Physical Data Security

Why a complete loss of trust in online security is the best thing that can happen to the modern world.

What's it made of? Part II: Supra-local Supermaterials

If more advanced technologies are available to reduce the cost of transport compared to the cost of extracting resources in the Solar System, it would be wise to consider a more general distribution of resources. 

Nuclear EFP and HEAT

A follow-up to the popular Casaba Howitzer post, we now look more closely at the concept of nuclear shaped charges in both Explosively Formed Projectile and High-Explosive Anti-Tank (Monroe effect) forms. 

What's it made of? Part I: Locally available materials

Little thought is given to the materials spaceships are made out of. In this post, we'll try to find out what are the likely materials being used, how the would affect the spaceship's design and extrapolate the effects of more advanced materials. 

Interstellar Trade is Possible Part III: Threats, Strategy and Evolution

Interstellar trade does not happen in a vacuum.

The colony will be face multiple threats, to be defended against as it evolves into a more and more significant part of human civilization.

Interstellar Trade Is Possible Part II: Travel

This is Part 2 of the series focusing on realistic Interstellar Trade. 

Here we will look at the various propulsion systems available and discuss which are appropriate in different settings and futures. 

Interstellar Trade Is Possible

In this post, we will detail a method for developing interstellar trade using near-future technologies and commercially realistic requirements. We will then look at the various outcomes, challenges and development models that will follow the first interstellar operation.

There is now a Summary at the end of the post.

Laser Launch into Orbit

In this post, we will look at laser launch systems, how they would look like and perform, and how they might be applied to reach orbit and beyond.

How to Live on Other Planets: Jupiter

A look at how we could colonize Jupiter and its Moon. Fittingly long for our largest planet!

Boosted Orbital Tether - a fishing line in space!

The Boosted Orbital Tether is a less extreme version of the space elevator. A rocket is launched on a vertical trajectory to an altitude of several hundred kilometres. An orbiting mass drags a line and hook to catch the rocket and spends momentum to bring the rocket into orbit.

Let's look at the concept in more detail.
