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

ScottishPower Renewables announced that 102 Wind Turbines Installed at East Anglia One,  The Popular  offshorewind.biz  revealed that,  DEME’s  Sea Installer  and  Sea Challenger  vessels have been installing the Siemens Gamesa 7 MW offshore wind turbines at the project site, located 43 kilometers off Suffolk, since June 2019. Wind turbine components were pre-assembled and loaded out from Peel Ports Great Yarmouth. ScottishPower Renewables said that, during the East Anglia wind turbine installation, the company also reached a milestone of installing its 1,000th megawatt of offshore wind power. Furthermore, Siemens Gamesa marked the installation of its 1,000th Direct Drive offshore wind turbine during this project. East Anglia ONE generated the first electricity in September 2019. Once fully commissioned, the 714 MW wind farm will produce enough electricity to meet the annual demands of the equivalent of over 630,000 homes. The project’s offshore substation (EA1 OSS

In the fear of COVID-19 all over the world,  This week, two things that I thought was great news for people and researchers  1. A study by USC shows that 4.1% of the population in Los Angeles has developed the Covid 19 antibody. I thought it is because they might be exposed with COVID-19  and after mailed/ hidden indication and their body developed an antibody to fight COVID-19 off. USC and L.A. County Department of Public Health officials have released the preliminary results of their antibody tests, which show a surprising number of residents have been infected with the coronavirus. for further you can go to the link below.  https://news.usc.edu/168987/antibody-testing-results-covid-19-infections-los-angeles-county/ 2. A New York state study shows that 21.2% of New York City residents have developed the COVID-19 antibody. 13.9% of residents in the state have the antibody.  Antibody Test Estimates 1.7 Million NYC Residents Have Had Coronavirus  https://nymag.com/intel

NASA astronauts Christina Koch & Jessica Meir made "HISTORY" as NASA is calling it, with the first #AllWomanSpacewalk.  Men aboard the International Space Station remained inside, as Koch & Meir went out to replace a broken battery charger. Media hi lighted it with caption: NASA astronauts Christina Koch & Jessica Meir made "HERstory,"
