How does it solve for time without location? With GPS location and time are one solution to an equation with 4 unknowns (x,y,z,t). Without location you won't know the time delay between you and the transmitter.
Perhaps they were just hand-fed to demonstrate accuracy.
If instead of PPS it gave a 10Mhz reference, then there is a pretty good use in keeping nearby systems sample-synchronized. In which case you don't care about 'time' just about frequency accuracy.
I have bought the new SQ probes and went back to only buying the older version.
The new ones are heavier, but that makes it harder to put them at an angle, they fall over more quickly. And the probe heads are bigger so you can't put as many close together.
The hub motors on the car in the OP run at ~24k RPM (faster than any production electric car AFAIK) and have a multistage planetary gearbox for reduction.
Pretty much all top Formula Student cars now use hub motors. Mainly for packaging reasons. Putting the motor in the unused space in the wheel means you can make a smaller chassis and have more space for wings and underbody aero.
Super capacitors are highly overrated by the general public. They really aren't that much better than lithium ion except for in a very narrow power/time bandwidth.
The comment I was responding to was lamenting the potentially slow speed of chemical reactions in batteries, so I recommended super capacitors specifically for the case where a higher rate of discharge is required. I agree lithium is potentially good enough there, I am merely speculating on solutions in the event that an ultra powerful vehicle really could exceed lithium’s capabilities.
As for the general public, I can’t say. I use super capacitors in the power system for my solar powered robot and I love them. Through that experience I have realized they have plenty of other applications.
The strangest thing to me is that apparently this material has been developed years ago, the video of a piece floating was uploaded 3 months ago, and apparently it's easy to produce more samples, but the papers still reads like they have been thrown together in less than a week. (English might not be their first language, but the presentation of the figures is also poor)
And it also seems like they haven't spent that time by doing high quality experiments. Surely if you have found a magic material that can change the world you would spend more effort than this on doing experiments and publishing a good paper as soon as possible.
The low quality video and poorly presented graphs are reminiscent of Victor Ninov's fraud.

Meh, it's just as easy to assume the opposite. Who has a stronger incentive to present themselves in the best possible light, a con artist, or a future noble prize winner with a patent on an earth-shattering technology? For the former, the credulity of the reader is necessary for the success of the con! For the latter, not so much, as the truth will be self evident in short order.
I read somewhere once that deliberately poor quality graphs are sometimes used so that readers cannot extract the precise values from them. This could be to obscure fake or real data.
This is true, but from personal experience, academics are terrible at including high quality images. My colleague would screenshot an image from some visualisation software and paste it in to her paper in MS Word. Then that image would get copied or screenshotted into a different word document, and so on, and the quality would deteriorate.
My wife is an academic and I often see her screenshoting to move an image from one document to another. Seems like a UI failure that the system can't detect this use case and move high quality backing images through the clipboard.
MacOS went full circle here at least with regards to text: In the new MacOS versions, if you screenshot text there's automatic OCR, so when you receive a screenshot of some text, you can copy it again!
It's non-trivial to implement that for something like SVG's, but if UI developers had anticipated this use case, we might have gotten a remedy with the introduction of raster graphics.
It seems weird because it's a big leap but big leaps do happen.
If it is a misrepresentation I'd be curious about the back story. I mean, even if it's not been knowingly done it will presumably seriously hurt the careers of the people involved; if it is knowingly I assume it will be "find a job in another field" kind of thing.
How could you suspect it wouldn't come out if it's knowingly? If un-knowingly how could you make an amazing claim like this without being absolutely sure of what's going on? If it's a "rush to publish" type thing - why wouldn't you make a big point of that in the paper (i.e. load it with caveats to the brim)? Plus this comment makes it sounds like it's been sat on for at least what seems to me like a fair amount of time.
All the options seem implausible but at the end of the day one of them must be the case. For the sake of everyone I'm pulling that it is what it says on the tin.
Imagine if Meta bought Reddit, pulled the need for ads and gave the volunteer moderators access to Meta's team of 50,000+ moderators. "You deal with the conversations and the messages from users, we'll take care of the taking down user content that is against the rules." Meta uses the content to train their AI models, removes API pricing (or reduces it greatly, no need to IPO and therefore no need to show revenue).
I think the original goal, and one I still support, is for websites to realize that they are better off with not showing the banners and just defaulting to "no". It's been surprising to me that an industry that has been somewhat obsessed with click latencies and getting users to content quickly are willing to annoy all their users for the extra income from personalized ads. The difference in value must be a lot.
When I tried waymo a month or two ago a remote "driver" took over. When we called the support center about it later they told us that it's not them literally taking over the controls, but only giving some additional guidance to the system.
