Hi Bill,
The concept was based on low cost turbo-machinery using production CNC
production methods. Small gas turbines examples used in R/C were included as
part of part of the study using CNC as well as additive/subtractive production
methods. The independent drive characteristics of the electric pump also had
potential advantages during transient operation such as startup etc.
Turbo-generators were also studied in these systems.
Best.

Anthony;
Interesting; I’ve seen prototypes of refuelable batteries that in some
incarnations appear to be tiny fuel cells but not of any true single use fuel
cells.
I take it the trade is for similar mass to a turbine but lower development
costs? Would you expect lower production costs as well? Turbines are hard to
develop (I tried once) but appear to have a big production rate effect when
using modern machine tools….

We worked briefly with a company that builds hydrogen fuel cells with the
notion of powering electric pumps for the FALCON program in 2004. I don't
recall the details, but if the fuel cells only had to run for a couple of
minutes (as well as the pump motors) the resulting conceptual package had the
potential to be mass competitive. One of the issues was volume and not
necessarily mass at the time. I don't know enough about fuel cell technology
or if the technology has evolved enough to make this feasible. Has the concept
of a low mass, single use, fuel cell has been demonstrated in the interim?

And as for rockets -- remember them? :-) -- electric and hydrogen have their
niches, especially in space. For ordinary launchers, though, sure looks like
LOX/hydrocarbon is the way to bet (with the caveat, again, that the
hydrocarbons might eventually be biofuels or synfuels).
