## Picture this:

You're waking up in your beautiful new apartment, looking out on the canal it's situated upon. You sit at your kitchen counter with a cup of coffee, grab the stack of envelopes waiting to be opened, and peruse the invoices within to be paid. But one is missing.

It's the electricity bill.

You frantically search through your mail — and then you remember. You don't have an electricity bill. Because your new apartment is part of a giant circular "Windwheel" that not only generates enough power for your complex, but enough to power your whole town.

Waking up in this building would be such a trip! Image from Dutch Windwheel.

## Does a giant Windwheel you can live in sound like a fantasy? Well, it's actually closer than you think.

It's a plan that's so zany it just might work, and its itty-bitty prototype is expected to be easily scalable to the sizes required for the head trip we just went on to become a reality. And it could be ready to operate and live in within 10 years.

## How does this Windwheel thing work?

Here's a glimpse of the concept from the Dutch Windwheel company and the Delft University of Technology. Mary Beth Griggs explains in Popular Science:

"Horizontal beams will stretch across the center of the Windwheel. Thousands of nozzles located along them will spray positively charged water molecules into the air. When wind pushes the droplets against the beams' high-voltage electric field, it will create a negative charge.

The negative charge will form a current as the electricity discharges, much like when the negative charge that builds up in thunderclouds discharges to the ground via lightning strike. The electricity will then be converted from direct current (DC) to alternating current (AC) for use in the Windwheel or storage in an industrial battery."

Or here's another way of looking at that.

We know we can harness energy through mechanical conversion via windmills and wind turbines, like so:

But these Delft University of Technology geniuses wondered if they could get the energy without the mechanical part. (Short story they can.)

"We wondered whether it is possible to produce energy from wind without the conversion via mechanical energy. It is! By letting the wind move charged particles against the direction of an electric field. How does that work? This is an electric field and a positively charged particle. This can be any object that can hold charge. For example, a ping pong ball. But for the EWICON, we use water droplets. The electric force of the field moves the particle toward the negative electrode. Now when we let the wind push the particle toward the positive electrode, the potential energy of the particle is increased — similar to pushing a rock up a mountain against gravity."

They're already using this technology on a much smaller scale and looking to improve its efficiency. Researchers think that with funding and more work on the design, it can be ready to go, in an affordable way, in a decade. And they're betting that making it a design that actually provides housing — yes, actually being able to live in one of the magical Windwheels — is a win-win economically.

It's also proposed, as shown in this diagram, that the Windwheel could have solar panels to enhance its energy production capacity.

It's not clear if this technology could eventually be retrofitted to benefit existing apartment buildings, and we're a bit too far from the actuality to start putting in a rental application for the first Windwheel apartment just yet, but...

And for people who are looking forward to seeing their electric bills go down (not to mention switching to cleaner energy), it won't be a moment too soon.

## Global mayors are declaring their commitment to divest from fossil fuels and invest in a sustainable future

True

\$200 billion of COVID-19 recovery funding is being used to bail out fossil fuel companies. These mayors are combatting this and instead investing in green jobs and a just recovery.

## Hero pilot 'Sully' asks Americans to deliver a clear cut message to Trump on Election Day

Chesley "Sully" Sullenberger made an international name for himself in 2009 when he safely landed US Airways Flight 1549 in the Hudson River, saving all 155 people aboard. The former Air Force pilot and airline captain earned the nickname "Hero of the Hudson" for his cool head and expert execution of the near-impossible feat, and a feature film with Tom Hanks playing him told the story of that fateful flight.

In 2009, the GOP approached Sully, a registered Republican, about running for office in his home state of California, but he said he had no interest in public office. In 2018, he wrote in a Washington Post op-ed that although he'd been a Republican for most of his adult life, he had "always voted as American."

Now, Sully is putting country above party again in an ad created with The Lincoln Project and VoteVets. In it, Sully details what leadership entails. "Leadership is not just about sitting in the pilot's seat. It's about knowing what you're doing, and taking responsibility for it. Being prepared, ready, and able to handle anything that might come your way."

## School responds to a parent's book complaint by reading it aloud to the entire student body

Schools often have to walk a fine line when it comes to parental complaints. Diverse backgrounds, beliefs, and preferences for what kids see and hear will always mean that schools can't please everyone all the time, so educators have to discern what's best for the whole, broad spectrum of kids in their care.

Sometimes, what's best is hard to discern. Sometimes it's absolutely not.

Such was the case this week when a parent at a St. Louis elementary school complained in a Facebook group about a book that was read to her 7-year-old. The parent wrote:

"Anyone else check out the read a loud book on Canvas for 2nd grade today? Ron's Big Mission was the book that was read out loud to my 7 year old. I caught this after she watched it bc I was working with my 3rd grader. I have called my daughters school. Parents, we have to preview what we are letting the kids see on there."

## Amy Klobuchar's masterful response to Ted Cruz's SCOTUS nomination argument is a must see

The recent passing of Ruth Bader Ginsburg not only marked the end of an illustrious life of service to law and country, but the beginning of an unprecedented judicial nomination process. While Ginsburg's spot on the Supreme Court sits open, politicians and regular Americans alike argue over whether or not it should be filled immediately, basing their arguments on past practices and partisan points.

When a Supreme Court vacancy came up in February of 2016, nine months before the election, Senate Republicans led by Mitch McConnell refused to even take up a hearing to consider President Obama's pick for the seat, arguing that it was an election year and the people should have a say in who that seat goes to.

Four years later, a mere six weeks before the election, that reasoning has gone out the window as Senate Republicans race to get a nominee pushed through the approval process prior to election day. Now, they claim, because the Senate majority and President are of the same party, it makes sense to proceed with the nomination.
