Future Island is back to look to the future in the worlds of science and technology.
Presenter Anna Daly will employ her curiosity for how things work and how science might make the future better for her children, embracing the "infinite possibilities" of science that are the theme of this year's Science Week.
Anna will be joined on the series by a panel of experts, among them Dr. Shane Bergin, physicist and Assistant Professor in Science Education at UCD’s School of Education, and Dr Jessamyn Fairfield, an American physicist who researches biocompatible nanomaterials and neuromorphic devices at University of Galway, and who is also a stand-up comedian.
The series will feature a mix of live studio guests and demonstrations, as well as a selection of illuminating films. It will sift the science fact from the science fiction and look at how Irish innovators are currently trying to change the world for the better.
Over three consecutive nights on RTÉ One, Future Island will examine innovations from all around the world, as well as profiling the work of Irish scientists Hamilton and Tyndall, who have left profound legacies.
Wednesday's episode took viewers on a trip to the Aran Islands (Inis Mór, Inis Meáin and Inis Oírr), which have a combined population of over 1,200 inhabitants.
For the last decade, the Aran islands have been upgrading buildings with more energy-efficient systems, with many of the islanders hoping to achieve energy autonomy.
A project in a collaboration between the Aran Islands Energy Co-op, University of Galway, ESB Networks and Údarás na Gaeltachta, has seen 300 buildings across the islands begin retrofitting including external wall insulations, heat pumps, and solar PV panels.
