MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541084384 A) filed by Dr. S. Rajesh; A. Harish; S. Thiyagarajan; and B. R. Viswanathan, Chennai, Tamil Nadu, on Sept. 5, 2025, for 'energy-efficient vertical farming system.'
Inventor(s) include Dr. S. Rajesh; A. Harish; S. Thiyagarajan; and B. R. Viswanathan.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "A portable, energy-efficient vertical farming system is disclosed. A compressible GI-sheet frame supports a base fish tank and stacked media-filled grow-beds that function as both plant support and biofilter. A recirculating hydraulic loop continuously converts fish-generated ammonia into plant-available nitrate and returns clarified water to the fish tank, enabling up to ~90% water savings. A solar-assisted power subsystem with battery backup supplies a pump, Wi-Fi microcontroller, sensors (pH, water level, temperature, humidity, ammonia proxy, light; optional NPK and grow-bed moisture), and optional LED grow-lights. The controller executes sensing and control modules for automated operation and user alerts, with a mobile dashboard for real-time monitoring and manual overrides. Representative embodiments demonstrate compact volumes, high turnover rates, robust structural margins, and suitability for leafy greens and tilapia. The system and method deliver dual outputs (plants and fish) with low cost, minimal footprint, and resilient, year-round production for urban and peri-urban users."
