And so for the first two months of the company, that was literally what we're doing.
We were called Lumen Orbit because of that reason, luminosity in orbit.
We were thinking, okay, once we get that power down, what are we going to be using it for?
And even back in 23, most new energy projects were being built for data centers.
So we were like, okay, well, either directly or indirectly, this power is going to go into data centers.
Let's rerun those numbers.
So initially we'd run the numbers to know what's the launch cost breakeven that makes sense for space-based solar.
And we'd come to a number of like $50 a kilo.
So then we read around the calculations.
We were like, OK, let's spend a month figuring out what would the launch cost breakeven need to be to make data centers in space breakeven.
And we came to a much closer to reality number of $500 a kilo.
And that's what we think currently that the breakeven launch cost is.
And so then we rapidly pivoted the company towards that.
Yeah, I mean, it was incredible.
So just to tell people a bit about StarCloud One.
So we'd set this launch date, you know, 18 months in the future.
And we initially started with something quite unimpressive.
Like we were going to fly some NVIDIA jets and chips, they've been flown in space before, and we're going to try and do some new new workloads on there.
So it was Addy that came on and said, no, we need to do something way, way cooler than that.
And we actually ended up putting five GPUs on there, three from NVIDIA, two from ARM.
