Making the best use of his time during the nationwide coronavirus lockdown, 30-year-old Telangana resident, Mupparapu Raju, developed a pedal-operated liquid soap and water dispenser machine.
According to a report in The Indian Express, in the last few weeks, Raju has built 10 such machines, which are presently installed outside offices of district collectors, municipal corporation, municipality offices, and police checkpoints.
“I was at home with my son and wife, and nothing much to do. After seeing something similar used by the Army, I thought why not try something here,” Raju told the newspaper.His pedal-operated liquid soap and water dispenser machine has a 500-litre water tank and 5-litre container for liquid handwash. "With a full tank, over a thousand people can wash their hands," Raju said.

Frequently Asked Questions
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
There are two pedals fixed on an iron frame. These pedals are connected to the taps using clutch cables used in bikes. The first such machine was installed outside the Karimnagar municipal corporation office. “It’s not a business for me. I am charging only Rs 1,000 per machine,” the 30-year-old told the paper.After Karimnagar municipal corporation, similar machines were installed outside Khammam district collector’s office, Khammam municipal office, Narasampetta municipal office, Mahabubabad bus station, Ameenpur municipal office, Mahabubabad municipal office, and at Girni Bavi police checkpoint near his home in Duggondi Mandal in Warangal Rural district. Another one will be installed outside the Nellikudur gram panchayat office soon.
