ISEF

SAN JOSE, Calif.--In a showcase of cutting-edge research and innovation, with more than 1,600 students from 59 countries participating, Intel hosts the world's largest pre-college science competition, the Intel International Science and Engineering Fair, here this week. Projects exploring broad topics such as alternative energy, health care, and robotics are all vying for more than $4 million in prizes.

Students wait

Following sessions in the morning, students were dismissed for lunch, then returned to their respective stations to wait for afternoon interviews with judges.

"Once again the Intel Science and Engineering Fair displays the remarkable creativity and ingenuity of young people from around the world," said Shelly Esque, vice president of Intel's Corporate Affairs Group.

Natural Oil Boom

In an interview with one of the judges during an afternoon session, students discuss their oil spill solution project, Natural Oil Boom.

Made from the abundant tropical grass Imperata cylindrica, hydrophobic and oleophilic cellulose can be an effective natural solution to cleaning up oil spills.

Alternative energy

Cleantech and sustainable power projects are among the most pressing issues globally, and there are plenty of student projects at ISEF focused on new approaches to energy.

Here, a project explores the different types of inocula on the power output of microbial batteries.

Robotics

As robotics become more integrated into our culture, researchers are exploring ways to make robots more human and intelligent.

This project is exploring the concept of seeing and vision, which gives us the ability to have stereo vision and depth perception, asking whether stereo vision can be applied to robots.

Rubix Cube Solver

David Campeau and Spencer Berglund have built an autonomous Rubix Cube solver using a Lego NXT Robotics System that uses a camera to scan the puzzle, a two-phase algorithm, and pruning table to find the solution.

Wind turbines

Some projects at the fair are seeking ways to increase the efficiency of existing resources and improve the output of current infrastructure without having to invest too much money or resources into increased results.

Examining the details of wind energy, this project is taking a closer look at how we might be able to increase the energy transfer from small wind turbines.

Using a microcontroller-based system to monitor incoming power and system variables, energy to battery transfer efficiency is managed to extract the most energy from the system.

Photovoltaics

Researching concepts to determine the impact of various enhancement methods on the power produced by solar panels, these students are searching for ways to increase yields from solar panels.

By applying lenses, reflectors, and colored filters to solar panels, they hypothesized, the amount of light and wavelength of light entering the solar panel can be controlled so that it produces better and more efficient results, resulting in greater control over the management of solar energy, and potentially receiving up to 25 percent more power.

Wing tip sails

Observing the wing tips of birds inspired this research project, which seeks to reduce wind-induced drag through the addition of adaptive tip sails.

When a wing produces lift, the pressure on its topside is lower than the pressure on its underside, shedding swirling vortices off of the wing tips, inducing drag and making the wing work harder at generating lift.

By using wing tips to push the vortices further from the wing, the drag is reduced, resulting in a lower overall energy consumption.

Energy

Strolling down the energy and transportation aisles of the ISEF, the booths are lined with ideas for alternative energy. This project explores the use of sugarcane waste, called bagasse, as an alternative fuel source to coal.

All's quiet

The hall is quiet, and in just a few minutes, more than 1,600 students will return from the mid-morning break for their final interview sessions with the judges.

The grand awards will be announced at a ceremony on Friday. The top winner in the competition will receive the Gordon E. Moore Award--a $75,000 prize funded by the Intel Foundation.
