Sand is incredibly good at holding heat, so with proper insulation, the battery can hold heat for days to months without losing much. Long enough to convert that heat BACK into power and send it <br \/>to people all year round.<\/p>\n<p>The sand is not nearly as efficient compared to the lithium-ion batteries you\u2019re using in your phone. But it&#8217;s cheap, abundant, and sustainable. And could be a great way to deliver constant energy as we rely more on renewable energy sources.<\/p>\n<p>For more optimistic science and tech stories, subscribe!<\/p>\n<p>#shorts #sand #energy #heat #science<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is a battery made of sand.
