tomo; in your post about V2G you said:
"Even though it's been talked about for what, 20 years+, there is still no agreed, widely recognised standard for grid synchronisation that allows for net metering"
I am probably misunderstanding but isn't this well-established for roof-top solar?

On that subject, am I correct that domestic solar shuts down during a power outage for H&S reasons unless there's extra kit fitted which isolates the house from the mains, allowing it to continue running on solar - if it's working, obvs. Siad extra kit is not cheap, aiui.

Battery siphoning eh?

Got to expect some Darwinian action in that department.

Bah... timer timed...

Hopkins is indeed one of my favourite characters in the FDR regime. He was a cunning and resourceful operator. Without revisiting the rabbit hole of his rise through the New Deal and links to Comintern and associates who were more open about their ideological allegiances - his (undisputed) reaction to a Major Jordan opening cases of nuclear documents, engineering parts and nuclear material samples in mislabelled crates which were being transported as air freight under Hopkins's personal mandate (as FDR's #2 / deputy) to was what really got my attention. When you compare Hopkins's travel in both directions between USA and USSR to other travellers and events, circumstances indicate he was a very important player. Any discussion of Hopkins triggers evasiveness from US establishment sources - they are likely quite relieved that he expired when he did.

tomo,
That "Connection Guide" was an impressive document. Another scheme that reminds me of Terry Gilliam's Miracle of Flight, where one person invents in-flight movies, another invents the departure lounge, etc., but still nobody had invented the aeroplane. On p22 we have a list of "Impacts", none of which are addressed in the rest of the doc (which I admit I only skimmed), but it includes killer items like over-voltage and overheating. Tsk, tsk. Never mind. Here are all the forms to fill in to connect up.

Another little thought with the V2G, your neighbour may not be able to siphon your tank. He can only do it if the wire to his property is the same phase as the wire to yours. A more sure way would be for him to park his car next to yours, hook up a lead, and "siphon" directly...

And all this charging and discharging has to sap battery capacity. Not such a big deal with a power wall (or whatever), but quite important if your car's range matters to you.

On Harry Hopkins, I'm pretty sure you've pointed me at him previously. I read around a little and came away with the feeling that he was more of a Talleyrand type — an adroit survivor — than a zealot.

Whoever started the rot, it would be nice to see it end.

The V2G sums are simply mad for non emergency power storage - what you get paid for electrons as a small producer feeding in is simply an insulting amount of money + a piffling RoI. If the grid is sagging to the point that EVs are called on, it seems likely that it's in a state where clunk, silence + darkness are not far away?

Even though it's been talked about for what, 20 years+, there is still no agreed, widely recognised standard for grid synchronisation that allows for net metering and seamless magic smoke and bang/magic smoke free near immediate connection and safe reverse feeding the grid.

I'd wager it (V2G) will go into Smart Meter territory sooner rather than later....

The circuit protection in that car Cadogan was messing with seems likely to be a core balanced RCD style device which are in my experience discombobulated often by hefty switching power supplies (VFDs, welders) and motor starting. - the car inverter is usually 3 phase VFD - so I wonder if the V2G function depends on another, separate single phase crude inverter to do AC power from the EV's battery pack? I doubt that running an unbalanced 3ph traction inverter to provide single phase is sensible ...


Robert,

FDR's administration was noted for a mad sprouting of multi-letter agencies and penetrated by Stalin's agents at all levels... A read around the career trajectory of the airbrushed out Harry Hopkins (and others) is eye opening stuff ....

MikeHig,

I think it's a pipe dream for longer than that, as is a general uptake of BEVs. The whole thing is science fiction. A few EVs in the street is one thing, but having one in every house is going to require a massive rework of the cabling and equipment. V2G could help a bit, but by adding a lot of extra complexity; weird to be "siphoning your neighbour's tank" so you can go for a drive. How's the electricity bill going to read?

It's an interesting thought about hooking up an "extension lead" between their V2L and home without isolating the home from the grid (presumably during a blackout). People have probably already run into this with portable generators. Not sure what would happen -- just more async inverter noise on the grid, or fry the inverter itself?

I suppose a sensible person would avoid the issue by just running a conventional extension lead to the fridge itself (or whatever) rather than power the whole house with a male-to-male extension lead to a wall socket.


tomo,
The reaction to Durkin's first effort probably did quite a lot to improve his second. Even if his first had been great, it wouldn't have done much to stop the rise of the monster. His second just might help speed its fall.


Quite enjoyed the John Anderson conversation with Richard Epstein (from mid '22) on the Roe vs. Wade overturn in the US. Went nicely into the creeping federalism in the USA (quite familiar with it in Aus. too). He placed the start of the rot further back than I'd have expected, at the FDR regime, when a lot of today's federal "cartels" were put in place.

My guess is that Australia was in its usual position, following about 20 years behind.

"Tom Nelson + Martin Durkin"

Sounds like a massive OFCOM complaint, right there.
