"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?

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.
