Air cooling shirt. Backpacking in warm weather, I often pause and wet my shirt in a stream. The evaporative cooling as it dries is wonderful. So if a shirt had little water "tanks" around the shoulders, a shirt might be kept wet and keep cooling for hours, perhaps. They might need to be lightweight, and they'd have to release the lake slowly. Better still would be tanks having an adjustable rate of flow, so that you might have the shirt wetted at the same minute rates are was drying.
Motorskimobile. It is a motorcycle for snow. It might run using a track just like a snowmobile, nevertheless it will be a different of ride. The consumer will be sitting higher, much like on the motorcycle, and would be able to maneuver tighter turns. It might also drop narrow trails quicker.
Wave generators. As kids, we roped, chained and tried everything we might think about to maintain our raft anchored. If the waves came, though, perhaps the chains broke. Why don't you use this lifting energy the waves to perform generators? The complete unit could be anchored to the bottom of the lake, or ocean. A float would progress up and down with all the waves, lifting and dropping a plunger that turns generators with each and every movement. Additional units might be easily added to a collection, as well as the resulting electricity wired to shore.
Caskets for possessions. A novelty invention, the concept here is to get something to bury your preferred possessions in when they're broken or otherwise "dead."
A wall that changes colors. You might have perhaps seen those billboards which use three-sided rotating panels to right away alter the picture about the sign. There are three possible views, obviously. The newest idea here is to use this invention to walls for houses. When you get uninterested in along with of the wall, you push some control and it changes to a different color, or even a mural, or whichever from the three choices you determine it up with.
Paintings that change. This is the same concept as the above invention. It is simply scaled as a result of a frame that will display any of three prints using the push of your mouse.
Disposable picnic backpacks. They are plastic, sufficiently strong during their visit use, and come with the snacks and bottle water already in them. Purchase one for every with the kids prior to deciding to hit the hiking trail.
Chip dip tubes. No more messy bowls of stale, drying chip dip with broken chips in it. Instead, you just apply the dip from your toothpaste-like tube, directly on the chip. You obtain the proper amount, with less mess. They are often purchased from six packs, so everyone is able to have their own tube. Hmm... What else can be put in tubes? What size if the tubes be? Here is a concept ripe for some new invention ideas.
