Is The Varsity Line Trackbed Between Bedford And Sandy Still There?
I asked Google AI, the question in the title of this post, and received this answer.
The trackbed between Bedford and Sandy largely survives as an open, walkable alignment, but the original tracks themselves were removed decades ago.
Today, much of this section of the old Varsity Line (often referred to as the Bedford-Cambridge route) operates as National Cycle Route 51, though a few specific areas have seen modern development.
The status of the trackbed varies depending on the specific location:
:Bedford to Sandy (General): The rails and sleepers are long gone, but the formation is still clearly visible.
A large section of the trackbed between Bedford and Sandy has been repurposed as a traffic-free path for cyclists and walkers (National Cycle Route 51).
Sandy Station Area: The former Varsity Line platforms at Sandy were cleared after the line closed in 1968.
New housing has been built over parts of the route through the town, altering the original alignment.Because the original alignment was interrupted by modern housing and other developments in certain areas, the upcoming East West Rail project—which aims to re-establish a direct railway between Oxford and Cambridge—will bypass the original trackbed for the central section (Bedford to Cambridge).
The new railway is slated to follow a slightly different route.
Conclusion
The March Of The Batteries
One of my Google alerts picked up this story from the Solar Power Portal, which is entitled Gresham House To Acquire 480MW BESS, Completes Financing On 397MW Portfolio.
This is the sub-heading.
Gresham House Energy Storage Fund signed a Sale and Purchase agreement (SPA) for the conditional acquisition of a 480MW BESS project, while also completing funding on a 397MW portfolio that will begin construction.
I asked Google AI, “How Big Is Gresham Houuse’s Portfolio Of Batteries?” an received this answer.
Gresham House Energy Storage Fund (GRID) operates a portfolio exceeding 1GW of utility-scale battery capacity in the UK, with an active pipeline of future and recently financed projects.
Their operational capacity features:
Operational Capacity: Exceeds 1GW (approx. 1,072MW/1,701MWh) across dozens of sites.
Market Share: Owns roughly 17% to 20% of all utility-scale batteries in Great Britain.
Haven’t they done well!
When Will Highview Power Complete The Carrington Battery?
Highview Power is building a 50 MW/300 MWh liquid air battery at Carrington, near Manchester.
I asked Google AI,the title of this section and received this reply.
Highview Power’s Carrington liquid air energy storage facility in Greater Manchester is scheduled to be operational by late 2026.
The grid stabilization phase is set to begin early in the year, with full long-duration operations following shortly after.The £300 million project at the Trafford Low Carbon Energy Park is a pioneering commercial-scale “cryobattery” that liquefies and stores air to capture excess renewable energy.
Key details of the completed facility:
Capacity: 300 MWh of storage (delivering 50 MW for six hours)
Reach: Capable of supplying electricity to approximately 480,000 homes
Technology: Liquid Air Energy Storage (LAES)
When Will Highview Power Complete The Livingstone Battery?
Highview Power is building a300 MW/3.2 GWh liquid air battery at Livingstone near Glasgow.
I asked Google AI, the title of this section and received this reply.
Highview Power is not currently building a battery in Livingstone. They are developing a major \(2.5 \text{ GWh}\) liquid air energy storage (LAES) plant in Hunterston, Scotland, which is scheduled to come online by 2030.
According to the Highview Power web site, a 300 MW/3.2 GWh “cryobattery” is being built at the site.
How Much Offshore Wind Power Will Be Installed This Year?
In UK Offshore Wind In 2030 – Calculated May 2026, I said that 2635 MW would be commissioned this year.
Conclusion
We’re running hard, but will we keep ahead of the tsunami of offshore wind and solar panels we are installing.
In UK Offshore Wind In 2030 – Calculated May 2026, my latest calculations show that by 2036, we will have installed 61,337 MW of offshore wind alone.
How Many Of Their 300 MW/3.2 GWh Liquid Air Batteries Do Highview Power Think They Can Install?
I asked Google AI, the title of this section and received this reply.
Highview Power plans to install several of their 300 MW/3.2 GWh “Millennium Series” cryogenic plants. They are specifically developing two initial flagship sites in the UK, with the intention to scale up rapidly over the next decade to capture a significant share of national long-duration energy storage targets.
Highview Power is executing a multi-billion-pound programme to build out these multi-technology storage facilities, which combine liquid air energy storage and lithium-ion batteries.
The two primary 3.2 GWh projects advancing through the UK regulatory system include:
Hunterston, North Ayrshire (Scotland): Slated as the first of the Millennium Series, designed to provide up to 3.2 GWh of capacity (powering around 650,000 homes).It is advancing through the regulatory assessment and construction phases.
Killingholme, Lincolnshire (England): A second 3.2 GWh facility.
Both the Hunterston and Killingholme sites were deemed eligible for support under the UK government’s “cap and floor” super-battery scheme.
Two 300 MW/3.2 GWh “Millennium Series” cryogenic plants will do very nicely!
Engineering is the science of the possible, whereas politics is dreams of the impossible.
Mooir Vannin Offshore Wind Farm
This is a wind farm off the Isle of Man, that I missed as it is not on Wikipedia’s List of Offshore Wind Farms In The United Kingdom.
But it does have a web site, which has this handy map.
Note.
- The wind farm will have a capacity of 1.4 GW.
- Ørsted is building the web farm.
- It has planning permission.
- The operations base for the proposed Mooir Vannin Offshore Wind Farm will be located at Douglas Harbour on the Isle of Man.
- The Port is Owned By The Isle Of Man Government.
- Anticipated operational start date is the mid 2030s. I’ll assume 2035.
- According to the web site, connection will be to Douglas on the Isle of Man and Penwortham, Lancashire in the UK.
- Penwortham is part of Preston.
- Penwortham substation already has a 50 MW/50 MWh BESS and may get a bigger one.
- Current fossil-fuel power stations on the Isle of Man, include a number of diesel power stations and a 64 MW CCGT. They also have a 23 MW steam generator.
It looks like Mooir Vannin is large enough to give the island a carbon-free energy supply, backed up, by the UK National Grid at Penwortham.
I asked Google AI, “If The Isle of Man Was Going Into The Data Centre Business”, and received this reply.
The Isle of Man is actively positioning itself as a premier hub for data centres, tech firms, and AI companies. The government is utilizing its robust infrastructure, strong regulatory environment, and competitive tax policies to attract high-value data businesses to the island.
It also looks like they have a water system, that has a hydro-electric power-station.
Ørsted Is Danish
Ørsted is Danish and all of those countries to the North East of the UK have lots of islands.
So I asked Google AI, this question.”Does Denmark Have Any Islands With Power Stations?”, and received this comprehensive answer.
Yes, Denmark has several islands with power stations, ranging from natural islands utilizing large wind and biomass facilities to massive, pioneering “Energy Islands” built specifically as offshore power hubs.
Key Examples Include:
Bornholm (Baltic Sea): Designated as a major green “Energy Island” hub. It functions as a massive collection and distribution point for surrounding offshore wind farms, routing renewable energy to both the Danish grid and neighboring countries like Germany.
SamsØ (Kattegat strait): Known globally as a renewable energy island.
It is entirely powered by local onshore and offshore wind turbines and uses a mix of solar and battery storage systems to manage its energy needs, including marina charging.
North Sea Energy Island (VindØ): This is a colossal artificial island project (located roughly 80–100 km off the coast of Jutland) designed to act as an offshore power plant.
It acts as a hub to harvest and convert wind energy from hundreds of surrounding turbines.
Are Ørsted and Highview Power Still Talking?
In Highview Power, Ørsted Find Value In Integrating Offshore Wind With Liquid Air Energy Storage, it appeared that they still were.
As it appears that Highview Power’s Liquid Air Energy Storage can be sized to the application, I wouldn’t be surprised to see one of their batteries on an island powered by Danish wind turbines.
In Is Sumitomo Heavy Industries Highview Power Energy Storage System On Line At Hiroshima?, I describe how a Highview Power application, that uses cold, solar panels and a small Highview Power battery to increase the efficiency of a CNG Terminal.
How Many Of The UK’s Power Stations Are On Islands?
I asked Google AI this question and I received this answer.
There are three major, conventional thermal power stations on the UK’s offshore islands (two in Scotland and one in the Channel Islands), alongside several small-scale community-owned renewable plants that operate entirely off-grid.
The main island-based power stations include:
Lerwick Power Station (Shetland): A 66-73 MW diesel-fired plant commissioned in 1953. It provides a baseline of electricity for the Shetland mainland.
Sullom Voe Terminal Power Station (Shetland): An independent gas-fired station (roughly 92 MW capacity).
Its primary purpose is to serve the Sullom Voe gas terminal, but it also supplies the Shetland grid.
Queen’s Road Power Station (Jersey): A multi-engine facility in the Channel Islands that uses a mix of gas turbines and diesel generators to maintain island capacity.
(Note: Major UK islands, like the Isle of Wight, Anglesey, and the Isle of Skye, are physically connected to the mainland electricity grid via subsea cables, so they do not house their own large-scale, standalone power stations).
Beyond these conventional thermal stations, several smaller Scottish islands run on micro-grid, renewable-only power stations.
For instance:The Isle of Eigg: Powered entirely by a micro-grid of hydro, wind, and solar, completely disconnected from the UK grid.
It looks to me, that the Isle of Man, Shetland and Jersey, are the three most likely islands to get upgraded power systems and it also looks like Ørsted have the experience to make a good fist of it.
Conclusion
I have asked the question, I asked for the UK for a range of countries and I have received some interesting answers from Google AI. But the general trend seems to be to use appropriately-size medium-size and upwards, zero-carbon power stations with microgrids as on the Island of Eigg in the UK.
But I do believe that applying the technology that Ørsted, Highview Power and others are rolling out, that we can give the remote islands and places of Buckminster Fuller’s Spaceship Earth, the zero carbon power they need.
How Much B12 In A Marks & Spencer Smoked Salmon Parcel?
I asked Google AI this question and received this answer.
A standard 55g serving (one parcel) of Marks & Spencer Smoked Salmon Parcels contains roughly 2 to 3 micrograms of Vitamin B12. This single serving provides over 100% of your recommended daily adult allowance, as oily fish is exceptionally rich in this nutrient.
I usually eat two parcels a week, each on a slice of gluten-free bloomer cut into four portions, as a couple of lunches.
At Least 90 Dead In Chinese Coal Mine Explosion, State Media Reports
The title of this post, is the same as that as this article on the BBC.
This is the sub-heading.
At least 90 people have been killed in a coal mine blast in northern China, according to the country’s state media.
These two paragraphs add more detail.
The gas explosion happened at the Liushenyu Coal Mine, run by the Tongzhou Group, in Shanxi Province.
Hundreds of rescuers have been sent to the site. Footage from state media showed paramedics carrying stretchers at the site, with ambulances in the background. More than 100 people are said to have been taken to hospital, with rescue work at the site still under way.
It does seem that if you deep mine coal, you are going to get accidents. Does Opencast Coal Mining Have Less Accidents?
I asked Google AI, my question in the previous line and received this answer.
Yes, opencast (or open-pit) coal mining generally experiences significantly fewer fatal accidents than underground mining.
The primary reasons for this include better natural ventilation, better visibility, easier evacuation routes, and the absence of high-risk confined-space hazards like cave-ins, roof collapses, and toxic gas accumulations.
However, while fatal and catastrophic accidents are rarer, opencast mining introduces its own set of occupational risks:
Heavy Machinery Incidents: The use of massive excavators and haul trucks means that collisions, vehicle rollovers, and reversing accidents are leading causes of injuries.
Slope and Bench Failures: Unstable pit walls or overburden dumps can collapse, resulting in severe equipment damage and worker injuries.
Blasting Hazards: Routine use of explosives carries inherent risks, such as accidental detonation and flying rock (flyrock).
Environmental & Dust Exposure: Workers in open-cast mines can be heavily exposed to respirable silica and coal dust, which poses long-term respiratory health risks like pneumoconiosis.
It appears to me, that if you want to work in mining, you’re best option is probably to work for someone like JCB making mining equipment.
Conclusion
But then some countries put a lower value on human life than others.
I believe that what finished deep coal mining in the UK was the Aberfan Disaster in 1966, which is described in this Wikipedia entry. This is the first paragraph.
The Aberfan disaster (Welsh: Trychineb Aberfan) was the catastrophic collapse of a colliery spoil tip on 21 October 1966. The tip had been created on a mountain slope above the Welsh village of Aberfan, near Merthyr Tydfil, and overlaid a natural spring. Heavy rain led to a build-up of water within the tip which caused it to suddenly slide downhill as a slurry, killing 116 children and 28 adults as it engulfed Pantglas Junior School and a row of houses. The tip was the responsibility of the National Coal Board (NCB), and the subsequent inquiry placed the blame for the disaster on the organisation and nine named employees.
Let the Aberfan Disaster be a warning from the Welsh Valleys of the dangers of coal mining.
It is the sixieth anniversary of the Aberfan Disaster this year, so should an appropriate international ceremony be held to press home to the world, that coal mining is a disaster for the whole human race and all the other species we share our planet with.
Heathrow Expansion Could Open The Door To Five Additional UK Routes, According To New Research
The title of this post, is the same as that of this press release from the Heathrow Media Centre.
These three bullet-points act as sub-headings.
- New research identifies Belfast International, Cornwall Airport Newquay, Leeds Bradford Airport, Liverpool John Lennon and Teesside International Airport as most likely to gain Heathrow connections through expansion
- New links could unlock £335m in additional gross tourism spend, boosting trade, investment and jobs. This builds on the estimated £1.2bn in gross tourism spending across the UK from travellers supported by current Heathrow domestic routes
- Regional airports and businesses support this Government’s backing of Heathrow expansion and urge the project to be progressed as fast as possible
This is the first paragraph.
New research by Frontier Economics has identified the UK airports most likely to benefit from new or restored connections to Heathrow, when additional airport capacity is delivered by a third runway.
Surprise surprise! Research paid for by an airport shows more flights to the airport are a good idea after a new runway has been added.
I will look at each airport mentioned in the report in detail.
Belfast International
Belfast International Airport handles nearly seven million passengers a year, as opposed to the 2.5 million passengers that use the smaller Belfast City Airport.
Consider.
- Belfast International has flights to Gatwick, Luton and Stansted.
- I’ve only flown into Belfast twice and it was once to each airport.
- I did fly myself into Belfast City, when I was taking a friend to see Shorts, as he might have bought a Skyvan.
- If I wanted to go, I’d probably go from London City to Belfast City unless say, I was being picked up from Belfast International and perhaps going some distance from Belfast, in which case it would be Gatwick Airport.
- Note that I only travel with a small amount of hand baggage. As an an aside, what do travellers put in their mammoth suitcases?
- The press release talks of Belfast’s growing screen and cultural industries.
I wonder, if Belfast International needs flights from Heathrow, because there is increasing amounts of connecting travellers for Belfast and the aircraft to Belfast City aren’t large enough to carry all the cases.
Cornwall Airport Newquay
Newquay has flights to Gatwick and Stansted.
I’ve only been to Newquay once and I went by train, which I wrote about in Newquay Station – 9/10th February 2024.
- I changed once at Par.
- But soon, if not already, there will be direct trains from Paddington.
- Details on the summer-only Atlantic Coast Express are given on its Wikipedia entry.
- Will there be Pullman Dining, as I experienced on On The 10:45 From Paddington? That journey was the best train breakfast I’ve ever had!
Paddington and Heathrow isn’t a difficult journey to get the train for Newquay.
Leeds Bradford Airport
I used to fly light aircraft and I have friends in aviation. One phrase you regularly hear from pilots is “Time to spare, go by air!”
- Basically, unless you’re flying in a business jet, leave plenty of time.
- Leeds Bradford is a good airport and they did a good job, when I presented them with a problem, that I wrote about in Incident At Leeds.
- If I came into Heathrow, I would probably use Heathrow Express to Paddington and then get the Metropolitan Line to King’s Cross to get to Yorkshire.
- Leeds is also getting a Metro.
- LNER and other train companies are developing their services to the Leeds-Bradford area and there are now services to Bradford, Doncaster, Harrogate, Hull, Leeds, Shipley, Skipton and York.
- Leeds station has two trains per hour to and from London.
- Leeds station has lots of taxis.
Google AI gives this AI Overview of parking at Leeds-Bradford airport.
Parking at Leeds Bradford Airport (LBA) is highly streamlined, offering a range of on-site and off-site options. It features a popular Free 1-Hour Zone for drop-offs, premium options right outside the terminal, and competitive long-stay parking. Pre-booking online is heavily recommended to secure spaces and get the best
I doubt that flying between Heathrow and Leeds Airport will be popular, unless you’re parking at the airport
Liverpool John Lennon Airport
A lot of the things said about Leeds Bradford Airport can be said about Liverpool airport.
But Liverpool already has a comprehensive Metro.
Google AI gives this AI Overview of parking at Liverpool airport.
Parking at Liverpool John Lennon Airport is extremely convenient because all official car parks are located directly on-site within a 1 to 5-minute walk of the terminal building—meaning no shuttle buses are required.
As with Leeds-Bradford Airport, I doubt that flying to Heathrow will be popular, unless you’re parking at the airport
Teesside International Airport
Reading the Wikipedia entry for Teesside International Airport doesn’t give the impression, the airport is not in the best of health.
But this is said about parking on the Teesside International Airport web site.
Teesside Airport parking is situated directly opposite the terminal building.
Wherever you’re coming from for your flight, be it Middlesbrough, Hartlepool or down the road in Darlington, our parking is closer and safer than parking anywhere else to access the airport. It is monitored 24/7 and has been awarded safe parking status by Park Mark.
Dropping off or picking up? There’s free parking for up to two hours when you spend minimum of £5 in our Landside Café or landside terminal shops. Receipt must be shown for validation.
I suspect if you’re going to one of its eight destinations and you want to take your car, then you might use Teesside International Airport.
Although several local stations seem to have good train services to King’s Cross, it does appear that Teesside International Airport could be using parking to attract business with customer-friendly parking.
I have some thoughts.
Do Many Passengers Take A Coach To Heathrow?
Google AI gave this answer, when I asked the question in the title of this section.
Yes, absolutely. Over 5 million passengers take coaches to Heathrow every year.
The airport’s Central Bus Station is one of the busiest coach hubs in the UK, and coaches provide an incredibly popular, cost-effective alternative to trains and taxis.
The main reasons so many travelers choose to take the coach include:
Direct Terminal Access: Coaches drop you off directly at the Heathrow Central Bus Station (for Terminals 2 and 3) or right outside Terminals 4 and 5.
This saves you from dragging heavy luggage through the London Underground or navigating complex rail changes.
Cost-Effective: Advance tickets often start as low as \(£10.50\), making it substantially cheaper than black cabs, airport parking, or premium rail lines like the Heathrow Express.National Connectivity: Coaches connect Heathrow to over 500 locations across the country.
Major hubs like Bristol, Oxford, Cambridge, and Southampton have direct, frequent services without requiring a change in Central London.
Early Morning Travel: Because the airport is a 24-hour operation, many coaches run throughout the night, offering crucial connections before local trains even begin operating.
An alternative at some of these smaller airports could be better coach travel.
Is Anybody Proposing A Small Airliner Powered By Hydrogen Fuel Cells?
I believe a smaller airliner powered by hydrogen fuel cells could suit feeder flights from smaller airports.
Google AI gave this answer, when I asked the question in the title of this section.
Yes, several aerospace companies are actively developing and testing hydrogen fuel cell airliners, ranging from retrofitted commuter planes to clean-sheet regional aircraft.
The leading proposals and active development programs include:
Airbus ZEROe: Airbus is designing a 100-seat regional airliner powered by four 2.4-megawatt hydrogen fuel cell engines.
After verifying the concept’s feasibility, Airbus is currently assembling a 1.2MW powertrain demonstrator for testing, with the aircraft targeted for entry into service in the late 2030s.
ZeroAvia: ZeroAvia is focused on retrofitting existing regional airframes (such as the Dornier 228) with hydrogen-electric engines.
They are currently testing their ZA600 powertrain for 19-seat aircraft and are actively developing larger systems (up to 80 seats) to enter commercial service in the coming years.
.H2Fly: This company focuses on small regional aircraft and has test flights slated for their 4-seat air taxis and larger regional prototypes.
They advocate for starting with smaller planes to avoid the complex infrastructure challenges of larger models.
Beyond Aero: They are developing “ONE,” a hydrogen-electric business aircraft designed specifically for executive travel, aiming to reduce both costs and carbon emissions compared to traditional jet fuel.
Hopefully, hydrogen fuel cell powered aircraft will be quiet.
Could Tennis Help The Symptoms Of Uncomplicated Pancolonic Diverticulitis?
When I used to play real tennis a very regularly, I didn’t seem to get the angry gut, I have now.
I asked Google AI, the question in the title of this post and received this answer.
Yes, playing tennis can help manage the symptoms of uncomplicated pancolonic diverticulitis as part of an active lifestyle, though it is best suited for the prevention of flare-ups rather than treatment during an active attack.
Regular, moderate-to-vigorous exercise like tennis has been shown to significantly reduce the risk of developing diverticulitis.
How Tennis Helps DiverticulitisReduces Risk of Attacks:
Studies show that vigorous activity, such as tennis, can reduce the risk of developing diverticulitis by up to 27%), as mentioned in research published in the Journal of Gastrointestinal and Liver Diseases.
Improves Bowel Function: Regular exercise helps keep bowels moving, which helps prevent constipation—a major contributing factor to diverticular pain.
Reduces Inflammation: Regular, moderate-intensity physical activity (which can include tennis) has an anti-inflammatory effect on the body.
Weight Management: Exercise helps manage weight, reducing obesity, which is a major risk factor for complicated diverticular disease.
My exercise levels have certainly dropped since I had the stroke and moved to London.
Could Horseriding Help The Symptoms Of Uncomplicated Pancolonic Diverticulitis?
When I used to ride horses a small amount, I didn’t seem to get the angry gut, I have now.
I asked Google AI, the question in the title of this post and received this answer.
While there is no direct scientific evidence regarding horseriding specifically, general physical activity and exercise are strongly recommended for managing and preventing the symptoms of uncomplicated diverticulitis.
Regular exercise helps to increase bowel motility (movement), which can help reduce the pressure within the colon that contributes to diverticular symptoms.
Here is how physical activity, including potentially activities like horseriding, can play a role in managing this condition:
Benefits of Regular Exercise on Diverticular Symptoms
Reduced Risk: Studies show that regular, vigorous activity can decrease the risk of developing diverticulitis.
Improved Digestion: Exercise encourages regular bowel movements, preventing the constipation that often exacerbates diverticular pain.
Weight Management: Maintaining a healthy weight reduces pressure on the colon, which is beneficial for managing diverticular disease.
Important Considerations for Horseriding
Gentle Movement vs. Jarring: While light-to-moderate, regular activity is beneficial, you should ensure that the activity does not cause sharp pain or excessive stress on the abdominal area, especially if you have had recent symptoms.
Individual Tolerance: The key is to engage in regular exercise that you enjoy and that your body tolerates well.
When to Avoid Exercise
If you are experiencing an acute flare-up of diverticulitis (fever, severe abdominal pain), you should avoid strenuous exercise, rest, and follow your doctor’s advice, which often involves a liquid or low-fiber diet.
Could Uncomplicated Pancolonic Diverticulitis Cause The Constant Pain In My Hip Joints?
It’s not chronic pain, but I must have had it for at least forty years.
So what does Google AI make of my question?
It gave me this answer.
Yes, it is possible for uncomplicated pancolonic diverticulitis (inflammation throughout the entire colon) to cause constant pain in your hip joints.
While diverticulitis is primarily a gastrointestinal issue, it can cause referred pain to the hips and legs or trigger systemic inflammation that affects joints.
Here is how your condition might be linked to your hip pain:
1. Referred Pain (Nerve Pathway Irritation)
The inflammation from a diverticulitis flare-up can irritate nearby nerves that connect to the hip, thigh, or groin area.
Location: While classic diverticulitis causes left-side abdominal pain, a severe or widespread (pancolonic) flare can cause “referred pain” in the lower back, hip, and thigh.
Constant nature: If the underlying inflammation remains active, this pain can feel constant rather than intermittent.
2. Systemic Inflammation and “Diverticulitis-Associated Arthritis”
Rarely, active diverticulitis can trigger a form of inflammatory arthritis, acting as an extra-intestinal manifestation of the disease.
Migrating Pain: This can cause joint pain and stiffness in larger joints, including the hips, knees, and ankles.
Connection: As the gut inflammation resolves with proper care (antibiotics/diet), the joint pain often improves.
3. Anatomical Proximity
The colon sits in close proximity to the musculoskeletal structures of the pelvis, including the iliopsoas muscles (hip flexors).Inflammation in the colon can cause swelling that affects these muscles, leading to pain in the hip region, particularly with movement.
That looks like a possibility to me!
But it needs more investigation.
