As a young man, 39-year-old Mandaji Narsimha Chary was a science fanatic experimenting on small ideas since the age of 12.

Growing up in government schools of Navipet town of Nizamabad district in present-day Telangana, Chary would spend hours sitting in his father’s furniture workshop, opening electronic equipment, tinkering with tape recorders and experimenting on various ideas.

In early 2000, he brought glow back to lakhs (1,00,000) of dead tube lights meant to be discarded after use.

"I finally developed a method to re-light discarded tube lights by developing an integrated circuit sometime in 2000. See, these tube lights fail once their filaments open up, and thus lose their capacity to generate the necessary voltage to light them up. Through trial and error over the next decade, using my own pieces of equipment, I first succeeded in lighting a failed tube light with choke and starter," he tells Newslions Media Network.

Recently he pushed his inventions to another level.

After several experiments, he has managed to patent his tube light idea to fight the novel coronavirus.

"To kill coronavirus, or in fact any virus or bacteria, we need a certain frequency of ultraviolet light, at around 207 to 220 nanometres. Everyday tube lights have a maximum 60-70 nm frequency of UV light. Using various electrical components I have managed to push it 800 and above," he claims.

The filament-less lights that Chary produces are capable of killing coronavirus in everyday homes.

Also, the tube lights he produces employs white light and not the blue ones that are hazardous to human health.

"I am using discarded tube lights to build my coronavirus killing device. Hence, the mercury that used to be discarded along with the bulbs is not polluting the environment. Very soon I will be able to produce zero mercury lights with ultraviolet capabilities," Chari says sounding hopeful.

Currently, Chary requires investors to be able to produce at least a lakh of these bulbs that can kill coronavirus and help stop the global pandemic.

"People can simply put these lights up in their homes and stay safe, I am hopeful about this invention, I am just waiting for mass production so that I can actually make a difference to the people's lives," he concludes.
