The fungal network feeds on coffee grounds and ambient humidity, generating a few hundred milliwatts enough to keep a phone or tiny LED lamp alive. No batteries, no plug‑in, just a living charger. Pair it with a low‑profile LED indicator that glows when the mycelium is thriving. Ideal for home offices where the HOA enforces no‑wire policies. low battery. Light drizzle 3°C
