Retrofitting Two-Stroke Engines Good For Everyone

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


An independent nonprofit out of Colorado has developed and disseminated a retrofit kit designed to reduce emissions from the ubiquitous two-stroke motorcycle taxis in the Philippines. A single motorcycle taxi with a traditional two-stroke engine emits as much pollution as 50 modern automobiles, and the Asian Development Bank estimates 100 million two-stroke vehicles ply the roads in Southeast Asia &mdash that’s right, the equivalent of 5 billion cars. The Worldwatch Institute reports that Envirofit has won a World Clean Energy Award for developing and disseminating a retrofit kit, originally designed for snowmobiles. In the retrofit, the carburetor is eliminated and fuel is introduced directly into the engine cylinder, so less unburned fuel is wasted. The typical Filipino taxi driver makes only $3–5 per day, and the kits pay for themselves in fuel savings within 10 months. Envirofit hopes to expand its engine retrofit program to Bangladesh, Sri Lanka, Pakistan, and India, where demonstrations of the product will take place this year.

Now, can we just do away with jetskis, the most hateful of all the 2-stroke blights? According to the EPA, older jetskis (still prevalent around the world) cause more nonpoint source pollution (translation: runoff) in two hours than a car running for an entire year. Truly fun for the feeble-minded. JULIA WHITTY

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
