1.A Font That Could Save Millions of Dollars — Suvir Mirchandani
Science Fair Projects
Suvir Mirchandani a middle school student from Pittsburgh, Pennsylvania was looking for a way to save his school money after he discovered that the printer ink was much more costlier than French perfume. He did a comparison-check of ink used by 4 unalike fonts — Garamond, Times New Roman, Century Gothic and Comic Sans, and later took a print-out of a magnified version of the main vowels and weighed each printout to compare how much ink was used on each sheet. He discovered that if his school moved to Garamond the likely saving could be over twenty thousand dollars a year in ink alone.

He applied the same principle to the U.S. federal government, and discovered that by merely changing the font used in their printouts could cut their costs by over a hundred million dollars a year.

2.Nuclear Fusion Reactor — Thiago David Olsen

15-year-old Thiago Olsen spent a year researching and another to build his own nuclear fusion reactor in his garage. While the device makes energy by fusing atoms — it has been adjudged safe by radiation officials. However, it just generates enough energy to warm a cup of coffee.

3.Mind Controlled Prosthetic Limb Project — Anand Srinivasan
3
15-year-old Anand Srinivasan entered the 2012 White House Science Fair — and was able to design a well functioning g prosthetic arm that can be controlled by thought alone.

The robotic arm responds to electrical signals from the brain, ascertaining which signals to use by mapping them all with an EEG machine.

4.Chemical-Sniffing LEGO Robot — Anna Simpson

Anna Simpson a high school student designed a chemical detecting robot for Intel’s International Science and Engineering Fair in 2009. She designed a mobile robot employing LEGO bricks and fairly basic electrical parts. It can perceive and react to chemical spills by way of a porous silicone chip that turns a different color when it meets a volatile organic compound. Her invention would help to fight terrorism.

5.Plastic-Eating Microbe — Daniel Burd

Daniel Bird designed a plastic eating microbe — that he entered into the Canada Wide Science Fair in Ottawa, Ontario. He invented a way to accelerate the microbial decomposition of the plastic employing a compound that has yeast (among other things), and isolates the most productive microorganisms.

Using the product he was able to bring on 43% degradation of plastic in just six weeks – a big improvement over the natural plastic decomposition rate.

6.Space Exploration Balloon — IES La Bisbal School
6
Now it would not cost over a billion dollars to reach space — some students from the IES La Bisbal School in Catalonia, Spain have designed a latex ballon to make it fairly cheaper. The students and their teacher built a protective rig, housing an electronic sensor and a Nikon Coolpix camera, which they connected to the latex balloon and allowed it to fly. The balloon rig soared over 100,000 miles into the atmosphere, and reached the edge of outer space.

7.Image-Based Search Engine — David Liu

David Liu has created an image based search engine that would make our online lives easier. David invented a way to program AI to search through heaps of images and list these images automatically. The process is dubbed Semantic Image Retrieval and Interactive Exploration of Large Image Collections. For his invention he bagged the second place at the Intel Science Talent Search competition in 2010.

8.Nuclear Weapon Detector — Taylor Wilson

Teenager Taylor Wilson designed a user-friendly weapon detector in his garage that would help armed forces easily detect nuclear bombs and similar stuff. His device can scan cargo like an X-ray, showing any materials or fingerprints which have been exposed to radioactive materials. The device is powered by a nuclear fusion reactor – another invention of Taylor that he came up with when he was just fourteen years old. Taylor debuted his device at the Intel International Science Fair in 2011.

9.Teaching Robots To Speak English — Luke Taylor
9
Luke Taylor a high school student from South Africa has designed an impressive system that teaches robots how to understand verbal commands. The sofware lets Luke give the robot commands in English, which the robot’s onboard memory translates into code, thereby enabling it to be commanded by voice. Amazing!

10.Managing The Power Of Household Devices — Ankush Gupta
10
Household electronic devices slurp tons of power, and elevate our overall carbon footprint on a daily basis. The concept called Domotics—employing electronic techniques to manage household devices could put a stop to the wastage. Ankush entered an algorithm for intelligent power management, into the 2011 Google Science Fair. It showed a 20% reduction in overall usage when deployed at local businesses. Interestingly, it can be controlled with a smartphone.

11.Spacecraft Navigation Software — Erika DeBenedictis
11
18-year-old Erika DeBenedictis designed an updated method of calculating the gravitational influence of planets and how they move, which would enable charting of easy transit routes through the solar system. She was awarded the first place prize – and $100,000 grand prize – at the Intel Science Talent Search contest for her interstellar mapping system.
