Pouring water on nano-tube produces electricity: Sibal

New Delhi, Mar 16 (UNI) Scientists in Bangalore have found that electricity is produced by pouring water on nano-tube, Science and Technology Minister Kapil Sibal informed the Lok Sabha today.

Scientists of the Indian Institute of Science and Raman Research Institute have discovered that the flow of a liquid like water on single walled carbon nano-tube bundles induces an electrical signal (voltage/current) in the sample along the direction of the flow, Mr Sibal said in a written reply.

The electrical signal is found to be logarithmic in the flow speed over a wide range. The magnitude of the flow induced electrical signal depends on the ionic conductivity and polar nature of the liquid.

''The invention reported so far only establishes the existence of this new effect,'' the Minister said in reply to a specific query on whether commercial production is possible through this technique.

The scientists at Bangalore are pursuing further studies on this new effect, he added.
