Asking as an ill-informed European. Is this the Koch of the Koch Brothers that I only know as the financiers behind the GOP and climate denialism and bankrolling efforts to gut environmental protection laws?

The Koch brothers are complicated. I found the Freakonomics interview with them very interesting: https://freakonomics.com/podcast/why-hate-koch-brothers-part...

The most interesting quote (from part 2 of the interview):

> Charles Koch argues that the biggest threats to America these days are special interests, cronyism, and corporate welfare. Which may seem strange if you think of a corporate CEO, like Koch, as a beneficiary of those things. He also argues that our political system has turned into a dumpster fire, with both parties guilty of rent-seeking and putting their thumbs on whatever scales they can find. Which may also strike you as strange, if you consider that what a political network like the Koch Brothers’ network does is — well, puts its thumb on the scale. Because he primarily funds Republicans, and because so much of that funding is “dark,” anonymous money, he is seen by most Democrats as something close to the devil — even though some of his positions, as you’ll hear today, align quite snugly with traditional liberal positions.

> My overall impression from speaking with him? Charles Koch believes he’s fighting the good fight based on proven principles — and that the rest of America has been going mad, bit by bit.

Seems like they installed variable frequency drives (their "algorithm) on their motors; nothing more.

I was thinking the same thing. They're somehow sayin they're doing something on top of vector drive: http://ackinetics.com/?page_id=5115 . They claim a lot of lot efficiency with their algorithms: http://ackinetics.com/?page_id=5120

I learned something new, the efficiency rating is really different than what occurs when in use, so 90% efficiency pans out as less than 70%. So the work here is to keep the temperature of the motor down to maintain efficiency. the difficulty is not all motors are of course able to be programmed so while this fix will help those that are it does point out that there are still big energy savings to be had to replace e…

You can "program" any motor via an MCU. All motors are "dumb" unless we are talking stepper motors, and even then they are still "dumb", just not even useful unless you have support hardware

The article is a bit misleading. They talk about how many AC induction motors there are and how much power they consume. I don't doubt those numbers. But the vast majority of those are synchronous: they run at a set speed. What they are working on is variable speed motors which need a special "drive" (aka VFD) device to convert the constant 50 or 60 Hz power supply to a variable frequency. Now VFDs are getting more c…

No. AC Kinetics appears to offer significantly improved efficiencies over VFDs: http://ackinetics.com/wp-content/uploads/AC-Kinetics-60Hp-Tr...

This headline is misleading clickbait. Koch Industries owns a company that's developing software that could reduce AC induction motor energy consumption by 1/3. They haven't actually done it yet.

Incorrect. They have done it: http://ackinetics.com/wp-content/uploads/AC-Kinetics-60Hp-Tr...

To be clear, AC motors can already be 98+% efficient. So, those double digit gains are inherently limited to a subset of relatively inefficient motors. It’s very much useful research, but don’t expect miricals.

But how big is that subset? If most motors run at constant power and speed, then that subset is small. But I suspect there are huge numbers that vary their load constantly, and don't come anywhere near 98% efficient.

The Koch brothers hired private investigators to trail, intimidate, and attempt to get dirt on Jane Mayer when she was writing Dark Money -- a book about how they covertly funded ultra-right wingers and climate sceptics to protect their hundreds of billions of dollars of oil investments. Charles Koch literally shoulders a non-trivial amount of responsibility for a possible coming semi-apocalypse, and he makes plenty…

If you upvote me, I'll pay you!

This is also something the Koch's do -- they fund many astroturfing groups, e.g. Citizens for a Sound Economy.
