Re: And this is going to solve CO2 problems how?
Well since the carbon is captured into the lignodes... they simply plant more trees, which will therefore continue to absorb more carbon dioxide.

Lithium isn't the only available battery technology, it might be the best - but not all vehicles need the best possible battery technology.
I can see vehicles which are traditionally a "second car" being fitted with alternative battery technologies, or even the choice of technologies at different costs when a car is purchased (or the battery replaced - and given that warranties range between 100 and 150 thousand miles, that's about the time you'd normally replace an engine anyway)
The lower energy density of H will mean frequent top ups* ... *it would only need to go as far as battery can manage on a good day and cost the same, consumer
Well, I'm not sure - one of the advantages of the battery is that I can choose to never leave home with anything less than a full tank. H2 is back to the petrol station model, but with a harder to handle product.
Where do you come up with the 1% figure:
"The argument that we've started with electric so we should/must only carry on with that doesn’t carry much weight when the installed capacity is maybe 1% of requirements come the next decade."
BEVs are already more than 1% of the UK car fleet, and almost all of the remaining infra already exists, because it uses existing infrastructure. The national grid says "There is definitely enough energy and the grid can cope easily."

There will need to be more high speed hubs, and more devices at each one... but we have twenty to thirty years to build that out as the demand increases. If you ban sales of ICE cars today that doesn't mean everything is electric tomorrow.
Agree - there isn't a single solution for everything... I don't see the risks and complications of an H2EV being worth the limited benefits for cars/vans - the arithmetic changes for HGVs, they can afford the complexities of storage, and could store *so* much that they'd be able to deal with a relatively weak supply chain.
For basically any car the issue isn't max single stop range, it's either speed of charge *or* continuous charging for those rare long journeys (maybe a handful each year).
I'd like to see some battery standardisation, so that you can rent an additional battery occasionally, whether that's Li based, AlAir based, or something else, plug it in and boost range for that trip.
Maybe have it "spare wheel" sized, since so many cars are doing away with the spare wheel... yes I know that's a variety of sizes, but it's not that many really.
The one thing that is absolutely clear to me is that direct combustion is a piss poor way to provide motive power - even moving to hydrogen you still generate various nox-ious gases, and the efficiency is substantially worse than fuel cells.
"Norway should be used as a great example of how to do this stuff. Almost every village that has a supermarket and a filling station also have at least 2 DC chargers."
Perhaps more importantly they are mandating that all car parks should at least have the routing for cables to provide AC charging to every spot (they don't yet have to install all the cable, but the routing has to be available). That immediately reduces the dependency on fuel station style charging.
Whilst regulations don't *require* you to take a break in a smaller vehicle... it's still sensible to do so.
Taking regular short breaks is a mechanism to reduce fatigue and increase safety, failure to do so should be considered careless driving.
BEVs are far more effective than you (who I assume is talking from a place of not having one) realise.
I have an MGZS, it (just about) fits my wheelchair and family, and is pre facelift - so "only" has a range of 174mi range (WLTP), which I normally consider to be about 140, though I have done a trip to my in-laws and back without recharging - that's a touch over 160 (I normally take a five minute "volt and bolt" to leave a little extra wiggle room, but didn't on this occasion).
But the number of times in a year we use a public charger is so small it can be counted without even resorting to toes - and a couple of those have been destination chargers, so taking exactly zero time out of our day. It makes the six hour journey to my parents about one hour longer, but *much* easier and more relaxing.
There will be a few travelling salespeople who do silly miles each and every day, but they really are very rare - and that's where something less difficult to handle (like an Al/Air pack) could really come into its own. It's not particularly efficient, but neither is H2. Compared with H2 it's trivial to handle and transport.
Or of course battery swap stations for those users - who are probably either leasing or fleet users anyway.
I can see a role for lorries, but for vans and smaller you're right - DC charging for the relatively small number of long journeys is a better approach than hydrogen - there might even be an intermediate technology, something like Al/Air as a safe and easy "extender" with similar energy efficiency to hydrogen but without the storage/transport issues of hydrogen
Yep - I'm holding off replacing the wife's iDevice 8 until the iDevice 7 or 6 starts to fail in the hands of the offspring. The flexibility it allows is one of the major reasons I decoupled telephony contracts from telephony hardware a long while ago.
We used to upgrade (and pass down) one phone every 18 ish months, but it's been a little over two years since the last upgrade (which was feature driven), and no real sign of needing to upgrade any time soon - even then I might also just opt to replace the battery in the 6 (assuming that's what starts to give out).
My last foray into EMC testing was fun. EMC testing facility was basically a small wooden building in the middle of a field - with a rather long electrical supply cable.
Server had three ~1200W (I think) PSUs, and because it was "just testing" we had them all plugged into a single four way extension.
About to do all the zappy stuff to the box, which had been put in the back of my car the previous day, and so we plugged in the four bank. The inrush from those PSUs turned all the lights out for about half a second.
Fortunately the chassis and PSUs were already certified, so we just decided to ignore that...
Oh I don't hate it - it's not worth the effort.
Of course I call it soccer whenever I have to refer to it, and generally treat it with the disdain it* deserves... but hate is going too far.
* Commercial soccer that is. I have nothing against school/community based sports**.
** No using a golf bat on a golf court doesn't count as sport.
Why not just put tags in the back of everyone's shirt and track that and the ball - no AI required...
If player's Z axis location is further forward than all but one of the opposition when the ball air pressure spikes (because it's being kicked) then flag potential offside - with an indicator on screen as to the player in question and the ball at moment of pressure spike.
If they fix the system and reimburse those affected... I'm all for doing it in a speedy way, rather than having it drag out over months.
But despite not being an admission of guilt, it should also not be a permanent immunity... Anything else they do and this should be lumped back on top.

Its martian origin was confirmed by pyroxene analyses (Fe/Mn ratios)and noble gas measurements that match measurements of the martian atmosphere. This meteorite is a breccia with a basaltic bulk composition and initially classified as a porphyritic basaltic monomict breccia clasts containing a wide variety of textures and include gabbros, quenched melts, and oxide rich reaction spherules. Other portions of the breccia contain plutonic lithic clasts such as monzonites and norites, basalts, and impact melt clasts. This is a very heterogeneous breccia!
Initial studies of NWA 7034 determined that the meteorite's bulk composition coincides with the composition of the average martian crust determined from mission data. This bulk composition also matches some of the rocks and soils measured in Gusev Crater by the Mars Exploration Rovers (MER) and in fact, this meteorite represents the strongest link between a martian meteorite and the geochemistry of the martian surface determined by remote sensing.
You choose your polling interval according to the length of time you are willing to live with the array in a degraded state - I'd suggest that 12 hours is too long for critical production systems, but might be tolerated on a low usage home setup.
You only ever *know* that the RAID was working at the previous poll (active alerting excepted, though again technically you only *know* at the timestamp of the last event, which we hope was informational).
The assumption that it's degraded isn't knowing that it is and reacting, it's the baseline which tells you how long are you OK to be running in a degraded state before you jump on it.
If the answer is very small then you should be running with a warm spare drive (or several) available anyway.
If the answer is long enough for people to move around and do things then you don't need to check more often than that, the assumption that it is degraded is what defines your polling cycle.
Each polling cycle (or trap/event) either resets that counter or puts you into a "this drive has failed" state, which does require action on some timescale.
Basically near rectilinear means it's *really* elliptical, about as far away from a circle as you can get without the lunar surface getting in the way - it's nearly a straight line in, then out...
Halo orbit, it's actually orbiting part of the Earth Moon gravitational system, not just the moon.
It's a clever orbital position, theoretically really nice for a variety of reasons... This mission will confirm a bunch of those
"The SCOTUS will simply require Google provide that information, and thus they cannot delete it."
Maybe this is a cunning ploy for privacy - make it completely illegal to delete or refuse to hand over any and all data in an attempt to get the tech giants fighting over privacy by not collecting it all to start with.
"look at the second amendment - I don't know how you get around that one though as it's an implicit right."
It's also an amendment - i.e. it's a change to a document. You just need another one, and there is precedent for an amendment to overrule an earlier amendment.
The way to "get around" it isn't to get around it at all, but to update the constitution in line with the modern world.
"If you live in a flat with no off-street parking, you may want to buy a really cheap ICE car to get around and save money to be able to move"
Why would it have to be ICE?
There are vanishingly few places where an EV can't be at least as convenient as an ICE vehicle. And if you live in a flat with no parking then pretty much by definition you live in a highly densely populated urban area. Blocks of flats I have lived in or visited have had off street parking, it might not currently be dedicated per resident, but there has (almost?) always been off street parking.
Why would you switch to a vehicle that you had to go to the chemist to get fuel for when there are oat deliveries every day from a choice of three vendors?
EVs are the future of personal transport. I'd love e-bikes to make up a large part of that, but that's actually a completely different issue.
Public transport also needs to be properly funded, and equipped to deal with the needs of the public, rather than shareholders.
There are plenty of solutions, but burning proverbial dinosaurs doesn't need to be one of them.
"The POTS copper network should be retained as a strategic national asset. Getting rid of it to save BT a few quid is like Beeching's rail cuts."
Not sure... it's not like the majority of the network is copper anyway - even in the last mile there are plenty of aluminium cables as well.
What's the strategic national interest in copper over fibre?
Beechings cuts were disastrous because the prevented people accessing the mainline, so alternative forms of transport became necessary, and at that point easier to use that alternative for the whole journey.
Yield must be awful - I'd love to get a few A3/A2 displays - heck, if they were reasonably borderless I could patch them together with a raspi behind each one.
But they are multiple thousands of pounds each...
Digital signage is such an obvious use case, and doesn't require high refresh rates - doesn't necessarily need colour (though that could be a nice to have).
