Judge for yourself whether these business ideas have a future:
PizzaBot: An app-driven service that delivers pizza assembled and baked in self-driving trucks.
Trashnado: An app to request on-demand garbage pickup instead of waiting once a week.
Pray It Forward: An online "marketplace" for group prayer.
Those are just three of the nearly two dozen business ideas posted on a San Francisco startup named IdeaMarket, which bills itself as a virtual crowdsourced business incubator.
