Yeah, I mean, as I mentioned, we're able we look at the overall climate tech investment thesis, we have a lot of CO2 to decarbonize. And we have wind and solar that doing pretty well, in the past decade, the cost of solar has dropped 90%. But we still have to figure out you know, the land, you need to put it on, the fact that it's intermittent. So there needs to be something else that would provide the best load so that you can finally shut down a coal fired power plant. And there's not a lot of things out there. You can look at hydro, geothermal, but those are geographically limited. Fission is producing a lot of radioactive waste. So we were like, okay, we need to look at fusion, but we weren't sure if this would be close to getting to the grid or not. So we did the landscape scan of the fusion. And I would say that the approach wise, you have three main different category: one is the magnetic confinement fusion, which is mimicking the sun, you try to bring the hydrogen closer together with the gravity force for the sun, and then once it's get close enough, then it fuse and then you release a lot of energy. And then another approach is the laser fusion, where you have the fuel pellets. And then you try to compress the atom together by you use the laser to heat up the shell of the pellet. And then it's an implosion, it just fuse the atom together, it has short bursts of energy tons. And then the third category is something in between, it's called magneto-inertial fusion. Some company try to do the so-called Z-pinch approach, which mimic how you got the lightning through the rod. And once you have the current flowing through it generate the magnetic field that compress and can generate and can compress the atom together and generate fusion energy. We looked at all of these and we found that there are perhaps four reactor configuration that is very close to the energy breakeven which is the energy out compared to the energy in. So far to fuse the atom to get it generate energy, it costs a lot of penalty on the energy that you have to force the fuel together. And the four technology that is close to the breakeven is the tokamak, the stellarator, the laser, and then the MagLIF, which is one of the variation of the Z-pinch approach. And there are several labs that has been looking at things in the US. If you're looking at the tokamak, MIT has a center, the UK has the JET, the Joint European Torus, they've been doing amazing work in terms of generating the energy. And there's international consortium that has put together the biggest tokamak called the ITER Project in France, that 20 billion project that has been under construction for two decades and still not done. And unfortunately, it was built upon the old technology, low temperature superconductor. So and then you start seeing a private company, Commonwealth Fusion Systems that is going to build a spark project here in Massachusetts, with the high temperature superconductor, and prove that you can take the magnetic confinement fusion in the tokamak configuration to net gain. So it's exciting that we'll see something like this in the US. And for the stellarator, we talk about the world's largest project, in Germany, W7-X: that's a very exciting project, and they are gonna be able to show that you are going to be able to really hold the fusion condition for 30 minutes. So when you talk to them about tokamak, when you talk about laser, those are post-process, once you show that it's getting to the net gain, you have figure out how to become a continuous power generation plan. But I think that W7-X will how that you can have a new reactor configuration that can actually generate and hold steady state for what period of time. And then for the laser, the NIF, the National Ignition Facility at Lawrence Livermore National Labs, they have a very famous record, scientific energy gain experiment around Christmas last year. So that's the place where you can find a novel and breakthrough laser approach. And then the the XEP page approach that you have several facility, there's a Sandia National Labs that are doing the experiment on the magLIF. And there are a number of private fusion company that's looking at the technology in this area as well. So it's very vibrant communities, you'll find a lot of private fusion at startup. I think there are more than 40 private fusion startup companies, right now, so.
