Invention of the Day: A Bladeless Windmill

This story first appeared on the Atlantic Cities website and is reproduced here as part of the Climate Desk collaboration.

It may look like a giant airplane window strung with Venetian blinds, but this structure, designed by Dutch architecture firm Mecanoo and installed at the Delft University of Technology this month, is a model of a machine that would convert wind to energy without any moving parts.

Any mechanical moving parts, at least: the technology, developed by the Electrical Engineering, Mathematics and Computer Science faculty at Delft, uses the movement of electrically charged water droplets to generate power. How does this work? A handy video explains:

 

 

The prototype of the EWICON (Electrostatic Wind Energy Converter), as envisioned by Mecanoo, has the potential to change the use of wind technology. The EWICON absorbs little wear and tear, requires hardly any maintenance, but most importantly, it makes no noise and casts no moving shadows, two of the principal complaints that hinder windmill installation in the United States.

This, Mecanoo believes, makes it the ideal feature for urban environments — they’ve already incorporated them into their design for a project in Rotterdam.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

Headshot of Editor in Chief of Mother Jones, Clara Jeffery

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
