Imagine that you walk into a supermarket where the prices for the products were all digitally displayed right under the product instead of the paper sticker. It would display it like a watch. It could easily be updated if there was a price change through a computer. There would be no need to have someone printing tickets and walking around looking for it to change the sticker. Products that aren't updated would have to sell for the actual price displayed if customer gets mad.

Forgive me if this is waffle but this idea came into my head so clearly the other night that I had to put it out there. I propose an extrusion process for data cable using an alloy of copper, gold and something like hematite or other semiconductor. The alloy is extruded as a cable through a die with an array of point sources for sound around its circumference this array is tuned to create a standing wave within it. Similar to the waves created by Alexander Lauterwasser. The goal...

This can work for any kind of charger, or transformer. Using the proper circuitry the charger turns off the transformer in order to radically diminish the consumption of energy when there is no device connected to it. How many chargers do you have constantly connected to the wall waisting electricity. All chargers by law should have this capability.

Nokia have barcode technology available for their phones, however I have researched its usage which is fairly limited. My idea would be for the likes of large brand name mobile companies to work in conjunction with large retail food outlets i.e. Wallmart(ASDA), Tesco. A bluetooth signal could run in the store which will be picked up by customers' mobiles on entering the shop. As well as showing special offers it could open the access to their database of barcodes for all of its products...

Ok... there should be some way we can recharge a cell phone without electricity. We should make a way to charge it the same way they have the flash lights u shake to make electricity. But we should put a similar device in a cell phone in case you're stranded with a dead battery, and need to make an emergancy call. But any ways it's just an idea...

Make a cell phone that you can sit down and it has a built in scale that will weigh up to an ounce. Should be relatively simple to make and there would definitley be a market for it.

As a wheelchair user I love lifts but I can't reach the buttons - especially the ones at the top... I think it wouldn't be difficult to make a remote control like for TV to allow me to type the floor number I need (or alarm button etc.) and send it to a receiver built into the panel. Buttons would operate as normal for those who don't need the remote. This might also help visually impaired as they could have a braille or voice activated remote. People who need the remote could buy one...

I would appreciate if we can connect Alphanumeric keypad with speaker to the phone so that a mute person can hear and type a text to talk, this text will be then voice synthesized and then passed over to the speaker of the person on other side.

Be able to power your lamps and other electrical things without a power cord. One main machine sends electricity harmlessly through the air, and whenever you turn something on that has a receiver, it pulls the electricity from the air. You never have to deal with cords again!
