Did This Get Lost In The Covids?
In October 2019, I wrote Asthma Carbon Footprint ‘As Big As Eating Meat’ and it made me think, when I just read it.
I would normally follow up a post like this, but I don’t remember doing anything like that.
The Wikipedia entry for the COVID-19 pandemic in England, starts with this paragraph.
The COVID-19 pandemic was first confirmed to have spread to England with two cases among Chinese nationals staying in a hotel in York on 31 January 2020.
It looks to me, that like everybody else in England, I had the Covids on my mind.
Is Respimat A Zero-Carbon Inhaler?
Just to be sure, I asked Google AI, the question in the title of this section and received this reply.
The Respimat soft mist inhaler is considered to have virtually no associated carbon emissions from its operation because it does not contain the high global warming potential (GWP) hydrofluorocarbon (HFC) propellants found in metered-dose inhalers (pMDIs).
While it has a substantially lower carbon footprint than traditional pMDIs, it is not strictly “zero-carbon” when considering its entire life cycle, which includes manufacturing, materials (stainless steel, aluminium, polymers), and end-of-life disposal. These factors contribute a small product carbon footprint (PCF).
According to Google AI, a reusable version is available.
A reusable Respimat device has been introduced, which further reduces the carbon footprint by up to 71% over six months compared to the disposable version because the device itself is kept longer, reducing manufacturing impacts.
Google AI says this about NHS guidance.
Health bodies like the NHS encourage the use of lower-carbon inhalers like the Respimat or dry powder inhalers (DPIs) as part of their net-zero targets, provided they are clinically appropriate for the patient.
But it does seem that Respimat devices are helping to cut global warming.
What Is The Patient Experience Of Respimat?
Google AI gave this answer to my question.
Patient experience with the Respimat inhaler is generally very positive, with high satisfaction for its ease of use, handling, and the “soft mist” it produces, leading to high continuation rates in studies; patients find it easier than many older devices and report good effectiveness, though common side effects like dry mouth, cough, and sore throat can occur.
Key Aspects of Patient Experience
- High Satisfaction: Over 85-90% of patients report being satisfied or very satisfied with the Respimat’s handling and the ease of inhaling the mist.
- Preference Over Other Devices: Many patients prefer Respimat over traditional metered-dose inhalers (pMDIs) or dry powder inhalers (DPIs), finding it easier to use and more effective.
- Soft Mist Technology: Patients appreciate the gentle, slow-moving mist, which helps deliver medication effectively and feels different from a typical puff.
- Good Adherence: High satisfaction often translates to continued use, with physicians reporting high patient adherence and continuation rates after studies end.
- Improved Technique: While initial use might need guidance, pharmacist-led interventions show significant improvements in patients’ inhalation technique over time.
That doesn’t look bad to me!
Could Immunotherapy Drugs Be Delivered By An Inhaler?
We always felt the device could deliver other drugs.
Google AI gave this answer to my question.
Yes, immunotherapy drugs could potentially be delivered by an inhaler, and this approach is a promising area of active research and development, particularly for treating lung cancer and respiratory diseases like asthma.
Rationale and Research
- Targeted Treatment: Inhaled delivery allows for high concentrations of the drug to be delivered directly to the lungs, which is particularly beneficial for treating lung-specific conditions like lung cancer or severe asthma. This localized approach aims to maximize the therapeutic effect where needed.
- Reduced Side Effects: By concentrating the medication in the lungs and minimizing its systemic absorption into the bloodstream, researchers hope to significantly reduce the severe side effects (e.g., systemic toxicity, autoimmune reactions) commonly associated with traditional intravenous or oral administration of some immunotherapies and chemotherapies.
- Patient Convenience: Inhalation is a non-invasive administration route, which is more convenient and comfortable for patients compared to injections or intravenous infusions, potentially allowing for self-administration and improving patient compliance.
The Soft Mist Technology could surely be a help!
Was Osborne Reynolds The Greatest Fluid Dynamicist?
I have to ask Google AI this question, as some of the discussions that led to creation of Respimat, took place in my house at Debach, where Osborne Reynolds had lived.
Google AI gave this answer to my question.
Osborne Reynolds is considered one of the most influential and foundational contributors to the field of fluid dynamics, though naming a single person the “greatest” is subjective. His work fundamentally shaped modern engineering and physics and remains central to the study of fluid flow today.
Key Contributions to Fluid Dynamics
Reynolds’ most significant achievements include:
- The Reynolds Number: He identified a crucial dimensionless parameter (now named the Reynolds number) that determines whether fluid flow is laminar (smooth and orderly) or turbulent (chaotic and eddying). This number is a foundational concept used across all engineering and physical sciences.
- The Theory of Turbulence: In an 1895 paper, he established the standard mathematical framework used in the study of turbulence, introducing what is known as the Reynolds-averaged Navier–Stokes equations.
- Experimental Validation: His elegant, yet simple, dye experiments visually demonstrated the transition between flow regimes, providing clear empirical evidence for his theories.
- Theory of Lubrication: He developed the Reynolds equation in 1886, which still underpins the analysis of hydrodynamic lubrication in modern bearings.
- Heat Transfer and Similitude: His research into heat transfer between solids and fluids led to significant improvements in boiler and condenser designs, and his work on hydraulic similitude enables engineers to use scaled-down models (e.g., in wind tunnels for aircraft design) to predict the performance of full-scale machines.
How Many Good Ideas Did The Covids Delay?
It could be that the roll-out of Respimat for was delayed by the Covids!
But it wouldn’t have been the only idea to have been delayed in that way!
British Strawberries In December
I purchased these strawberries at Marks & Spenbcers on Moorgate this morning.
Note.
- The packaging doesn’t photograph well.
- They were grown by the Summer Berry Co. in West Sussex.
- They also claim to be hand-picked.
- The tray appears to be made of good old-fashioned recyclable card-board.
- They are also labelled Not for EU, although they are Class 1!
I’ve eaten them before and they’re certainly good enough for this strawberry addict.
This Google Map shows the location of their strawberry fields.
The farm is located just to the North of Selsey and Bognor Regis.
Are Strawberries Good For Uncomplicated Pancolonic Diverticular Disease?
As a sufferer of the disease, I have to ask Google AI, the question in this sub-title.
This is the answer I received.
Yes, strawberries are good and safe for people with uncomplicated pancolonic diverticular disease. Current medical evidence and guidelines indicate that there is no need to avoid small seeds found in fruits like strawberries, raspberries, or blueberries.
This is the rationale
In the past, it was a common belief that small food particles like seeds could get trapped in the diverticula (the small pouches in the colon wall), causing inflammation (diverticulitis). However, this theory has been debunked by recent research.
As I’ve always preferred strawberries to an elaborate dessert, even in my friend’s Michelin-starred restaurant, I wonder, if I’ve had uncomplicated pancolonic diverticular disease for many years.
The source of the answer was from Johns Hopkins University.
Can The Signalling Of The London Overground Be Improved?
An article on Modern Railways Online is entitled First To Succeed Arriva On London Overground.
These are two paragraphs of the article.
Under the new concession, which runs for eight years, First Rail London Limited (FRLL) will introduce extra peak time trains on the Mildmay Line from May 2026, more frequent trains on the Windrush Line from December 2026 – up to 18 trains per hour – and upgrade help points and CCTV.
It will also introduce ‘targeted upgrades’ on the Mildmay Line infrastructure to “boost performance for customers.”
It would appear that the signalling is being improved.
So I asked Google AI, the question in the title of this post and received this reply.
Yes, London Overground signalling is actively being improved through major projects like the Windrush Line upgrades (aiming for 18-20 trains per hour) and South London signalling modernisation (Alstom’s new system for better reliability), allowing for increased capacity, faster journeys, and fewer delays, although these upgrades involve planned disruptive works.
It would appear that the improved signalling will lead to more faster and better services.
These have been indicated in the Modern Railways article.
- Extra peak time trains on the Mildmay Line
- More frequent trains on the Windrush Line
I would also expect more freight, open access and other special trains to be able to use London Overground tracks to pass through London.
London has a rail capacity problem, for both freight and passenger trains.
This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).
I have written a series of posts based on this report.
- Decarbonisation Of London’s Freight Routes
- Doubling Harlesden Junction
- East Coast Main Line South Bi-Directional Capability
- Gauge Improvements Across London
- Gospel Oak Speed Increases
- Headway Reductions On The Gospel Oak To Barking, North London and West London Lines
- Heavy Axle Weight Restrictions
- Kensal Green Junction Improvement
- Longhedge Junction Speed Increases
- Moving The West London Line AC/DC Switchover To Kensington Olympia
- Moving The West London Line AC/DC Switchover To Shepherd’s Bush
- Nunhead Junction Improvement
- Stratford Regulating Point Extension
- Will Camden Road Station Get A Third Platform?
- Will Clapham Junction Station Get A Platform 0?
There is certainly work to be performed on London’s railways to increase the total number of freight trains, that pass through and around the capital.
Conclusion
I believe that as has been shown on the Lizzie Line, Thameslink, the East Coast Main Line and other lines around the world, that the number of trains per hour on the Overground can be increased to meet the objectives stated in the Modern Railways article.
What Is The Peak Frequency Of The East London Line?
I asked Google AI, the question in the title of this section and received this reply.
The East London Line (now part of the Windrush Line, London Overground) has peak frequencies of around every 4-6 minutes (10-15 trains per hour) on its busiest sections, though some parts might see higher frequencies, generally offering a very frequent service through East London during peak times. Specific frequency can vary by section (e.g., Stratford-Lewisham, Canary Wharf-Lewisham), but generally, you can expect trains every few minutes during weekday rush hours (around 06:30-09:30 & 16:00-19:00).
I do think that Google AI has got its DLR and its East London Line mixed up.
But even if we accept that current East London Line service needs 15 tph and the new capacity will be the Modern Railways article figure of 18 tph, that’s still an increase of 3 tph through the Thames Tunnel-section of the East London Line.
What Is The Peak Frequency Of The North London Line?
I asked Google AI, the question in the title of this section and received this reply.
The North London Line (NLL), part of London Overground, typically runs 8 trains per hour (tph) during weekday peaks, with plans to increase this with infrastructure upgrades like digital signalling and longer trains to meet growing demand and integrate with Crossrail/HS2. While 8tph has been a target, the line also carries significant freight, impacting passenger service frequency, with older plans aiming for 6-8tph peaks and even longer trains (3-4 cars) for capacity.
The peak frequency of trains on the North London Line appears less than the East London Line, so I would assume, that like the East London Line, it could probably squeeze in another 3 tph.
When you consider that the working day is over eighteen hours, 3 tph means nearly an extra sixty trains per day on both the the East and North London Lines.
Could This Extra Capacity On The East and North London Lines Created By Improved Signalling Be Used For Extra Services?
Consider.
Every train of the service, would need its own path.
- A typical four tph Overground service like Dalston Junction and New Cross would need four paths per hour.
- A typical freight service would need a dedicated path.
- A typical long-distance passenger service would need a dedicated path.
There are certainly possibilities.
Major Revamp Of Wales’ Busiest Station Gets Go-Ahead
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Plans for a major revamp of Wales’ busiest railway station have received final approval.
These three paragraphs add more details.
The £140m upgrades to Cardiff Central – including a new brick arch rear entrance, larger concourse and improved waiting areas – aim to support passenger growth and reduce overcrowding.
Better accessibility for people with reduced mobility and additional retail and cycle facilities are also among the changes.
Work is due to start in the middle of next year with the aim of completing most of it within three years.
Note.
- The new entrance on the south side of the station, was opened in September 2015.
- A new Platform 8 was added in 2017, which allows sixteen local trains per hour to run between Cardiff Central and Cardiff Queen Street stations, to serve the twenty railway stations in the city.
- All platforms are bi-directional, which surely improves the flexibility of the rail network in Cardiff City centre.
- Access from the station to the Principality Stadium has improved greatly in recent years.
- The station will remain open during the works.
Cardiff’s railways are a comprehensive mix of local and inter-city trains.
I have some thoughts on Cardiff Station.
The Cardiff & Valleys Day Ranger
This very useful ticket, is the ideal way to explore the Cardiff and Valleys area and I’ve used it several times.
- I usually buy it from one of the two ticket offices in Cardiff Central station, but in one case, I did buy it in Paddington to save time.
- According to Transport for Wales, you can buy it on a local train from the conductor.
- It costs about £16 for an adult, but railcard apply.
I actually find taking a train up the valleys, is a good way to clean out my lungs.
Sights To See On The Cardiff & Valleys Lines
Google AI makes these suggestions.
The Cardiff & Valleys Lines offer historic castles (Cardiff, Caerphilly, Castell Coch), world-class museums (St Fagans, National Museum Cardiff, Big Pit), industrial heritage (Rhondda Heritage Park, Royal Mint Experience), and stunning nature in Bannau Brycheiniog National Park, with scenic railway journeys connecting these sites for history, culture, and outdoor adventure.
Hopefully, when the new Stadler trains and tram-trains are fully operational on the Cardiff & Valleys Lines, someone will write a full guide.
Is Formula One Likely To Go To Hydrogen Fuel?
Formula One has a long term aim of decarbonising or at least going net-zero.
I’ve never been to an electric-car race, but it must be more boring to many to have motor-racing without the smells and the noise.
I asked Google AI, the question in the title of this post and received this answer.
Formula One is unlikely to switch to hydrogen fuel in the immediate future, as its current strategy is focused on using 100% sustainable “e-fuels” from the 2026 season. However, F1 leadership has stated that hydrogen is a potential long-term solution for the 2030s and beyond.
This article on the BBC is entitled Formula 1 boss Ross Brawn Says Hydrogen Could Be Future Fuel.
But I do believe, that the trucks, vans and transporters that accompany Formula One will be decarbonised earlier and hydrogen could play a major part, due to its proven longer range.
Hydrogen coaches are being developed and could be launches next year and are likely to have a 1,000 km. range, so expect to see some of these vehicles in the fleet of vehicles following Formula One.
Hydrogen In Aviation Offers Potential For Growth And Deeper Emissions Reductions, New Study Shows
The title of this post, is the same as that of this press release from Rolls-Royce.
These five paragraphs compose the press release.
Rolls-Royce, easyJet, Heathrow and University College London Air Transportation Systems Lab (UCL ATSLab) published a report highlighting how hydrogen-powered aircraft could enable European and UK aviation to cut carbon emissions while supporting future growth.
The study, Enabling Hydrogen in the European Aviation Market, found that hydrogen in aviation offers a unique opportunity to achieve both emissions reduction and market expansion. The analysis shows that introducing hydrogen alongside Sustainable Aviation Fuel (SAF) can accelerate progress towards net zero, particularly when policy incentives reward low-carbon fuels and if hydrogen were to be included within the EU’s SAF mandate.
The research also found that targeted hydrogen infrastructure at around 20 major European airports, including Heathrow, could deliver more than 80% of the emissions benefits of full hydrogen availability across the continent. Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.
Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions, underscoring the value of early technological transition where it is financially and technically viable.
The study is underpinned by UCL ATSLab’s Airline Behaviour Model (ABM), which represents the complexity of airline decision-making through specific behavioural variables. Building on this, the research evaluates how fuel costs, incentives and new technologies shape airline responses. This provides a research-based, realistic picture of how hydrogen adoption could evolve, highlighting both opportunities and potential challenges for adoption.
Note, these two sentences recommending early adoption of hydrogen.
- Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.
- Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions.
I also suspect, that introducing hydrogen early, feeds back to reduce Co2 emissions.
But what is Trump’s considered view on hydrogen aircraft?
Google AI gives this answer to my question.
Donald Trump’s view on hydrogen for transportation, including potential use in aircraft, is highly skeptical due to perceived safety risks and effectiveness concerns, which generally aligns with his broader opposition to green energy initiatives. He has specifically criticized hydrogen-powered vehicles as being dangerous and “prone to blowing up”.
Note.
- I used to work in a hydrogen factory and it’s still producing hydrogen.
- I doubt Trump gets on well with Jennifer Rumsey, who is CEO of Cummins, who are one of the world’s largest diesel-engine companies, who are following a zero-carbon route.
- Is Formula One Likely To Go To Hydrogen Fuel? This would set the Cat Among The Pigeons
I also feel that this University College London study will create a string of converts to hydrogen.
Do Coeliacs Have More Varicose Viens?
I asked Google AI, the question in the title of this post and I received this answer.
Yes, studies suggest that people with celiac disease (CD) may have an increased risk of developing certain vein-related conditions, including a potential predisposition to varicose veins.
My mother had the worst varicose viens I’ve ever seen.
She was operated on in the 1950s, by an Indian lady surgeon, who performed her ward rounds in a sari, who my father told me, she was one of the most beautiful women, that he’d ever seen.
Although, my father was married twice, he didn’t seem to be a ladies’ man, although he had great loyalty from the ladies he employed, in his printing business. He also got on very well with my wife ; C, although they didn’t meet many times.
Is Carbon Black Used To Make Offshore Electrical Cable?
I asked Google AI, the answer to this question and received this answer.
Yes, carbon black is extensively used to make offshore electrical cables. It serves two primary functions: providing electrical conductivity to specific components and offering UV protection to outer jacketing materials.
That seems a positive answer.
It also could be a very complementary one.
HiiROC have a process that splits any hydrocarbon gas including natural gas, chemical plant off gas and biomethane, into turquoise hydrogen and carbon black.
Two methods of bringing energy to the shore from an offshore wind farm are electricity and hydrogen, through a cable or pipe respectively.
This looks to me, that there could be a possibility to use one of Baldrick’s cunning hybrid plans to bring energy onshore using both hydrogen and electricity.
Effectively, the transmission and use of the system, would use both the hydrogen and carbon black produced by HiiROC.
Artificial Intelligence To The Rescue
This evening, I had a Marks & Spencer Chicken jalfrezi with Basmati Rice for supper.
Marks put a green vegetable in the rice, which I’m not keen on as it gets stuck in the back of my throat.
So tonight, I picked it out with my hand before cooking, and put it in the food waste.
It didn’t make any difference to the cooking, but as I sat down to eat, I noticed that my right hand was going red.
As I’d never picked the dreaded green vegetable out of the rice before, I asked Google AI, if handling spices can make my hand go red and received this reply.
Yes, handling certain spices, particularly chili peppers, can definitely make your hands go red. This reaction is known as “Hunan hand syndrome” or “chili burn” and is caused by the chemical compound capsaicin.
That, certainly happened to me.
It might almost may have been worse for me because.
- My mother taught me to cook in the 1950s and she didn’t use lots of spices in her cooking. So I never learned about the dangers of spices.
- I have a leaking skin, which allows water in and out of my body easily.
- I have an immune system, like a platoon of the SAS on steroids.
So was this, why I was affected?
I then asked Google AI, “What do you do, if you react badly to chilli”, and received this reply.
If you experience a bad reaction to chili (caused by the compound capsaicin), consume dairy products (like milk or yogurt), acidic foods/drinks (lemonade or orange juice), or starches (bread or rice) for relief.
For severe symptoms like difficulty breathing or chest pain, seek immediate medical attention as it could be an allergic reaction.
For Reactions in the Mouth
The primary methods work because capsaicin is oil-soluble, not water-soluble. Water will only spread the burning sensation.
Dairy Products: Milk, yogurt, and sour cream contain a protein called casein, which acts like a detergent to strip away the oily capsaicin molecules from your pain receptors. Whole or full-fat dairy products tend to be more effective than low-fat versions.
Acidic Foods/Drinks: The acidity in items like lemon or lime juice helps to neutralize the alkaline capsaicin molecule.
Sugary Foods: A spoonful of sugar or honey can absorb the capsaicin oil and provides a distraction from the pain.
Starches/Carbohydrates: Eating plain bread, rice, or potatoes can help by creating a physical barrier and absorbing the capsaicin molecules.
Oils/Nut Butters: Capsaicin dissolves in fat. Swishing with a bit of olive oil or eating a spoon of peanut butter can help dissolve and remove the capsaicin.
For Reactions on the Skin
If you experience a burning sensation on your skin after handling chilies:
Wash the area thoroughly with dish soap and water several times, as dish soap is designed to cut grease and oil.
Soak the affected skin in milk or apply yogurt/sour cream.
You can also try a paste made of baking soda and water, or soaking the area in a diluted vinegar solution.
If the pain is severe and persistent, over-the-counter pain relievers or topical corticosteroid creams may offer relief.
When to Seek Medical Attention
While a normal reaction to chili is an intense sensation rather than actual harm, a true allergy can be serious.
Seek emergency medical care immediately if you experience:
Difficulty breathing, wheezing, or shortness of breath
Swelling of the mouth, lips, or tongue
Chest pain or heart palpitations
Uncontrollable nausea or vomiting
Luckily for me, a yogurt worked.
Conclusion
I shall use a suitable tool, like pliers or tweezers, when handling those dreaded green vegetables.
Network Rail’s Test Track Take Centre Stage As Hydrogen Is Delivered By Rail For The First Time
The title of this post, is the same as that of this press release from GeoPura.
These three paragraphs introduce the story.
Network Rail, working with rail and energy partners Freightliner and GeoPura, has transported hydrogen for the first time on Britain’s rail network, marking a major step forward for both the rail and energy sectors.
The milestone was achieved yesterday (Wednesday 3 December) at Network Rail’s Test Tracks* site in Tuxford, where freight operator Freightliner hauled a train of gas containers from Doncaster to High Marnham – marking Britain’s first shipment of hydrogen by rail.
It was part of a rail and energy industry innovation event showcasing several hydrogen initiatives. This included the first re-engineered hydrogen-powered shunting locomotive – seen as a step towards replacing diesel – another milestone towards the rail industry’s goal of becoming net zero. The event also demonstrated HPU hydrogen-powered generators, lighting towers and support vehicles.
These two paragraphs describe Network Rail’s test track at Tuxford and GeoPura’s hydrogen production facility at High Marnham.
Network Rail’s site at Tuxford runs all the way to High Marnham, where it sits adjacent to HyMarnham Power, the UK’s largest green hydrogen production facility operated by GeoPura and JG Pears. Built on the site of a former coal-fired power station, HyMarnham Power is one of the world’s first rail-connected hydrogen production facilities, and Network Rail’s Tuxford site will be the world’s first net-zero railway testing facility.
Currently, hydrogen is transported by road. This breakthrough marks a major step towards the rail network becoming a ready-made hydrogen distribution system, a rolling pipeline, with connections to all major industrial and urban centres across Britain – proving the practical capability of rail to transport hydrogen at scale. Hydrogen will also be utilised to decarbonise wider rail operations, from construction to ongoing maintenance and off-grid operations.
This OpenRailwayMap shows Tuxford and High Marnham.
Note.
- The blue arrow is Tuxford West junction.
- The North-South red track is the East Coast Main Line. East-West track indicated by the blue arrow is Network Rail’s Test Track
- The grey area, to the South of the Test Track in the East is the former site of High Marnham power station, where GeoPura have their hydrogen facility.
- If you continue East on the Test Track it connects to the Sheffield and Lincoln Line at Pye Wipe junction.
Sheffield could be the sort of city, that would need a lot of hydrogen to decarbonise.
Has Hydrogen Been Transported From ICI’s Former Site At Runcorn By Rail
I ask this question, as I used to work at Runcorn in the 1960s, and I don’t remember seeing any hydrogen railway wagons.
I asked Google AI, the question in the title of this section and received this answer.
Hydrogen is typically transported from the INEOS (formerly ICI) site in Runcorn via pipeline or by road in cryogenic liquid tanker trucks or gaseous tube trailers, but it has not been historically transported by rail from that specific site.
The first ever trial shipment of hydrogen by rail on Britain’s network took place only very recently, in December 2025, as part of an industry innovation event. This trial involved transporting hydrogen containers from Doncaster to High Marnham, adjacent to the HyMarnham Power green hydrogen production facility.
It looks like my memory and Google AI agree.
The Anonymous Widower
