For areas in the world that suffer from frozen and icy roads. Tyres for cars are consumables, they wear out, and the rubber "dust" gets inbedded in and on the road. My idea is to make the rubber act as a de-icer for the roads. A chemical of some type would need to be added to the rubber to...

a similar idea, but for police and speed cameras. When people see a police car or a camera, you press a button, which could include direction of travel e.t.c. This info is updated to a data base and then download by radar detectors in peoples cars. Trends could be developed as to where police spend ...

I hate getting parking tickets, so I sat down and thought of a way to get around it. When the parking wardens come round, they mark the front tyre closest to the curb with a chalk mark. On their next round, if the chalk mark is still there then they dish out a ticket. A modified automatic fragance d...

if you were going to have a digital display on the tip of the snow board, why not add a few more features like speed, barometer e.t.c. This could be done via gps. The unit could be charged via solar powered.

...do it your self, open it up and wire in a 3.5mm socket to the speaker or the phone. It should work, try it on an old phone

This could be done with bluetooth. Some Digital cameras and video camera have bluetooth. All you would then need is a bluetooth enabled GPS and some clever software.

The skin friction, excuse the pun, between the needle's metalic surface and the tissue would be next to nothing. You only feel needle as it penertrates the skin, not when it is traveling through the tissue. Adding teflon to the needles surface would also increase the diameter of the needle some what...

why not add an indicator to the milk (non toxic dye that changes colour with changing pH). It would go green when the milk changes it's pH level. All would be needed then would be a small clear window in the milk container. when the milk is green don't use it.

After burning countless bags of pop corn in the microwave, i thought that there must be a better method of timing the cooking time. A microphone would be placed in the microwave. During the first minute or so of operation, the microphone would pick up the ambient noise and set this as a base line. I...

put a snail in the tank.

yes i do realise that it would cost a lot of money to produce this concept presently. New technology lcd technology is currently being researched where the display can be printed on to a surface, just like ink. With this technology the concept would be economically vaiable, as the cost for printing ...

The same ultra violet rays that cause cancer also cause you to tan....

i used to have one of those described tooth brushes, i got it given to me about 6 years ago. it is sold as a travel toothbrush.

this is a really good idea, but if people don't look at the date on the carton of milk, what makes you think that they are going to look at a small piece of ltimus paper at the bottom of the carton?

I have a friend doing a physics project on ring lasers at the moment. A ring laser is made up of a two lasers and four mirrors. The lasers go in opposite dirrections in a square pattern. By measuring the interference between the laser beams, accelerations can be measured. This is roughly how they wo...
