Philip Johnston
Co-founder and CEO of Starcloud
“we've got an agreement with Crusoe where we essentially say to them, hey, we have a box, and that box has power cooling and connectivity and we'll work with you on whatever chip architecture you like... you pay that kind of rental fee to us and you finance the chips”
“we came to a launch cost break even around $500 a kilo if we had a cheap way to get the data center space”
“Our radiator design is 10 times less mass per watt of dissipation than the ISS radiator. And about 100 times less cost per watt of dissipation”
“we can fit about 50 of them per starship. So talking about about 10 megawatts of new compute capacity per starship launch”
“if you want to book anything for 2028 on Falcon 9, there's just nothing available. The government's just plonked down 20 launches which has bumped everything back”
“if you include energy and infrastructure, you're talking about at least 30% of the cost... to build a new energy project terrestrially, you're looking at like a 5 to 10 year long lead time on just the permitting”
“in 10 years I would say most new compute capacity will be on space... I would be surprised if more than half of all compute is in space in 20 years”
“The ideal altitude to fly is actually 1200 kilometers. That's the lowest you can fly where you don't have any blackout throughout the year”
“If you ask me do I think SpaceX has a monopoly in launch in 5 years, the answer is yes. In 10 years the answer is no”
“Starlink is going to produce hundreds of billions of dollars of free cash flow in the next sort of five to 10 years... I can't see a world where on Starlink revenues alone SpaceX isn't the most valuable company in the world”
