Say you are in a huge hall or a big class and 50 fans are running. You want to switch off one fan. How do you do that?? As of now, we switch off one, wait for some time till decrease in speed is noticeable and if luck is urs, that is the correct fan, otherwise, keep iterating. Rather, there should be a bank of LEDs on the perimeter of the rim. So we just keep looking at our fan of interest, keep toggling all switches. When LEDs of the fan of interest go blind, done!!

Commercial Channel, a channel where they have something about commercial 24/7. -Old commercials -New ones -Commercial talk-show -Commercial Interviews -Comeercial Buzz and games -Hystory of brands -etc. Preety much like MTV, but commercial is the word instead of music.

A mini projector built into a cellphone can display whatever is supposed to be displayed on the cellphone screen. When you combine this and that keyboard that can be used to write stuff on the cellphone it gets really comfortable.

This is a simple motion control/capture device to be retrofit over any TV (can be programmed) which allows the user to control the tv using simple hand gestures. For example wave up for volume up, down for volume down. Wave right for channel up, left for channel down. Great for couch potatoes. Can easilly be made with technology available today.

A box that only unlocks when you blow into a(n) attached/detached breathalyzer. This would let someone take all the keys of party guests and know who to let drive when they leave easily!

This is out of reach of my personal techno savvy, but would one of you young geniuses please invent a pop-up blocker for TELEVISION. Here in the States, on cable TV, our screens are constantly bombarded with pop-ups that are annoying and interrupt the show. Most of them are ads for up-coming shows and they tend to show up either in the corner of the screen or across the bottom. Can they be blocked as are internet pop-ups?

Where are my glasses? Why can't I have a very small device with a hook (or other means of attachment) on it to put on my glasses, on my palm pilot, on my car keys, on my bottle of beer, etc. that will emit a shrill sound or flash a light after I dial some numbers on my cell phone?

I would like to see a real three dimensional TV. Like an aquarium, filled with some kind of liquid, that can be controlled to display the "image". When watching, it will be like watching a mini theatre!

Set sensors over head of the house garage door and/or ceiling so that you will always park the car in desired place. Never hit the side mirror on garage and leave space for other car. The sensor could be a (laser) light and linked to the door opener. If the car is not driven in from the right place and parked in right place the sound warning will be issued.

Create a cell network whereby each cell phone "forwards" the call to the recipient. Example: I am location A and want to speak to my friend in location B, X miles away, let's say 10 miles. I call him/her and the cell phone transmission hops and skips through other users' idle phones until it finds my friend. Network would take advantage of users whose phones are idle - on, but not in use - to transmit and amplify the calls. Each cell phone is connected to the network and is standing...
