Post Availability of HTP?   Posted on: Mon Jun 16, 2008 3:07 pm
Anyone out there using HTP, where do you get it, and what is it costing you?

Thanks

Post HTP availability, cost   Posted on: Mon Jun 16, 2008 3:48 pm
James: 1st, hello from a fellow N Prize entrant.

I've found HTP is very expensive (up to 8 US dollars/pound) and difficult to get--some I know of have to have it shipped from Sweden.

A little facetiuos perhaps, but I recommend using hydrogen-free HTP, ie LOX. The Microlauncher based entry will, as has all Microlauncher designs.

There aren't any real problems with handling LOX in small quantities. Present insulators are very good

Post HTP vs LOX   Posted on: Mon Jun 16, 2008 4:28 pm
Thanks Charles. I expected it to be expensive. I see one aspect of the N-Prize as the use of well understood, well developed technologies, which are usually cheaper as well. LOX handling, storage and usage is one of those.

Thanks

The article "Indian Probe Catches X-Rays From Moon" ( http://www.space.com/scienceastronomy/0 ... flare.html ) mentions
Quote:
But the signal was clear enough to spot traces of magnesium, aluminum and silicon making up the lunar region


So there obviously is aluminum on the Moon.

I would have to look for the other ingredients of HTPB but it might be that such lunar ressources might enable to get HTPB a bit cheaper perhaps if it is produced there since its price wouldn't be ruled by earthian markets at present.

Vehicles launching from the Moon might become autonomous to some degree and deliver to other vehicles and locations in space.



What about it?

A superficial investigation indicates there are substantial parts of both Carbon and Hydrogen in HTPB, both of which are potentially scarce on the moon.

But.. isn't HTPB quite off-topic, since HTP aka peroxide is a completely unrelated fuel?

Hello, Minthos,

think of Richard Speck's idea of hydrogen farming by thin films of Titan

This easyly would solve the hydrogen problem. The carbon can be broght from elsewhere - it may be possible at reasonable costs (as my calculations in the Financial Barriers section suggest that I will continue once I have sufficient time again).
