I did a science fair project on this one... A tooth brush that had tooth paste in the handle which would dispense through a tube into the bristles. Of course to market such a thing it would either need to be disposable or refillable. I had a proto-type at the fair and everyone liked it. What do you guys think?Reward: Just the satisfaction that I had a good idea.
If you have really energetic dogs at home, but you never have time to play with them, or you're too tired, this is perfect for you. It is a machine that plays fetch with your dog(s). Place it in a corner of your yard, put a time you want it to play, then let it loose. It has 10 tennis balls in a compartment inside it. Inside those balls are powerful magnets that get attracted to the machine when the machine runs out of balls. Like the machines you see in tennis courts, it will throw the balls in many directions at intervals of 20 seconds, plenty of time for your dog to chase them. Then it will neatly pick the balls up, leaving your yard balls-free.Reward: get it for free, the ability to use it in a science fair without getting sued.
I propose that the national government expend public funds to sponsor scientific research by creating a comprehensive Academic Papers Database. Many journals and data warehouses exist to contain academic papers, but a central data repository would have numerous advantages.1) Undergraduate students who produce papers for college could have their papers permanantly inducted into the database when submitted for grading in electronic form. Thereafter, University Professors all over the country could execute a text comparison search against papaers already in the database to detect plagarism.2) Graduate researchers and specialists could search a single Internet source for their research rather than many.3) The data warehouse would serve as a repository of human knowledge that could be easily archived in permanant (optical) form as a time capsule of the 21st century.4) We could better share work with other nations and between scientists with a central resource.5) The government may need to restrict access to certain types of information in order to protect from terrorist attacks. A central warehouse for information can be made secure, but uncontrolled stockpiles of information on nuclear physics, bio-terrorism, explosive chemistry, et cetera could be exploited by the wrong people.6) Centralized data containment can become a source of public revenue by charging for access time to the database. Naturally, the price would be kept low due to the efficiency of centralized management. Rather than belong to 10 scholarly journals that impose high fees, a researcher can use the comprehensive Academic Papers Archive for one low price.7) Library science can grow to its fullest potential only when all of the information in human civilization is availible for review by a single administrative organization. The science of classification to facilitate searches requires the broadest possible flexibility to permit interdisciplinary sciences to emerge and grow.8) Outdated information that is no longer current or valid can be rejected when all the data for a given subject is under central review. Modern research proceeds as fast as individuals can get information about the subject and how it changes ; if the turn around time for experimental ideas improves, science will discover new knoweldge faster. 9) The paper volume of scientific information doubles every decade. To slow this explosion of scholarly effort, we must ensure that people can know what is currently open for investigation all over the world in all fields. That way duplicated effort will be done to verify or disprove results, but never "overdone" by more researchers than are necessary to complete a given task.10) Textbooks about the subjects of knoweldge can be written once the database gets formed ; a comprehensive database could lead to text books that are the most comprehensive, balanced, and fair treatments of the subjects that can be made.Reward: I'ld like to be able to surf the Academic Papers Archive to read the latest research in all fields of interest!
Suppose you take a beer or soda out of the fridge, it feels cold but you're not sure. But you noticed something really neat on the side of the can: The distributer, may it be pepsi or Budweiser has installed, right onto the side of the can a simple yet effective thermometer. And it tells you your beverage is cold, and ready to drink.Reward: whatever is fair
This idea sort of falls under environment, but I bet more people would look at it here, so here she goes.Busses travel in most cities for at least 15 hours of the day. During that time the bus may cover up to 300km. A filter placed on the roof of the bus would see a fair amount of air in one of those days. For example, if the dimensions of the filter were 2.5 x .5 meters then in the course of the day one bus could filter approximately 250,000 cubic meters of air. Filters could be washed and pellets made of the dirt collected. These pellets could be disposed of properly. This would make the cities a cleaner place. The governments could subsidies the bus companies and every one would be happy.Reward: Recognition
