On this episode energy systems expert James Fleay joins Nate to talk about the current state of nuclear energy and its potential applications in the future. Out of all the potential ‘replacements’ for the subsidy of the fossil labor force we’ve grown used to, nuclear energy is one of the most frequently suggested as being the savior of our modern lifestyles. What is the reality of the benefits and costs of nuclear energy? How does it fit into our current mix and our financial situation? Does it have the ability to support ‘human flourishing’ for millenia to come? Will the expansion of it result in a toxic waste situation that we can’t come back from? Or is nuclear energy simply one more piece to the puzzle for complex societies to support – and eventually reduce – their energy demands?
About James Fleay
James Fleay is an Australian engineer and energy project manager with two decades of experience in design, delivery, operation, and carbon sequestration in the power, oil, and natural gas sectors. Ten years ago, he joined the oil and gas sector to work on the design, delivery and operation of some of Australia’s largest complex energy (LNG) projects. This included 2 years work on one of the largest carbon capture and sequestration projects in the world and another 3 years on a ground-breaking deep-water subsea compression gas project in Australia’s North West. He is the founder and manager of DUNE, Down Under Nuclear Energy, with the purpose of studying the investment case for nuclear energy in Australia and understanding the parameters for its success.
In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President
That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher
We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF
This is the crux of the whole problem. Individual parts of nature are more valuable than the biocomplexity of nature. Thomas Crowther Founder Restor
