Five years ago today this was the top item on HN (http://news.ycombinator.com/item?id=55974):
Post novel startup ideas as comments and see how many karma points it receives. Who knows, one might be developed and you can take credit for thinking of the idea first.. It had some interesting ideas, some of which are solved or obsolete. Thought it might be fun to do this again.
(I run Wayback Letter, so that is how I know this odd bit of information - http://www.waybackletter.com/archive/daily/09-18-2012.html).
- Remote aid delivery by drone: build and send small robotic aircraft to remote areas and drop aid, preferably starting with medicine (lightweight and very useful). Small helicopters (quadrotor drone copters as you see at TED/MIT) could land and accept return packages if necessary. Trips could be made to hazardous places where human-driven aid drops can't venture. Additionally, all aid drops could be done cheaper and more efficiently. [The drones should be solar-powered?]
- Microwave oven with a solid, opaque door. On the door put a nice 1020p screen and inside put video cameras. You could microwave food, see a convincing video of it cook and not have to deal with harmful radiation or an unpleasant grilled screen.
- Pizza button. I had this idea about two years ago, someone in Dubai is currently executing (I think). You order a button, a physical red button (or an app with a big button, but that's not as cool). If you press the button, a pizza arrives at your location (tracked either by smartphone or by pre-set address). Default pizza arrives unless other instructions are set. I would insist on extreme simplicity: no options, no choices. Just "press button to receive pizza".
