Craig: i'm sorry. i laugh because canada is so far behind, and we're trying to play catch up. like, it's hilarious, but hopefully, we we overtake. but, so canada apparently has made some significant strides in nuclear fusion, not fission, which is currently out there. so, apparently, we're home to general fusion, which i've never heard of before. have you heard of it, craig?

Jon: no. not before reading up on this.

Craig: yeah. so it's a company that's pioneering the development of a unique sphere spherical tokamak design, which is the, reactor that a lot of other companies and countries are are using. so they're aiming to create and maintain the conditions necessary for nuclear fusion. but, their major milestone is gears behind others. they successfully compressed plasma within its reactor, which demonstrates its improved performance and stability. and yeah. so, like, they haven't even, they haven't even created a fusion reaction yet.

Jon: yeah. well, you know, we are trying to get to limitless energy and, you know, the potential to save our planet. so i don't expect it's gonna be fast. love the concept of spherical tokamaks. you know? they remind me of the tony stark's reactor.

Craig: yeah. the arc reactor.

Jon: yeah. that he created. thank you. but when it comes to fusion, it turns out a sphere has the upper hand. these compact devices use sophisticated magnetic fields to confine the plasma, the hot supercharged gas where nuclear fusion occurs. the spherical design not only stabilize plasma better than the traditional donut shape, but also packs a punch inefficiency. it's like upgrading from a chunky old flip phone to the latest smartphones. smaller, smarter, and and more powerful. now we talked last week or a couple of weeks ago on, three d printing your own or on do it yourself, fusion reactors, and i'm trying to remember the part, but it was the donut part we're talking about. yeah. so, i'm curious to see where this will line up in all of those. and is this truly a game changer? if we're talking about numbers in a world where space is at a premium, spherical tokamaks require significantly less room and resources compared to their larger predecessors. researchers are optimistic that this could lead to commercially viable fusion power within the next decade. yes, folks. that means potentially limitless clean energy as solar power farm on a sunny day in ten years.

Craig: yeah. so this is great, because i don't think we've covered canadian fusion developments before, have we?

Jon: no. i don't think so.

Craig: so yeah. so the couple things to note that i did some additional research. so, they've got some strategic planning in place. the cnl unveiled a road map for fusion energy for canada, so that's cool. although they are behind, they've got some private sector, which is general fusion. there's also some international collaboration that canada is doing with other countries. for instance, uk and canada have agreed on a joint research program to tackle the challenge of producing and processing tritium, which is a crucial fuel for fusion reactors. we also have, apparently, a strong foundation in nuclear technology with about fifteen percent of our electricity coming from luke nuclear power. and, apparently, the canadian government has shown support for nuclear technology. in the twenty twenty four budget, they reinforce the government support for the nuclear sector, recognizing it as a key tool, but i think there's more funding that needs to be, allocated to this because it's gonna cost billions to develop this. right?

Jon: yeah. we had talked a couple weeks ago about canada becoming a nuclear superpower with their upgraded, nuclear reactors, but we weren't talking about fusion at that time. we're gearing up interestingly. there's a flurry of local startups making waves and substantial investment in fusion technology. it's clear that you know, we're not just sitting on the sidelines. i don't know if we're gonna be able to catch up though. who knew that canada could be breeding a breeding ground for energy solution of tomorrow? you know? maple syrup hockey and now fusion energy. so, you know, let's not get ahead of ourselves. there's lots of challenges here, and like you said, we're behind. so it'll be interesting to see if we can leapfrog with some of these things. plasma instability, materials that can withstand the extreme conditions yeah. and the holy grail of funding to keep research on track. solving these puzzles is crucial to unlocking the potential of fusion energy. looking into crystal ball, the future energy production might just be a world where our homes are powered by fusion reactors smaller than our garages. these spherical tokamaks could help solve the energy crisis offering not just power, but cleaner, greener way to fuel our lives with virtually no waste and a nearly limitless fuel supply. fusion energy isn't just a dream. it's becoming a tangible reality. yeah. so what do you think? are severe cold tokamaks the key to sustainable energy feature, or is it just another scientific pipe dream? share your thoughts and predictions with us. is canada the next leader in fusion energy, or are we gonna go the way of the avro arrow? let's keep the conversation going.
