A recent WSJ article points correctly to the fact that rare earth elements can be recycled from old hard disks, MRI scanners and other gear containing magnets made of rare-earth metals. The startup company Cyclic’s pitch is that this is faster than setting up new mining operations, which can take decades, and slashes carbon emissions and water use.  The picture above is from their literature.

“What we are doing is disrupting that supply chain,” said Cyclic chief executive Ahmad Ghahreman.

The company has invented a process to separate rare-earth magnets from other metals, grind them to powder and use chemicals to extract rare-earth oxides—like hot water releasing caffeine from coffee, Ghahreman says. The company has a deal to supply oxides to Belgian chemicals company Solvay, which processes them to make metal for new magnets.

I applaud innovation of course, but the logistics of getting the candidate raw materials to the processing site and building such a site at scale to be meaningful in modern markets is daunting. Noble for sure … but daunting.  And, if we are to learn anything from recycling plastics in everyday use, it just doesn’t work. Very little of discarded material is recycled … and mostly due to economics. It is cheaper to ship our sins to third world countries and to continue to sin.

You can legislate recycling and charge people per item as they do in the Northeast for plastic bottles, but I have yet to see a study showing that it is making a difference. Frankly, people would rather pay the fee than have their lives further complicated with multiple trash paths. In like manner, composting food waste is certainly a good idea if you have a garden, but very few will do it. Most who do will write articles and get covered by the local news media as heroes, but other than that …

Recycling has been proven to do one thing for sure … and that is to dull the guilt sensitivities of those who consume those goods in the first place. People today buy bottled water, and if you ask them, because they believe the bottles are recycled.

One more convenient myth used by marketers to dull our sensibilities.

Did you ever want to know why you can’t fix stupid?

For years I have been puzzled by the pervasive nonsense I see in politics regarding our clear raping of the planet, most egregiously amplified by recent suggestions that we mine the seafloor.  What is wrong with these people?

Well, here is a video that explains it: Dunning-Krueger Effect Explained

We have the perfect storm of Arrogance and Ignorance (AI) that previous blogs have mentioned is what AI really stands for.  Couple that with the fact that social media has replaced the peer review process and anyone can publish their nonsense, idiots get reinforcement confirming almost any conclusion they reach. 

Please watch this video and decide where you stand.  Are you part of the problem or part of the solution?  I fear the most vocal today are largely the problem and the movie Idiocracy is becoming a reality … smart people are having fewer children than dumber ones, so the average IQ is dropping.

There are signs of hope, and it can’t come too soon. Many scientists and engineers are now correcting some of the superficially appealing notions and trying to develop sustainable energy strategies.  We do have professionals who have repeatedly pointed out that the emperor is nude, like Dr. Katherine Johnson with her insightful weekly postings.  And, as the short article reposted at the end of this blog, there may be a turnaround on some issues.

But we are outnumbered by the dominant ignorant publishing that most read or watch, which they then spout as truth. Plus, we all seem far too tolerant of the increasing abuse of our planet.  Have any of you looked at how we ship goods around the planet?  Do you really think these shipments are all about food and shelter that can’t be provided locally?  Haven’t we considered possibly relocating people to be symbiotic with their local environment?  One of many positive consequences of the current trade war is that it may sort some of this out as each country evaluates whether they need to import vs. make or grow it locally. 

No, we build skyscrapers where nothing grows and malls with ski slopes to prove we can.  We produce and then scrap cars when we can no longer find spare parts or don’t like the styling, rather than build them for long-term use. Or perhaps the most ludicrous is burning fuel moving water (H₂O) all around the world in bottles made of polyethylene terephthalate (PET), a plastic derived from crude oil. 

But why stop there?  How outrageous is it that we are told by politicians that we are going to replace the internal combustion engine with renewables by 2030 or 2050?  Sure, all those 18-wheelers you see on the Interstate are going to run on renewables, plus all the airplanes and ships.  If you think that possible, check out these websites to see how many planes and ships (Ships) must be converted … this is Not happening any time soon.

We need to step back from the abyss we face, rethink our strategies, mend our fences, forgive one another, and start thinking clearly about our choices.  Otherwise, we are heading full speed into worldwide chaos as we allow China to deplete our oceans’ fish, let EV and PV manufacturers rape the planet while killing innocent children sent to mine the needed rare earth minerals, and then pat ourselves on the back with such ridiculous ideas as sustainable renewable aviation fuels.

Sustainable aviation fuel plans under fire over crop emissions  

By Jim Giles May 5, 2025

Scaling the use of sustainable aviation fuel (SAF) made from corn and soybeans is the focus of U.S. plans to decarbonize aviation, but researchers at the World Resources Institute are urging a rethink.

• • The U.S. produces around just 1 percent of the quantity of SAF needed to hit a government target of 3 billion gallons of domestic production by 2030, according to the Department of Energy.

• • But when land-use change is considered, corn and soybean-based SAF creates more emissions than fossil jet fuel, the WRI concluded in a report released last week.

• • The crops “are not a viable strategy for decarbonizing aviation,” said Audrey Denvir, a WRI research associate and author on the report.

Industry figures questioned key details of the analysis.   

“Context is everything,” said Adam Klauber, who oversees sustainability and digital supply chains at World Energy, a SAF producer. Klauber argued that the WRI analysis relied on global averages for the impacts of biofuel crops and overlooked the higher performance of crops grown in the U.S.  In a new report, the WRI team argues that when a more holistic approach is used to assess SAF production, two crops that are essential to scaling supply — corn and soy — are found to create more emissions than conventional fossil fuels.

The crops “are not a viable strategy for decarbonizing aviation,” said Audrey Denvir, a WRI research associate and an author of the report.  SAF advocates disputed the report’s conclusions, saying the researchers failed to distinguish between global averages and data on more sustainable biofuel crops grown in the U.S.

About five years ago, Airbus made a bold bet: The plane maker would launch a zero-emissions, hydrogen-powered aircraft within 15 years that, if successful, would mark the biggest revolution in aviation technology since the jet engine, the WSJ’s Benjamin Katz reports.

The plan raised eyebrows because the technical challenges of the way they were going to do this were huge. Engines would need to be reconfigured to run on hydrogen which would need to be stored in liquid form at minus 423 degrees F. The heavier fuel load and equipment would reduce both seat capacity and range. And then there were the safety concerns exemplified by the 1937 Hindenburg disaster.

The company settled on hydrogen-fuel cells to generate energy for electric motors. But fuel cells are extremely heavy, and the plan required a radical redesign of the airframe and propulsion system which would carry only 100 passengers about 1,000 nautical miles. Plus, as the picture here shows, it is a propeller driven design, so it is certainly not going to fly as fast meaning passengers are going to find their flights longer. This is all just wrong.

The company has spent more than $1.7 billion on the project, according to people familiar with the matter, and over the past year they concluded that technical challenges and a slow uptake of hydrogen in the wider economy meant the jet wouldn’t be ready by 2035. Notice they also failed to admit that hydrogen was going to cost them more than conventional aviation fuel. This was greenwashing at its best, and a complete lack of fiduciary responsibility on the part of senior leadership.

But I blame the scientific and engineering community who knew better. The whole idea was just wrong-headed. That is, until you look at their motivation as the article points out:

“Airbus also had a commitment to a major shareholder—the French state. The company had been a major beneficiary of a Covid-era government support package for the aviation and aerospace sector of 15 billion euros, equivalent to roughly $16.6 billion. The deal required Airbus to spend a portion of the money on bringing green aircraft to market by the 2030s.”

That’s all you need to know. $1.7 billion looks like a small fee to get back $16 billion!  Greenwashing at its best … always follow the money!
