This book provides an extremely mathematicalized treatment of novel light-sails.
These light-sails are proposed to have many modes of additional propulsion as well as being able to access a wide variety of artificial and natural fuel and energy sources present in the background.
Light-sails even in their most basic forms have a fascinating appeal in that they are in a kind of “neither here nor there” class of spacecraft propulsion systems.
For example, they require little or no onboard power sources in that they extract their energy from the radiant background of space. Even almost all warp-drive and wormhole concepts assume onboard or proximate energy sources and then so to extreme levels.
Yet light-sails in their basic forms do not rely on rocket exhaust but are driven merely by incident light.
Although highly mathematical, this book has plenty of prose to delight those without an advanced mathematics background. Thus, this book can serve as an analog of the Rosetta Stone for those new to the field of relativistic astronautics.
