Andhra Researcher's 1-Gram Wind Turbine Enters World Record Books
A wind turbine lighter than a paperclip and smaller than a fingernail just earned a spot in the International Book of Records, built by a researcher in Srikakulam using copper sheets and a tiny motor.
1 gramweight of the record-setting turbine
The facts
- 1Maheswaram Bhanu Chandhar, a researcher from Srikakulam in Andhra Pradesh, built a wind turbine just eight millimetres wide and weighing one gram.
- 2The device is assembled from thin copper sheets, a small DC motor, and enamel paint, materials found in basic electronics workshops rather than specialised labs.
- 3Its design allows the blades to spin without the whirring noise typical of larger turbines, producing a small electric current silently.
- 4The International Book of Records verified the turbine's size and weight, recognising it as a new benchmark for miniature wind-power devices.
- 5Chandhar says the compact, noiseless design could one day power sensors on satellites or small robots, where both space and silence are limited resources.
Why it matters
The project shows that meaningful scientific innovation doesn't always need expensive labs, and it points to a real gap: today's tiny turbines can prove a concept but still generate far too little power for practical devices.
