We have an energy crisis, and it's not the one you think. To move to a more sustainable future we need to figure out how to power mass electrification, and source and store energy responsibly.   Scientists around the world are working on fascinating battery technologies to help, and Ireland is no exception. For example, Dr Valeria Nico is a postdoctoral research fellow in the area of energy harvesting at the Bernal Institute, University of Limerick, and she told us all about her work developing tech that can generate energy for small devices from vibrations in their environment.   It's powerful stuff, so get ready to strap yourself in and feel the Gs!    Read more about Valeria's work, the EU's new battery rules, and Codema's project to heat homes with waste energy from data centres on SiliconRepublic.com: https://www.siliconrepublic.com/machines/good-vibrations-developing-new-tech-for-energy-harvesting https://www.siliconrepublic.com/innovation/eu-batteries-sustainable-european-green-deal https://www.siliconrepublic.com/innovation/codema-equinix-waste-data-centre-heat-project-dublin   This episode of For Tech’s Sake was hosted by Elaine Burke and Jenny Darmody, and brought to you by Silicon Republic and The HeadStuff Podcast Network.
