A Revolutionary Ground Breaking Invention of Green Energy Device by Dr R K Kotnala & Dr Jyoti Shah

I would like to apprise of our revolutionary invention of green energy device of Hydroelectric Cell working, which is India’s pride. It generates electricity instantly using water only with no acid /alkali. For electricity generation it does not require any light, electrolyte, catalyst and external energy. This invention has been covered in news about 76 times in different newspapers & NDTV,DD National,Rajya Sabha TV, etc even at international level during last 3 months only. Although Hydroelectric Cell invention news has been published extensively in The Hindu, Indian Express, The Telegraph, Deccan Chronicle, Economic Times, Rajasthan Patrika, Jagran Josh, DNA, Mail Today etc. including 12 foreign newspapers.

Top Energy magazines internationally have covered Hydroelectric Cell invention news recently - Energy News, Science World Report, Sciexaminer, ET-World Energy etc.

Global Leadership in Hydroelectric Cell ( HEC ):

It is exclusively a make in India energy device and its further development can place Hydroelectric cell in global leadership for green energy solution. The energy produced by HEC can be utilized in domestic residential applications in decentralized mode at low cost because conventional usage of electrical energy is associated with huge expense of electrical transmission and distribution. Production and usage of such cells is not capital intensive unlike electrical power generation systems.

Paradigm Shift in Green Energy:

A Green Energy Source with a potential to replace conventional solar/fuel cells.

It can be used as power source in rural area as phone charger, lighting of lamp, torch etc.

Fabricated hydroelectric cell of dia 4.8 cm has generated current density of 5 mA/cm2 and 950 mV voltage with maximum power of 74 mW. The Processing cost of the cell is quite low & economical.
