Question: Planning on writing a picture sci-fi book about Utopia.
The book will not have a plot (story), sequence or any conclusion. It will have approximately 30 illustrations generally depicting a search for Utopia, accompanied by minimal text for each illustration. Similar to a photo book.
Has anything similar to this been published before?
Could this spur sufficient interest?

Answer: 
*The Room* is about a man whose love life runs off the rails and ends in a brutal break-up. This is a topic that a *lot* of people are interested in. *La La Land* is about the same theme. *Shrek* seems like that's how it's going to end leading into the final act. I can't begin to list how many breakup songs have hit the top 10 charts.

The reason people don't like *The Room* isn't because the premise of the story is bad. It's because the movie was poorly executed. Honestly, you can probably make a story about any premise you want to. Would you be interested in reading a book about someone learning how to work at a post office? Apparently a lot of people would, because Terry Prachet's novel *Going Postal* is held in high regard. Would you read a book about a bunch of rich, stupid twenty-somethings going to Spain and getting drunk all the time? That's the plot to *The Sun Also Rises*, a cultural touchstone written by Ernest Hemingway. Heck, you can describe *The Room* as being about a spoiled rich guy who has awful relationships and then dies, and that's also the synopsis of *The Great Gatsby*.

Don't worry too much about whether your premise is workable. I contend you can make a good story out of literally any premise. What determines whether people will read your story or not is how well you've executed on your idea. So practice writing a lot, make multiple editing passes on your story, join a writing group, ask friends who can give honest critiques to read your work - do whatever it takes to be certain that your writing is solid, and your story will come alive.
What is interesting to the reader completely depends on the reader (the targeted and reached audience). For instance, people at a library will like different kind of books than people commuting by train.

The only way to know if people find your book interesting is to let people read your book (or parts of it, and then hope it represents the full quality of your book).
Let 10 people rate your book (chapter) on a scale from 0 = most boring stuff I've ever read to 10 = most interesting I've ever read. Let 10 other people rate a book with a similar amount of pages. Don't disclose which is your book. Then perform a T-test between the two groups.

If you're targeting a wide audience use popular narrative techniques. You might look at popular recently publicized books for techniques and constructs.

If you're targeting a niche audience, use in-group language and technical terms. Communicating with an in-group language that is understood by the reader gives a sense of belongingness.

If target audience is only one person writing an interesting book is the easiest. When there are 2 or more persons there will always be disagreement.
