Might many of these already exist? But failed to get traction? There's no shortage of ideas. The questions are: - Is there a market? - Can you get traction in that market? - If you do, can you be profitable? - Will there be competition? And how will that influence the above? But raw ideas? Are those The Problem? I'd imagine you'd be better off looking in the graveyard of failed startups and look for poor exacution and/or poor timimg (i.e., market / tech was there just yet). At least then you have something to work with.
