First we had windmills. Then wind turbines. Now it's time to meet the Windwheel.
Those delightfully zany Dutch have done it again!
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.

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...
2025 is the projected year that the Windwheel could be up and running.

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.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
