Revolutionary headphones Printer Friendly Version
One of the biggest drawbacks of headphones is that they block oxygen supply to the ears. Hence when you use them more than a few hours a day you start getting ear related problems. So my idea is a head phone that won't give you any problems, even if you use them for 8 hours+ or more ( you know people in the service industry call centers etc , basically those people who are not audiophiles.)
These head phone will have two modes, simple (no amplification) and powered mode (sound amplified by an external source). Now the most important part . These will be absolutely non contact head phones i.e they will not touch any part of your ears. The mounting will have to be designed in such a way that both the speakers hang tightly near the ears without touching them. The head band will lock on the head over the ears and by using a special adjustment meter, the user can define the distance of each speaker from his ear lobe. Once the adjustment is done, the next time the user just wears the headphone and they fit exactly at the place where he wants without touching the ears. Have you tried this? Just take two speakers very close to your ears, don't touch them and listen to the rich surround experience that you get and your ears do not hurt. This is what the new head phone design will offer.

Open Source Auto Industry Printer Friendly Version
The auto industry today has some major flaws. You buy a new car for a large sum of money, after 10 or 12 years, the repair costs are more than the value of the car, so you toss it into a junkyard and buy a brand new car. The car companies are rewarded for making a car that is difficult to repair. In some cases, it seems like they are intentionally designed so that customers cannot work on them themselves. The cars must be taken to the dealer and the repair costs are outrageous.
Here's the solution: in the aeronautics industry, aircraft are designed for ease of maintenance. Many aircraft are designed to last 100 years and to have parts that are easily replaceable. The concept of designing products for a maximum life and ease of maintenance and repair is known as sustainment.
In the arms industry, many firearms are designed to maximize the compatibility of their parts. Parts for a Colt 1911 made in 2015 will be compatible with parts made in the 1930s. An AR-15 upper receiver made by Smith & Wesson is compatible with a lower receiver made by Bushmaster. Compatibility.
Last, in the world of open source software, the intellectual property is built by volunteers all around the world who wish to create a better product for themselves and everyone else. Also, projects like the Adruino have created open source hardware and have dramatically driven down the costs of custom circuit boards by opening their designs to the free market. This is the beauty of open source information.
What I want to do is to create a car company that uses the best of all of these worlds. Cars that are designed to last a lifetime because they are designed for ease of maintenance. Parts that will fit your car today, and in 50 years you will still be able to buy parts that fit. Last, all intellectual property will be open source. This means people from all over the world will be able to propose design improvements and create new 3D models using open source software. Also, this will open the door to the free market so manufacturers from all over the world will be able to manufacture parts that fit together. You can buy an engine from Honda and a transmission from Toyota and they will be compatible in the same car. Designing cars for sustainment and compatibility with open source information will revolutionize the auto industry. It will make cheap and reliable transportation available to everyone on the planet.
Reward: To change the world
