This is getting silly. Many people (at least in the UK) have barely settled in with widescreen HD, and some channels are still broadcasting only in SD, yet here we have the industry pushing for even higher resolution. And where is the bandwidth going to come from? Already, the UK's Freeview system is struggling to find room for a handful of 1080 channels, so where's it all going to fit?
At least it ain't as plug-ugly as the Multipla, the designer of which must surely have been on a quest to deliberately disgust the public. And it's better-looking than the latest Nissan Juke, which resembles one of those horrors from the deepest parts of the ocean.
A few random thoughts, mostly negative.
I saw a video of the software in action yesterday, and it showed how the car detects a cyclist. Apparently it knows the cyclist is about to move into the traffic stream 'by seeing that the rider has put out his hand'. WOW, when does that happen? Over here, cyclist think they own the road and just hurtle across lanes with no warning whatsoever.
Then the video shows the Noddy car snuggling in behind the bike - which was going about 10 mph. For safety reasons, the car would not pass the bike. Oh great. Even if it tried, it couldn't, because here in the UK our ultra safety-conscious councils have put central islands every 100 yards to stop overtaking, 'cos it's bad bad bad, see?
I find that the anti-car brigade always support these noddy cars, as they see them as a way of bringing our roads to a grinding halt, or at least imposing ludicrously low speed limits.
Final thought. This idea will only work properly when our roads have been filled with sensors. No doubt in the meantime (in the interest of 'safety'), these cars will be given every unfair advantage over conventional cars - they will be able to use bus lanes, pool lanes and park for free. Don't you just love it?
I think most of us could see this coming a mile off. There will always be people (and there are indeed millions) who cannot and will not put their cyber tools aside when driving or even crossing a busy street. They cannot bear to be disconnected for an instant. If the lady wasn't using them, she should have removed them, simple.
Battery tech not good enough
The battery technology simply isn't up to the job. Any scientist in the field will tell you that storing electricity is problematical and the energy density nowhere near that of fossil-fuel. Add to that the tendency for Lithium cells to behave badly at low (or high!) temperatures and you have major problems.
If the EV ever gains mass public acceptance, expect to see our city streets and motorways littered with dead cars and desperate travellers.
Re: Writer was intent on high risk of failure
It's the battery technology, as usual. Lithioum cells (especially high-power types) are known to be affected by temperature and any vehicle that uses them is going to suffer in the manner described in the article. In my view EV's are simply not up to the type of mixed driving that most people are accustomed to.
If ever we adopt EV's on a mass scale, I can see our city streets and motorways littered with dead cars and despairing drivers.
Re: Crud generators.
The difference is that PLT devices prevent innocent radio amateurs and short wave listeners from persuing their hobby, but short wave listeners and radio amateurs don't stop computer users from enjoying their activities. PLT is by definition destructive and selfish. A kind of 'I'm alright Jack' device.
It doesn't matter which system they use - ALL homeplug/PLT devices work by injecting large amounts of radio frequency noise onto the domestic wiring, and ALL cause large-area radio interference. It's only about a year since my hobby (amateur radio) was completely stopped by just one pair of these devices installed along the road. Luckily, the fellow was genuinely horrified when I demonstrated what his PLT's were doing and he stopped using them. These things need banning, and quick.
Ho-hum - another day, another scare story from the swivel-eyed 'the sky is falling' warmist brigade. I've lost count of the number of lies and half-truths they've tried to get away with over the years, from islands disappearing under the sea (demonstrably not true) and those 'glaciers that would be no more within 30 years', which they later admitted was utter fiction.
That graph only goes back 200 years! and look, there's less than one degree C rise over those 200 years. And The idea that Global Warming is not happening is a bit of a strw man, is it not? Surely the big challenge is 'is it man-made'?
Regulating the regulators?
"Ah, I forgot, the Conservative party." - AC.
Actually Ofcom was set up under Labour, and this whole thing (the reports commission and their suppression) all happened under Labour.
At least some Coalition MP's and Ministers are showing *some* interest.
Lies and Greed.
I'm currently not suffering from PLT noise (just SMPS etc), but a while ago I found the entire spectrum from about 4 MHz to 20 Mhz was unusable due to some very strong whining-type noises which I recognised as PLT.
It was strong enough to knock out all but the strongest BC stations, so the utilities and such-like stood no chance - they were completely buried.
Once I had found out where the noise was coming from, I realised I vaguely knew the guy who lived there and I gave him a knock.
He confirmed that he had recently bought a pair of PLA's (not Comtrend), so I asked him if he would come to my house (about 50 yards away) to see the problem.
Once he saw (and heard) the amount of noise on my radios, he was horrified and told me he would wire the system as soon as possible. He turned off his PLA's the same afternoon.
He was a reasonable bloke but sadly many are not and dig in their heels, often seeming to take delight in the trouble they are causing. Such is modern society.
If these things - which breach every rule in the EMC book - were not on the market, none of this trouble would be happening. Comtrend, the other makers and OFCOM have brought this about through their lies and greed.
AC - I know it can be difficult getting data from one place to another in your home. But PLT is not the alternative. It doesn't exist, not in any legal form, anyway. Just imagine that OFCOM did its job and stopped these devices from being imported, manufactured and sold in the UK. What would you have done?
Persevered? Run the CAT5 as best you could?
Anonymous Coward says:
"The guys complaining listen to wide band AM broadcasts in between the amateur bands on crappy domestic receivers with rf and af stages as wide as barn doors."
No we don't, and your comments display a worrying ignorance. Many of us use top-flight receivers and have adopted the use of loop antennas and phase-out devices to minimise noise. This is nothing to do with receiver front-ends or filters. You have obviously never suffered with s9++ of whining data-noise which is obliterating not only international utility comms, but strong SW broadcast signals as well. No amount of dynamic range, filtering or indeed prayers to God Almighty will make any difference.
There's only so much noise reduction can do. The fact is that these PLT devices are radiating high levels of noise from the local mains wiring and breaking the EMC laws by up to 39dB. That's a huge amount by anyone's reckoning. It is illegal and our UK regulator OFCOM tried to cover it up. Now we need action.
In response to the ignorant and selfish Andy97 and GatesFanbois. Since when did radio amateurs use wax discs? I'm afraid your childish posts just reveal your lack of knowledge. AR is not an old-fashioned hobby. Many of us use cutting-edge digital techniques and digital signal processing is in common usage. Communication via satellite and moonbounce is in regular usage.
We have rules and laws which were put in place to keep the radio spectrum clean, and these need to be obeyed. Ofcom is the UK regulator but they failed to enforce the rules, thus allowing the widespread pollution of the RF spectrum to take place.
It doesn't matter how many people are affected, it matters that the law is being openly broken.
Perhaps you wouldn't mind being told by the police that they weren't going to investigate the burglary of your home because hey, only one person was affected and anyway the burglars only took your TV and a few quid?
Ofcom is an evidence-based regulator that suppressed evidence and refused to regulate. The interference from these devices can radiate over several hundred yards and make weak-signal comms impossible. Closer in it swamps even strong signals. You only need one pair of these things in your village to wreck your radio listening.
The EMC reports that Ofcom have now been forced to disclose prove that these PLT devices vastly breach the rules and laws regarding EMC compliance, but Ofcom chose to suppress these reports and deny everything.
They lied to the public, to MPs, to Ministers and to MEPs in the process.
Ofcom is not well-liked by our current government, and I hope strong action is taken to bring those responsible to justice.
Enforce the law!
ALEX KING - This is not a matter of 'who is the biggest', it is 'who is legal?', and the PLT devices are NOT, Amateur Radio IS. The devices do not comply with interference legislation (by a huge amount!), and so they should be removed from the market.
Secondly, you show your ignorance by suggesting that Ham Radio is 'a throwback'. Modern amateur radio uses all kinds of technology including digital data comms and weak-signal detection schemes you wouldn'r begin to understand, so let's have less of the insults. This is about upholding the law, not 'who's the biggest'.
'It's only a hobby!'
In reply to Duckfest and his 'who cares?' post.
What is the point of Amateur Radio? Well, it's a technical hobby that one can learn from. We have to take exams to do it. What's the point of fishing, football, horse racing or snooker? If you were fishing one day and I came along and poured poison into the lake, you would be annoyed, and move to another lake. But then if I followed you around and poisoned ALL the lakes you'd be after my neck, because I'd put an end to your hobby.
I've learned a huge amount since I got my licence in 1984 (when I was 31, not a pensioner), are we to deny the same valuable experience to young people now, simply so manufacturers can make a buck, and lazy people don't have to run a cable? The whole thing is a disaster. If I have to give up my radio activities I honestly don't know what I'd do.
How do you fancy this?
An awful lot of people go to watch football every week, so I wonder how they would like it if I turned up in a JCB and drove all over the pitch, preventing the game from taking place? Every week. And if they moved to a different ground, there'd be someone already there churning that one up. Every week. End of football. After all it's only a pastime, isn't it?
I bet they'd change their tune then.
And Amateur Radio has brought forth many advances in weak-signal techniques that are now used across the world in comms, space and molecular research, but this selfish technology will kill it stone dead.
It's a fake, I tell ye!
You'll never get anywhere with the conspiracy nuts. Even if you showed them hi-def images of the American Flag sticking out of the surface, they'd just say it's a fake. Forget them, we all know they landed.
