The growing costs of economical problems....and five basic (still in progress) business ideas...

Now where to begin....
Today is the day/post/assignment/"I have no choice but to do this" where I must place down five business ideas.

First thought to enter the head is simply a "what?"

Honestly, where to begin? When an idea is placed in the head that says, "okay there...think of five good ideas for business." It's hard to not feel left out to dry up. Business is a difficult thing. First of all I have to think, what classifies? An idea? An invention?....or a service?
Secondly...of course. There is an issue of cost. How do I know I'm not biting off more than I can chew? It's not like I have some relative that is rich and might have me in their will, so I can be around when a terrible accident happens.
So where ca I go from there? Something cheap, or something free to start up at....and to hopefully gain some profit to benefit people.

After a few long....procrastinated moments. An idea came.
Online of course.
Why it is a massive resource that is usually free (minus a rising monthly fee for it).

Soon ideas came.
The first had to do with some massive online database, similar to an online mall. While ideally it would be used as a cellphone application that could pinpoint your location from the phone to find nearby stores to find the product you're searching for, without having to go to many different shops to only be left disapointed.
For a second idea, kinda stretching on the same idea, an online application would be used, preferably an application for a cellphone, but instead of shops...it would be used for restaurants. The application would find nearby eateries and offer price ranges to meet budgets, reviews, contact information for restaurants (which, if using a phone, you could contact them instantly), and hours of operation.
The third idea that hit my head was something for mobile transportation. I followed onto a recently relative problem that I had to deal with, for this solution. I was recently in a car accident, where the driver totaled my car in the process. Now because I had insurance I was offered a rental car, but most kids/students my age would be left without transportation in such a situation. Their only option would be bus or walk. To most people that's not an option. So the service I would offer would be some sort of rental service aimed for a younger audience, for transportation. The catch would be cheaper vehicles, not meant for highway, mostly city related vehicles, such as mopeds or smart cars.
Fourth idea is for my passion of travel, an online resource to offer students to travel without fear, but in comfort. It would be an application that could be used on the computer or phone, that could allow students to tour/study abroad with an online course, enabling the high costs that most studying abroad ensure, allowing students to pick their own flights and to view and appreciate things at their own enjoyment. It would also be available for others to use as a touring device that would not include the lessons, assignments, or tests that students would have to enlist in.
Finally, because I was thirsty in-class, the last idea would be an in-home installed, rain-water filter. Attached to the roof of a home, the filter would collect pure and clean rainwater and deliver it into a storage system that could would be connected to the house. Primarily the water would be used for drinking purposes but if enough is stored, then it could be used for other purposes like bathing and for dish washers and cloth washers.

.....and that's about it.
The End.

The "what were they thinking?.....no really." ideals in life.

Look at this image....no, seriously. Look at it. Tell me the first thing in your head isn't some interjection like "WHAT?!?" Tell me you don't get slightly upset, or laugh, and then get upset again, and then go punch some random person in the street.....or is that just me?
With all honesty though, someone actually thought this was a good idea. Why?
In what way could this fit a line of success? Did someone think that having a cell phone in their pocket was such an inconvenience that they decided to strap a collar around the neck and add a pocket there for convenience? If business plans are meant to fall into two categories; operational plans, and plans designed to attract investors, then where does this fit in?
Dear Lord. (this isn't a rhetorical question by the way, someone please answer this)

True. Inventions and entrepreneurship are two completely different things, but they are also very similar. Inventors create things in mind in order for their creations to complete a service, just like entrepreneurship (however, skills and favors and tools are in mind versus a strait unified object).
But through this absurdity, can this even dare to be called an invention? The idea of such a thing as a "neck fanny pack" causes me to cringe and wake up in night sweats.
To put it straight, I am glad, even if it was a once thought of creation, it was not a successful one. The original fanny pack was bad enough.
