Such new inventions that I would like to see happen in the future.

 Do you want to create new inventions that make money? I do not. I just like making them up. Here are some of the new ideas I'd like to see come to fruition.

New inventions for the outdoors

Poleless Free-Standing Tents: The idea is to have two inflatable sleeves that cross over the top of the dome tent. Perhaps the stiffness would be insufficient for windy nights, but it's worth a try.

Make them inflatable on the inside and you can quickly crawl in and out of the rain to inflate them.

Rail-runner wheel attachment: This is a new invention that I want to try, but it will not be popular with railway companies. Wouldn't it be great to be able to ride a bike on rails? They go to many places where roads do not lead.

The idea here is a device that keeps the bicycle wheels on track while you pedal. Easy removal would be necessary, of course, for the occasional passing train.

Helium-Inflated Dragons: If it happened, I haven't seen it yet. With some buoyancy from helium, these kites could be flown in any wind.

Designed correctly, they would still fly somewhat like a kite and with more maneuverability if designed as a two-string stunt kite. The first prototype could be a kite with a small helium balloon attached.

Other new inventions

Disposable t-shirts: Dollar stores have t-shirts on their shelves, so we know they're still cheap. Why didn't he invent a line of shirts that are low quality but good enough and cost very little to make?  Where is the market? Those who want less laundry on long trips, or those who want some cheap stuff to wear when doing dirty work.

Fast food tube: This could be like the test tubes at the bank drive-thru, but they would have to stay horizontal for drinks. Using them, one slow person won't hold up the entire line at the drive-thru, as there may be multiple lines.

Customers send money through this conveyor system and receive food back similarly. Just drive into any lane that is empty.

Magnetic Painting Kits: This new invention would consist of a flat "canvas" of magnetic material (steel?) and an assortment of many colors of iron dust or small shavings. Just carefully apply metallic dust to create any "painting" you can imagine.

It would be something like a Buddhist sand mandala, but a bit more permanent. Spray the finished painting with a "fixer" and you can even hang it on the wall.

Invisible Walls: This is a new invention that would just be fun. Make a wall with properly placed cameras, using the other side of the wall as a projection screen for those cameras and the effect would be that you are looking directly into the other room - an invisible wall. I'm not sure of the practical applications, but an "invisible ceiling" would provide a nice view at night.

Magnetic Window Signs: Thousands of businesses use large magnetic signs for their vehicles with their company name and logo. Of course, they can only be used on metal surfaces.

To stick to cars or building windows, they need a similar flat magnet or steel mesh that is placed on the other side of the glass to hold them in place. This may be one of those "unpatentable" ideas, but whoever gets a catchy name and sells it widely first could do well with new inventions like these.
