Oil lamps are still widely used in spite of the fact that they are toxic and not environmentally safe. My idea is to use solar lamps instead of oil lamps. Solar lamps work 6 hours and above; they are available for all people who don't have reliable source of electricity. Solar lamps have changeable solar batteries which are environment-friendly as they are recyclable. Lamps have brightness regulator, they are water- and heat-resistant and can even be used below -4 °F and above 131°F.

My idea is to create a service which will provide elderly people with extra conveniences for living in their houses, i.e. suggest design changes to make their life easier. For example, kitchens could have contrasting worktops to improve visual orientation; mixer taps are recommended to have one handle; there could be extra handrails in a bathroom as well as a seat in a shower, etc. Highly skilled specialists will inspect the house and advice many design ideas for you to make your...

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.

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.

Individual plastic molded photochromic roof tiles that can replace original concrete tiles. Each tile interlinks with the next just like normal but has a hot shoe connection embedded in the tile. The energy collected from the roof can be supplied to a battery storage area and converted to household electricity via an inverter. The amount of electricity gathered would be greater than solar panels as you would have the whole roof acting as a giant SOLAR PANEL.
