Hi, I wrote a book (The Captain's Glasses) which is set in After Oil era.
It has loads of ideas on alternative energy (e.g. compost showers, biodigestors, gasifiers to name but some) and agriculture incorporated in the story.
It's about an old man who lives with his daughter and her family in the house he built with all these of-the-grid ideas (there is no "grid" anymore...)
How do I go about promoting it?
