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.

A Return to Wind-Sailing Cargo Vessels?

Myth Busting in Renewable Energy

I met a guy earlier today who told me that wind and solar are controversial, and that some people say that the mining and manufacturing of wind turbines requires more fossil fuels that the turbines themselves produce.

I told him that I’m aware of such people; they’re called “professional liars.”

I explained the concept of EROI, energy return on investment, and surprised him by saying that the EROI of wind is somewhere between 18 and 30, meaning that each wind turbine you see as you drive along the freeway will generate at least 18 times as much energy as was required in its mining, fabrication, installation, maintenance, and decommissioning–all the way up to 30 times that amount.

The generation of disinformation of renewables has become a cottage industry.  People are paid to make up and publish complete bullshit, so as to discredit the burgeoning clean energy industry, and keep Big Oil in place.

Thanking God for Trump

As bad as things are in the United States, they could always get worse.

Trump could succeed in his quest to be a dictator, Christianity could be taught in schools, and unvaccinated adults and their kids could trigger another epidemic.

In terms of our reputation on the world stage, however, things really can’t get must worse; the countries around the globe already regard us with a mixture of hate and derision.

Yet regardless of what the future holds, there will always be idiots who that believe that Trump is our savior, like the author of the meme above.

Good to see John Eastman disbarred in California; it’s a small measure of justice.

Criminal prosecution in the future?
