Free-standing tents without poles: The idea here is to have two inflatable sleeves that criss-cross over the top of a dome-style tent. Perhaps the rigidity would be insufficient for windy nights, but it's worth a try. Make them inflatable from
Rail-runner bicycle attachment: This is a
Kites inflated with helium: If its been done, I haven't seen them yet. With some lift from the helium, these kites could be flown in any amount of wind. Designed right, they would still fly something like a kite, and with more maneuverability if designed like a stunt kite, with two strings. The first prototype might be a kite with a small helium balloon attached. If somebody makes this, I'll buy one.
Other New Inventions
Disposable t-shirts:
Fast-food tube: These could be like the tubes at bank drive-throughs, but they would have to stay level for the sake of the drinks. Using these, one slow person won't hold up the whole line at the drive-through, because there can be several lines. The customers send money in through this conveyor system, and get food back the same way. Just pull up to whichever lane is empty. I'm waiting to see this invention.
Magnetic painting kits: This new novelty invention would consist of a flat "canvas" of magnetic material (steel?), and an assortment of many colors of iron dust or small shavings. Just apply the metal dust carefully to create any "painting" you can imagine. It would be something like a Buddhist sand mandala, but slightly more permanent. Spray the finished painting with a "fixer," and you could even hang it on the wall.
Invisible walls: This is a new invention that would be just plain fun. Make a wall with properly placed cameras, using the other side of the wall was the projection screen for these cameras, and the effect would be that of looking right into the other room - an invisible wall. I'm not sure about the practical applications, but an "invisible ceiling" would provide a nice view at night.
Magnetic signs for windows: Thousands of businesses use large magnetic signs for their vehicles, with their company name and logo on them. Of course these can only be used on metallic surfaces. To stick to car or building windows, they need a similar flat magnet or steel mesh material that is placed on the other side of the glass, to hold them in place. This may be one of those "unpatentable" ideas, but the first to trademark a catchy name and market them widely might do well with new inventions like these.
