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

Upward Bound: Getting into Space

In this episode we examine the concept of a Space Elevator, a popular piece of developing technology designed to lift people and cargo into space at a fraction of normal launch costs. We will look at technology as well as many of the misconceptions about Space Elevators which have emerged.

Upward Bound: Space Elevators

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

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

The Launch Loop is a type of space vehicle launch assist mechanism that allows us to transfer vast amounts of energy and  momentum from ground based generators to a launch vehicle high in the upper atmosphere.

Launch Loops

Today we look at using Space Towers, Buoyant Structures, Airships, and Space Fountains as means of launching spaceships, as well as their other applications to create enormous structures that normal materials could never permit.

Space Towers

The Orbital Ring is a type of launch-assist system that goes beyond moving small ships and crews into space and allows cheap movement of bulk cargo up to space, into orbit, and beyond.

Orbital Rings

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.
