1- 3D printing, (production with "atoms") and
2- social fundraising
such business are unlikely be as easy to start. They would require access to substantially more funds and manufacturing equipment.
Edit: They try to tie the social fundraising in to the "atoms" theme by referencing electrons, but it falls a bit flat.
I think equally cool is this project to start the first avocado farm in Iran: http://www.kickstarter.com/projects/943051402/irans-first-av...
It's far, far, far from its $10k goal. Is the problem that people care more about a plastic dongle versus avocados? Or that marketing at the end of the is the difference maker in making differences in the world?
The dongle people only need people interested in buying something that they benefit from.
