What's an idea bank? Does it generate interest?

Whynot.net is an idea bank.

In general they generates curiousity. If they generates enough curiousity then that curiousity is spent on activity. If the activity is successful then we have a new product/process/etc... that makes the world a slightly easier place to live in.

There are lots of idea banks out there, they just lack a central access point.

Although there are undoubtedly many interesting and practical ideas expressed here there are also a very large contingent of almost total idiocies involving a lack of understanding of the basic principles of elementary physics. This site is amusing but I frankly doubt it is a fount of overwhelming energy for revolutionary innovation. The source there would probably be people actively investigating basic research in new materials and novel techniques. If nothing else, the proper sorting of practical ideas and separating out those that even have faint commercial possibilities borders on the classical problem of getting something worthwhile from 50 million monkeys randomly punching at 50 million word processors.
