Use-that-other-wall gadget Printer Friendly Version
There's this big fat wall sitting in front of my kitchen window (it's probably the same wall you have in front of your toilet window, or someone else can see from his sleeping room window).
"My" wall is only a couple of feet away from the kitchen window, but it's far enough so I can't touch it when I lean out of the window (and I wouldn't want to try it as Im living on the fourth floor). Still the wall really looks like I should make some cool use of it. If the wall was made of steel, I could use huge magnets and put my shopping lists up there (just like other people do on their fridge doors). Technically I could always write down the shopping list on a piece of paper, stick it in a beamer and project it against the wall, but that's not really the convenience I'm looking for (also it would constantly use up energy). So what I need is a cool idea how I can use that "other" wall which isn't my property and where I'm not allowed to use screws or nails.

Clog Resistant Drain Printer Friendly Version
Street drains, like those in your kitchen sink, are designed to let water and small amounts of solid matter pass through. Beyond that, they will clog. Their design demand it.
How about street drains with gradual "convex" rises instead of straight bars. They would be strongly built to withstand cars and trucks. Leaves, paper, and other debris would shed from the top of the drain and sucked to the lowest open areas. Water, blocked by the forming debris at the base would be forced to seek a "higher" level toward the top of the drain and through.
Yes, this drain would also eventually clog, but not with moderate amounts of debris.

Flat 3D Screen Printer Friendly Version
I was just thinking about the future of Flat Screen TV's. Understanding that more screens are being made out of plastic emulsions gave me an interesting idea.
Most of us understand the concept of a LCD clock that you see through. Well if you filled the clock with color dots this would create a very thin color TV. About the size and weight of two pieces of paper. The problem is it would have to work one-hundred percent of the time. Otherwise you would begin to see through the screen.
3D: Now place a 20 or 30 screens, behind that screen. Not a redundancy system, but a 3D system. Pictures would transfer themselves from screen to screen. Pictures would seem to jump forth just like in the movies, but without the glasses. Way Cool!
Reward: Product of course, and a state of the art sound system; 7.1, and a vibrating couch.
