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.
One Of The Jobs I Did, That I’m Most Proud Of
In the early 1970s, I developed and attempted to market a simultaneous differential equation solving program called SPEED, which stood for Simple Program for the Efficient Evaluations of Differentials or something like that.
It wasn’t very successful, but two companies asked me to write some for them.
- For Time Sharing, I put the central algorithm into their simultaneous differential equation solver to move the program up to the next level.
- WS Atkins, asked me to install it on their computer.
SPEED had a few advantages over typical simultaneous differential equation solvers of the time like IBM/CSMP.
- IBM/CSMP needed at least an IBM 360/50 computer, which I ran it on at ICI in Welwyn Garden City, where I was a general mathematical dogsbody. But SPEED could run on a dial-up line to a time-shared computer like a PDP-10.
- The time-shared computers as used by Time Sharing and WS Atkins, gave the big advantage, that as the size of the computer increased, the size of the problem, that could be tackled in proportion.
- IBM/CSMP and SPEED both had a simple column-oriented report writer, which unsurprisingly ended up in Artemis, which I wrote a few years later.
- I can’t remember, who at ICI gave me the tip, but I used a sophisticated version of the Runga-Kutta algorithm, that everybody used and some probably still do today. The version, I used was called Runga-Kutta-England, where like me England, was a graduate of Liverpool University.
This summary by Google AI described the algorithm.
The England version of the Runge-Kutta method (developed by R. England) is a highly efficient 4th/5th order embedded numerical integration formula. By reusing intermediate slopes across two methods of differing orders, it provides a highly reliable built-in error estimate for adaptive step-size control.
Does anybody still use Runga-Kutta methods? I suspect not!
A breakthrough of sorts came, when WS Atkins asked me to produce a larger system of the SPEED software, that could handle several tens of thousands of equations.
- Atkin’s client was the Water Resources Board and they were modelling the water distribution system for a large part of the UK.
- Prominent in the project was a Dr. David A, Dimeloe and we became friends and had dinner with our wives a couple of times.
- But I never received a copy of the report, that was written or heard any more since about 1975.
- But judging by the fact, that we seem to have adequate supply of water in the UK and problems seem to be all about sewage, politics, management and finance, I feel that David and his team, must have done a good job.
- I was also never asked to fix any bugs in the software.
I did have some trouble getting the money I was owed from the intermediary in the deal, but I eventually retrieved it through the County Court without a solicitor.
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?
Crown Estate’s Revenue From Existing Offshore Wind Farms 20 Pct Higher, Operating Profit Dips As Round 4 Projects Enter Construction Phase
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Crown Estate reported a decline in annual operating profit to GBP 1.2 billion (approximately EUR 1.4 billion) from GBP 1.4 billion (approx. EUR 1.6 billion) in the previous year due to lower offshore wind Round 4 option fee income, as the Round 4 projects started entering the construction phase. Excluding the Round 4 option fees, operating profit rose 5 per cent to GBP 370 million (approx. EUR 435 million), while revenue from existing offshore wind farms increased 20 per cent to GBP 117 million (approx. EUR 138 million)
These four paragraphs add more details.
Over the year, the Crown Estate returned GBP 487 million (approx. EUR 573 million) to HM Treasury, bringing total contributions to GBP 5.1 billion (approx. EUR 6 billion) over the past decade, according to its financial report released on 25 June.
Alongside the financial results, the UK seabed manager highlighted that offshore wind capacity in its waters has reached 13 GW, up from 12 GW, with 36 wind farms now operating in its marine portfolio.
The pipeline of offshore wind capacity has increased to 56 GW, with an expanding offshore leasing and development programme as early Round 4 projects enter construction.
In the Offshore Wind Seabed Leasing Round 4, held in 2021, the Crown Estate selected six projects, which signed their Agreements for Lease in 2023, kicking off the three-year period during which the developers were paying annual option fees.
In Offshore Wind In 2030 – Calculated June 2026, I showed that the offshore wind capacity will have increased to 56 GW, sometime in 2031-2032.
How Much Income Will There Be In 2027-2032 from UK Wind Farms?
I asked Google AI the question in the title of this section and received this answer.
UK wind farm industry revenues are forecast to surpass £6 billion annually heading into 2027, driven by expanding capacity and inflation-adjusted contracts. Between 2027 and 2032, overall sector income will scale rapidly as capacity aims to double and up to £5 billion is pumped into the supply chain.
The economic landscape for UK wind generation features the following financial projections and parameters:
Industry Revenue & Growth: The UK wind power generation market is projected to expand at a Compound Annual Growth Rate (CAGR) of over 15% through 2031. The rapid expansion of both onshore and offshore capacity will push total market revenues well into the double-digit billions by 2032.
Contract for Difference (CfD) Revenues: Wind farms are heavily shielded from market volatility by index-linked strike prices. For instance, recent offshore projects have secured delivery rates as low as $37.35 per megawatt-hour (MWh). Conversely, older assets are transitioning out of initial subsidy schemes, moving into merchant wholesale pricing or new contracts by 2027.
Macroeconomic Contribution: Every additional gigawatt (GW) of offshore wind capacity adds an estimated £2 billion to £3 billion to the wider UK economy.
The Crown Estate Earnings: Acting as the UK seabed manager, The Crown Estate generates significant income from offshore wind leasing, having reported operating profits of over £1.2 billion and planning to retain up to 60% of its revenue to reinvest in the energy sector.
Landowner & Community Economics: For utility-scale farms, participating landowners generally earn between 5% and 6% of the annual turnover from wind farms, equating to around £40,000 per year for a single large turbine. Domestic turbines can earn up to £702 annually under the Smart Export Guarantee (SEG), depending on the specific supplier tariff.
I believe that with a similar growth of solar energy, the renewable energy produced in the UK in 2032 will be beyond our wildest dreams.
Was There Often A Barrel Of Beer Available In Places Like Foundries, Where The Work Was Hot And Hard?
Readers of The Times has been discussing electrolytes in this hot weather and especially the possibility that beer contains electrolytes.
This was posted.
My elder father informed me yesterday his fridge is full of alcohol free Erdinger wheat beer. It is marketed as good for replacing electrolytes.
So there could be something in it.
At the moment, as I type this the temperature is 35.5 degrees and the humidity is 26%, so I’m finishing off last night’s bottle of Adnam’s Ghost Ship Alcohol-Free 0.5 % Beer.
I asked Google AI, the question in the title of this post and received this reply.
Yes. In heavy industries like foundries, glassworks, and steel mills, consuming large volumes of liquid was a medical necessity to replace what was lost to sweat. Historically, workers frequently supplemented their diets with beer—sometimes supplied by the company, sometimes delivered by local pubs, and sometimes factored into their pay.
Historical Context & Working Conditions
The Thirst Quenchers: In sweltering industrial environments where temperatures could exceed \(65^{\circ }\text{C}\) (\(150^{\circ }\text{F}\)), workers suffered massive fluid loss. A furnaceman or steelworker could sweat out up to twenty pints a day.
The “Beer Allowance”: In places like Britain’s steelworks in Sheffield, it was customary for workers to receive a weekly beer allowance—sometimes up to forty pints—often supplied directly to the sweltering factory floor via young workers known as “bucket boys”.
Liquid Nutrition: Before the advent of modern refrigeration and reliable municipal water, low-alcohol table beer provided crucial calories and hydration without the risk of waterborne illnesses. It was treated more like a food source than an intoxicant.
The Shift to Modernity
The Temperance Movement: The availability of alcohol at work gradually changed during the 19th and 20th centuries. The rise of the Temperance Movement and stricter workplace safety regulations meant that by the mid-to-late 20th century, foundries began phasing out alcohol in favor of safer, hydration-focused alternatives.
Modern Replacements: Today, foundries and heavy industries prioritize hydration through water, electrolyte replenishment, and salt tablets rather than on-site alcohol.
I should say, the following.
- My paternal grandfather was an alcoholic and it eventually caused his early death at around 40.
- I lose a lot of water through my skin. See My Strange Skin.
- I’ve always preferred beer to any other drink. But I’ve never had an alcohol-related problem.
So do I drink beer and usually real beer because of its electrolytes?
Centrica Energy Agrees 10 Year Gas Supply Deal With Peyto Exploration & Development Corp
The title of this post is the same as that, as this press release from Centrica.
This is the sub-heading.
Centrica Energy has announced the signing of a long-term natural gas purchase agreement with Peyto Exploration & Development Corp., a leading Canadian natural gas producer.
These three paragraphs add more details.
Under the agreement, Peyto will deliver 50,000 MMBtu of natural gas per day to Centrica Energy over a 10-year period from 2029, equivalent to approximately five LNG cargoes annually.
Deliveries will be made at the NIT “AECO” hub operated by TC Energy in Alberta, Canada. The gas will be priced against the Title Transfer Facility (TTF), the benchmark for European gas markets. This agreement supports Centrica Energy’s strategy of strengthening its LNG portfolio through long-term, LNG-linked gas supply arrangements.
By linking feed gas pricing to European benchmarks and maintaining flexibility across global markets, the deal enhances Centrica Energy’s ability to manage market exposure and optimise its LNG portfolio.
It seems a deal that has been structured to avoid risk.
Andy Burnham Promised 10,000 Council Houses. Guess The Tally So Far
The title of this post, is the same as that, of this article in The Times.
This is the sub-heading.
Greater Manchester is a success story but that has little to do with the mayor, still less the economic model he is touting for the country
These are the first two paragraphs.
I don’t like being mean to Andy Burnham. With his soft, doe-eyed features, it feels rather like punching a lamb. But it’s quite an achievement when “We’ve got to get beyond this thing of being in hock to the bond markets” isn’t actually the stupidest thing a politician has said in any given week.
The other day Burnham kicked off his not-quite-a-leadership bid by urging Labour to embrace “Manchesterism”. This he defined as “business-friendly socialism”, in which the state “rolled back the 1980s” by seizing control of “the basics of life”: housing, energy, water, rail. This included borrowing £40 billion for new council housing.
This paragraph from Robert Colville gives the current progress on housing in Manchester.
Burnham did announce, in May 2024, that he was going to build 10,000 council houses by 2028. But over the following year the region started construction on just ten. No, that’s not a typo.
That is not a good start!
SSE Energy Solutions Powers Ascot’s Shift To Electrification With One Of UK Sport’s Largest Rooftop Solar Projects
The title of this post, is the same as that of this press release from SSE.
The press release starts with these three bullet points.
- System expected to generate approx. 569,000 kWh of renewable electricity annually, reducing reliance on fossil fuel power
- Installation to supply around 9% of Ascot’s annual electricity needs
- Helps improve energy resilience and cost predictability through on-site generation
These first two paragraphs add more details.
Ascot Racecourse has taken a major step in electrifying its operations with the completion of a large rooftop solar installation, delivered in partnership with SSE Energy Solutions and Ortus Energy. The system, installed across the 480-metre Grandstand roof, includes more than 1,200 solar panels and has a total capacity of 608.04 kWp.
Once fully energised, the project is expected to generate approximately 569,000 kWh of renewable electricity each year. The electricity will be used on site to help power race days, including Royal Ascot, as well as more than 180 non-racing events hosted at the venue annually. By generating electricity at source, Ascot can reduce its reliance on grid electricity generated from fossil fuels and strengthen the resilience of its operations.
The installation will meet around 9% of Ascot’s total annual electricity demand.
I have a few thoughts.
The Scheme Is Delivered Via A Long-Term Power Purchase Agreement
This is the last paragraph of the press release.
Delivered via a long-term power purchase agreement (PPA), the project requires no upfront capital investment from Ascot. SSE Energy Solutions funds the installation, while Ortus Energy designs, installs and operates the system — enabling Ascot to access renewable electricity with long-term price visibility and reduced exposure to volatile fossil fuel markets.
It looks like King Charles III, who owns Ascot racecourse, hasn’t had to put any cash up front.
What Is The Capacity Of Ascot Racecourse?
Google AI said this.
Ascot Racecourse has a maximum race-day capacity of 70,000 guests, which was reduced from 80,000 to manage crowd density and improve the overall customer experience. The venue is divided into several enclosures, each with its own limit to maintain a comfortable environment during premier events like Royal Ascot.
It may be only the third largest horse racing venue in the UK, but it is probably larger than most sports stadiums.
Which Other Stadiums Have Or Plan To Have Solar Panels In The UK?
A quick use of Google AI found these.
- Hampshire Cricket Stadium
- London Stadium
- Principality Stadium
- Queen’s
I suspect this list could grow fairly quickly.
Could SSE Be Using Ascot Racecourse To Sell Solar Roofs?
Consider.
- Ascot racecourse is one of the most prestigious venues in the UK.
- Ascot racecourse has its own dedicated railway station.
- There are twenty-six race days per year.
- Both codes of horse-racing are featured.
- Some meetings are followed by live music.
- I suspect flying drones about the stands to show off the solar panels could be arranged.
- Catering should be top notch.
- Everything for a high-class sales-presentation should be available.
Ascot racecourse could be an ideal venue to sell large solar roofs to owners of sports stadia or other large buildings.
Will The Real Andy Burnham Please Stand Up!
As I wrirw posts in the next couple of weeks, if I find Andy Burnham has said something about the subject, that is worth adding, I will add it.
TerraLithium, BHE Renewables Announce Key Milestones For Geothermal Lithium Project In California
The title of this post, is the same as that of this article on ThinkGeoEnergy.
This is the sub-heading.
TerraLithium and BHE Renewables have announced key milestones towards advancing technology for lithium extraction from geothermal brines in Imperial Valley, California.
This is the important paragraph in the article.
The business model of coupling lithium and critical minerals extraction with geothermal energy production is gaining increasing attention, both in the United States and in countries like Germany, France, and the UK. As demonstrated in the United Downs geothermal power project in Cornwall, lithium extraction provides additional revenue generation that can significantly improve the economics of deep geothermal projects.
So here we have little Cornwall showing Big California how to get power and lithium out of hot rocks.
In Cornish Plant Produces Geothermal Power, I described the progress at the Cornish plant in March.
Has Andy Burnham Ever Said Anything On Geothermal Energy?
Given that there is an election or coronation under way, I just had to ask Google AI, the question in the title of this section.
This is the answer I received.
Yes, Andy Burnham has occasionally engaged with topics involving geothermal energy, particularly in the context of tapping natural underground heat and mine water for green energy
His notable references to the technology include:
Supporting Manchester’s Geothermal Potential: He has voiced support for localized renewable heat projects, such as exploratory borehole plans in Manchester city centre intended to tap into thermal springs for community heating.
I think we can put that down as a favourable view.
This excellent article on the BBC is entitled Plan To Heat Manchester Homes With A Geothermal Spring, is worth a full read.
