So I guess this is not Blest (which I heard first time.)

In case anyone else is following along, a patent by Pringle has had a very intriguing set of assignments.

Started out with the corporation by Pringle and Co in 2009, rest is below:

2009: GREENTECH ENERGY SOLUTIONS LTD.

2010: UNIVERSAL ALTERNATIVE FUELS, INC.

2011: GORTAGCH DEVELOPMENT LIMITED

2015: GREENTECH ENERGY SOLUTIONS LTD.

Pringle also has a 2020 patent application pending that references the 2006 original filing.

I would think air (line) drying would be better in terms of microplastics, since there is no tumbling. Would it be safe to say that (mostly) frictionless line drying would shed fewer particles than tumble drying?

The dryer collects already loose or broken fibers in the lint trap for disposal. Air drying doesn’t which means those large broken fibers containing several orders of more magnitude more plastic than might escape from a dryer end up in the environment. This is why new clothes result in dramatically more lint than old clothes by weight.

Isn't it possible that tumbling is the only significant source of breakage?

Oh, I noticed the domain name being blest.co.jp.

> INCORPORATED March , 2018

So someone bought it and keeps it running? Interesting.

I remember nearly two decades ago a PopSci article about some guy who figured out how to use microwaves to convert plastic (any hydrocarbon) into oil and natural gas. More than enough to break even. He was converting tires and waste plastic. Nothing ever came of it - IIRC, ownership disputes with the partner, and eventually the patent got purchased by some random company and blackholed. Edit: found a source. Better t…

> It doesn't sound expensive to add water injection to an internal combustion engine, until you have to make it work in production, with end users.

Water / methanol injection was commonly used on various piston engine aircraft in the 1940's. It had several benefits, cooling the input air, preventing pre-detonation at high compression (due to lower octane fuel in some cases), lowering the combustion temperature, and such. It was practical and worked fine for high-performance aircraft, that saw regular maintenance after every flight.

It doesn't seem very necessary or practical for a ground vehicle though.

Great, another reason I'm pissed off about plastic recycling! I've been collecting my plastic for as long as I can remember and recycling it, then they tell us only about 12% has EVER been recycled. Now we can break it down to get the oil back! A$$holes!

Be careful where you get stats like that. If the stat says that "12% of plastic (ever produced globally) is recycled" that doesn't mean your local recycling program is terrible.

I just got a notice from my trash company that only 10% of their collected material is contaminated / not recyclable.

If that was the case old clothes would produces far more lint in a dryer because the dryer would keep damaging them. Instead the reverse happens with new clothes produces vastly more and it tappers off.

They do cause damage, but it isn’t the overwhelming source of damage.

"This sounds too cool, let's check HN comments for the disappointment"

If you wanted to burn plastic for energy, you can already do it at a electrical generation plant. You have to put more energy in to get oil out. Um. And climate change.

Burning plastic however, has high temperature requirements to avoid giving off toxic fumes in the smoke, which I think you would reduce by doing a conversion to oil first.
