Here’s a piece from Fossbytes, the same people who claim that the costs of maintaining EVs is greater than that of gas- and diesel-powered vehicles.
A cargo ship named the Pyxis Ocean equipped with two 123-feet-tall WindWing sails embarked on a journey from China to Brazil last August, aiming to test the efficacy of the wind-powered technology.
After six months of sailing worldwide, Cargill, the ship’s owner, unveiled the results. On average, the Pyxis Ocean saved 3.3 tons of fuel daily.
It showed potential savings exceeding 12 tons per day in favorable weather conditions, resulting in a 14% reduction in greenhouse gas emissions.
WindWing’s makers suggest even greater fuel savings with three sails. Although promising, the challenge remains in adapting ports to accommodate such vessels. Cargill is actively engaging with ports globally to address this concern.
A couple of points:
As the wind industry has known for more than a century, the amount of power derived from capturing some of the kinetic energy from moving air is proportional to the area of the blades or sails on which the wind is incident.  From the picture above, does it seem possible that huge, ocean-going cargo ships can be powered effectively from these two tiny sails?
It’s interesting that this is an artist’s rendering, rather than a photograph.  It is significant that such devices do fact, in fact, exist?
There is no doubt that this will save on fuel.  The ships the Vikings piloted around the open seas required no fuel either.  If we don’t care how long it takes to ship our goods across the Pacific, perhaps this is a good idea.  But of course, we care a great deal about modern supply change logistics.

Bravery Meets Tragedy: An Unending Story

Published

Here’s a story:

He had 3 days left until graduation.

STEM School Highlands Ranch. May 7, 2019.

Kendrick Castillo was 18. A robotics student. College bound. Accepted into an engineering program. The final week of school felt like countdown, not crisis.

Then a weapon appeared inside a classroom.

Students froze.

Kendrick did not.

Witnesses say he moved instantly. He lunged toward the attacker. No hesitation. No calculation.

Two other students followed his lead.

Gunfire erupted.

Kendrick was fatally sh*t.

But his movement changed the room.

Classmates were able to tackle and restrain the attacker until authorities arrived. Investigators later stated that the confrontation disrupted the attack and likely prevented additional casualties.

In seconds, an 18-year-old made a decision most adults pray they never face.

Afterward, the silence was heavier than the noise.

At graduation, his name was called.

His diploma was awarded posthumously. The arena stood in collective applause. An empty seat. A cap and gown without the student inside it.

His robotics teammates remembered him as curious. Competitive. Kind. Someone who solved problems instead of avoiding them.

He had planned to build machines.

Instead, he built a moment.

A moment that classmates say gave them time.

Time to escape.

Two points:

If you can read this without tears welling up in your eyes, you’re a far more stoic person than I.

Since Big Money has made it impossible for the United States to implement the same common-sense gun laws that exist in the rest of the planet, this story will reduplicate itself into perpetuity.

How often does this happen? How about never?

Trump loves to say that little boys go to school and come back home little girls.

He’s the most powerful person in the world for exactly one reason: We’re a nation of morons.

Two comments:

That the United States has homeless veterans is a national (and international) disgrace.

By definition, no one has the legal right to enter the U.S. illegally, but according to our constitution, everyone in America is entitled to due process.
