Generating business ideas- please help? - generating new business ideas

I try to find business ideas, so that I can dismiss without pity (sarcasm. ..). My background in biotechnology / nanotechnology and research, but I want to keep a eye on the horizon gap. To facilitate this, a few questions! Respond as you want, the questions there is only the exchange of ideas.

1. If you could fly and dethrone the market for companies there (Google?) What would it be?

2. What companies seem hard to start (railway)?

3. What will business and industry are supported by most of the world / is the company? Which industries are some cool?

4. What do you think of the next technology transfer that has revolutionized the world? What companies have big tailwind?

5. Name-billion dollar growth markets?

6. I do not know?

Thank you for your comments.
