Raj Pandian, Professor, Engineering Computer Science Department,
Tulane University, Louisiana, has found a way to use pneumatic
cylinders to convert the energy children produce on playgrounds.
His invention was among The New York Times Magazine's Outstanding
Ideas of 2003. The only Indian on the list — an amazing
achievement for someone who began his education at a municipal
school in Tamil Nadu.
Pandian, who developed a prototype when he was with the
University of Michigan, put pneumatic cylinders under the seats
of a seesaw and connected them to a small tank.
