As the country is reeling under the horrific second wave of pandemic and acute oxygen shortage, a start-up in Hyderabad came up with a invention to address the crisis. 'The Phi Factory' has created a portable oxygenerator, which works on Hydrogen Peroxide, under the name 'Project Vayuputra'. Vayuputra has been developed with an objective to support COVID-19 patients who are under home isolation. Price of this oxygenerator would be around Rs. 2,500 to Rs. 2,600 that includes the oxygenerator along with 10x2 liter bottles of Hydrogen Peroxide.
