General Discussion Area / Re: Parliament to be suspended
« on: 29 August 2019, 20:01:06 »
Another important part of our constitution is the presidents & procedures on how Parliament works. I recently bought myself a slightly out of date 2nd hand book on this as the latest versions are expensive.

As mentioned earlier our unwritten constitution can updated by simple Commons majorities, this is a blessing as it allows sensible changes to be made and also a potential danger & possible curse if you've got a parliament, say lead by a terrorist loving Marxist, that by a simple majority can abolishing our democracy & turn us into a one party state. :(

What has become clear with Brexit is where our parliament has been so enfeebled & undermined here & likewise in all EU states that most of the current crop of MPs are quite incapable of anything beyond virtual signaling, gesture, identity politics so most can't run the country or make decisions which means they can't do the job they are elected for or earn their salaries and 'creative' monthly expenses.

Once parliament were progued for the summer break Dominic Cummings pointed out that it was now too late to stop Brexit. If Boris lost a vote of no confidence (by no means certain) he then has 14 days to either resign or to try & get a majority vote to continue or call a general election. Realistically, the earliest this vote could be held is early November once we have left the EU on WTO terms. The only way remain MPs can now stop Brexit is by revoking Article 50 which would finish the careers of most of the politicians who went down that route. What has changed in the polls since Boris became PM is the Conservative polling, where they are the lead party again with 30%+ & the collapse of Labour where they are hovering around 20%. I suspect what will really hit Labour hard will be the Northern vote, who will never vote Tory because of the miners strike but will the Brexit party where they were the most dominate Leave areas in the UK.

Although parliament is sovereign the whole strength of democracy is that we get to hire & fire them every 5 years through the ballot box & this has a considerable moderating effect on what governments & MPs do where they want to be reelected again. Major's ERM fiasco, Maastricht Treaty shenanigans & general incompetence lead to their 1997 ballot box hammering & to 13 years & an incompetent PM with Gordon 'no more boom or bust' McRuin before the Tories got a sniff of power in 2010 with a minority government & coalition.

I suspect the next few weeks are going to be interesting but master strategist Dominic Commings & Boris have certainly taken the initiative, made the right strategic calls so far & put remain MPs of their back foot & if they keep doing this I think the odds will be on Boris' side in getting this over the line.

One this is certain is that UK politics will never be the same again & I live in hope that this if for the better.

Where it has been mentioned the our parliament is sovereign this is not strictly true until we leave the EU as EU law & ECJ rulings currently take precedence over UK law until we leave & have repealed the 1986 Single European Act.

I'm not sure how true this is, but I read that the crew of the yacht that Greta Thunberg (the 16 year old climate change expert) is sailing to New York on will be flown back to Europe and a replacement crew flown out to bring the yacht back.  :)

Spot on it is all about virtual, identity signaling for the easy lead sheeple. :-X

Taxpayer money tree, so why spare any expense?

[digression]
Glacial speed is another reason when the government & railways are involved, the West Heathrow loop was proposed in 2012 connecting Reading & Slough to Terminal 5 with a 3.4mile link which would be operational by 2020, this has slipped to 2024, if we are lucky!

https://en.wikipedia.org/wiki/Western_Rail_Approach_to_Heathrow

Don't ask if & when the Heathrow Southern Railway link will be built where it was proposed in 2017 with a tentative operational date of 2025-27 for it's mighty 8 miles of new track.

https://en.wikipedia.org/wiki/Heathrow_Southern_Railway

I fully support both of these privately financed lines that IMO should have been build years a go, where trying to get to Heathrow as our premier UK airport from the West/South West using public transport has always been a joke & at long last we will have decent connections.
[/digression]

So with HS2 you have all this money wasting jobs for Civil Servants, who can put in on average 10 minutes in the morning between first & seconds tea breaks & then after a leisurely 1-2 hour lunch they can do another 10 minutes between tea breaks three & four, before leaving on the dot from all this exhausting hard work. :D :D :D

Another major escalation on costs is climate fraud where it need to be 'carbon neutral' & lined with thousands of noisy bird slaughterers so at the bottom of the next carbon cycle we drop below 120ppm & all C3 plants and almost all animal life dies, swell. Hard-left tree huggers are happy to destroy life on earth to get rid of their hated capitalist Western civilization & most animal life as collateral damage is acceptable. They have never forgiven us for defeating their Marxist ideology in 1991 with the fall of the Soviet Union & China seeing their only survival path for their Communism was by bolting capitalism on to the side of it. Climate fraud where I have been digging on the history of this was started in the 1990's but a group of UN Canadian environmentalists where the West is based on abundant, cheap, reliable, energy. A clever new front by the hard-left to prove they had lost a Marxist battle but by no means lost their subversive war.

The rich play holier-than-though by offsetting their carbon footprint while the many plebs pick up the real costs like HS2 cost escalation, expensive, rare, unreliable energy & the steady deindustrialization of the West where India & China are happy with their 550 coal fired power stations under construction to become the industrial powerhouses of the 21st century as we descend to 3rd world status industrially & culturally.

Spending on bad 'white elephant' projects that will never come near to paying for themselves, just weakens a country & it should IMO be scrapped.

Maybe Denmark has already agreed a sale with Russia or China!  ???

Rods?  ;D

Not sure if the sale of the US to Russia at a bargain price by Trump will happen before or after 2020 election as it looks like Trump being King of Greenland is now off the menu. ::) ::) ::) ;D ;D ;D

Whenever Putin is on this travels for international conferences etc & the country he is visiting customs control & go through the standard questions: When they ask occupation? He retorts, it's okay I'm only visiting this time! ;D

General Discussion Area / Re: Fighter Pilot : The Real Top Gun
« on: 23 August 2019, 00:45:53 »
What is more important if you have to 'mix it' with an enemy interceptor is thrust to weight ratio, turn & climb rates & especially thrust to drag when maneuvering as this will bleed off speed in a dogfight and these normally occur at subsonic speeds. What you don't want to do is run out of energy by being low & slow, so you can be picked off. Top speed is only a major issue when you have to 'bug out' & then once beyond visual range stealth will play a very important part in the F35.

None of the current generation of fighters expect to get into a dog fight. Not saying it can't happen, but the idea is that you engage the target at well beyond visual range, and the first the target knows about your presence is when your missile goes up their tail pipe. F-35B doesn't even have a gun and the RAF Typhoons have the gun port blanked off (it was too expensive to remove the gun itself because it upsets the balance of the aircraft). Modern short range missiles have high offset bore capability, and both the Aim9X (latest gen sidewinder) and the ASRAAM can be targeted at an aircraft behind the launch plane.

The F-35B isn't intended to be a 'fighter' - its a 'bomber'. In stealth mode it can only carry 2 ASRAAM's, plus 2 1000lb bombs internally. Longer range AIM120 AMRAAM's have to be carried on wing mounted pylons, which means the aircrafts radar signature increases massively - it's no longer stealth. AIM120's don't fit in the F-35B's weapons bay, and the funding to make them fit has been cut. The ASRAAM's are only there to engage targets of opportunity - basically things that get in the way. F35B would rather evade/run away from a threat than try to engage it. In the past both Tornado GR1/4 and Nimrod have carried sidewinders, but neither had any pretences at being an air to air fighter.

Agree with all of this & with the increasing use of standoff weapons, there is less need for penetration into enemy held territory.

Super cruise massively increases an aircraft's supersonic range as when you have to use the afterburner to go supersonic you get through fuel so fast you can only use it for minutes on a normal mission profile.

Pilot overload can be an issue in a single seat combat aircraft & the F35 sensors & systems are second to none in terms of pilot situation awareness & minimising workload which will allow it to win in many situations.

As an aside where there is a big car market for steal to order & break for spares, especially with them ending up in the poorer parts of Europe & Africa. How long before EVs are stolen to order for their batteries?

Agreed. I always expected one option for motorists would be to call at a service station and pay for a standard replacement cassette battery that is charged up on an exchange basis so you could do long journeys. Service stations could be equipped with solar panel arrays and a wind turbine.



That's not really practical, you need a large number of cells to make a battery big enough to power a car so replacing them like you pump fuel into a tank is unlikely to work. Then there's the value of the things, they're a large part of the value of the car and just swapping them is going to cause all sorts of blame when something does go wrong.


And not necessary really. 150kw CCS chargers are being rolled out now. Add that to a 200 mile EV and it means you drive for 3-3.5hrs (mostly it's tough to average 65mph over any journey) you then stop for 15-20mins and you can get going again. This is the reality of the Tesla model 3,S and X and it's superchargers which are already 125-140kw with 250kw units on the way. This tech will trickle out into other manufacturers soon enough (iirc the Porsche Taycan will allegedly take 350kw).

Of course, if the physics and chemistry is truly settled and as simple as faster charge = battery death, I assume pushing 350kw into a battery will kill it in a matter of months....

The 8yr, 100k mile, 70% capacity warranty will surely take a battering...

That is an area where big improvements are being made & real world use instead of theoretical development testing cycles will give an idea or what ideal v real lifetimes are. One thing with fast charging is the voltage & hence current increase & charging efficiency goes down where more heat is generated & this will stress the batteries more. Again real v actual will only be known over time, but if you can charge the batteries most of the time while they are still over 50% and use slow charging most of the time then you can expect the batteries to last much longer. If you are on a 3yr contract as long as they last this duration, do you care if they don't for an owner down the line? I'm not sure it would overly bother me where I've paid a new car premium for the convenience & reliability while I owned it & if somebody buys secondhand then that is there problem. ;) How long before there is a Terry thread on: How do I replace the batteries in my 200k mile very cheap ev? ::)

TB is right & this advice is exactly the same for all lithium battery based devices including mobile phones. There are three types of batteries unprotected two terminal ones, which have a real risk of fire & explosion & two or three terminal protected ones where two terminal are internally regulated & externally regulated ones use the third terminal to get the charger to regulate it, which is used to control the charging rate and temperature.to stop them bursting into flames & destroying themselves & their surroundings. Once a cell is out of the safe specification, the regulation system will stop that cell from being charged to stop any fire & explosion risk. Lithium battery capacity is affected by temperature & like all batteries there will be ~1% per day self-discharge rate. Apparently hydrogen powered vehicles have a much higher natural fuel evaporation rate compared to fossil fueled cars where the atoms are much smaller & more difficult to contain.

About 25% of an EV car's battery pack is each cell's electronics to keep them safe. Like in all areas better lighter electronic protection/regulation systems are happening with many new patents in this area so I expect the 25% weight to drop as better designs are introduced, but batteries are always going to be at a big disadvantage where there energy density is much, much lower than fossil fuels & that is unlikely to ever change by much, where there have only been incremental improvements over the last 100 years of battery development.

In between developing an unenclosed nuclear powered cruise missile that has just blown up killing 7 and giving Eastern Europe a measurable radiation cloud, maybe next week Putin will decide that unenclosed nuclear cars for the masses is the future, what could possibly go wrong. :o :o :o Such small nuclear reactors have to be unenclosed to make the weight viable if you are putting them in missiles. The US worked on this in the 1960s before deciding it wasn't a good idea.

I have recently had this problem on a USB charged lithium battery torch where the discharge rapidly went from reasonable capacity to about 10% capacity in about 10 charge cycles until it wouldn't charge charge at all. A lesson I've now learn't is when you buy a rechargeable lithium LED torch make sure the battery is replacable. :-[ :-[ :-[ Me being me after several attempts at taking it apart I decided that there must be a battery compartment threaded access on the cylindrical aluminium body & the use of two pairs of stilsons on it, I found the locktighted joint. It contains a bespoke 3 terminal design AA sized battery & where I  haven't been able to find a replacement I've disconnected the internal USB charger & will charge the internally protected replacement using an external charger on it. :y There are also several times of positive terminal with button head & flat head being the most common.

It's not really about the fuse in the incomer, though. A 70's delivery network was probably designed with an overnight diversity of between 1 and 2 kw per house, and the fact they were fitting 60A fuses might indicate that it has got worse than that since. That'll all be absolutely fine when everyone's got a milk float on charge overnight, of course. ;D

Electrics aren't my strong suit, I can wire a plug, know how to run cables to keep building control happy, but diversity loses me a bit.

Kevin, can you explain why you would have night time diversity that's different from peak, say when everyone turns on their oven, shower or kettle, which 80% of people do at the same time.  ???

Even if I get a 7kw wall box put in, that's still pulling less than when I have a shower, (9kw) or more to the point at 645am when loads of people put the shower on.

Essentially, they size the network and the substation that feeds it based on an assumption of what the average consumption of a house will be at various times of the day, knowing that it will be many times higher for relatively short periods of time during the day. Not everybody takes a shower at the same time, so a 9kw draw for a few minutes at a time doesn't cause a problem where there are other houses drawing very little energy. Over a development of a few hundred houses it all averages out to a reasonable current draw from the substation so everything can be rated for very little current in comparison to the maximum that each household could consume multiplied by the number of households. This reduction from the theoretical maximum current rating required (which is impractical) is called diversity.

The network can withstand short periods of substantial overload such as when sunday roasts are in the oven or when a popular TV programme ends and everyone puts the kettle on. This is fine as long as the network gets some time to recover, which is where the likely night time loading comes in. For a housing estate with gas central heating fitted, this can be very low. A few hours of light loading allows substations and underground cables to cool off (they are large items with considerable thermal inertia). The sizing of the infrastructure relies on this period and so a big change to the pattern of night time consumption across many homes would invalidate the diversity calculations and cause the local network to need to be resized if it is to remain reliable. A switch to charging electric cars at night is exactly the sort of change that would cause this.

Where I live the underground cable joints are gradually failing leading to a prolonged power cut if your on the same phase as the faulty joint, where they have to dig up the road & replace it. Much higher peak loadings & bigger temperature cycles aren't going to improve this reliability. :(

But that's when solar renewables are at their most efficient.  Oh, hang on a sec, they haven't thought that one through too well...

At least the windmills will make up for that for night charging, where wind is solar driven there is generally less of it at night & during the winter when you get peak demand, especially when we have an exceptionally cold high pressure area over the UK for a few weeks. Last winter over a 6 week period they were only generating at an average of 13% of peak capacity with their bird slaughterers. Doh. :o :o Will the phrase "In the Doldrums" apply to electric cars when your becalmed from not being able to charge it for a few weeks? ::) ::) ::)
