Tantalum is an rare metal with unique properties. Chief among these is that with a melting point of 2996 degrees Celsius, it's a superlative thermal conductor.

Almost two-thirds of the world's tantalum production ends up in high-quality capacitors that are used in devices such as mobile phones and other electronic gadgets.

Only trace quantities are used in each device with a typical Nokia mobile phone, for instance, containing about 40 milligrams of the stuff. But being the golden age of gadgetry, tantalum should be in high demand.

      NelsonG posted a topic in General News,

      You could have been forgiven for missing the announcement that actual physical Burning Man has been canceled for this year, if not next. Firstly, the nonprofit Burning Man organization, known affectionately to insiders as the Borg, posted it after 5 p.m. PT Friday. That, even in the COVID-19 era, is the traditional time to push out news when you don't want much media attention. 
      But secondly, you may have missed its cancellation because the Borg is being careful not to use the C-word. The announcement was neutrally titled "The Burning Man Multiverse in 2020." Even as it offers refunds to early ticket buyers, considers layoffs and other belt-tightening measures, and can't even commit to a physical event in 2021, the Borg is making lemonade by focusing on an online-only version of Black Rock City this coming August.    Read more...
