@WholeMarsBlog Not intentional! We just wanted to show that you could theoretically convert the entire US vehicle fleet to electric using only the lithium in Nevada, a single state. Tesla will do lithium mining only as needed. We also found a way to extract lithium using NaCl (table salt).

@Erdayastronaut Those engines could go 300 bar, but would be dicey. Pushing it for near-term tests doesn’t achieve anything, but I’m confident Raptor will do 300 bar for orbital flights.

@Erdayastronaut Raptor has now run for 90 secs at 300 bar chamber pressure before encountering issues. 210 mT-F sea level operating thrust seems achievable with no major changes. R-Boost variant is aiming for 300 ton thrust at 300 bar with same nozzle exit area. Will need bigger pumps.
