Host cities always try to put their own special twist on things when it comes to designing Olympic medals. For Tokyo, that twist is to make them out of people’s old, unwanted gadgets.You’re probably well aware of the fact that electronics contain all kinds of valuable metals. The Olympic Committee is challenging Japanese residents to recycle eight tons of old electronics. They’re hopeful that amount will yield enough gold to produce the 5,000 medals they’ll need to award winners at both the Olympic and Paralympic games.They don’t need as much gold to make that many medals as you might thing. The gold medals handed out at the Rio games, for example, used roughly .2 ounces of gold. If they use a similar composition for Tokyo, they’ll only need about 62 pounds of gold.Image: WikipediaFormer Olympic decathlete and world-record holder Ashton Eaton told Japan Times, “when an athlete at Tokyo wins a medal, the weight of it will not be from the gold, silver or bronze; it will be the weight of a nation.” Medals made from recycled electronics already sound cool, but Eaton makes it sound downright badass.Mobile giant NTT Docomo will be placing collection boxes in 2400 of its stores, and organizers estimate that they’ll need millions of phones to hit their 8-ton goal. Other collection centers will be set up so that locals can drop off other electronics, too.Old motherboards and CPUs will no doubt be welcome contributions, especially older ones. Gold tended to be used a lot less sparingly back in the day of 386 and 486 PCs, so they’ll hit their goal a whole lot quicker if people have vintage computing hardware they can part with.
