Ideaexplore

Here's a strange but potentially useful site: Ideaexplore. Its a collection of ideas (ie. new ways of doing things, ways to solve common problems, new business ideas). Anyone can submit an idea, and anyone can use the idea freely without obligation.

Here are 4 ideas from the site that I like:
==
A disturbing noise (sound) can be eliminated if it is taken through a microphone, shifted 180 degrees out of phase electronically, amplified and played with an audio speaker. May also be sold as a toy "Cone of Silence" to absorb anything you say.

Road Rollers are too heavy for moving from one site to another. A lightweight but strong & high-power roller can use a tank of water or sand to increase its weight & capacity at site. The same road roller can be used for various weight categories.

My college's Disability Resource Center scans in and auto-converts books to Braille, but math/economics/chemistry books must be entered by hand because the scanning software can't "read" the formulas. Software capable of this would be immensely helpful.

In flood-prone areas, build high-rise flats/condominiums instead of single-family homes so that the homes will stay dry in floods. Build parks on the remaining land.
