Why not build a house that uses ground and snow as isolation? The house could have 3 sloped sides going to ground level and there if it is helpful could be roof covered air pockets between underground wall and ground. One side would be mostly glass. During winter the snow would help insulate most of the building (as there are no walls except the glass wall letting light and warmth in). Rainwater could be collected and used (by dehydration) in summer to cool the building. Air would need...

Having read about deaths occurring due to people extending ladders past the safe extension point I felt there had to be an answer. My idea is that the last rungs of the ladder have an extra extrusion on the back of the rung thus stopping the extended front part of the ladder from being located on the last rungs. This would stop people from overstretching the ladder thus avoiding a collapse due to undue stresses. An after market kit could also be sold as it would be quite a simple...

Do you change your wallpaper every month or so? Are you tired of the same old boring wallpaper designs on your wall? Changing the wallpaper can be really hard too. The digital wallpaper could change that. it would be digital paper or some kind of very thin screen that would fit on your walls. A small computer box that would also be on the wall would be able to download any image or pattern you want and put it on the digital paper or screen so you could change wallpaper every day if you...

The bladeless ceiling fan creates an indoor breeze that's smoother and quieter--and safer for cats. The fan features a stack of spinning discs that take advantage of the science of laminar flow to move air throughout the room. The air is directed around the room in a 360° horizontal flow, moving with a smooth, uninterrupted stream and mixing the air in the room to eliminate hot or cold spots.

After a tired day at work it is very refreshing to enter ur living room and step on the doormat which releases aroma of flowers etc.The doormat should consist of pressure sensitive modules which release aroma when stepped on. Can be named aromats.

People in sunny countries living on top floors with sun blazing their roof experience harshness of summer all their lives. If the top floor roof is made of two slabs i.e. one cheaper and another stronger (for terrace) on top of it with no walls between them for air circulation, then those people will live a cooler life. This idea can be used by builders for selling their top floors at proper rates.

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.

Have you ever dealed with hanging picture frames on the walls? I bet you have. You need to do your measurments, make sure it is straight and then screw a hole in the wall to hang the frame. How about creating picture frames with magnets at the back that can be attached to the wall without any hassle? When you want to take them off the wall, you will have no scars on the wall. But we need a specific wall paper that has fine lines of iron in it. I think it is a great idea for builders which...

Being a teacher, I find that my classroom is too crowded with lab tables to maneuver (16 lab tables for 32 students). I think I should be able to make use of the vertical room space with bunk desks. We could seat belt the students in up top.

A vest containing a compressed helium cylinder with a deploying balloon. Microprocessor controlled valving to adjust gas volume to slow the descent of a person forced to jump from a highrise building. This device could also be used to lift survivors just above frigid or shark infested waters until rescue arrives.
