    The only actual metric they quoted is exhaust speed?

    Not saying we shouldn’t be skeptical, but isn’t that the most important metric? A crazy-high exhaust velocity is how you get an engine with crazy-high specific impulse.

      I would argue that fuel consumption would be quite important, same with power usage.

      Edit: and also exhaust mass. If it’s 1g of mass exhausted then it’s a moot point.
