Oman appears to be keeping quiet about this so as to not antagonise the US but importantly they are not denying the news which has been appearing in regional news sources. Interestingly the Oman based press is also keeping quiet.
We just need a certain person to keep his mouth shut in acquiescence to the deal and quietly let the dust settle. Unfortunately I'm not optimistic.

Operating in the opposite direction heat pumps in Northern Europe can manage over 40C temperature gradients with a decent efficiency.
Key to good efficiency is insulation, building sealing and ventilation heat exchangers. Humidity management also plays an important role.
I would avoid any company which puts uninformed crap like that on their website.

I fundamentally disagree with the blog post. Aircon units can an frequently do maintain a far higher indoor/outdoor differential than 20F (11C). It all comes down to proper system engineering and building design. The writers really don't understand what they are writing about.
I'm currently in Oman which frequently reaches around 50C but buildings easily maintain 23C which is almost a 50F difference between inside and out and the buildings have very poor insulation.

The approach of sentencing on the basis of crimes not explicitly put before the jury is in my opinion profoundly wrong and is contrary to what I regard as natural justice. I'm absolutely fuming.
https://www.theguardian.com/uk-news/2026/jun/12/palestine-action-activists-sentenced-terrorists-damage-elbit-systems-uk-israel
Whilst they are sentencing non-violent convictions as terrorism maybe they should charge anyone working for EBIT directly or indirectly as aiding and abetting the commission of genocide. I'm sure we can find some space in the prisons for them.

Anyone remember the old Mutt email client?
I had to use it again this evening to successfully find a 10 year old email from a bank buried in a 4GB MBox file in my archive. Quick grep to find the correct file then Mutt to view the message..
I've not used Mutt for about 15 years but the keystrokes came back to me almost immediately along with memories of SSH sessions to remote mail servers 25 years ago.
Happy days.

If this goes badly for the defendants I see an eventual direct appeal to the European Court of Human Rights in Strasbourg.
UK courts are supposed to take into account the ECtHR treaty obligations but I don't see any fairness in the way these proceedings are being stacked against them.

For some reason I cannot explain I decided to make some bread. No mixer so had to do everything by hand.
First time I've made bread by hand for over 40 years, I had a bread maker about 10 years ago which magically produced bread which you had to dig the aluminum paddle out of the bottom.
Final result is better than I had any reason to expect. I haven't tasted it yet!

Why did Trump want to send a hospital ship to Greenland?
You really can't make this up:
Jørgen Boassen a MAGA loving Greenlander (apparently there is at least one) was staying with Governor Jeff Landry for Mardi Gras and told him that his mother has been misdiagnosed and died of sepsis and that the health service sucked. Jeff Landry then told trump about all this and it turned into sending aid in the form of a hospital ship!

It is my opinion that much of the price rise can be traced to Maggie Thatcher and her cronies forcing local councils to sell off their housing stock and not permitting them to build replacements. This combined with powerful lobbies of people owning houses who wanted to see the prices go up all the time by limiting construction through planning laws ended up squeezing anyone who wants to get onto the housing ladder.

We could put everything into public ownership but it wouldn't fix the issue of not enough homes. It is no different to other essential things like food production - you pay someone to provide that and expect them to make a little extra to make it worthwhile - maybe they shouldn't own farms!

Landlords are not the cause of high prices but they are an easy target to point a finger at.
By your argument mortgage companies and anyone who lends for profit are obscene too along with those financing them via private pension contributions.

On the other hand, could the current tenants afford a mortgage for the same properties over a 20-30 year period?
The solution is to remove scarcity by building so prices come down to something related to the cost of construction so people can afford to buy them or rent at a similar price should they chose to.

you are missing the point, most long term unoccupied properties were primary homes which cannot by used until probate is complete. If you speeded up this process I would expect a lot of them to transition to sale for homes or to rent.
I've properties which have been in use at a fair rent almost continually for 10 years.
As I said - if there was sufficient supply/housebuilding none of this would matter because prices would come down and availability up.

2025-08-29 13:08:32 GMT

- reply

One factor not often discussed is how long the probate process takes in the UK. Six months to a year is not uncommon during which time the property cannot be sold or used for other purposes. This accounts for a large proportion of unoccupied properties.
Properties deliberately unoccupied appear from my limited research to be high value (£1M++) where any rent would be insignificant compared to the property and would be too high for homeless people anyway.

Don't know where you got that figure from. According to Crisis long term unoccupied is 265K for various reasons. Due to the nature of this organisation they are unlikely to understate the actual number.
In any cases in some places there are local measures to bring unoccupied properties into use like double rates on second homes in Shropshire.

withholding of properties is a form of supply constraint and would only work if the owner had control of a significant proportion of the properties as losses would greatly exceed any potential gains. It is a nice theory but fails when you analyse the probable outcomes.
In any case if there was a large pool of property then nobody would be able to control availability because others would simply undercut them. Simple market economics.

2025-08-29 11:57:29 GMT

I think you are confusing symptoms with causes. Like most things there is scope for both ownership and renting /leasing.
There are good reasons for people choosing to rent or buy - it all depends on circumstances.
The underlying issue is the limited availability of properties due to supply constraints and lack of council housing. This results in high prices and unaffordable rents.
I'm happy to agree to disagree. The world is big enough for both viewpoints

2025-08-29 07:23:55 GMT

It is another attack on private landlords which will almost certainly not apply to companies.
Just like where companies can offset mortgage interest payments against income but individuals renting out properties can't.
Just means an increasing number of rental properties will be run by faceless corporations who pay money to political parties.
By the way, I'm not rich. I just put my savings into property rather than a pension because I lived out of the UK for many years.

Remounted and enlarged my solar array in Cottenham this week. The older wood frames really suffered in the winter storms so I ended up putting concrete posts in the ground bolting through them to heavy timbers and mounting the panels on unistrut. Panels optimised for winter.
Hopefully this will give me a long life.

The company must be fairly confident they can find it as an 18 month contract for an exploration ship is a big risk (no find no fee).

That bridge in Siberia makes me shudder just looking at the photo so I went digging on Google about it.
Apparently it was originally a railway bridge but was no longer up to the job so they built another nearby. This one was then essentially abandoned and is gradually degrading with essentially no maintenance. It is liable to collapse at any time.
Another thing to add to the list of cool things I never knew about.

Denmark has already been making noises about controlling shipping passing through its waters - checking valid insurance etc.
If these incidents continue I could see them banning Russia bound shipping from their waters. This would cause a major diplomatic incident and long arguments about international seaways but there isn't much Russia could do apart from banning others from their waters which would only hurt themselves.

Yesterday another set of cables were broken in the Baltic by a ship leaving Russian ports. One 650MW power cable and another 4 comms cables.
For "some reason" the ship slowed just before it went over the cables and when it was later boarded the anchor was missing.
The ship is called Eagle S, is registered in the Cook Islands and is owned by a UAE freezone company Caravella LLCFZ. Good luck finding the actual owners.

Just had 3 solar panels come off the ground mounts in the strong winds and rain. Looks like a mounting fastener broke and the failure spread to the adjacent panels. One of the U fixing brackets has lost both sides where they hold the panels!
It is absolutely horrendous outside at the moment. I secured the loose panels and will assess the damage in the morning when I can see more than a couple of feet in front of me.
Here is hoping the remaining 30 panels are OK.

nuclear is not dispatchable but baseload. You can't switch it on and off quickly. Until batteries came onto the grid the fastest switching was hydro taking a minute or so followed by open cycle gas peakers which take a couple of hours.
The most dispatchable power now are batteries & solar & (slower) wind. They can almost instantly change state but I assume this does not fit into your pro-nuclear agenda

I often hear people saying how good UK plugs are. They are OK but have their problems at high currents as the internal fuse gets hot and can melt the insulation and connections.
This example is 9 months old and was used a couple of days a week for car charging - load was about 12A.
The Bussmann fuse in this good quality plug cooked everything and ended up welding the plug into the socket with the heat.
