Re: Simulated Inertia

An external clock isn't needed - the grid can provide that. What is needed is to vary the phase of the current fed to the grid according to the frequency of the voltage received from the grid - just as the armature of a real alternator would.

If the grid is running slow, current leads voltage. If it's fast, current lags voltage.

This effect can be powered by local batteries which can also be used for storage.

The algorithm should be trivial for any competent DSP engineer

Interchangeable Parts?

The whole back-to-office thing reeks of the management anti-pattern that "personnel" are "resources" - fungible, interchangeable parts that can be moved or ordered around without consequence.

The survey says that 1/3 are seriously considering quitting, which means that 5%-10% actually will. But quitting is easier for those whose talents are most in demand - the ones managers can least afford to lose.

Will managers realise this? Some will, most won't. But you can help them to realise it, especially if you are "top talent" yourself.

I don't know if they changed their number or went out of business, but the calls stopped.

Boffins explore cell signals as potential GPS alternative

Cell transmissions do include timing data and location data - you just have to interpret it. There is a network-wide timebase transmitted in the control channels (4G and 5G use these to share access) and the pilot channel will include a unique cell ID which can be used to find it on a map.

Using the time delay part of neighbour cell measurements of three cells can give location to within a few metres - technology that has been available since the 2G days.

The networks know where you are - they always have. Anyone who can access your neighbour cell measurements does.

Re: ARMed and Ubiquitous

Mistake, no. "Could-have-been?" Absolutely so!

Of all the quirky and oddball things I remember in my forty-mumble year career in IT and telecoms, ARM is the most incredibly successful - and the reason it succeeded against incredible odds is because it was so outrageously better than the competition

ARM is the hardware equivalent of Linux in that regard. It came from a nowhere budget and it is driving the corporate competition slowly but surely to oblivion

Of course my own memories are coloured by a short stint working in that old waterworks. Good times

ARMed and Ubiquitous

The part of the story you've missed is that the project that Furber and Wilson worked on in a downstairs room in the old Fulbourn Road waterworks turned out to be the dominant CPU for ... well, pretty much anything with a battery.

Which means phones. So. Many. Phones.

EV sales hit speed bump as drivers unplug from the electric dream

I live in rural Ireland with no charging infrastructure nearby - except the electricity supply to the premises.

We have a cheap EV *and* one of those secondhand diesels: a 4WD Duster. The Duster does about 5% of our household miles, because the EV saves so much money

Since I commute we needed two cars anyway, but diesel compared to cheap-rate electricity is a no-brainer. It really is

The only reason we would not have an EV is if we couldn't charge overnight at home

Re: New cars are expensive

If you can charge at home, your budget for car payments will be offset by a reduction in fuel bills. How much impact that makes depends on your mileage, but the high-mileage cars are the ones we want to go electric first.

For my commute the monthly car payment would have been (I paid cash) less than my monthly payments for diesel. It was a no-brainer to replace my ancient Ford Focus with a new EV.

This. This here.

If our lords and masters want EV adoption, they need to provide cheap AC charging in the places where people park overnight.

Overnight AC charging is better for the grid (low demand, at a time when there is surplus capacity) better for the batteries (because slow) and cheaper (because AC chargers are cheap and don't require enormous infrastructure.)

All this idea of more and faster DC chargers is distraction. EVs should be charged while their owners sleep and the grid is idle.

I have owned an EV for years, but I wouldn't own one if I couldn't plug in overnight.

Re: Corporate Culture

The company I work for (and, incidentally, one of the nicest employers I've ever worked for in 40+ years of mostly contracting) has an explicit "speak up culture" that should catch this sort of thing.

We also have a system of security emails and other communication designed to educate people in how to spot phishing and the like.

Re: The creative maker ... has never had it so good

The Arduino chips are programmed in C, but PIC devices are in assembler. If you really want to go low level, gadgets like PAL/GAL devices are still available.

The last assembler I used was Blackfin - and I was paid to do it.

Re: The creative maker ... has never had it so good

I disagree. The maker movement is active and growing and feeding into the amateur radio community. Yes, you can build using modules, or you can combine software with Pi or Arduino, or even construct with discrete components.

Thanks to Internet, webpages, YouTube and social media, constructor knowledge and knowledgeable advice is easy to access, and projects on GitHub and the like allow makers to cooperate on things far outside the scope of one hobbyist.

Car industry pleads for delay to post-Brexit tariffs on EVs

Re: I'll be sticking with petrol (or diesel) for my next car.

The battery on mine is the same as the Leaf. And yes, I know Leaf owners who have had individual battery modules replaced.

Re: I'll be sticking with petrol (or diesel) for my next car.

Agreed. There should be cheap (=domestic night rate) AC charging everywhere cars are left overnight. That is the missing piece. Get onto your politicians, your local council, your landlord if you have one. That is the blocker for the EV adoption that the governments want.

Fast charging is not the answer: it wears the battery, it loads the grid at a time when it is already loaded, and the chargers are expensive. Overnight AC charging is the answer, and it needs to be ubiquitous if EVs are going to be widely adopted.

Re: I'll be sticking with petrol (or diesel) for my next car.

The point is that a module failure is not a replacement battery. It is a replacement module. The battery on my EV is 96 modules. The overall battery costs about 8000 euros, so an individual module ought to cost 80. In real life, motor parts don't work like that, but it's certainnly not thousands.

The overall battery doesn't fail, it fades away. The range goes down. If my car has 75% of the range at 100,000 miles, that is not "conked out," it's just less range. If it has 25% of the range at 500,000 miles, that will also not be "conked out," either. And, if your local battery recycler won't pay you for the battery, find another one. Lithium is valuable and is going to get more valuable as time goes by. You don't pay to have lead-acid batteries taken away, do you?

I am not sure exactly of your anti-pollution measures in your power stations, but it's a lot easier to fit a scrubber to a power station than to a Kia diesel. But a quick Google talks about a 74% reduction in NOx emissions from Britain's energy sector: https://www.gov.uk/government/statistics/emissions-of-air-pollutants/emissions-of-air-pollutants-in-the-uk-nitrogen-oxides-nox

Re: I'll be sticking with petrol (or diesel) for my next car.

Do you have a source for that efficiency of a petrol engine?

Consider this: burning a litre of petrol gives about 9.5kWh of thermal energy -- source https://www.engineeringtoolbox.com/fuels-higher-calorific-values-d_169.html

So my EV was built with a 40kWh battery that gives about 200 miles range: 5 miles per kWh. If your car can get 40% of the 9.5kWh out of a litre of petrol, and is not harder to push down the road than my EV, then it should get at least 19 miles per litre -- more if my EV is less than 100% efficient -- or 85 1/2 miles per gallon. Does it?

Re: Sacrifice all to the God

If you want to see a really compromised supply chain, take a look at where your fossil fuels come from.

The world has suffered decades of oil wars. Time for a change.

Re: I'll be sticking with petrol (or diesel) for my next car.

There are a couple of standard pieces of anti-EV FUD in there.

The first is "batteries conk out." EV batteries are modular and, if a battery module fails, it can be replaced for hundreds rather than thousands. Compare your fossil-powered engine, where the failure of a piston ring will necessitate lots of labour to rebuild the engine, or a complete new engine for a similar price to a complete new EV battery pack.

The failure mode that is happening with EV batteries is wear: which means their capacity and so range reduces. So your EV which previously did 200 miles now only does 190 miles (about what has happened to mine after 50,000 miles and 5 years of driving.) But even when it has been driven 100s of 1000s of miles and is reduced to 100 miles range, it is still useful to someone. When your diesel Kia has a worn-out engine it will be scrap value.

The second piece of FUD is "move the emissions from my tail pipe to a gas fired power station." Firstly the gas-fired power station extracts far more work from a given amount of fuel than your car ever will, because there are no requirements for a power-to-weight ratio in a fixed power station. Secondly the emissions that are giving little Timmy next door his asthma attacks are best moved to the power station, where scrubbers can remove the nitrogen oxides from the exhaust in a way your car never can -- that power-to-weight ratio again.

But the last point is the big one. If you buy a brand new diesel car, it will spend the next few decades being powered by diesel. If you buy a brand new EV the fuel used will change according to the fuel mix used for the grid. So, even if it is fossil-powered today, who is to say it will still be fossil-powered in 20 years?

There are real problems with widespread EV adoption -- lack of affordable overnight charging is the biggest one -- but most of what you've read about EVs is FUD. Check it first!

Re: Why the down vote?

Sorry, no.

Yes, the amplification is done optically, typically using a laser to provide the "pump" energy for the amplification -- but the laser is still powered electrically, via long wires.

Since the induction that makes major solar storms so destructive involves distortion of the Earth's magnetic field, it affects anything on or near the Earth's surface: including overhead and buried cables, and cables at the bottom of the ocean.

Long wires are vulnerable.

Re: Why the down vote?

Long distance fibre relies on repeaters, which are powered by copper powerlines that run alongside the fibre itself. Those copper powerlines are long wires.

Also, there are a lot of exchanges that are served by fibre but still use copper for the "last mile" connection. Again, long wires.

Fibre itself is not affected, but the infrastructure is. Replacing every 10km repeater on a transatlantic fibre is essentially the same as re-laying the thing. And, if the relay cabinet on your street corner is fried by its power lines, the signalling technology is irrelevant.

Hopefully, those of us wih HF radios, UPS and generators will have the good sense to unplug the antennas.

Re: Satellites are a good idea if:

Any major solar event that knocks out satellites is also likely to kill anything connected to a long wire -- which means POTS phones and exchanges.

(Icon for the other event that has a similar result.)
