Just like storm windows, a double pipe can keep the weather out, but PVC and steel pipes break in the winter even when they are insulated if they are single pipes. I have seen that pipes of any kind (plastic, steel, copper, etc.) used in any application come in any size you want them in. If you have a one inch pipe then you place the hardly useable insulation over it tightly, then you place a slightly larger pipe over it which provides a pocket of air around the inner pipe which will never...

A transmitter attached to your car can be programed to control your house if your within proximity. Example: I programed mine to turn on some lights, the air conditioner and sprinklers.

Let us take a look at this vision. A larger door handle but moved to the centre of the door where a lock mechanism will push iron pins into three sides of the frame (the top and both sides). The pins are hidden inside the door and the lock could be formed to push each pin simutaneously(sp?)into guard plates inserted into the door frame.

Here's what I would love if someone would create... Christmas lights that can be left up all year without making you look like the problem neighbor. I'm thinking of a thin housing or tube that blends seamlessly with the gutters on your house. The housing would appear white when the lights were off, but would be transparent enough to see the lights through when they were turned on. Of course, the lights would have to be reliable so you don't lose strings here and there and have to climb...

People who stay in apartments/houses/anywhere with boring, depressing or even ugly views through their windows, will benefit from this. A tranquill forest scene or a sandy beach with the usual scenery, there are millions of suitable pictures. Place these pics: Size to extend past window's edges, in an advertising sign board type of frame. Attach this to the wall outside the window, so that the view from inside is now the picture you chose. What if you get bored with that picture? Well...

Every house has a fridge and a freezer and alot have air conditioners which are all basic heat exchangers (warm to cold or freezing) well there are now heat exchangers for heating homes (cold to warm) usually in-floor heating as well as hot water tanks, well I was thinking that a house should be built so that all forms of heat exchange are intergrated into one system

Window screens that filter the air would be a wonderful invention, especially for us allergy sufferers. It shouldn't be too hard and we could all benefit from cleaner air!

We could use adding more uniqueness and character to our homes and add that to our address. We could set up a real National Paid Directory of house addresses and there names with each name different from any other. We now name stars and boats so, why not our homes?! We could get really creative and it could reflect our families personalities or the house or anything you can imagine from any real or made up word or short sentence ever spoken from time immortal in any language you choose. It...

A periscope type of insert for your chimney that projects real time view of the sky, or chimney top vista, to a screen at the fire place opening. A sort of Rube Goldberg version of the window.

Robotics that can build 3d dimensional building structures in the oceans using nutrients and materials from the ocean. For example, if you could make floating algae bricks, or Coral Bricks and robotically place and combine them. The inspection, maintenance and repair should be fully robotic/automatic also.
