WoT? Experimental Elongated Airbus Wings To Fly Next Year
The title of this post, is the same as that of this article on Future Flight.
I believe that this will improve efficiency.
On The Bonnie, Bonnie Banks o’ Loch Lomon’
I couldn’t resist using the first line of one of the most famous Scottish traditional songs, as the title of this post.
But a very significant power station project, is to be undertaken in the area.
These are the opening few sentences of the Wikipedia entry for the Loch Sloy Hydro-Electric Scheme.
The Loch Sloy Hydro-Electric Scheme is a hydro-electric facility situated between Loch Sloy and Inveruglas on the west bank of Loch Lomond in Scotland. It is also within the Arrochar Alps. The site was originally suggested as the location of a huge pumped-storage scheme in 1936 by Edward MacColl, but this was rejected as being uneconomic. After the North of Scotland Hydro-Electric Board was created in 1943, it became the first of their proposed schemes.
This Google Map shows Loch Lomond and Loch Sloy.
Note.
- Loch Sloy is in the North-West corner of the map.
- Loch Lomond is on the Eastern side of the map.
- The red arrow indicates the main buildings of the LochSloy Hydro-Electric Power Station.
- Loch Sloy is eight-hundred feet above Loch Lomond.
- The total generating capacity of the power station is 152.5 MW.
The facility is operated by Scottish and Southern Energy, and is normally in standby mode, ready to generate electricity to meet sudden peaks in demand. It can reach full capacity within 5 minutes from a standing start.
This second Google Map shows the power station to a larger scale.
Note.
- Loch Sloy is to the North-West of the North-West corner of the map.
- Loch Lomond is on the Eastern side of the map.
- The red arrow indicates the main buildings of the Loch Sloy Hydro-Electric Power Station.
- The four pipes carry water from Loch Sloy to the actual power station.
- The single-track West Highland Line crosses over the four pipes at their South-Eastern end.
The design of Loch Sloy Hydro-Electric Power Station is typical of many hydro-electric stations all over the world.
This third map is an OpenRailwayMap of the area.

- Loch Sloy is on the Western side of the map.
- Loch Lomond is on the Eastern side of the map.
- The yellow track is the single-track West Highland Line between Glasgow and Mallaig via Fort William
- The blue arrow indicates Ardlui station.
The railway goes close to the power station.
A Platinum Celebration for Sloy Power Station!
The title of this section is the same as this must-read web page on the SSE web site, which dates from 2020.
Sloy Power Station Development Plans
This second must read web page on the SSE web site is entitled Sloy Power Station.
This is the sub-heading.
We’re Proposing To Convert Our Iconic 1950s Hydro Station To Pumped Storage Hydro
This is the introduction to the development.
In April 2025, we submitted a planning application to the Scottish Government to convert the iconic Sloy Power Station into a pumped storage hydro scheme.
Our proposals would bolster energy security and help provide the large-scale and flexible renewable energy back-up needed in a future UK net zero power system, helping meet the UK Government’s ambition of Clean Power by 2030.
If approved for delivery, the converted Sloy scheme would be capable of delivering up to 16GWh of long-duration electricity storage capacity.
It could provide firm, flexible renewable energy for up to 100 hours non-stop.
It appears that the upgraded power station will effectively become a 160 MW/16 GWh long duration energy store.
Currently, the UK’s largest pumped storage power station is the 1727 MW/9.1 GWh Electric Mountain in North Wales.
The updated Sloy power station will have less output, but more storage capacity, than Electric Mountain.
Should There Be A Railway Station At Loch Sloy Power Station?
Google AI gives this answer in reply to “Loch Sloy Railway Station”.
There was never a permanent public railway station called Loch Sloy, but temporary private platforms like Inveruglas railway station and Faslane Platform railway station served the area. These stops were built in 1945 by the London and North Eastern Railway (LNER) to haul materials and workers—including prisoners of war—for the construction of the Loch Sloy Hydro-Electric Scheme.
Note.
- Surely, similar reasons to those in 1945 could apply to the development of the power station. Materials and workers could be brought in by rail.
- Given, the power station’s historic significance, I believe that it could become a tourist attraction and/or education centre.It could be a stop for the Caledonian Sleeper.
I believe that as time passes, the power station’s historic significance will increase.
Are There Any Other Hydro Power Stations, That Can Be Upgraded To Pumped Storage Hydro?
Google AI can’t find anything at present.
UK Army Commissions 1.7GWh/year Solar Project At Larkhill Garrison
The title of this post, is the same as that of this article on the Solar Power Portal.
This is the sub-heading.
The installation spans 2.5 hectares and comprises more than 4,000 PV panels.
These three paragraphs give a few more details.
The project forms part of the Army’s Project Prometheus programme, which is deploying rooftop and ground-mounted solar PV systems across suitable sites on the Army estate. It was delivered by Aspire Defence Services on behalf of the Defence Infrastructure Organisation (DIO).
The Ministry of Defence is also partnered with Great British Energy to deploy solar across its sites.
The commissioning follows an expansion of solar capacity at Larkhill this year through the addition of the ground-mounted array and four rooftop PV installations.
Note.
- Larkhill has a Wikipedia entry.
- Larkhill is part of the Salisbury Plain Training Area, which also has a Wikipedia entry.
- The Salisbury Plain Training Area takes up 11 % of the County of Wiltshire and is as large as the Isle of Wight.
There certainly would appear to be plenty of space for 4,000 solar panels.
Does The Army’s Project Prometheus Programme Include Batteries?
I asked Google AI, the question in the title of this section and received this reply.
The British Army’s Project Prometheus primarily focuses on generating renewable energy through solar PV systems, though specific related net-zero initiatives on the defense estate incorporate separate energy storage components like batteries.
Project Prometheus Overview
Core focus: Deploying ground-mounted and rooftop solar photovoltaic (PV) arrays across the military estate.
Main goal: Increase green energy supply, cut carbon emissions, and reduce grid electricity dependency.
Integration with Energy Storage
Solar focus: Primary Project Prometheus installations route generated electricity directly to local military buildings or export surpluses back to the national grid.
Associated storage: While standalone solar arrays under Prometheus distribute power dynamically, separate broader sustainability and pilot schemes across the military net-zero portfolio—such as Project Taurus or thermal storage trials—run alongside it to evaluate localized battery storage capabilities.
Project Prometheus would appear to be a typical well-designed solar power programme.
Project Taurus
Project Taurus has been mentioned and Google AI gave me this overview.
Project Taurus in the UK Ministry of Defence refers to a sustainable energy initiative by the British Army to construct solar-powered carports featuring electric vehicle (EV) charging ports and battery storage, starting at Army Headquarters in Andover.
It looks to me, that Project Taurus could have applications outside the military.
Comet Ridge Lands Gladstone Gas Deal
It is obviously Highview Power’s day, as this project in Queensland, Australia gets five mentions in my Google Alert for Highview Power.
The title of this post, is the same as that of this article on Industry Queensland.
This is the sub-heading.
Mahalo gas hub developer Comet Ridge has reached a deal with Highview Power to supply the large-scale electricity project it is planning to build at the Aldoga State Development area near Gladstone.
These four paragraphs give a summary of the project.
The volume of gas targeted is 3.6 PJ/a (10 TJ/d) for a minimum of five years.
Highview’s Central Queensland Energy Storage Project is to be constructed in two phases.
Phase 1 consists of a 400MW four-hour battery energy storage system, two 200MW open-cycle gas turbines, a 370MVA synchronous condenser, and associated substations and transmission lines.
Phase 2 will be the build-out of a 200MW 12-hour liquid air energy storage system.
It looks like Highview Power’s battery is one of their larger systems and is a 200 MW/2.4 GWh version.
On Highview Power’s Projects page, this is said under a header of Australia.
Highview is developing a series of base‑load renewable energy power stations in Australia, with planning now underway for three major programmes. In Gladstone, Central Queensland, and Townsville, North Queensland, we are progressing large scale projects combining LDES and short-term battery storage. On the Darwin–Katherine network in the Northern Territory, plans are advancing for an integrated scheme incorporating solar generation, LDES and battery. Together, these initial developments will help Australia meet its target of halving carbon emissions by 2030 and achieving net zero by 2050.
Gladstone is named in this story and on Highview Power’s web site.
Could Highview Power be making a breakthrough in process engineering after Sumitomo’s success at the LNG Terminal at Hiroshima.
Loganair Agrees To Buy Five Beta Technologies’ Alia CTOL (CX300) Electric Aircraft For Use Across Scotland
The title of this post, is the same as that of this article on the John O’Groat Journal.
These two paragraphs add some detail.
A “truly historic moment” in regional air travel could soon see electric aircraft transporting passengers between between Highlands and Islands airports.
Loganair announced a deal to buy five all-electric aircraft, with options for five more, on Monday.
The first aircraft is expected to be in service in 2029.
As an engineer and a former private pilot, I felt this would happen at some time, but not as early as this.
Read the Wikipedia entry for the plane to find out more about this fascinating aircraft.
The Ghostly Drone That Spins Almost Too Fast To See
The title of this post, is the same as this article on The Times.
This is the sub-heading.
The ‘Phantom Twist’ prototype rotates about 25 times a second while its body moves in the opposite direction — appearing as a faint haze
These two initial paragraphs add some more details.
Engineers have created a drone that almost vanishes in flight by spinning so quickly the human eye sees only a faint, translucent haze.
The body of the drone, called the Phantom Twist, rotates about 25 times a second, while its propeller spins in the opposite direction. Its inventors describe it as “morphing into a ghostly smudge that seamlessly blends into the background”.
This technology obviously works and was developed at North Western University in the United States.
This paragraph speculates on a few civilian uses.
It is, they say, intended for civilian uses. The researchers believe less conspicuous aircraft could be useful for monitoring nesting birds, surveying wilderness areas or inspecting bridges and other infrastructure without causing wildlife to scatter or prompting people to alter their behaviour.
The article then details how drones have transformed the war in Ukraine.
An Avenue Of Trees, Cheered Me Up Today
I was feeling a bit down, after the loss of my phone on a train yesterday, as I cam back from Cambridge South station.
After reporting its loss at Liverpool Street station this morning, I thought I might be able to get something I needed at Sainsbury’s in Walthamstow.
To get from Walthamstow Central station to Sainsbury’s I walked along this avenue of trees.
Note.
- It was lovely and cool on a hot day.
- There was a gentle breeze through the trees.
- Halfway along, I chatted to a guy with Indian heritage. He said he liked the trees at Chistmas, when the Council put lights on them.Now surely, that is multiculturalism.
I asked Google AI about the trees and got this reply.
The avenue of mature trees leading from Walthamstow Central Station towards the High Street consists of lime trees. Also locally referred to as Lime Tree Walk, these established trees are well known for soaking up pollution from the adjoining bus and transit areas.
Google AI estimates that the trees are at least a hundred years old.
I believe we should do things like this more often, as it is surely a scientifically-correct way to deal with the pollution of only a few vehicles emitting it.
Out of curiosity, I asked Google AI,”Are we doing research to increase the effectiveness of trees clearing pollution?” and received this reply.
Yes, there is extensive, ongoing scientific research dedicated to increasing the effectiveness of trees at clearing pollution. Studies focus on optimizing urban canopy cover, vegetative barrier design, and microbiome/soil enhancements to maximize both particulate matter (PM) capture and carbon sequestration.
Current research initiatives and findings include:
Vegetative Barriers & Species Traits: Research from the University of Surrey’s Global Centre for Clean Air Research (GCARE) has developed a plant selection framework. By evaluating traits like leaf hairs, canopy density, and seasonal leaf retention, they identify highly effective species (such as silver birch, elder, and yew) to act as physical green barriers that trap particulate matter and filter exhaust.
Tree Spacing & Dispersion: Studies on urban street canyons show that sparse or dense tree spacing can sometimes trap pollutants if the canopy blocks wind flow. However, “medium spacing” (where the gap between trees is roughly equal to the crown diameter) has been proven to optimize both airflow and particle reduction for pedestrians and cyclists.
Soil & Growth Interventions: Studies like the Glandwr Forest Carbon Study by Imperial College London and The Carbon Community are testing methods to boost young tree growth and carbon sequestration using enhanced rock weathering and microbial enrichment.
Cooling & Air Purification Pathways: Recent findings published in Landscape and Urban Planning highlight that trees reduce particulate pollution (PM10) not just by trapping it on leaves, but also through localized cooling. By mitigating extreme heat, trees promote the natural deposition of suspended particles.
It seems that the good citizens of Walthamstow and the nearby forest, probably achieved a result, that was very much in line with modern research.
Does BYD Stand For Bet On Your Destination?
Today I came back from Walthamstow Sainsbury’s to my home in Hackney, using two BYD electric buses on route W15, a diesel bus on route 488 and a Reliable Routemaster on Route 38.
Both the BYD electric buses stopped short of their final destination.
I also changed early to the 38, so I could have a Diet-Coke in a cafe that looked friendly.
It was!
- As you can see, it was right by a bus stop, where luckily for me, 38 buses called.
- I have written a few posts about the horrid BYD electric buses on route 141, but London shouldn’t be made to suffer an inferior product.
- If Manchester and Leeds can have UK-built buses by Wrightbus, that are delivered as diesel and converted at an appropriate time to zero-carbon, why can’t London and the rest of the country?
London’s fleet of a thousand Routemasters, which were built by Wrightbus, a few years ago, seem to have found a new niche in the world of advertising and I wouldn’t be surprised to see an experimental fleet of zero-carbon Routemasters.
Here’s a few images of Routemaster paint schemes.
I like them. I wonder, if a bus has gone missing to have a special makeover, if England get to the latter stages of the World Cup?
Olympia Exhibition Centre – 18th June 2026
I went back to Olympia today and took these pictures.
I don’t think, I’ll be going again, as they don’t seem to have any gluten-free food.
Clapham Junction Station – Platform 0 – 18th June 2026
As I passed through Clapham Junction station, I took these pictures of Platform 0.
Note.
- Platform 0 has the red brackets along the back.
- Platform 1 has the Class 378 train for Stratford parked in it.
- There is a useful Costa Coffee, with a waiting room behind it on the platform.
Little seems to have changed since I wrote Barriers And Planters On The London Overground Platforms At Clapham Junction Station, except that the barriers and planters have been removed.
A Simple Way The Overground Could Operate
Surely, if Stratford trains used Platform 1 as they do now and Dalston Junction trains used the new Platform 0 would enable a much faster interchange between the two halves of the South London Line.
This OpenRailwayMap shows some platforms at Clapham Junction station.
Note.
- The orange tracks are generally tracks in platforms.
- The blue dots are platform numbers.
- The top orange line in Platform 1.
- The dotted line will be Platform 0.
I suspect that with a few extra junctions, the two halves of the South London Line could access the opposide sides of the island platform 0 and 1.
It would certainly speed up passengers on their way between East London and the Olympia Exhibition Centre.
