Featured in Forbes’ 30 under 30 – twice – Param Jaggi gained a reputation while still in high school, when he invented a world changing device to convert the carbon dioxide emitted by cars into oxygen. As a child, Jaggi pursued projects related to saving the environment and world problems. By the time he was learning to drive in 2008, and still passionate about the environment, Jaggi sought to invent a device that would reduce his carbon footprint, after seeing the amount of fumes released from a car. At just 17 years old, he built his bio-reactor. Filled with algae, and therefore named the Algae Mobile, the device fits over a car’s tailpipe, allowing the algae to convert the toxic gas. His invention won Jaggi an award from the Environmental Protection Agency.
