Contribute Interesting Ideas

I will post ideas here that you send me; selectively, of course.  For a list of topics, look at the "Welcome to" box above.  In particular, send me ideas for things that you think have been breakthroughs and tell me why you think they qualify. Requirement: transforms an industry, changes people’s habits, or makes something new available not available before, and that people want.  Also, read my book, Breakthroughs!, which you can download free at this website.
