What Samo Burja is saying in this video is what worries me about some nuclear proponents: they seem to think if we just bet heavily on nuclear we can make 10x, 100x, even 1000x as much energy without any limits on growth. But thermal power plants actually contribute to global warming by directly heating the planet. The effect is surprisingly large. Within a couple of orders of magnitude of CO2 emissions. So if we’re talking about scaling up the use of thermal power plants by several orders of magnitude we’re going I have a problem. And they’re often dumping heat directly in rivers and shorelines, which is not ideal. I suspect to sustainably scale nuclear energy we will need to radiate their waste heat directly to space with thermal radiation panels. So essentially reverse solar power. But then you need a lot more area for these panels. It’s pretty clear that renewables will lead to an extreme abundance of energy. Check Tony Sebas presentation for some good projections. So I don’t see why we’d need all this nuclear anyway. Except for space of course. That’s one reason why I still support large investments in nuclear R&D (hedging our bets is another good reason)
