my cynical mind says there's a not insignificant chance that when the trail is fully traced..... it will be Disney themselves selling the data because money is awesome.... right guys? you don't mind criminals stealing everything you have so long as we get more money, right?

That would be incredibly stupid. So it's probably true.

Cracked blades are the #1 maintenance issue, as I understand it.
As I remember from a PBS (or probably Discovery) show, it's the leading edges that really take a beating. They were able to extend the lives a little by reinforcing those edges. (I think this was a show talking about maintenance on one of the farms in the North Sea.)

In a new paper, the scientists integrated tools from social psychology to classify driving behavior with respect to how selfish or selfless a particular driver is.
...
While not yet robust enough to be implemented on real roads, the system could have some intriguing use cases, and not just for the cars that drive themselves. Say you’re a human driving along and a car suddenly enters your blind spot — the system could give you a warning in the rear-view mirror that the car has an aggressive driver, allowing you to adjust accordingly. It could also allow self-driving cars to actually learn to exhibit more human-like behavior that will be easier for human drivers to understand.Robotic Road Rage!

This technology, which uses mirrors to reflect the sun to a single point, is not new.
No, it's not. I remember reading 40–50 years ago about a facility in, I think, France that used mirrors on the side of a large building to focus sunlight onto a single target. I think it achieved temperatures sufficient to melt steel. If not, it was pretty close; it got white-hot, at least.
The problem is that in the past concentrated solar couldn't get temperatures hot enough to make cement and steel.
The solution to that problem is simple — add more mirrors. If the thing you're trying to heat isn't hot enough, focus more sunlight on it.
Heliogen uses computer vision software, automatic edge detection and other sophisticated technology to train a field of mirrors to reflect solar beams to one single spot.
That doesn't need computer vision, edge detection, and other sophisticated technology. Heck, it barely even needs math. The sun follows a very predictable path across the sky. You know the geometry of the mirror with respect to the target, and this is fixed; it never changes (unless you're putting the mirrors on mobile mounts, but why would you do that?). Mount the mirrors to rotate on axes parallel to the Earth's axis of rotation. (This is not a new concept. It's called an equatorial mount, and it's how all astronomical telescopes — except the cheapest of toys — are mounted.) Align each mirror to reflect sunlight onto the target, then rotate each mirror on its mount at 1/2 the Earth's rate of rotation relative to the sun.
Ok, it's not quite that simple. The sun doesn't follow exactly the same path across the sky every day; it varies seasonally in both declination (mostly) and right ascension (a little) as the Earth orbits the sun, and the mirror angles need to be adjusted accordingly. (If you were to record the sun's position at the same time every day for a year, it would appear to move in a tall, skinny figure-8.) But this doesn't need a lot of high-tech buzzwords, or even sophisticated math; it's simple geometry. However much the sun's apparent position in the sky changes, change the angle of the mirrors by 1/2 of that.

@HardwareGeek Thank you for your informative as always
-ry!
Having said that and skimmed TFA, I don't think it actually hypes up the mirror part that much. And a quick trip to Wikipedia tells that temperatures up to 3500 degress have long since been achieved in solar furnaces. But there's one thing - adding more mirrors increases the cost and the surface area required, the latter bringing its own set of problems. As journalism is wont to do, it doesn't mention any useful figures. If the same energy output is achieved with considerably less, by all means let's have it. Instead it makes a big hairy deal about "algorithms" and AI. Basically a bunch of nutters put some passably close figures into a black box and it turned out that the right numbers came out. Who wants to bet that part of the project cost the most? Yeah.

@Applied-Mediocrity said in In other news today...:

That's not really possible either.
- For power, you simply can get about 1 kW from a square metre and that's it.
- Temperature depends on the solid angle from which the Sun rays hit the target, so you can get higher temperature by adding some secondary mirrors, but that should be quite obvious to anybody who understand thermodynamics, so I doubt that's new.
- They could have a better material to hold the target now, but that does not seem to be what TFA talks about, right?
-
@Bulb How far from the theoretical maximum are we currently? Is it very close? I mean, I don't know. If I did, it would probably be
.
-
@Applied-Mediocrity Isn't the theoretical maximum the actual temperature of the light-emitting surface of the sun?
-
-
@PleegWat That, and not all of the energy spectrum passes through various layers of the atmosphere, yes.
But what I was thinking of was - how much of that up to 1kW/m2 that does reach the reflector in some way can be gathered with current technology, given the numerous ways the atmosphere can scatter the rays and change wavelength, and can there be some technomagical process that adjusts to it while not introducing high energy losses (from moving mirrors) itself.
Does that make sense or I'm low-rate technobabbling perhaps due to being rather ill at the moment?

A lawyer for the government acknowledged that it wouldn't be theft to remove a tracking device put there by a private party. But he argued that things are different when the government has a warrant to use a tracking device. The device had a legal basis for being on the car, the lawyer argued. By removing it and preventing tracking, Heuring was depriving the government of the use of its property.

I believe 1kW/m2 is (approximately) the power density (power/area) that actually reaches the surface, after taking the atmospheric scattering, etc., into account (under ideal conditions; it's considerably less when the sun is low in the sky — early morning, late afternoon, high latitudes — or, of course, cloudy skies). How efficiently that can be captured and utilized depends on what you want to do with it. If you just want to heat something up, like melting steel or calcining lime to make cement, it depends on the reflectivity of the target; a flat black target is going to absorb the energy much more efficiently than, say, polished aluminum. (Also, how well you can insulate it to prevent the absorbed heat from being lost to the surroundings.)
If you want to use the heat to do work, say, make steam to run a turbine, then you have to multiply the efficiency of the absorbtion by the efficiency of the process you're using the heat for.
can there be some technomagical process that adjusts to it while not introducing high energy losses (from moving mirrors) itself.
Thermodynamics is a harsh mistress. The amount of power input to the system is strictly limited by the number of square meters of mirror you have. The efficiency is limited as described above. The moving mirrors focus the moving sunlight onto a stationary target, where it can be utilized (moving the target to stay at the focus of stationary mirrors would be more complicated and almost certainty less efficient), but there's no way to compensate for losses except to increase the area of mirrors. And moving the mirrors isn't introducing a high energy loss. The motors to move the mirrors are low speed and low torque; you could probably run the motors for a hectare of mirrors from a few square meters of photovoltaic cells.
