@vincent13031925 This engine needs to be 10X lower cost. Order of magnitude change is good reason for a new name. What really matters is not yet another “advanced” rocket engine, as there are many such devices, but there has never been a cheap (<$1000/Ton-force) rocket engine. Not even close— Elon Musk (@elonmusk)

@SamTwits @Erdayastronaut @PPathole @vincent13031925 Long chain hydrocarbons, like kerosene, have excellent volumetric energy density, but what you really want for rockets is best way to bind hydrogen, which is CH4. Also, easy to make & store CH4+O2 from CO2+H2O, which are abundant on Mars.— Elon Musk (@elonmusk)
