Data Centre In The Shed Reduces Energy Bills To £40
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
An Essex couple have become the first people in the country to trial a scheme that sees them heat their home using a data centre in their garden shed.
These three introductory paragraphs add some detail.
Terrence and Lesley Bridges have seen their energy bills drop dramatically, from £375 a month down to as low as £40, since they swapped their gas boiler for a HeatHub – a small data centre containing more than 500 computers.
Data centres are banks of computers which carry out digital tasks. As the computers process data, they generate lots of heat, which is captured by oil and then transferred into the Bridges’ hot water system.
Mr Bridges, 76, says keeping his two-bed bungalow near Braintree warm was a necessity as his wife has spinal stenosis and is in “a lot of pain” when it gets colder.
I think this simple idea is absolutely brilliant and very technically sound.
Here are some further thoughts.
It Would Be Ideal For A House Like Mine
My house is a modern three-bedroomed house with a garage and when I asked Google AI how many UK houses had garages, I received this answer.
Approximately 38% of dwellings in England have a garage, according to a 2020 report. While a specific UK-wide figure is not available, extrapolating this percentage to the total number of UK dwellings suggests there are over 10 million houses with garages, though the actual figure may vary across different regions.
Looking at the picture in the BBC article, I feel that this HeatHub could fit in my house.
I would expect that any house with a garage, a small garden or a big enough boiler space could accommodate a HeatHub.
Obviously, the house would need.
- A boiler, that provides heating and hot water.
- A good broadband connection.
My house has both.
Would My House’s Heating System Need To Be Modified?
It looks like it’s just a boiler replacement, so I don’t think so, but it may need to be moderbnised with digital controllers to get the best out of the system.
Will There Be Other Systems Like Thermify’s Heat Hub?
Some of our electricity suppliers seem very innovative and the market is very competitive.
Would they just sit back and let coompetitors take their customers? I doubt it!
So I suspect there will be other systems, each with their own features.
I have already, written about heata, which uses similar principles to give affordable hot water in British Gas Partners With heata On Trial To Reuse Waste Heat From Data Processing.
The BBC article gives some examples of data centres used to provide heating, so it is worth reading the full article.
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!
My 78-Year-Old Legs Are More Reliable Than The New Chinese Buses On London’s 141 Bus Route
So we all know what we’re talking about, here’s a few pictures.
Note.
- The buses seem to have no serious faults from a passenger point of view.
- One middle-aged lady on the plump side, said she didn’t like the buses.
- The aisle between the front seats doesn’t seem to be built for large people.
- The seats are reasonably comfortable.
- One morning, I stood on a long journey and I felt the road-holding wasn’t as good as a New Routemaster.
- On several buses, the interior route display has not been working.
- As I don’t wear a watch, I find a non-working display annoying.
- I haven’t been upstairs yet.
- As picture numbers three and four show, the bus looks a bit pokey at the back downstairs.
But I am very suspicious about the buses’s reliability or ability to handle the route, which is fairly long.
Take this morning, when I was coming home from London Bridge station.
- There was only a 43 bus at the shared stop with the 141 bus.
- As the routes are identical until Old Street station, I took the 43 bus to Moorgate station.
- At Moorgate station, I took a 76 bus, which gets me within walking distance of where I live.
- Someone said, that a 141 bus would mean a wait of ten minutes.
- In the end my 78-year-old legs delivered be home.
I didn’t see a 141 bus going my way on my journey.
I have seen behaviour like this several times, since some Chinese electric buses were introduced on to the route.
As a graduate Electrical and Control Engineer, it looks to me, that there is one of two problems with these buses.
- The batteries aren’t large enough for the route.
- Not enough time is allowed for charging the batteries at the end of the route.
This page on the Wrightbus website is entitled Wrightbus Electroliner ‘Most Efficient Double-Deck Battery-Electric Bus’, and it contains this paragraph, which probably explains their philosophy and ambition.
We have already gained a strong reputation for our hydrogen double deck but we want to lead the world in zero-emissions full stop. Wrightbus has the best brains in the business when it comes to technology and our StreetDeck Electroliner puts us squarely at the front of the pack. We haven’t weighed the bus down with a high battery volume just so we can say it’s got the most power or range; instead, we’ve made it the most efficient vehicle on the road by combining optimum power with a class-leading rapid charge, meaning our electric bus spends more time on the road than any other.
It also probably sets a very high bar, which the Chinese can only achieve by adding battery volume and making their buses pokey.
To be fair to the buses, the 141 route is probably nearly 20 miles long.
In Sutton Station To Gatwick Airport By Hydrogen-Powered Bus, I wrote about what it says in the title.
In that post, I said this about hydrogen buses running on the 141 route.
Wrightbus Hydrogen Buses For My Local Bus Route 141
Consider.
- The 141 bus route is my local bus, which gets me to Moorgate, Bank, London Bridge and Manor House.
- The length of the full route is twenty miles and it takes about an hour to go from London Bridge station to Palmers Green.
- The route is currently run by older Wrightbus hybrid diesel-electric buses.
- I suspect that modern hydrogen buses could last almost all day on one fill of hydrogen, with perhaps a top-up at lunchtime.
They would have no difficulty handling the route and would greatly increase the customers current rock-bottom satisfaction.
I am sure, they would improve the horrendous reliability of the route.
I also wonder, if Wrightbus have another solution.
In UK Among Tri-Axle Zero-Emission Wrightbus StreetDeck Prospects, I talk about Wrightbus’s new Tri-Axle Zero-Emission Wrightbus StreetDeck bus and how it would be ideal for the 141 bus route.
- The 141 bus route is the old 641 trolleybus route, so all clearances are generous.
- The tri-axle design can probably carry a better-optimised battery.
- There used to be two bus routes on the route and now there is only one, so more capacity is needed.
- The 141 bus route bridges the gap between the Northern section of the Piccadilly Line and the Elizabeth Line, Bank and London Bridge.
- The new air-conditioned Piccadilly Line trains, will increase the passengers on the line.
- There will be a lot more housing built in Enfield, at the Northern end of the Piccadilly Line and more bus capacity will be needed between Manor House and the City of London.
Some of TfL’s rerouting of buses in North London, was a crime against mathematics.
E.ON Invests £4 million In Allume Energy To Boost Solar Rollout For Flats
The title of this post, is the same as that of this article on Solar Power Portal.
These three paragraphs explain the deal and say a small amount about Alume’s SolShare system.
Energy supplier E.ON UK has today (17 June) announced that it has signed a strategic investment agreement with Australian firm Allume Energy to help the firm expand into the UK.
E.ON UK has invested £4 million into Allume Energy to enable Allume to expand the reach of its SolShare technology within the UK market. SolShare allows solar energy from a single rooftop solar PV installation to be fairly shared amongst multiple homes in the same building in order to allow residents of flats to access solar PV energy.
Residents are supplied their energy when they are using by a pre-determined allocation, allowing them to lower their energy bills. Many blocks of flats that do have solar panels fitted currently only use this energy to power the common areas of the building while residents still pay their full electricity bill. According to Allume, a shared rooftop solar PV system can reduce resident energy bills by between 30% and 60%.
I must say, that when I read this article, it had something of the too-good-to-be-true about it.
But.
- My solar installation on a fair-sized roof cost me about £6,000 and I am constantly surprised at how much electricity it provides.
- If you have fifty flats, they all won’t do their weekly washing at the same time each week.
- I wouldn’t be surprised to see a big battery somewhere or a small battery in each flat.
- The batteries could soak up any excess electricity or charge on cheap-rate overnight electricity.
- Do Allume’s engineers go through every flat and make suggestions about saving energy?
- Is the pattern of electricity usage in a block of flats predictable from past usage and factors like weather, the time of the year and what’s on television?
- I wouldn’t be surprised that Allume have performed extensive mathematical modelling on blocks of flats.
I think this deal could be a winner foe E.ON, Allume and their customers.
I have some ideas about the use of the system.
Would It Work On A Small Housing Estate?
A small housing estate would be a number of solar roofs feeding a number of houses, whereas with flats it will be one roof feeding a number of dwellings.
I suspect that with a well-designed sharing and pooling system, a lot of features of the flat-powering system could be used to power houses.
How Does The System Handle Electric Vehicles?
The system could use these to store electricity, so that they are always charged at the cheapest rate.
And when there is a shortage of electricity, the electricity could be borrowed by the Allume system.
Conclusion
If you have community sharing their own source of electricity, you can probably make ideas work, that wouldn’t in a single application.
My nose says Allume’s idea has legs.
Could The Silvertown Tunnel Handle More Buses?
In A Return Journey Through The Silvertown Tunnel On A 129 Bus, I took these pictures inside the Silvertown Tunnel when the bus was coming North.
Note.
- The left lane is marked Bus Lane.
- Only one car is visible in the right lane.
- The tunnel seems well-lit.
I have some thoughts
Where’s The Traffic?
It does appear that two apparently empty lanes in each direction, don’t carry a large number of vehicles.
- Have the tolls and arguments frightened traffic away?
- Are the tolls too high?
- From the full set of pictures in the linked post, it would appear more vehicles were using the Blackwall Tunnel.
- Could it be that drivers are frightened of getting a speeding ticket?
- Are drivers frightened of sharing the tunnel with buses and heavy trucks?
Both bores of the Silvertown Tunnel seem to have similar traffic levels.
What’s The Capacity Of A Bus Lane?
In the Wikipedia entry for bus lane, this is said.
The busiest bus lane in the United States is the Lincoln Tunnel XBL (exclusive bus lane) along the Lincoln Tunnel Approach and Helix in Hudson County, New Jersey, which carries approximately 700 buses per hour during morning peak times an average of one bus every 5.1 seconds.[ In contrast, the Cross-Harbour Tunnel in Hong Kong carries 14,500 buses per day, or an average of about 605 an hour all day (not just peak times), but the bus lane must give way to all the other road users resulting in long queues of buses.
Perhaps a more realistic example of tunnel capacity from the UK, would be the Victoria Line, which handles thirty-six * eight-car trains per hour (tph) in both directions in two tunnels.
I would certainly expect that if Dear Old Vicky can manage 36 x 8-car trains per hour, then the Silvertown tunnel could handle thirty-six buses per hour.
Especially, if the buses had a distance keeping capability, as many trains do.
How Many Buses Per Hour Are Planned to Use The Silvertown And Blackwall Tunnels?
This handy map from Transport for London, shows the three bus routes passing through the Silvertown and Blackwall Tunnels.
Click the map to show it to a larger scale.
The map gives these frequencies for the three bus routes using the tunnels.
Bus Route SL4
Operates once every 8 minutes or at seven buses per hour.
Bus Route 108
Operates once every 10 minutes or at six buses per hour.
Bus Route 129
Operates once every 8 minutes or at seven buses per hour.
Silvertown Tunnel Bicycle Shuttle
Google AI says this.
The Silvertown Tunnel cycle shuttle bus runs approximately every 12 minutes, operating daily from 6:30 am to 9:30 pm, except for Christmas Day, offering a safe and quick way for cyclists to cross the Thames.
This operates at five buses per hour.
Number Of Buses Through The Tunnels
There will be around nineteen buses per hour, through the Silvertown Tunnel and six through the Blackwall.
The Silvertown Tunnel looks like it has been designed to accept more buses.
One thing this means, is that if the Blackwall gets shut, then the 108 can use some of the spare capacity in the Silvertown Tunnel.
Could A Coach Station For Europe Use Some Of The Spare Capacity?
In Development To The West Of The North Entrance Of The Silvertown Tunnel, I displayed this.
This Google Map shows the site to the West of the North entrance of the Silvertown Tunnel.
Note.
- The red arrow indicates City Hall.
- There is a large site between the DLR and the river.
- The Docklands Light Railway separates the site from the North entrance of the Silvertown Tunnel.
- The CEMEX Thames Aggregate Wharf seems to occupy part of the site.
This picture shows the North entrance of the Silvertown Tunnel from the cable-car.
It is surely a site with development potential, as Roy Brooks would say.
It will probably be used for more tower blocks along the Thames.
But could it be used for a coach station to handle the increasing number of coaches between London and the Continent?
- A Docklands Light Railway station could be built to serve the site.
- Thames Clippers could also serve the site.
- Coaches could use the Silvertown Tunnel to start their journey out of the capital.
It is certainly a possibility.
Could The Silvertown Tunnel Be Used For Route-Proving For The Docklands Light Railway?
In TfL Considering Extending DLR As Far As Abbey Wood, I discussed extending the Docklands Light Railway to Thamesmead or Abbey Wood.
This map from Ian Visits shows the area.
Running a four buses per hour service through the Silvertown Tunnel, would be an ideal way of proving what is the best route.
Extending The Docklands Light Railway To The West
No matter how the Docklands Railway is extended to the East, either by physical means like extra branches or by virtual means like connecting to bus routes, this will mean that there will need to be more terminal capacity in the West, to take the pressure off Bank and Tower Gateway stations.
In A Connection Between City Thameslink Station And The Docklands Light Railway, I described a proposal to extend the Docklands Light Railway to Euston, St. Pancras and Victoria.
In the Wikipedia entry for the Docklands Light Railway, there is a section describing a proposed Euston/St. Pancras Extension.
This is said.
In 2011, strategy documents proposed a DLR extension to Euston and St Pancras. Transport for London have considered driving a line from City Thameslink via Holborn north to the rail termini. The main benefit of such an extension would be to broaden the available direct transport links to the Canary Wharf site. It would create a new artery in central London and help relieve the Northern and Circle lines and provide another metro line to serve the High Speed line into Euston.
This map from Transport for London, shows the possible Western extension of the DLR.
With all the problems of the funding of Crossrail 2, that I wrote about in Crossrail 2 Review Prompts Fresh Delays, could this extension of the DLR, be a good idea?
Consider.
- Victoria, Euston and St. Pancras are prosposed Crossrail 2 stations.
- It would link Canary Wharf and the City of London to Eurostar, Northern and Scottish services and High Speed Two.
- It would give all of the Docklands Light Railway network access to Thameslink.
- A pair of well-designed termini at Euston and St. Pancras would probably increase frequency and capacity on the Bank branch of the system.
- The DLR is getting new higher capacity trains.
- Bank station is being upgraded with forty percent more passenger capacity.
- Holborn station is being upgraded and hopefully will be future-proofed for this extension.
- One big advantage at City Thameslink, is that Thameslink and the proposed DLR extension will cross at right-angles, thus probably making designing a good step-free interchange easier.
- The Bank Branch of the DLR currently handles 15 tph, but could probably handle more, if they went on to two terminal stations at St Pancras and Victoria..
- Waterloo and City Line can run at twenty-four tph.
Cinderella she may be, but then she always delivers, when there is a desperate need, just as she did magnificently at the 2012 Olympics.
Something is needed to handle the extra passengers at Euston, that will be brought to London by High Speed Two. Cinderella is the only way to deliver a connection in a reasonable time.
The only problem with this extension of the DLR, is that compared to the rest of the system, the views will be terrible.
For myself and all the others living along the East London Line, with a step-free change at Shadwell, we would get excellent access to Euston, St. Pancras and Victoria.
But could the line still be called the Docklands Light Railway, as it spreads its tentacles further?
Development To The West Of The North Entrance Of The Silvertown Tunnel
This Google Map shows the site to the West of the North entrance of the Silvertown Tunnel.
Note.
- The red arrow indicates City Hall.
- There is a large site between the DLR and the river.
- The Docklands Light Railway separates the site from the North entrance of the Silvertown Tunnel.
- The CEMEX Thames Aggregate Wharf seems to occupy part of the site.
This picture shows the North entrance of the Silvertown Tunnel from the cable-car.
It is surely a site with development potential, as Roy Brooks would say.
It will probably be used for more tower blocks along the Thames.
But could it be used for a coach station to handle the increasing number of coaches between London and the Continent?
- A Docklands Light Railway station could be built to serve the site.
- Thames Clippers could also serve the site.
- Coaches could use the Silvertown Tunnel to start their journey out of the capital.
I added these pictures, that were taken of the site from the Docklands Light Railway, a day later.
The site certainly has development potential.
From Doncaster To Cleethorpes
These pictures were taken on my journey between Doncaster and Cleethorpes.
The area is best summed up as flat and decorated with these features.
- A few hedges.
- Some trees and some woodland.
- dozens of wind turbines.
- Lots of pylons carrying electricity.
- Scunthorpe steelworks
- A few stations and railway sidings.
- A couple of waterways.
- Estates of new housing as you approach Grimsby.
When I returned there was more of the same on the other side of the tracks.
With the addition of all the power stations at Keadby and a couple of wind farms.
These are my thoughts on how this landscape will look at some time after 2030.
More Onshore Wind Farms
There will be a lot more wind farms lining the Doncaster and Cleethorpes railway.
The government has said it might pay for turbines and transmission lines to spoil views.
I feel they will have to, to meet their net-zero targets.
There Will Be Massive Hydrogen Storage On The Other Side Of The Humber
SSE are developing Albrough and Centrica are developing Rough into two of the largest hydrogen stores in the world.
The wind farms of the North Sea will provide them with hydrogen.
More Housing
If the government has its wish there will be a lot more new housing.
And as the newer houses show in my pictures, many of them will have solar panels.
More Power Stations At Keadby
Consider.
- The main purpose of the power stations at Keadby will be to provide backup to the wind and solar power in the area and far out to sea.
- The power stations will use hydrogen stored at Albrough and Rough.
- Some of the gas-fired power stations at Keadby will be fitted with carbon capture.
- One hydrogen-fired power station is already being planned.
The power stations at Keadby will probably be capable of supplying several GW of zero-carbon energy.
There Will Be Energy-Hungry Industries Along The South Bank Of The Humber
Just as in the Victorian era, coal attracted steel-making, chemicals and refining to the area, a South Humberside with large amounts of energy will attract heavy industry again.
Already, Siemens have built a train factory at Goole.
There Will Also Be Large Greenhouses In Lincolnshire
Greenhouses are a wonderful green way of absorbing waste heat and carbon dioxide.
Where Have I Seen This Blend Of Offshore Energy, Hydrogen, Heavy Industry And Agriculture Before?
After I visited Eemshaven in the Northern Netherlands, I wrote The Dutch Plan For Hydrogen.
We are not doing something similar, but something much bigger, based on the hydrogen stores at Aldbrough and Brough, the massive offshore wind farms and Lincolnshire’s traditional heavy industry and agriculture.
The Railway Between Doncaster and Cleethorpes Will Be Developed
Just as the Dutch have developed the railways between Groningen and Eemshaven.
Stowmarket Station – 14th March 2025
tThe one and only time, that I’ve used Stowmarket station, was when I’d taken my Lotus in for a service near Diss and I was getting back to Newmarket, with a change at the station.
So as I was going to Stowmarket station, I felt with the judicious use of a East Anglian Ranger ticket, I could combine the trips to Stowmarket and Saxmundham stations.
I also wanted to look at the progress on the new footbridge that I wrote about in Stowmarket Station To Go Step-Free.
I took these pictures.
Note.
- I arrived on the Norwich-bound platform, crossed the tracks by the level crossing and then left from the Ipswich-bound platform.
- The station has a cafe.
- The footbridge in the pictures is a temporary one to ease construction.
- The station buildings are Grade II Listed.
There doesn’t appear to have been much progress on the new footbridge.
I do have some other thoughts.
Greater Anglia’s Stadler Trains Are Step-Free Between Train And Platform
The first two and last pictures in the gallery show this feature.
I arrived on a Class 745 train and left on a Class 755 and both train classes have gap fillers, that do their job automatically.
We need more of this technology to protect the elderly, those with restricted movement and the just untrained stupid.
Housing By The Station
It appears that two blocks of flats have been built on railway land or the station car park.
The bridge also appears to give the owners and residents access across the railway.
Is this thoughtful holistic design or just a bribe to get planning permission?
Who Will Use The Footbridge?
Two main lines effectively cross at Stowmarket.
- The Great Eastern Main Line between Ipswich and Norwich goes through Needham Market, Stowmarket and Diss.
- The Ipswich and Ely Line between Ipswich and Cambridge goes through Needham Market, Stowmarket, Elmswell, Thurston, Bury St. Edmunds, Kennett, Newmarket and Dullingham.
So, if you need to go between say Newmarket and Diss, you would change trains at Stowmarket. Hopefully, the bridge will encourage train travel.
New Housing In East Anglia
On the main railway lines between Cambridge, Ipswich and Norwich, there used to be a lot more stations.
- There are eight closed stations between Stowmarket and Cambridge.
- There are three closed stations between Stowmarket and Ely .
- There are two closed stations between Stowmarket and Ipswich.
- There are eight closed stations between Stowmarket and Norwich.
Note.
- A new Soham station was built between Stowmarket and Ely. Passenger numbers are rising with each year.
- I have double-counted Higham and Saxham and Risby stations on both the Ely and Cambridge routes.
- But that still leaves nineteen stations, that might be good sites to build new houses.
- The East-West Railway intend to build a new A14 Parkway station to link the A14 road to the Ipswich and Ely Line.
- When housing is taken into account, some stations will give a better return on investment.
Could the new footbridge at Stowmarket be part of a wide ranging plan to build more housing in towns and villages along the railways of East Anglia?
Was The Old Footbridge Too Low?
This picture was taken of the old bridge.
Was the bridge too low for some container trains?
Colindale Tube Station – 26th December 2024
Colindale station opened on Friday, so I went to have a look.
Note.
- Although not finished, it certainly works safely as a station.
- Currently, there is a one way system for passengers.
- It appears a lift is being installed.
- The lift shaft appears to be labelled as Cornish Concrete Products.
- Wikipedia reports that two large towers with 300 new homes will also be built directly adjacent to the new station building.
- There are no ticket barriers.
- On the platforms, there are no information screens! But maps are present.
How many other of London’s Underground stations need a rebuild to bring them up to a modern standard with respect to disabled access?
Housing Over Railway Stations
With a shortage of housing in the UK, should we be building more housing like this?
- Apartments over a step-free railway station.
- Shops and cafes at the ground level.
- Buses and taxis for local transport.
- Green space – There is a park opposite the station.
- Parking as needed.
As a non-driver, an apartment like this might just do for me!
But not in Colindale!
House Sitting With Ocado
I like animals and I miss having cats, dogs and horses around.
I particularly miss our stallion ; Vague Shot, who had a nickname of Cyril. When I was feeling down, he always had time for a chat and a cuddle.
It may seem strange, but when C died, Cyril was the first I told. But then as he was a stallion, the stud was his personal domain. Hence his understanding.
Recently, I’ve taken to doing my shopping at Ocado, which means that my coeliac disease, is not a problem, if Ocado deliver.
I had thought about house and pet sitting before, but my coeliac disease and the fact I don’t drive seemed to end discussions.
So I think, I’m going to do a bit of house and small pet sitting, mainly to get a welcome change of scenery. I’ll leave the logistics to Ocado.
Consider.
- I have no pets myself.
- I am a non-smoker.
- I am more or less tee-total these days.
- I have no children or grandchildren under 23.
- I will tell Ocado, as I have no connection with them, except as a customer, who uses their services regularly.
