"I wonder why you wrote your email instead of letting Michael do that himself,
your business silo companion."
Because you were so off base.
" An abandoned ICBM silo enterprise eh, like the Breeds on this list."
Are you insulting Paul Breed?
" My question regarded only (about to correct me if I was wrong) that no
amateur ever was capable to launch a kerosene-peroxide bipropellant rocket."
No amateur has put something in orbit either. Should we dismiss orbital
missions because amateurs have not done it?
" A pity you..."
How ironic.
" A pity you mentioned the Beal days 1997-2000. Michael's enrichment plant for
Beal, sort of an amateur design scale-up did not perform as expected at
MacGregor (Texas) and was torn down. Got bad press at the time. You may note XL
Space Systems business went away the whole time Beal was in operation: reported
on this list on 09022013. "
XL Space Systems went away because Michael decided to work directly for Beal.
As for "bad press", do I have to remind you of all the negative arm chair
commentaries about SpaceX when they started? The point I was making was that
Michael Carden made a huge amount of hydrogen peroxide for Beal and it did
work. Note the many pictures on the web of the enormous 810,000 lbf engine
firing using hydrogen peroxide and kerosene.
" Banker entrepreneur Beal ceased rocket ops in Texas (MacGregor). Oops, 200
dismissed: scandal then! We later read Beal was not allowed to build launch
pads abroad (ESA was), did not get along well with NASA (contrary to SpaceX
much later). Beal's impressive huge carbon fiber engines disassembled somewhat
prematurely. Maybe they combusted."
So you are criticizing Michael because his employer had issues with NASA and
decided to close shop? How many private space companies have had to close shop
for various reasons? Do you dismiss them?
And what does any of this have to do with XL Space?
" Maybe a good idea to use a sparger to produce amateur hydrogen peroxide. Not
so for industry: they all use vacuum distillation, at least up to 85 %."
Keep in mind that big companies like FMC have integrated plants that make many
more chemicals then just hydrogen peroxide. This affects the design of the
plant and may use excess chemicals produced in other operations.
XL Space produces above 85%, the most being 90%. He also produces 100%
anhydrous hydrogen peroxide using a different process. Where else can you buy
that?
To be blunt, why should a customer care about the method of production if the
product meets specs?
" Now it seems FMC does sell peroxide to amateurs: well not to Armadillo and
that is why they abandoned peroxide as a propellant. A pity after so much
experience gathered."
If they wouldn't sell to Armadillo, why would they sell to any other amateur
group? FMC gave Armadillo the run around saying that they would sell to them
*if* they only made a few safety changes at their shop. Carmack made the
changes and then FMC wanted more changes. After a while Carmack realized they
were just messing with him and would not sell to them.
You can deal with FMC if you want. Call up XL Space and you will actually get
hydrogen peroxide.
" But this "green" liquid is sneaky & can cause horrible detonations and fires.
I know what I am talking about, like several on this list. Even those who have
"stellar" HP knowledge can still get blown up to... the stars with it. A wrong
brand of flange containing some catalyst and boom the concentrator goes."
Do we really have to go down the list of accidents with all different kinds of
propellants? "safe" nitrous oxide detonates on occasion and I do not see a lot
of disparaging remarks against amateurs using it.
It is the nature of rocket propellants that they contain a lot of energy, or
else they would not be good rocket propellants. If you are looking for
something *completely safe* please inform us.
