In controlled airspace you would be right... but these things are being pitched as suburban/urban commute options operating at low altitude where there's no ATC. That means they have to deal with birds, the GPS-shielding effects of tall buildings, wind tunnels created by the same tall structures and a whole lot more.

The automation of air-transport at 30,000 feet is a whole lot different to transport at a few hundred feet over a busy metropolis and where there may be buildings higher than t he craft itself.

You nailed it!

We've had VTOL passenger transport for decades now, in the form of tried and proven technology: helicopters.

Right now a bunch of startups are trying to reinvent the industry by claiming "carbon zero" and "autonomous" when we know:

1. the market is *very* limited (ie: where are all the helicopter-based flying taxi services?)
2. the tech isn't ready (current battery tech isn't up to the task)
3. we don't trust autonomous sytems on the road so why would be trust them in the air?
4. regulators are still many years away from approving such things in Western nations
5. there is zero mitigation available for GPS failure (or malicious attack) and eVTOL craft don't autorotate in the event of power faulure.

Call me in 10 years time and we'll reconsider.

Submission + - Dual standards at YouTube expose viewers to scams

NewtonsLaw writes: Almost everyone knows of at least one YouTube channel that has been unfairly demonetized or even entirely deleted by YouTube for nothing more than an allegation of "misleading" or "misinformation". The corporation claims that it does this to keep users of the platform safe.

However, this standard is almost never applied to advertisers, as witnessed by
this video which has also been running as a pre-roll/mid-roll ad recently and falsely offers access to Netflix, PrimeTV, Disney+ and Hulu without any monthly subscription.

Both the ad and the video that is played during the ad have been reported to @teamyoutube on X and via the report functions on the website but it continues to run and it will likely continue to do so until the advertiser has spent their budget.

This kind of hypocrisy does not endear the platform to its "partners" and also leaves happless users vulnerable to scams such as this.

The official response from @teamyoutube is simply that they investigate all reports — yet this is just the latest in a long list of ads for scam products such as free energy generators, drones that claim premium features but turn out to be toys and other products that are nothing like those being advertised.

Submission + - New charger could double the service-life of Li-Ion batteries 1

NewtonsLaw writes: Lithium-Ion (LI) batteries are the backbone of much of our modern technology. They're in our phones, our laptops, our smartwatches and even the EVs that are increasingly appearing on our roads. One of the problems with LI technolgy however, is the very finite life of those batteries.

In the case of an EV, the battery pack represents a very significant portion of the total price you pay when buying one. Right now, the life of EV batteries is generally considered to be at least eight years, under normal use. But what if that could be doubled — simply by changing the way those batteries are charged?

This announcement by researchers in Europe indicates that the service life (ie: the number of charg/discharge cycles) of LI batteries could be as much as doubled, through the use of a pulsed current charging technology.

The standard charge method for LI cells is to deliver a constant direct current (DC) until the voltage of the cell rises to around 4.2 volts, at which time the voltage is maintained at a constant level and the charge current allowed to fall off. Once the charge current reaches a predefined minimum level, the cell is considered charged.

The new pulsed current method does not use DC but instead opts to recharge by way of intermittent pulses of current. This is not a new charging technology although it's not the norm for LI cells. Pulsed current chargers have been used on older chemistries such as nickel-cadmium in order to reduce/eliminate the formation of dendrites that would otherwise create short-circuits or significantly increase the self-discharge rate. Applying this tech to recharging LI cells seems to be a significant game-changer, if the lab results are duplicated in "the real world (TM)"

Doubling the life of your EV's battery or even your smartphone's battery is no small thing.

You want a real indicator of inflation? Look at the cost of the good nearly every American buys to keep up with the Joneses, the latest and greatest cell phone from Apple and Samsung and accompanying plans from the major providers. Since Biden assumed office housing has tripled and they've gone from $300 phones to barely improved $1200 phones and both have sold like hotcakes despite virtually nobody being able to afford them meaning there is enough cash and credit [spendable money] floating around to buy them and inflation of at least as much.

IPhone 12 was launched in 2020, at a price of 799 USD. IPhone 15 was launched in 2023, at a price of....wait for it... 799 USD. The world of "let's make up facts" is very harmful for civil discourse and democracy.

Comment Since when? (Score 2) 19

YouTube doesn't seem to enforce its ban on downloads at all. I see *many* YT videos which include footage from other YT videos and the only way they got that was to download the video so as to include it in their own. One only has to look at they myriad of compilation "FAIL" videos to see this happening.

Even when the original creator files a DMCA claim against such videos, YT will often consider it "fair use" and not penalize the person who has clearly downloaded and then used that footage.

For YT to then come out claiming that it's against their TOS if AI systems do it is a bit rich.

High-speed rail emits roughly 1/4 of what a jet does per passenger mile. (Experimental ones even better). For cross-land travel, unless you are in an unavoidable hurry, it's the logical choice. So hop on the Greta Express choo choo! and sing fun woke songs with the wonderful diverse woke crowd. You may grow to like it, MAGAs.

Even less - the French TGV states that CO2 emissions per km per passenger is 3.2 g. For airplanes, a modern plane gives about 115 g of CO2 per passenger pr km. The French power mix is mostly nuclear, which would explain the low emissions.

Ya this is far more stupid than California decriminalizing theft under $990 or NYC ending bail for extremely serious violent felons.

But those Republicans!!

Bail should end in any case. Either, you should be in custody - e.g due to an ongoing investigation, flight danger, or being a danger to the public. If there is no good reason to keep you in jail, you shouldn't have to post bail.

As right as he is, Mr. Faury is very classy to say it.

He just doesn't want to be seen publicly gloating.

Of course, he's delighted with Boeing's blunders.

Worries about "the image of the industry" are nonsense. People won't stop flying.

Doubt it. Boeing is big enough that safety concerns reflect upon air traffic in general. Doors falling off in the middle of the air etc results in fewer passengers and reduces the demand for planes. What he'd want is a gradual decline in the attractiveness of Boeing vs Airbus, corruption scandals, strategic missteps, etc - not scandals related to accidents or quality,
