There’s a new book out by Michael Carroll, covering possible earthlike worlds around other stars, and how we might reach them.
And several of my images are in there, in the advanced propulsion sections! I’ve not got very far into it yet, but so far it’s impressive, and the artwork is very nicely printed.
It’s here on amazon UK: https://www.amazon.co.uk/Earths-Distant-Suns-Communicate-Travel/dp/3319439634
And here on Amazon USA: https://www.amazon.com/Earths-Distant-Suns-Communicate-Travel/dp/3319439634
Amongst the images used are several of my Nuclear Pulse Orion, Daedalus interstellar, and my visualisation of a Bussard Ramjet.
He was also kind enough to put a personal thank you note into my copy!
