This week, we travel from Scotland to space to find out. First, host Derek Burrows welcomes Vicky Coy, the Head of Innovation Projects at Catapult in Glasgow, where they specialize in offshore renewables. Vicky talks about the testing of tidal power and how we can learn from the old to create the new. Then, we launch into space with David Poston, the Chief Technical Officer of Space Nuclear Power Corporation. David breaks down what it’s really like to put nuclear reactors into space, and why good testing is just as much about the doing as it is the dreaming and talking.
