Re: Do electric aircraft have regenerative braking?
For some reason your post made me imagine them using the props as wind turbines while parked, letting them spin in the wind as it were. Put a smile on my face.

It wouldn't add much to the range per flight, but it would add to the longevity of the batteries making total ownership costs potentially much less for the operator. The batteries wouldn't need to dump large amounts of current over the short periods required on each takeoff, my reasoning for this is drones, if flown in normal mode batteries have a much longer lifespan than if they're flown in sport mode.
But I'm not just talking about the cryptography of service providers, GCHQ want all crypto provided in the UK to be compromised, be it Joe public, universities or companies. When any of the above can and do work on projects which fall under the umbrella of "national security interests" it shows how daft the idea of compromised crypto is when they say that they need compromised crypto for national security but they also need strong crypto for national security. There's a logical fallacy in there about snakes eating their own tails.
Downvoted for being against pedophillia? Wow, a new low for the register comments section.
To be perfectly clear the guy is a sex offence waiting to happen. He's even for necrophillia and sex with animals. Downvote all you like, he shouldn't be on the streets nevermind helming an organisation.
Anyone else notice that the exhaust from one of the rocket motors changed to a bright green flame many seconds before the BOOM?
You could get such a green coloured flame by burning copper (an unlikely material in a high temp rocket motor) or by burning boron (a very likely material given its much higher melting point and other features) either way it suggests that the motor was in effect "eating itself" prior to the fateful landing.
That's rather disingenuous, I never said that the Chinese government is not sponsoring industrial espionage, they quite blatantly are. Just like every other country to varying degrees of hypocrisy.
I am pointing out how the previous commenters arguments against Huawei fall flat on their face when not seen through a haze of partizan and I dare to say it, racist anti-chinese sentiment.
The Chinese government does not equate to the Chinese people, nor Chinese companies.
If ignorance is bliss then you must be one very happy camper.
Lets go through your list of perceived grips one by one.
"Huawei is the private enterprise of the PLA, even more willing to follow Chinese laws forcing every private company to share everything with the tyrannical CCP regime" - You see that part where you wrote Chinese laws? You get what a law is right? It's non-negotiable, You don't want to go to jail, you follow the law of the land. There is no choice. Also pretty much every major company that wants to operate or trade in China must accept some percentage of government ownership. This does not make them a "private enterprise of the PLA, Foxconn ring any bells? how come you aren't griping about Apple?
Espionage - Huawei opened their source code to the British government for inspection, sure their source was shitty, but can you guess what wasn't found? I'll give you a hint.... nefarious espionage code. Call me back when Cisco is willing to do the same.
IP theft - Hmm you haven't actually checked on this have you? Guess who owns a metric shit-ton of 5G patents, if you guessed Huawei then have a cookie they're so far advanced in 5G they can make better chips cheaper than their competition, hell they helped write the 5G standard. Now guess who stands to benefit if Western countries can use those patents without the need to pay royalties to Huawei.
loss of competitive power and knowledge - Ahh, now we see the crux of the matter "They're making more money than us and they're smarter than us!!" Jealousy and a feeling of inferiority, those great drivers of global politics and many other bad decisions.
Inconsistent viscosity might cause imperfections in a frozen surface which may not be as big an issue when it's a liquid in motion. Presuming that the "thicker" parts of the liquid would be held against the outside edge by the spin.
(I'm not an expert by any means, that is just my guess and could very well be wrong)
I expect they're probably using a variety of 7075 Aluminium alloy (Aluminum for the FREEDOM!!!!! folk) which has a slightly higher thermal expansion then a lot of steels. But even so, I've seen it used as components in jet turbine housings and mounts and it sure didn't get anywhere near 13mm of expansion while in use, nevermind on a hot summer day.
I suppose they could be talking about total expansion by volume as opposed to directional. Would be a daft way to phrase it though.
"During the day, the temperature on the Red Planet can fluctuate by up to 38°C. The added heat can cause the metal on Perseverance's robotic arm to expand and contract by up to 13 millimetres"
Expansion of 13 millimeters over a temperature differential of just 38°C? doesn't that seem a little extreme? I would expect a deviation of around 1.3 mm not 1.3 cm.
Nope, not the pacific. Neither the Japanese nor I want him washing up here on the shores of Japan. Amusing as the thought of him being chewed up and shat out by Godzilla might be, would anyone really be able to tell the difference? A huge pile of steaming shite is a huge pile of steaming shite however you choose to look at it.
The majority of Foxconn factories are in mainland China, bankrolled, part controlled and protected against human rights investigation by the PRC. You can bet your ass that all data and designs that flow from the headquarters in Taiwan to the factories in china do so via the PRC.
Wrong China? Show me how I'm wrong. IF you can.
I seem to recall that Apple's devices are made by foxconn, a known human rights abuser and part state owned/controlled, in China. Curious as to when they'll be banned and wether or not the republican party and Trump could even survive trying to ban them (I envision Washington taking on a striking resemblance to a Romero movie, with the government barricaded in the white house surrounded by black turtleneck wearing zombies).
@trevorde some might suggest that this is the current status of ai.
Cognitive abilities ⩽ a 3 year old, can't make a correct decision on its own regardless of the size of its training set, shows extreme bias, gets confused when asked to distinguish between a picture of a dog and a duck. Certainly sounds like most of my prior bosses.
Don't worry, the world hasn't gone topsy turvy. Like most who are obscenely rich or hold power over the peons he couldn't give a flying zuck about the privacy concerns of the masses, what worries him is that his own personal communications could be compromised. That's why he wants this nipped in the bud, any fallout that benefits us normal folk is purely accidental.
Earth also has several "moonlets", asteroids locked in Lagrangian orbits. So not so much with the orbital clearance as a category for planethood. Also how does clearing an orbit work for planethood when you consider planetary rings? Is Saturn not a planet then? Demoting Pluto was arbitrary and capricious, which is why they waited until most of those present went to lunch before forwarding the motion.
It gets shared around the station for them to masturbate over. Whereas common folk cannot fly near houses or over crowded parks and beaches, plod can and do. In the process their drones seem to spend a lot of time loitering in areas with the prettiest/most skimpily dressed females for some reason...
Funny you should mention a fridge magnet as an authentication device.
I used To work for an ISP and the pencil botherers decided that every internal door should have magswipe security which doubled as timecards and basic workplace snooping. My domain in the server room and "control suite" already had good old fashioned pin number locks.
Cue much frustration and general gnashing of teeth as people forgot their ID cards at home or on their desks.
Until some scruffy intern in the web design department discovered that using any magnet from any of the memo boards liberally distributed around the company would open any door with a quick swipe down the card slot.
Bloody expensive but about as secure as a politicians moral compass.
Landing, "coming down again", isn't as easy as you'd expect. To increase your orbit you add velocity, to decrease you slow your velocity. What happens when gravity effects the rate of descent? The capsule gains velocity. "Coming down again" might actually be more difficult (relatively speaking) than going up.
They beat you to it. There is a huge supply chain out there selling "magic rocks" from £30 and upwards each, while claiming they'll cure everything from full blown aids to poltergeist. They are unsurprisingly indistinguishable from the contents of bags of large quartz gravel you'd normally find in any garden center or DIY store at around £15 for a 20lb bag.
Reminds me of a place I once worked in Belfast. All the staff were looking forward to the usual Christmas bonus only to be told that there wasn't enough to go round that year (which came as a surprise to everyone considering the company had done rather better than normal). When everyone returned from the Christmas period what did we all discover? Both bosses had acquired brand new and fully optioned VW Passats. Purely by coincidence of course.... bloody cockwombles.
To me the obvious solution is that the UK is (like it or not) Part of the European continent even if it leaves the union and is therefore entitled to .eu domains (for an understanding of EUrope as opposed to European Union), of course that could change if all the vote leave folks get their oars out and start furiously paddling the UK towards open ocean whilst yelling "Brexit means Brexit!!"
Personally I couldn't give a toss outside of the bemusement and amusement factors, I saw this shit show coming several years ago and buggered of to live in Japan with both a UK and an Irish passport in hand.
