This week in engineering and design brings you a great video on the absurdity of detecting gravitational waves, the future of wireless charging via your flat screen, and 3D printing helping to ID homicide victim.
This week we discovered the flat-screens TV on our living room walls could soon be remotely charging any device within its line of sight. (Not our actual TV, but a device that is similar in size and shape.) Researchers demonstrated that the technology already exists to produce a wireless power transfer system similar to a flat-screen TV that could remotely charge any device within its line of sight. The proposed system would be able to automatically and continuously charge any device anywhere within a room, making dead batteries a thing of the past.
Also this week we discovered some big names in the tech, including LinkedIn founder Reid Hoffman and eBay founder Pierre Omidyar (through his Omidyar Network), aren’t just fretting over the possibility of dangerous AI, they’re taking steps to make sure it doesn’t happen. Investing a total of $20 million into a newly created Ethics and Governance of Artificial Intelligence Fund, the two are hoping to fuel research into the social considerations around AI. The organization wants to be sure that machines aren’t just guided by the engineers designing them and the corporations funding them, but that they should also consider the input of everyone from social scientists through to economists and politicians.
3D PRINTING NEWS
This week we learned that thanks to 3D printing, the body of a woman found in Ohio has been identified. Ohio Bureau of Criminal Investigation used 3D printing to help solve a case involving a woman who had been found in Ohio’s Greene County in early 2016. The state of the body, coupled with a lack of leads and evidence, meant that the woman could not be identified. As a last resort, the bureau turned to a forensic artist who attempted to recreate the face of the woman using a 3D printed replica of her skull. Coupled with a DNA sample from the woman’s family, a suspect is being charged with her murder.
More news in 3D printing came from MIT this week where a group of researchers recently carried out some exciting experiments with graphene, considered to be the strongest of materials in 2D form. Translating that 2D strength into useful 3D materials has been difficult, but these researchers have created a new 3D material with 5% the density and ten times the strength of steel, making it one of the strongest light weight materials known.
VIDEO OF THE WEEK
A lot of videos have covered the general overview of the discovery of gravitational waves, what they are, the history of the search, when they were found, but this week we found Veritasium who wanted to delve into the absurd science that made the detection possible.
