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!
Managing Earthworks In A Changing Environment
This image shows the train derailment at Shap at 06:10 on Monday.
The BBC and others were talking about the cause of the derailment being a landslide.
So it was perhaps appropriate that the latest edition of Rail Engineer had a sponsorsed feature with a title of Managing Earthworks In A Changing Environment.
It is well-worth a full read.
What Happened To The Toyota Hydrogen-Powered HiLux?
I wrote about this vehicle in Toyota Unveils Prototype Hydrogen Fuel Cell Hilux, but I’ve not heard any more.
So I asked Google AI, the question in the title of this post and received this reply.
The Toyota hydrogen-powered Hilux is currently in the demonstration and evaluation phase and has not been officially confirmed for mass production. Ten prototypes were built in the UK and are undergoing testing, with some being used for customer and media demonstrations at events like the Paris Olympics. Toyota is using this project to gather data, refine its hydrogen technology, and prepare for a future European market that could see the vehicle go on sale around 2028.
A simple Google search produced this YouTube video and this article in the Toyota UK magazine.
I don’t want to drive one, as that would be illegal, but I have just added riding in one of these beasts to my bucket list.
Toyota Have Gone To The Advanced Propulsion Centre For Their Latest Project
In Toyota Leads Multi-Million-Pound Micromobility Research Project, I write about another project, where Toyota have approached the Advanced Propulsion Centre for funding and technical help. So the Advanced Propulsion Centre must be doing something right, to attract another project from Toyota.
In CoacH2 – The Next Generation Coach, I write about how the Advanced Propulsion Centre are helping to develop the powertrain for Wrightbus’s upcoming hydrogen-powered coach.
It certainly looks like the Advanced Propulsion Centre are in the middle of the net-zero transport revolution.
Conservatives Would Scrap Stamp Duty, Badenoch Announces
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
The next Conservative government would abolish stamp duty on the purchase of main homes, Kemi Badenoch has said, in a surprise announcement at the end of her first conference speech as party leader.
These two introductory paragraphs add more detail.
Badenoch received a standing ovation from Tory activists in Manchester as she declared: “That is how we will help achieve the dream of home ownership for millions.”
She said scrapping stamp duty – a tax paid by home buyers in England and Northern Ireland – will “unlock a fairer and more aspirational society” and help people of all ages.
Note.
- I have a degree in Control Engineering at Liverpool University and graduated in 1968.
- Badenoch has a degree in Systems Engineering at Sussex University and graduated much recently.
Our degrees are both very mathematically-based and probably surprisingly similar.
My feeling as a Control Engineer, is that to selectively remove stamp duty could be a good idea, as you are affecting the derivatives rather than the rates.
Only time will tell, but some thorough mathematical modelling will probably show the validity of the idea.
It is unlikely that I will move, but given the state of the buses, there is a small chance that I might.
- My current house is probably worth about a million.
- If I bought a similarly-priced house, I would pay tax of £43,750.
- But, if I bought a house at double the price, I would pay tax of £153,750.
Given the progressive nature of the tax, I think I’ll be staying put, occupying a three-bedroom family house with a garage, all by myself.
If the tax is removed, I would be more likely to move into a house, that suited me better!
Historic Church Tower Suspended On Stilts To Make Way For London Skyscraper
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
The remaining part of the 700-year-old All Hallows Staining, off Fenchurch Street, will be the centrepiece of the public square below Axa’s £1 billion office
These three paragraphs add more details.
A700-year-old church tower is being suspended on 45ft stilts while developers clear the ground beneath to make way for the City of London’s newest skyscraper.
The tower, which is all that remains of All Hallows Staining close to Fenchurch Street station, is being preserved and will be the centrepiece of the public square at the base of 50 Fenchurch Street — the £1 billion office tower being built by the investment arm of Axa, the French insurer.
More than 125,000 tonnes of earth has been cleared from underneath and around the church — which survived the Great Fire of London in 1666 — into which the foundations will be laid and a basement level built.
The Wikipedia entry for All Hallows Staining, starts with this paragraph.
All Hallows Staining was a Church of England church located at the junction of Mark Lane and Dunster Court in the north-eastern corner of Langbourn ward in the City of London, England, close to Fenchurch Street railway station. All that remains of the church is the tower, built around AD 1320 as part of the second church on the site. Use of the grounds around the church is the subject of the Allhallows Staining Church Act 2010 (c. v).
Note.
- The Wikipedia entry gives a lot of history and other details about the tower.
- It was named “Staining”, which means stone, to distinguish it from the other churches of All Hallows in the City of London, which were wooden.
- The old church survived the Great Fire of London in 1666 but collapsed five years later in 1671.
- The church appears to have been cheaply rebuilt in 1674.
- In 1870 the parish of All Hallows Staining was combined with that of St Olave Hart Street and All Hallows was demolished, leaving only the tower.
- All Hallows Staining seems to have survived World War Two, but St Olave Hart Street suffered serious damage.
- Between 1948 and 1954, when the restored St Olave’s was reopened, a prefabricated church stood on the site of All Hallows Staining. The tower of All Hallows Staining was used as the chancel of the temporary church.
- The remains of All Hallows Staining were designated a Grade I listed building on 4 January 1950.
The tower of All Hallows Staining seems to have a very strong survival instinct.
This web page gives more details of Fifty Fenchurch Street,
This morning, I went to take some pictures of the tower and the construction site.
Note.
- I walked around the site from the forecourt of Fenchurch Street station.
- The last three pictures were taken from the top deck of a Westbound 25 bus.
- There appears to be no accessible bar or roof-top from which you can look down on the site.
So for the present time, the 25 bus seems to give the best views.
This afternoon, I took a train to Fenchurch Street station and looked at the Eastern and Northern sides of the site.
Note.
- The first picture was taken through the upper windows of the front of Fenchurch Street station.
- I think I might have got a better view out of the window of Fenchurch Street station, if Great Socialist Railways had cleaned the windows.
- In pictures three to nine, the “Walkie-Talkie” towers over All Hallows Staining.
- Some pictures were better than those I took in the morning, as the truck had moved.
- The last picture shows the sign for the Garden at 120.
The area isn’t short of geometric shapes to photograph.
Raft Of US-UK Nuclear Deals Ahead Of Trump Visit
The title of this post, is the same as that of this article on World Nuclear News.The article is a good summary of all the deals done between the US and UK governments concerning next-generation nuclear power.
This is the introduction.
Several agreements have been signed between UK and US companies to advance the deployment of small modular reactors and advanced reactors in both countries. The deals were signed ahead of the state visit of President Donald Trump to the UK later this week.
The whole article is a must-read.
These are my posts, that are related to the main agreement.
- Centrica And X-energy Agree To Deploy UK’s First Advanced Modular Reactors
- Nuclear Plan For Decommissioned Coal Power Station
- Rolls-Royce Welcomes Action From UK And US Governments To Usher In New ‘Golden Age’ Of Nuclear Energy
I shall finish it later.
Desperate Times Call For Desperate Measures
The title for this post was inspired by this article on the BBC, which is entitled Water Scheme Kicks In To Boost Severn Amid Drought.
This is the sub-heading.
A groundwater scheme in Shropshire that pumps additional water into the River Severn has been switched on
These are the first three paragraphs, which add more detail.
It comes after the Environment Agency (EA) last month declared drought status for the West Midlands, following the driest spring in 132 years.
The scheme, owned and operated by the agency, pumps groundwater stored naturally in sandstone underneath much of north Shropshire, and delivers it through an underground network of pipes into the Severn.
The scheme pumps almost 40 Olympic-sized swimming pools of fresh water every day into the river, with a total of 49 pumps and 53km (32.9m) of underground pipes.
It looks a good scheme to me, but I suspect, those pumps and pipes didn’t come cheap.
These two further paragraphs, explain how it works.
Two reservoirs in Wales – Clywedog and Vyrnwy – are the first resources used to top up the river during dry weather.
The groundwater scheme is the last option to be brought into operation during dry conditions, because of how resource-intensive it is.
I suspect politicians like Trump and Farage would not have sanctioned a scheme like this, as it only protects a river.
This page on the Environment Agency blog gives more details of the scheme.
I looked up the title, that I’ve used for this post on Google AI and received this answer.
“Desperate times call for desperate measures” is an idiom suggesting that unusual problems or difficult circumstances may require unconventional or extreme solutions that would not normally be considered. The phrase originated from an ancient Greek physician, Hippocrates, who wrote about extreme diseases needing extreme methods of cure. The saying acknowledges that when faced with significant challenges, bold or drastic decisions may be necessary for survival or success.
As it seems the scheme is working well, I feel that the decision to build it, was the right one.
HMP Highpoint Launches Rail Engineering Apprenticeships To Reduce Reoffending And Address Skills Gap
The title of this post, is the same as that of this article on Railway Gazette.
This is the sub-heading.
A programme of railway engineering apprenticeships has been launched at Highpoint prison in Suffolk in partnership with The Co-operative Group retail and consumer services business and the City & Guilds Foundation.
These first two paragraphs add more detail.
From August, the training programme will allow prisoners to complete full apprenticeships and end-point assessments before release.
The initiative has been set up partly in response to Co-op members’ requests at its AGM for the business to focus on reducing re-offending and supporting prisoner rehabilitation. It is intended to give offenders the chance to earn a Level 2 qualification as Rail Engineering Operatives, with the aim that they can move straight into employment and into trackside roles on release.
I should say, that I know HMP Highpoint well, as it was close to where I lived in Suffolk and I had the occasional drink with some of the prison staff at a local pub. One even encouraged me to apply to be a member of the Internal Monitoring Board for the prison. Sadly, I had the stroke and was unable to follow it through.
I am all for this initiative, especially as it seems to offer employment on release. A similar train and employ policy doesn’t seem to have done Timpsons any commercial harm.
The only problem of running this course at HMP Highpoint, is that the prison, is not near a railway line.
In the selection process for the Internal Monitoring Board, I had a tour of the prison.
One member of staff, who ran a course on recycling told me that his course was the most popular in the prison.
- The main part of the course was about sorting rubbish into what can be recycled and what couldn’t.
- The course was popular, as most companies, who were involved in recycling, needed operatives who do this efficiently, so it helped getting employment on release.
It also had a big side effect, in that the prison was very clear of litter.
This course surely had similar objectives to the new Rail Engineering Operatives course and the Timpsons training.
We need more initiatives like this in our prisons.
Disused Oil Wells Could Enhance Compressed Air Storage
The title of this post, is the same as that of this article on The Engineer.
This is the sub-heading.
A new study has shown how geothermal energy in abandoned oil and gas wells can boost the efficiency of compressed air energy storage by nearly 10 per cent.
These are the first two paragraphs.
Developed by researchers at Penn State University, the geothermal-assisted compressed air energy storage (GA-CAES) system harnesses the existing infrastructure of abandoned oil and gas wells (AOGWs). Compressed air is pumped into the wells, where geothermal heat raises its temperature and compresses it further. Published in the Journal of Energy Storage, the study showed how geothermal energy could increase round-trip efficiency by 9.5 per cent.
“This improvement in efficiency can be a game changer to justify the economics of compressed-air energy storage projects,” said corresponding author Arash Dahi Taleghani, Professor of Petroleum and Natural Gas Engineering at Penn State.
The Professor also says it could be a “win win situation!”
Trump must have nightmares about stories like this, especially, when the scientists have a name, that labels them as an immigrant.
Ricardo Signs Deal To Support Singer With Bespoke Manual Transmissions
The title of this post, is the same as that of this press release from Ricardo.
These three paragraphs give more details of the deal.
Ricardo, a global strategic, environmental, and engineering consulting company has signed a deal to supply bespoke, manual transmissions to Singer’s operations in the US and UK.
The transmissions will be exclusive to Singer and will initially be available to owners who request Singer’s Classic Turbo or DLS Turbo restoration services for their Type 964 Porsche 911.
Singer arrived on the automotive scene with their Classic services in 2009. Since then, the company has developed restoration services allowing owners to personalise both naturally aspirated and turbocharged cars. A Porsche 911 Reimagined by Singer is a rare machine, bringing together iconic design with twenty-first century engineering and material science.
I owned two Porsche 911s. The picture shows my 1969, 911T on the Isle of Skye.
I last heard of it about thirty years ago and it was still going strong in New Zealand.
Are Classic Cars The Future?
Seeing that top-class engineering companies, such as Ricardo, are getting involved, does it mean that rather than drive around in soulless electric cars, drivers will prefer something more interesting.
The Singer web site, certainly has lots of images of Automotive Pornography.
