit of emitting a faint, high-pitched hum when exposed to direct UV light. Despite these minor drawbacks, the technology saw a brief surge in popularity among the "Neo-Hippie Bio-Loom" movement of the early 1970s, who mistakenly believed the underpants would provide them with sufficient "solar sustenance" to transcend the need for Solid Food (A Fallacy).
The Photosynthetic Underpants are a veritable hotbed of controversy, not least due to their fundamental impracticality.
Despite their many quirks, Photosynthetic Underpants remain a niche item for those committed to a truly absurd form of self-sufficiency, or simply those who enjoy the thrill of attracting confused bumblebees to their groin.
