Do you hate shoveling the walk-way, porch or driveway as I do? My idea is to lay small heated coils under the concrete walk way or driveway. The coils will heat the concrete or pavement above freezing temperature and will prevent snow and ice from building up. Such a solution will save your time and money as well as save you from slipping and falling.

I want to have some device which can automatically test the pool for its chemicals and then fix them accordingly. It could be placed near the filter in my pool and should have a timer.

It would be really great to have sound filters for windows. They could work much like the mosquito nets. In case you fastened such a filter on the outside of your window it'd keep out all the street noise, but would let in the fresh air.

If you are tired of the same old boring wallpaper designs on your wall then you'll find my idea interesting. I suggest creating digital wallpaper. There would be digital paper or some kind of very thin screen on your wall. A small computer box would also be on the wall. You would be able to download any image you wanted to see on your walls. In such a way you could change wallpaper every day.

I want my house to repel heat in summer and absorb heat in winter. My idea is to create paint (or vinyl siding) that becomes darker when it is cold and lighter when it is warm. With such paint I would accomplish my goal.

I suggest using shower cabin as a dryer as well. There could be an additional tap with hot air added to the shower.

I am sure that those people, who are always losing their keys, will find this idea interesting. It would be awesome to have a fingerprint scanner right on a doorknob where a key hole was. You'd need to register your fingerprint on a microcomputer and then you would lock / unlock the door just putting your finger on the scanner.

I have heard stories of people, and even worse little children getting there fingers stuck in the door way. What we need are doors that are pinch free. Some sort of retractable mechanisms on the edges of doorways to prevent serious injuries that are caused everyday.

I'd like to have a wrist watch that could be set to alarm every 30 minutes, or every 2 hours, or whatever intervals were needed. It should vibrate but not sound in order not to disturb anybody and keep the reason of alarm private. The watch could be used as a reminder to take a medicine or do some exercises.

It would be really cool to have a pet door that responded to a collar on your pet's neck only. If another cat or dog tried to get in, the door wouldn't budge. If your pet couldn't stay inside because of the heat or simply wanted to do its business in the yard, it would be easy to get out and return.
