Forget AI and 5G, it’s low-tech solutions that will help our planet


It’s a popular idea that the path to sustainability lies in high-tech solutions. By making everyday items like cars electric, and installing smart systems to monitor and reduce energy use, it seems we’ll still be able to enjoy the comforts to which we’ve become accustomed while doing our bit for the planet – a state known as “green growth”. But the risks of this approach are becoming ever clearer. Many modern technologies use materials like copper, cobalt, lithium and rare earth elements.

However, Swiss startup Transmutex wants to reinvent nuclear energy using a lesser-known element called thorium.  Uranium’s forgotten cousin Thorium is a lead-like metal that is mildly reactive, but four times more abundant than uranium and a lot safer to handle. However, thorium is a fissionable material but not a… This story continues at The Next Web from The Next Web https://ift.tt/ideQqVM
