MANGALURU: Rajendra Prasad,43, from city is not an environmental engineer. However, his love for nature pursued him to innovate \'Smoke Guard\', a prototype electrical device, which reduces carbon emission from industrial units. Rajendra, a motor winder, took nearly six months to produce a prototype of smoke guard that reduces smoke into ash. Smoke guard, if modified, can be used for small, medium and mega industries, said Rajendra. who has over 20 years of experience in winding of armatures. He was a PU arts stream student. However, he was unable to pursue higher education due to conflict of interest in studies.
\"The conversion of smoke into powder takes place in smoke chimney units of industries. The smoke guard comprises an electrical transformer unit that converts 230 volts into 18,000 volts. The stepped up alternative current power from the transformer unit is converted into direct current. Later, DC volt is passed through high volt anode and cathode electrodes inside the chimney and converts smoke into powder carbon.\" \"The same powder carbon is absorbed and collected in separate chamber through vacuum pressure,\" he told reporters adding that the smoke guard process can effectively reduce carbon emission from industrial units.
He said that he spent nearly Rs 10 lakh to reach the final stage. \"Initially, I designed five designs and later with modifications and improvements, the prototype of smoke guard has been prepared. A small industrial unit can be equipped with smoke guard by spending approximately Rs 1.5 lakh. I have applied for patent and I am also in touch with major national companies too,\" he said. adding that he is ready to hand over the technology once the patent process gets over. Rajendra, who had designed a pressure-based water tank level indicator, is also preparing to design a new device to reduce carbon emission in vehicles.
