"Correct me if I'm wrong."

You are wrong.

First off, Michael Carden's plant is not out in the desert, it is here in our
facilities in Wyoming.

Second, he is in near full production and is considering building another
sparger to increase production. We have recently concluded a 20 test campaign
for a customer using hydrogen peroxide. Just because YOU have not spoken to any
of his customers does not mean that they do not exist.

Thirdly, Carden's reliability is exceptional. In the several years that he has
been here I do not remember a single customer that has said that he was not
reliable. Yes, XL must make the hydrogen peroxide, so customers cannot expect
to buy 2000 lbm and have it shipped overnight; they have to get in line.
Despite this, I have personally seen Michael spend more than three days at a
time, 24 hours a day, here in our facilities making the hydrogen peroxide as
fast as he can in order to please customers. Carden's knowledge on hydrogen
peroxide is stellar. He reliably produced all the peroxide that Beal Aerospace
used. Considering that Beal developed and fired an 810,000 lbf thrust rocket
that is a lot of hydrogen peroxide.

Fourthly, just because Bengtsson's plant had a fire does not mean that hydrogen
peroxide should be abandoned as a propellant, which you are insinuating. How
many fires have other propellants produced?

Never heard of anybody buying from Michael. He has a big sparger mini plant in
the desert but I wonder if XL-Space is a reliable manufacturer.
Bengtsson 's HTP plant in Sweden OTOH, supplying jetpack enthusiasts in Europe
for many years never recovered after the 2010 fire.

Lastly, I know of no amateur team ever succeeding in launching a British style
kerosine/HTP bipropellant rocket. I said rocket and in the West. Takes so many
years and so much money to build all gave up. Correct me if I'm wrong.

Just curious. I remember former Armadillo gave up on 80-90 % peroxide
as a propellant because they reported that unexpectedly, they found no
more supplier. As considerable batches were required for their tests
and launches, they had wisely decided to avoid the hassle to distill
it themselves. Realizing such a mini plant of their own for it takes
years to design from scratch and build.
Big companies "responsible care" policy prohibits selling HTP to
rocket amateurs. So where do you buy or intend to buy your HTP at present,
Robert?
Monroe?

One thing your going to have to be prepared for, at least with using
silver as the catalyst, in my experience no two runs are exactly the
same. There is a little bit of an art in getting a clean run and with
silver, temperature, RH and even barometric pressure can play a role in
getting a good clean run.
