Maybe a sticking over-run valve in an SU butterfly ?

IIRC RR-Vickers have a contract to design small PWR reactors based upon their nuclear sub installations.

The spike-targeted vaccines do act to reduce severity of an infection, but do little to reduce virus amplification and transmission. Yet govts are acting as if vaccination prevents omicron spreading. But they do not. The virus uses molecular weaponry from its capsid proteins (N, and two Orf) to block innate, "type 1 interferon response" retaliation by all the cells lining airways. These defences are tuned up by D3 and lie in wait to disable any microbe or virus variant- PROVIDING D3 levels are high enough. But only a tiny percent of global humanity has good D3 status and so the virus proliferates out of control. And with that will come new variants, inevitably. So D3 is not just another therapy: our D3 deficiency is the door we have left open for the virus to exploit.

Yours is rather more subtle Peter, I like it!
Tks Nick and Colin,
I'm past fettling it so hoping grandson#2 passes his test and is keen to get out get under as well as pose. Would be good to get water injection working: about 10 extra RON !! Peter

Whatever its failings and inertia marketing ploys, Amazon has allowed us to shield from C19 with little hassle. But I dread to think of the carbon footprint of the vans delivering to us way out in the sticks.

Let's hope the booster jab does work against omigod. Because most of the population of South Africa have much better 25(OH)D than UK. Almost all exceed 50 nmol/L whereas more than half UK are below. So evidence form SA that it might be less severe C-19 has to be treated as not applicable to UK.

1 million views already - the D3 mssg is spreading. Israel GP describe his approach to prophylactic use of D3 against C-19.

Can local garages with no e-car expertise whatsoever do MoTs on PHEVs ? or is it a Main Agent task? And servicing the ic engine, is it also a specialist task?

Very good discussion about Hybrid and BEV cars. This was from an IET meeting.
Like most technology changes the devil is in the detail, not something the politicians are very good at.
Interesting conclusion, BEV are not the best solution to reducing CO2 at the present
Mike, riveting analysis, very informative indeed. I had not realised that modern hybrids are not like the Prius or Volt where the ic engine runs only at optimum thermal effic (ie rpm for peak torque, load ca 2/3rds max). He mentioned that at 59mins, but didd not elaborate on the further reduction in CO2. Also if a PHEV is used only on battery what is the impact on the ic engine remaining unused for maybe months on end ? For classic owners he attributes CO2 for manufacture 50 g per km approx, a figure worth noting when the neighbours complain about the Triumph's tailpipe emissions.

It grows on water-logged river banks so for lots to appear on the sea-shore suggests a river has scoured away its bank somewhere. There's an acre of it near us -sheep wont even nibble it, the whole plant is toxic. But impressively fast-growing !

Hi John, The power of fast-flowing water is terrifying. Our house is at the bottom of a 300ft hillside right next - 15 feet away- to a stream that drains ca 20 acres of pasture above us. In a deluge it can change in 20 min from a trickle to a brown, rock-entrained torrent. I am at present building a low wall 50 feet above the house to raise the leeway where the stream is likely to breach. Locals tell me that years ago the stream broke its sandy bank at that point,the flood entering through the rear stone wall and exiting through the front door. I watch the rain forecasts with apprehension...

What;s the solution ? Post-hoc charging at punative rates for unjustified 999s ? use proceeds to buy and staff more ambulances.

It's enough to send me dotty. My guess is the brain makes up a dot in the blind spot and forgets to remove it when we move our gaze.

We have been lucky, have been with NFU for 20 years and they never pulled a stunt like that.

Heat pipes are evacuated so the small amount of water they contain boils to vapour easily, and only afew degrees temparature difference are needed to transfer heat from the warm to cold end. Thermosiphon types simple allow the condennsed water to flow under gravirty to the warm end.

I'm pretty sure the state change heat-transfer is symmetrical or whatever you call it - the condensing gives out as much energy as the evaporating takes in.
They heated up a 23 m^3 tank of water (heavily insulated ) in summer using vacuum tube solar water heaters, up to ca 70C. Then drew heat off in winter with a water-to-water heat pump. My thought is to build a passiv house ontop of the water tank , heat it up in summer with surplus solar energy from pv array, and thn retrieve heat in winter using thermosiphon heat pipes extending up from the water tank to the rooms. No electickery apart form solar pv and immersion heaters in the tank, and no elec supply needed to keep warm in winter. Havent started on the sums yet, but a floor area of ca 120m^2, and a tank depth of say 2 m, gives a water storage volume of 240 m^3....and with enough spare solar pv to heat it upby end-summer that should supply enough heat to last a well-insulated dwelling all winter. Even if the grid fails.

Tks Egret, it looks like seasonal heat storage is feasible on a large scale, but not much done (yet) on domestic single properties
https://en.wikipedia.org/wiki/Seasonal_thermal_energy_storage
The Irish experiment looks interesting, but did it work ? ! Personally Im not a fan of complexity so bleeding hot air from a thermal store to provide space heating is attractive, if it can be done. There's a shortage of plumbers around here, so water pumps etc are not attractive, let alone heat pumps.

Has anyone come across the use of thermal heat storage in combination with ASHP ? We have space for lots of solar PV but need very little, jsut water heating and domestic appliances in summer. It strcuk me that the summer excess could be used to heat a large thermal store to act as a source for an integral ASHP through winter. Maybe sealed shipping container(s), super-insulated and stacked with rocks....... Anyone know of such, where real-life numbers are given ?

Coal for domestic fires is banned in a couple of years, only engineered smokeless allowed after that. As the elec supply often fails around here, and we a re low priority, a solid fuel fire is useful emergency back-up. I'd best ring-bark a few trees, to ensure a supply of dried wood. Out here there is no gas, we rely upon oil for heating and hot water. If ( when) burning oil is banned, solar panels will get us through summer, but not in winter. Insulation, engineered coal and logs seems to be the only practical answer for winter heat whenever the electrical power fails.
Putting all our eggs in one electrical basket is risky. As demand outstrips supply rationing may be the only poltically acceptable solution, millions are in fuel poverty already, and they cannot be left to freeze. Nor can they afford to install - and repair - heat pumps.A big concern is reliance upon wind in a winter "blocking high" where there is no wind for days. In the absence of CEGB planning, the profit imperative means that gas-powered plant that might be used to take up the slack in such a infrequent weather event will no longer be available.

Yes, another piece of evidence - the paper is here:

I'm not surprised. The alpha variant evolved a mutation is a non-spike region that allowed it to weaken our innate immunity. Good D3 is needed for good innate defences.
