Check out Rob Walling. He's got some podcasts and grown to some conferences now, but i keep going back to his book: Start Small, Stay Small: A Developer's Guide to Launching a Startup
Edit: just looked it up but see also Rob's new project TinySeed.com: The First Startup Accelerator Designed for Bootstrappers.
I'd say they cant produce a low enough signature with the nacelles on the bottom as currently displayed. see all aircraft in this nasa clip from April 2018.
Decoding the Universe: How the New Science of Information Is Explaining Everything in the Cosmos, from Our Brains to Black Holes, by Charles Seife
One item discussed in the book that we as humans may just be a transport method for the data within DNA to survive time. Because without some replication it would get trapped and cease to exist.
note too a replay solution could have infinite steps to have to reproduce, assuming its not optimized to take any shortcuts to jump to a re-occurring state.
i cant wait to see the testing videos here. think Boston Dynamics kicking their machine and pushing them downstairs. There better be billions of dollars in destroyed airframes ahead of any human cargo.
I'd start with a mentally forced mashup for each to get a few that might work. e.g. "If i've got to make money by lead generation with a medical bill review service/app, how could i do it?"
Then i'd focus on how we'd drive value to the consumers.
Then think about driving value to others parties who may be willing to pay for something similar.
ie would pharmaceutical and medical device companies be willing to communicate directly with these consumers?
note i'm not saying its easy by any means, but i do think its a real problem that could take off if an elegant and worthwhile solution came about.
