I’ve been looking for a “drop in” window. What I mean is a window requiring a hole in the wall which would not require cutting of the exterior wall studs. (outside dimensions less than 14 1/2" Any manufacturer will be happy to make one (very expensive and many other sizes are available off the shelf at Home Depot etc. Seems like H.D. could make a killing offering these in different heights with sliders, louvres etc. Could be installed by a homeowner in an hour or so.
Who else has an invention for someone else to invent?
Re: Why doesn’t someone invent this
Probably because it would be far too easy for an overzealous homeowner to saw through water or gas pipes, or electrical wiring if he did it himself. 
Inventions that would be cool, if I knew how to invent them.
A video game with a totally interactive environment. Not a text based game either, a game with graphics and such. See a wall, you can blow up the wall. Do to much damage to a building and the building collapses. Realistic weapons physics too.
A Video conference system that has tele-remote Waldos. This would enable people to have a form of physical contact with the people they are conferencing with.
A liquid that is slowly absorbed into the digestive system that contains all the nutrients and assorted stuff you need for a full day. Drink the drink in the AM, and not get hungry again all day. The perfect diet aid, and handy for emergencies.
A fridge with a clear door, so that you can see the items inside.
A birth control pill for men.
A Pop-Tart transport capsule, so you can put your morning Pop-Tart in your briefcase and not have it smashed by the time you make it to the office. :mad:
Benanuel, I’d like a word in private with you…
Pssst…Benanuel, C’mere…Tupperware. All shapes and sizes and available in your local grocery or WalMart…We’ll just keep this between us so it doesn’t go flying off the shelves before you get a chance to get some ok? 
So as I was saying, Benanuel , I’m sorry for your smashed pop-tart pain.
They’ll never suspect a thing
That’s actually not a bad idea, then we would be able to tell whether the light really does go off when the door is shut.
Of course if the light did go off when the door is closed, a transparent door would be of little value.
Of course if one of thoes clever engineer fellows thought to put a push button on the door so you could turn on the light for the duration of your “browse” and then let go of the button and it would go off…
I’d buy one!
What I think would sell would be a 30ft long hose that attaches to your vacum cleaner, at the end of the hose is a hard plastic comb with which to groom your dog with.
The point of the long hose is so you could leave the vacum in the bedroom whilst hoovering the dog in the kitchen.
that way the dog wont be terrified by the screaming noise the vacum makes.
These exist. They kinda suck because there’s no in-door storage, so you have to reach past more stuff to get to the things in the back.
Plus, you have to clean your refrigerator before you have guests over.
Ah, the problem with thinking of something useful is that you never think of the downsides… 
Now all we need is clear food, to put in the doors!
I’ve brought this up before but I really want it so I’m bringing it up again.
One-shot entire-house vacuum. Everything in the house has to be securely fastened to an immovable object. Family, including pet, leaves the house. Master or Mistress of the house presses remote control button, entire house is vacuumed. Standing dust, dog hair, dirt, all gone.
It’s an idea whose time has come.
You mean noboby has installed a webcam on the inside of their refrigerator?
The whole house vacum thing just doesn’t sit right for me, what about ornaments? Would I have to take time out to sellotape small figures to the televison? I have a ceramic dish that is full of pennies, would I have to put cling-film over the top of that , as well as blu-tacking the dish to the table?
The solution to this would just have a light you could turn on and off from the outside of the refrigerator. As for the doors being transparent, I don’t know if the cold could be retained as easily.
I agree with Ethilrist in that a refrigerator with a transparent door would require keeping it clean and tidied up when guests were visiting.
I think there’s room for plenty of inventions for cars. I think we’ve all dreamed about having a message board that flips up on the roof of our cars with bright LED lights that could display messages for other drivers (I’m sure I don’t need to provide specific examples of suggested messages to use). For drivers in front of you the board could revserse the letters so the driver could see the message in his rearview mirror 
I remember my sister telling me about devices which will automatically mute your TV/stereo whenever the phone rings, but I have ever seen such a device. I’m sure something like this would be easy to make.
Bang Olofsen has that feature integrated with their audio-visual and telephone stuff. Cost’s a bomb, but their stuff is really, really good. The volume goes down when the phone rings, and then if you like, you can raise it some more or lower it entirely or pause or whatever from your phone handset when you have answered the call.
They’re called “space shuttles.” Kinda spendy, though.
These are already available.
Cite, Mangetout?
MajorTom, your one hour estimate probably doesn’t include the installation of headers and footers for your narrow window. You’d have to bash out the surrounding plaster to access a point where you could nail them in. Just repairing the plaster, taping, painting, etc. is about. an hour.
I do like the idea tho. I picture a hole wall of narrow windows, it would be kinda cool.
Andersen will make custom windows to size, so it has already been “invented”. What I suspect you mean is, why aren’t the readily available.
