The Hydrogen Fallacy

Posted 01-31-2012 at 01:19 AM by T.Neo

(For the TL:DR version, scroll down to the bottom of the post.)

It is the position, or opinion of some (such as the writer of this blog post) that liquid hydrogen/oxygen ('hydrolox') rocket engines are a poor choice for first stages of launch vehicles, because they are 'thrust limited' and/or have a lower engine T/W.

However, there is no intrinsic correlation between thrust and propellant combination. If you had the motivation, resources and time, you could theoretically...

WIP Starship (read: Giant Cone)

Here it is so far:



My first 3D model and first completely original Orbiter...thing. It'll get better. I hope.

In the mean time, I'm in the middle of the idea phase. Here's what I want it to do, at least for now:

1. Be capable of interstellar and interplanetary flight using magical antimatter whatever engines (MAWEs.) Accelerates nominally at ~10m/s^2.

SEP-008 Chapter 2

"Matt, what happened up there?"

The gruff voice resonated off of the office wall, and Flight Director Matthew Payton grimaced as all of his possibly intelligent answers flew out the window. Standing where he was for a moment in a fleeting state of complete apoplexy, he sighed and approached the desk.

"We're still working on it, Ed."

"Good,"...

Minecraft Portal map development

Posted 01-27-2012 at 08:36 PM by Samuel Edwards

Greetings all,

Since this is not a minecraft forum, I posted this to my blog so to not cause a ruckus in the main forum.

I am creating a minecraft Portal map to use with the Portal Gun mod for minecraft. So far it has come along quite well, and I have developed a few test chambers to get started. I will post more and add pictures as the project develops. You may not see pics and blogs on this project often as it is a personal project that I am doing in my spare...

This is something I'm throwing out for some trivial entertainment. I've had my run of 'huh!' moments where I'll come back to a scenario on Orbiter and find the spacecraft I was piloting embroiled in an unusual situation, or behaving oddly (on one occasion I found my intrepid XR5 landed on the surface of Oberon from LEO).

So without further ado, in the spirit of complete geekery, and just to show off my meager writing skills, I give you:

SEP-008, Chapter 1.
