Problem Addressed
Streetlights left on during daylight hours consume energy. The innovator estimates four hours of electricity wastage daily in rural areas with lights switched on between 5 pm to 9 am.
Technology
The non-stick substance used in Hariyali Handi comes from lalic insects that inhabit Pohim
trees. It is made by boiling raw lac twice, brewing a homogenous solution. When applied to hot earthenware, it seeps into the porous clay and hardens into a uniform coating.
Societal Impact

A six-month trial in ten villages found that the device reduces electricity bills by approximately
25-30%.
Current status
Over 500 villages in Telangana have adopted the innovation, installed through his enterprise, Raja
Innovatives. He gained recognition from Palle Srujana and Telangana State Innovation Cell. He is receiving
incubation support from NIF. His other innovations include a foot-operated sanitising device, corn husk pens, and a solar powered mobile charger. The idea may not be totally new but its design and implementation efficiency has made it very popular.
