Der 15-jährige Angelo Casimiro von den Philippinen hat eine Schuhsohle erfunden, die mithilfe piezoelektrischer Materialien bei jedem Schritt Strom erzeugt.
Damit lassen sich kleine USB-Geräte wie Handys nachhaltig aufladen – besonders praktisch für abgelegene Regionen ohne Stromversorgung. Casimiro hat das Design als Open Source veröffentlicht und plant, es künftig um GPS-Funktionen für Wanderer zu erweitern.
Seine Erfindung brachte ihm einen Platz als regionaler Finalist bei der Google Science Fair 2014 ein.

"The argument from Telegram is, 'You should trust us because we tell you that we're trustworthy,'" Maréchal said. "It's really in the eye of the beholder whether that's something you want to buy into." The fake Zelenskiy account reached 20,000 followers on Telegram before it was shut down, a remedial action that experts say is all too rare. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations. The picture was mixed overseas. Hong Kong’s Hang Seng Index fell 1.6%, under pressure from U.S. regulatory scrutiny on New York-listed Chinese companies. Stocks were more buoyant in Europe, where Frankfurt’s DAX surged 1.4%.
