The Idea Shop

Hey everybody, on a more serious note than the $20 auction, does anybody have any ideas for entrepeneurship? There is something on the 15th at Northwestern University called Entrepreneur Idol where winner gets a 25k 10% investment to start up their idea...at UofI. So, if you come up with one, you will definitely be included in the project although possibly not in the presentation/pitch of the idea on the 15th. But we must also come up with well-rounded teams to show to the sponsors that their 10% commitment is worth it. So please just brainstorm and bounce ideas around. Here are a few of mine.

New Plane "Seats"-
Background:
Airplane seats are heavy, they give you not much leg room and they are terribly annoying to sleep in.
Invention:
A light weight board like structure that shapes itself to your body. It is vertical during the plane ride and you strap yourself in, so instead of sitting, you're standing but with not much weight on your legs. Instead, your weight will be supported by things both under your armpit and legs (need help on other ideas to support weight of standing/slightly reclined person). The "seats" or "stands" shall also be positioned back to back so that you have maximum room between you and the next person, although you will be looking at someone the whole ride. The extra people that can fit into the middle aisles mean that some of the sides can be left open. Here I propose things that will hold these stands horizontally, that are attached to the walls. Essentially, when you get tired, you will attach your board to the wall and climb up into your new bunk bed. Benefits are that you have more legroom during the ride and more comfy i think, because you won't feel really weak after your trip, and you can actually lay out in economy class.

Swimming Start Helper-
Background:
There are tens of thousands of swim teams all across the world. Add that up and there are easily a few million club (mostly pre-highschool), highschool and college swimmers along with the countless millions who swim recreationally. As a swim coach, the most time taking skill, yet a skill that is crucial for competitive swimming and just looking like you know how to swim...is the start. Learning to not belly-flop takes most swimmers about 3-4 years to develop and at least 100+ hours average. It also unfortunately often takes individual coaching to develop since most of the problems come from confidence and it is difficult to pause and think in the half second it takes to enter the water.
Invention:
So, I propose a pair of rails that will allow a person to be suspended (after they jump off the block) and moved forward (by ball bearings on the rail and a harness around the person) and into the water. The shape of the track guides the person through the path and feeling of a correct start. A biiig benefit is being able to feel the actual speed that a real start should feel like. Similar object can be created for divers who (if you add more friction) can go through their diving procedures in slow motion, and can learn the feel of their dives just by following of the track.

Breathalyzer-Key (TAKEN ALREADY by SAAB)
Background:
No more drunk driving
Invention:
So basically, you have a key that's retracted in a little tube and cannot be used until you blow into the breathlyzer that's attached. So if you're drunk, your key will not be accessible.

Please criticize, comment and provide other creative ideas.
