Underwater Turbines Set To Generate Record Power

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.


Here’s a preview of the future. Twin underwater turbines are set to generate 1.2 megawatts of electricity off the coast of Northern Ireland by year’s end. New Scientist reports how the world’s largest tidal power project will use underwater turbines that look and work like wind power turbines, with blades up to 60 feet wide. Tidal currents will rotate the rotors at 10 to 20 revolutions per minute — a speed that Marine Current Turbines of the UK claims is too slow to affect marine life. The turbines will drive a gearbox that will drive an electric generator. The resulting electricity will be transmitted to the shore via an underwater cable. Eventually, MCT intends to build farms of turbines consisting of 10 to 20 pairs each. . . This is intriguing, probably necessary, and will doubtless lead to some kind of negative environmental issue(s). Let’s hope the Brits monitor the impacts of what sounds like a promising, hopefully sustainable, technology &mdash one desperately needed on our tough road to a new energy economy. 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.
