Power efficiency and radiation resilience

1:33:02looking up at the night sky and seeing, you know, >> Yeah. >> these giant floating radiators. >> Yeah. And and I I mean it it perhaps this is is going to be bad for astronomy, terrestrial astronomy, but there's there's got to be ways around it. I mean, it's already bad with the Starlink satellites that are up, but does that mean that like we don't provide internet to like these remote areas? Like, you know, technology and innovation comes at a cost, and we're just going to have to figure out ways to battle. >> And with the lower cost of payload, you could argue we could have a much larger array of space-based instrumentation. >> Exactly. >> That exist that negates the need to have terrestrial observatories. Again,

1:33:44there's some caveats there. >> There's a lot of caveats. A >> lot of caveats. Right. But that, you know, they're trade-offs and we'll have to continue to >> Yeah. Maybe we can make the orbits like avoid >> Chile, which is where like half of everything is, [laughter] right? >> If you just avoid like Hawaii and Chile, like half of the astronomers are going to be happy, right? >> You know, so um I mean that's going to be hard given that it's like high Earth orbit and whatever. But in any case, >> the the other thing that I want to bring up is this is not just an advantage in terms of cooling. Okay, there's two other things that this new memory technology would give us >> for data centers in space. One is the extreme power efficiency. I was talking

1:34:25about how it only takes like very little amount of voltage in order to do that computation with a memory. Now satellites operate on extremely strict power budgets. You can imagine right often it's under 20 watts and in standard AI chips nearly every single watt of electricity is consumed directly into heat but memoristers use this in-memory analog computing they don't have to do this von bottleneck right so if we're applying memoristers here then that complex mathematics instantaneously happens without shuttling the data back and forth >> now you're consuming a fraction of the power of a traditional GPU and that's going to bring down the amount of power

1:35:06that you need to dissipate again. >> So, this is both you can have the radiators be smaller and you can have the solar panels be smaller. >> Exactly. >> Because you don't need as much power intake. >> Exactly. Or with the same solar panels, you can do a lot more. Right. >> You know, either way, right? Efficiency is always great. >> Yeah. Yeah. >> Both in power dissipation and in terms of computing. And finally, the other big thing that people talk about with data centers in space is like normal GPUs, a cosmic ray comes in. >> Yeah. I don't know where that what if that bit was a zero or a one, right? Like what? So like a a galaxy decided to fart and then and then now like my AI query is giving me nonsense. That's not

1:35:47great, right? You need electronics that is able to sustain performance in a high radiation environment. >> Memoristers are great for this because memorist store memory by physically moving atoms and creating structural bridges, right? this like veilance charge mechanism rather than relying on these easily disrupted pockets of electrical charge. So now you can imagine a cosmic ray comes in, it's not really going to upset the veilance charge mechanism all that much compared to if there was a single like sort of point of failure, >> right? And so the there is the we have a >> thermal radiation benefit,

1:36:28>> a power efficiency benefit and a resilience benefit. And it's hard for me to imagine again there is the engineering problem but it's kind of like when Nvidia started with GPUs before you could really understand what the impact would be. We already can see now in the case of data centers in space why if you can figure out the industrial scaling of this >> it it it makes the execution of it in three the three arguably three of the most important categories yeah >> that you care about as an operator
