Just started listening to Podcasts, so I've some catching up to do, Thanks Isaac.

An in-depth survey of the various technologies for spaceship propulsion, both from those we can expect to see in a few years and those at the edge of theoretical science. We'll break them down to basics and familiarize ourselves with the concepts.
Note: I made a rather large math error about the Force per Power the EmDrive exerts at 32:10, initial tentative results for thrust are a good deal higher than I calculated compared to a flashlight

The Spaceship Propulsion Compendium

In this episode we begin our look at possible Alien Civilizations by considering the impossible ones. Fiction has introduced a lot of misconceptions about aliens we need to clear away before we can seriously consider them and that begins by looking at some of the common ideas and removing any that rely on the concept of advanced civilization being quite stupid.

Stupid Aliens

We continue our look at hypothetical alien civilizations by discussing the various possible circumstances in which we might first contact them or be contacted by them.

First Contact

In this episode we continue our look at possible Alien Civilizations by attempting to peer into the alien psyche. In the absence of any actual ones to examine we will review fictional examples and try to match those up against both human behavior and what we might consider likely, unlikely, or impossible to arise from evolutionary processes.

Upward Bound: Getting into Space

In this episode we examine the Skyhooks and Rotovators, technology designed to lift grab spaceplanes or rockets at far slower speeds than normal and lift them into space at a fraction of normal launch costs.

Upward Bound: Skyhooks

This episode feature Mass Drivers, Space Guns, and other means of rapidly accelerating a spaceship up to orbital speeds without a rocket. We will explore the basic concepts, the engineering issues, and the potential cost & safety advantages & disadvantages along with how these devices can be used in tandem with other systems we have looked at.

Mass Drivers

Continuing our look at possible alien civilizations, we examine extinct alien civilizations and the possibly of finding them and exploring their ruins to learn about them. We will also contemplate the possibility of bringing them back, and the conundrums that raises.

Dead Aliens

In this episode we'll be looking at improvements to rocket systems, with the main focus on re-usability. We will also look a bit deeper at rocketry principles, at some other improvements and alternative uses for rockets, such as oceanic launches, and discuss Metallic Hydrogen, a potential game changing fuel.

Reusable Rockets

While potentially dangerous, nuclear powered spacecraft offer far faster and more efficient spacecraft than traditional chemical rockets. Today we will examine the various means of using atomic power sources to propel spacecraft, bot to get off Earth and to travel to other stars.

The Nuclear Option

Episode 144: Power Satellites - How transmitting power down from space may be our future.
Visit our sponsor: https://skl.sh/isaac2
Beaming energy down from satellites in orbit to replace the production of electricity on Earth may solve many of our problems, and avoid a potential economic or ecological crisis such as energy bottlenecks or global warming. Today we will explore how wireless microwave transmission of energy down to rectennas may not only be possible, but could be massively profitable in the near future and spur our exploration and colonization of space.
