Turning Gas Guzzlers Into Clean Cars

In Mexico City, more than 3.5 million cars navigate the streets, plazas and avenues of North America’s most populous urban area. That makes for a ton of exhaust, but luckily, there’s a solution to this environmental problem. Enter engineer/auto mechanic Alvaro de la Paz and computer scientist Hector Ruiz. Together, they’re transforming old gasoline-fueled automobiles into electric cars. Over the past decade, the pair has converted more than two dozen vehicles into zero-emissions automobiles. While that may seem like a small dent in an enormous cloud of exhaust, the pair hopes that their project will inspire younger generations to work for a brighter, cleaner future.
