Yes, the control needs to be continuously variable, but I think that a stack of D-Drives would reduce the torque required by the control system for power control of the final drivetrain, by their reduction, to the point where a relatively small electric motor could do the job.
I agree, it sure looks like the output torque is generated by pushing against the control drive motor, meaning that maximum torque at ratios less than 1:1 is related to the rating of the control drive system.
The control system has the smaller central gear, so there will be some mechanical advantage that will "step up" the torque the control system can provide, allowing for a smaller control powerplant.
He mentions a kinetic recovery system to power it, which to me indicates an intention for intermittent use. I'm thinking its target purpose is as a no-wear mechanical clutch. Without power input, it sends full power through, which is bad for a failure mode... but good as a clutch. I interpret that the control is least power hungry at ratios close to 1:1 and demands the most power at low ratios; however, I think the "powered zero" requires little power, since there is no torque output.
You could attach smaller version of this device to a PTO to drive the control system variably from the drive motors own power, and control it with an even less powerful electric motor. Stacking the control system(s) like this could allow large scale versions.
An expert in fluid mechanics from Purdue, Steve Wereley: "I spent a couple of hours this afternoon analyzing the video, and the number I get is 70,000 barrels a day coming out of that pipe," said a Purdue University mechanical engineering professor, who used video footage and a particle velocity analysis to come up with that 70,000 barrel per day amount.
That is around 3,000,000 gallons per day. Still less than the quoted original article, but closer to a linear, not exponential difference.
I stand by my previous comment.
Given the time wasting charade / shell game BP is playing with solutions: A Box, A hat, Now a sippy straw.
And the variability and increasing magnitude of the different numbers they provided. Let alone news surface photos that seem to be polarized not to show oil sheen. Or any admission of the massive undersea spread of oil and gas. (oil blobs are found in subsurface samples far from the surface slick). (In fact their continuous sub-sea dispersant release is designed to do exactly that)
I would tend to believe misinformed internet nutjob numbers (with some linear adjustment) vs corporate PR swindled digits.
Thanks for pointing that out, that makes it much more interesting an achievement.

That site is kind of like living with strange and often helpful people who leave you cryptic notes on your fridge, with pictures of your mom from some party you swear you don't remember being at. And yet all that is somehow comforting. A sort of magic 8 ball that both answers and re-enforces some of the lunacy and hivemindedness I remember from lambda moo. Also be sure to go there and ask people about the secret board where you can play "the game."
I recollect that computation, imaging hardware and certain algorithms were considered "munitions". They were banned from export due to their possible use in weapons and as intelligence devices.
This kind of thing is no different. I now see it as a deep incorporation into our civilian domains of military grade technologies. Information age demands an information equivalent of "posse comitatus" and organizations/corporations such as this could be viewed as illegal private militias.

Boo apple.
The early home computers, including Apple, shipped with BASIC and a nicely bound manual with clear instructions on simple programming. This was the first step for many who are now players in the industry.
As I recall, the story went: Mandelbrot was a mathematician at IBM lab. The engineers were attempting high speed data networking, but were encountering data/signal loss due to some noise. So like good engineers, they made things more robust, better isolation, grounds, shielding, etc. but the darn noise was still there.. They could not get rid of it. Determined to find the cause, they went to Mandelbrot with the request to analyze the noise, to determine its cause, in order to eliminate it.
Mandelbrot examined the data and found that there were periods of clear signal interrupted by noise. He examined the noise and found that within it were periods of clear signal, interrupted by noise and so on. Hmmm... He astutely determined that "shit happens" and what was needed was a redundant protocol, not better shielding. The noise you see, was inherent in a damped and driven system.
It was from this that he began his explorations of fractals and chaos theory, and we got robust network protocols.
Hearings on what?
"There was only one catch and that was Catch-22, which specified that a concern for one's own safety in the face of dangers that were real and immediate was the process of a rational mind. Orr was crazy and could be grounded. All he had to do was ask; and as soon as he did, he would no longer be crazy and would have to fly more missions. Orr would be crazy to fly more missions and sane if he didn't, but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to. Yossarian was moved very deeply by the absolute simplicity of this clause of Catch-22 and let out a respectful whistle."
"That's some catch, that catch-22," he observed.
"It's the best there is," Doc Daneeka agreed.
I've been running "Parallels" VMs over OSX and have to say it has 'whelmed me enough to enthuse about it.
It can VM OSX'n linux'n and Win 98 thru 7 concurrently from images which can be snapshot, written back, or left pristine after use (disposable OS) or by boot-time OS selection. The copy/paste and crossplatform filesystem accessibility is handy. I've given it some heavy lifting and it works for me, even with only total 1GB RAM before I upgraded.
For the expansion issue, I use a serviceman's combo USB to IDE & SATA device, and leave the drives open, also one or 2 in enclosures.
I heard that in former Yugoslavia during the NATO air raids there, they would spread microwave ovens on long extension cords all over. Then it would look like a bajillion radar tracking sites all over, and these garage sale microwave ovens would get blown up with million dollar radar homing missiles..
Amps were definitely off, I was on the tech crew.
They were drawing arcs from the coil with a ball on a pole.. now I'm certain they were sharing power & ground from our power distro that was tied into the forearm size mains conductors in the breaker room. I thought spark gaps made wideband noise.?.
Ran up a tesla coil at a rave... even tho the amps were powered down, the very large speaker stacks made crazy big pops from the discharge arcs.
I think a HERF on one of those acoustic weapons would blow the speakers and everyone's eardrums.

I threw up in my mouth a little. No one will breed with them. Not even in the back seat of that vw bug.

This could work, so long as they surround the car parks with a high kangaroo fence...

The wall does not have a load on it, otherwise I think it would fully collapse afterwards. Requires structural framing to work.
kind of an inside out airbag.
Wonder how a vehicle with this as a tensile skin would crash test? The body would become a safety cocoon.

TFA points out that the flash code can be pre-pended to the entire .zip family, and more.
It is executable code that doesn't look like it is code. That in a nutshell is the problem, aside from the pt of origin of that code being obfuscated.
Another reason to browse inside a VM. btw, anyone know if any browsers can internally handle parallel authentications (ie a virtual browser)?
This is a read only system for twenty clients Sounds like a routine networking task with standard file sharing.
bulletproof, free and simple and centralized
build the webpages and address the files from the network shares.
people see HTML and automatically assume they have to get it and all the content from a webserver.
that is just creating headaches and extra process. as is the parents suggestion. if your LAN poops on video, buy modern gear.
buy a good network switch to isolate the terminal feeds if you really have a bandwidth concern.
