Apparently the Blood group you have is a factor on severity
Type O and Rh-Negative Blood Type Protective Against COVID-19

I have seen endless "papers" about blood type and relationship with disease. Most of them have been pure junk.

Which is a shame because it seems entirely reasonable that there would be at least a degree of association.

But that looks better than many.

This is an interesting take on population proportions by blood group:

they call their hydrogen 'green hydrogen' though.
Still, it makes sense to capture and store the by-product CO2 from the process of making hydrogen and the location seems appropriate.

They do indeed. But those outside looking in claim otherwise!

And carbon capture, as being promoted, I find deeply questionable. Schemes like pumping down oil wells. If it leaks out, we could be worse off. Only tightly bound can it possibly work. Like a new Cretaceous period!

Here is a likely possibility

Exhibit A: https://newscientist.com/article/2274018-why-the-uk-changed-covid-19-astrazeneca-vaccine-advice-for-under-30s/… AZ effectively banned for under-30's. Note date.
Exhibit B: https://mirror.co.uk/news/uk-news/uk-running-short-pfizer-vaccine-24475534… UK running out of Pfizer.
Exhibit C: "Daily 1st doses" now <25% of March peak. UK Gov has run out of vaxx for under-30s.

THIS may explain the policy behind

Not Brexit but the thread has gone a bit OT from time to time.

Impressive claim from Volvo.

Volvo says its electric cars will have 621 mile ranges from 2030

Volvo has announced a new partnership with fellow Scandinavian firm Northvolt to develop ultra energy-dense lithium-ion battery packs to be used in its next generation models.

It is inevitable that once with the might of the world's motor industry behind it, battery technology progress would be far more rapid. In just nine years since the Nissan Leaf first hit the road, it's battery for the same physical size grew from 24kWh to 63kWh capacity.

A battery with that energy density would make an interesting fireball equivalent to a large bomb in case of an accident

But OG , that is still only 1/2 the energy of a petrol tank. .. I routinely get 1100km from a fill in my Peugeot. ,..And an electric motor is at least twice as efficient.

 

[flecc]

Nowhere near as big a fireball as a cars full petrol tank with the energy density of that fuel.

And the car tank is across the rear where it's very vulnerable, e-car batteries are underslung centrally and protected by the car's front and rear crumple zones taking the impacts.

Time to stop harping on about battery fires and admit the reality that we've been living with far more dangerous ICE cars for well over a century, which as well as being able to burn us alive also gassed vast numbers to premature deaths with their pollution levels.

I don't see lithium ion batteries as being the end game for electrical vehicles. In fact a belief that there is only one magic bullet is silly. Lighter fuel cells ,and maybe hydrogen rich fuels are more plausible ,long term.

I agree long term, but am looking at the next 30 years which will be a lithium era, if only due to the investment going into that direction.

Just look at the truck world, Renault and Volvo are forging ahead with lithium batteried e-trucks now:

"Volvo Trucks has revealed details of its three new, all-electric, truck models, which are all available for purchase. Production of the new electric trucks – FH, FM and FMX – will start in the second half of 2022, initially with tractor units. The chassis will then follow at the beginning of 2023.

The new electric trio, for which the Swedish company is now listing performance figures, joins the Volvo FL Electric and FE Electric for urban transport, which have already been in series production for Europe since 2019. Meanwhile, in North America, sales of a dedicated variant – the Volvo VNR Electric – started in December 2020.

With the sales launch of the three new, heavy-duty electric models, Volvo Trucks now has a line-up of six medium- and heavy-duty electric trucks ranging from 16 to 44 tonnes. The company is positioning the FH Electric in the regional and interregional transport segment, the FM Electric as a versatile truck for local heavy haulage and regional distribution transport, and the FMX Electric as a vehicle for cleaner and quieter construction transport."

Meanwhile no-one is interested in having hydrogen fuel cell trucks and after several years of playing with them, fuel cell buses have made almost no progress in the market.

The efficiency of using energy from a battery is better than from petrol/diesel. Especially when including regen and a lot of stop-start driving.

Just what is the advantage of an 1100km range for you (over, say, a 550km range)? If every round-trip you do is well under 550km, then all it does is reduce the number of times you visit a filling station.

There are super-long-range drivers - the classics of travelling sales people. But most of us, most of the time, would only find a fairly minor improvement in their lives from the greater range.

It doesn't seem entirely faciful that if a battery requires a very precisely balanced chemistry to work efficiently, even a modest disruption to that chemistry could reduce the fireball potential of batteries. Imagine a mechanism that squirted in a litre (maybe more?) of hydrochloric acid or sodium hydroxide (as appropriate) causing a sudden and significant change in pH. That might reduce efficiency dramatically in seconds. A bit like SCRAM in a nuclear reactor!

I have answered that a few times. My trip to France, and the times I do it would stretch the endurance of current e cars. While if I got as far as my place ,all is fine ...there is a charger in the village , but the trips and times are over very rural areas and even today French service stations close early ,..except perhaps on autoroutes ..which are not the way.

Yes - but that is special to you. Many of us look at huge ranges and think that they are both wonderful and even necessary. All too often that simply is not the case.

If I can do a round trip to Bristol, a one-way trip to London or north Wales (obviously charging for return), then I'll probably be entirely satisfied. I just want the secure feeling that I can get to Cardiff or Bristol, tootle round, and return. In reality, a half-hour top-up would not make much difference as a stop is always needed for coffee, loos, leg stretch.

I would not wish to pay more for even greater range, nor to lug around even more battery that isn't needed.

What about these. You would be hard pushed to buy a decent Golf Cart with weather protection for £1,300.

I wonder what the import duty, registration etc would add to the price and how they would fair with safety tests.. But for families who have Chelsea Tractors simply for the school run and shopping it seems a no brainer.

Shame it looks a bit like a very bad "Cut and Shut" job done on a Landrover discovery and a Suzuki Jimny.

Very good idea.. like using boron to reduce combustion in cellulose... . It is not unreasonable to suggest a glass vial of the kill chemical in each cell. Not unlike the thermal fuse link inside a transformer or motor winding.

Far too expensive! Try one of these at less than half that price:

When service stations close isn't relevant. Charge points are available 24/7/365 and most are not yet in service stations anyway, the great majority in an increasing variety of other locations.

But as Oyster says, such long distance drivers as you are the exception, not the norm. At least 70% of us are low mileage and the average annual mileage of all British drivers is 7300 miles, some 20 miles day. I'm one of that majority, I last charged on Thursday 24th June and the earliest I'll be charging again will be the end of next week, 16th July, at which time there will still be over 40% of the battery charge unused, so I could easily go another week or more.

One of the major problems with oil-based fires is that burning liquid can flow over a large area carrying fire with it. (Even heavier-than-air gaseous fuels.) Resulting in a serious spread.

you'd need a 20ft container for one of them and currently, the cost of shipping that container from China costs £5,000. Then taxes will be charged on the total of the cost of the car and its shipping.
