Around Five years back Bill Gates addressed at TED on upcoming pandemics might be faced by world in the upcoming day that time nobody noticed that but with the prevailing situation of novel virus Corona COVID-19, that video becomes viral all over which started new debate and  SPECULATIONS OVER CONNECTIONS OF BILL GATE AND COVID-19 Bill Gates is currently the most criticized in the United States and Europe. The main reason for the criticism is the video released five years ago in which Bill Gates warned the world not only about the virus similar to the novel Corona named  COVID-19 but also on the screen behind him.

Why didn't He come up with

Siobhan Treacy 23 April 2020 Researchers from the University of Pennsylvania’s School of Engineering and Applied Science have created a metal-air scavenger (MAS) that powers robots by eating metal. The new device bridges the gap between batteries and harvesters. Like a traditional battery, the researchers' MAS starts with a cathode that's wired to the device it's powering. Underneath the cathode is a slab of hydrogel, a spongy network of polymer chains that conducts electrons between the metal surface and the cathode via the water molecules it carries. With the hydrogel acting as an electrolyte, any metal surface it touches functions as the anode of a battery, allowing electrons to flow to the cathode and power the connected device.

Harvesters collect energy from the environment, but they can only operate in certain conditions and cannot quickly t
