Zero-Carbon Lighting Of Large Spaces
In Cockfosters Train Depot – 12th January 2023, I took a series of pictures of Cockfosters Train Depot, of which these are a selection.
Note, the lamp clusters on top of tall poles to light the area.
You see lots of these lights to illuminate play areas, car parks, rail sidings and truck depots.
Could a SeaTwirl or another vertical wind turbine be placed as high as possible up the pole, that supports the lights?
- A battery would be needed for when the wind doesn’t blow.
- A control system would be used to use the lights, when they are needed.
- The poles would be able to be laid down, like many lights can be, for servicing from the ground.
Cockfosters would be an excellent location for a test, as the wind is always blowing and the site has an altitude of nearly a hundred metres.
Would A Solar Roof With Added SeaTwirls Work?
This picture shows Oakwood station on the Piccadilly Line.
Note.
- The station is the second most Northerly on the line.
- It opened in 1933.
- It is a classic Charles Holden design.
- It is a Grade II* Listed building.
- The station is on top of a hill and has an elevation of 71 metres above sea level.
This Google Map shows a close-up of the roof.
There might be a few aerials on the roof, but no solar panels.
Oakwood’s Location And Weather
I used to live near Oakwood station and it had its disadvantages.
- Cycling home was always up a steep hill.
- It could get very cold at times.
There even used to be a plaque at the station, which said that if you flew East, the first land you would hit would be the Urals.
Oakwood station could be an ideal renewable power station.
- The concrete and brick box of the station is probably exceedingly strong.
- Solar panels could cover the flat roof.
- SeaTwirls or other vertical turbines could be mounted around the solar panels.
- There could still be spaces for the aerials.
- I wonder what the reaction of English Heritage would be.
Should we call this mixed solar and wind power generation, hybrid renewable energy? Or do we overdo, the use of hybrid?
London Underground have other stations of a similar design including Sudbury Town and Acton Town.
The Wider Area To The West Of Oakwood Station
This Google Map shows the area to the West of Oakwood station.
Note.
- The striped roofs at the top of the map, with sidings for trains to the North, is Cockfosters Train Depot for the Piccadilly Line..
- The large building in the South-West corner is Southgate School, which I watched being built in the early 1960s, from my bedroom window in our house opposite. It is a concrete frame building typical of the period.
- Oakwood station is at the East side of the map and indicated by a London Underground roundel.
I think the possibilities for hybrid power generation in this area are good.
Cockfosters Depot
Cockfosters Depot could be an interesting site to develop as a renewable power station.
- There’s no way the site could be developed for housing, as it’s in the Green Belt.
- Road access is bad, but access for trains is good.
- I estimate that the depot is an area of at least five square kilometres.
- It’s still windy in the depot.
But it could have a solar roof and a few vertical wind turbines over the whole depot as designs and panels improve.
Southgate School
Southgate School could have a similar setup to Oakwood station.
Opportunities At Cockfosters Station
This Google Map shows a 3D image of Cockfosters station and the buildings around it.
Note.
- Cockfosters station is indicated by the roundel.
- The station is a Grade II Listed building.
- The station has an elevation of 97 metres.
- Half of the station car park is going to be turned into housing.
- Trent Park lies to the North of the station.
- The road in front of the station is Cockfosters Road, which to the North joins the M25 at Junction 24.
- The building between Cockfosters Road and the railway used to be offices, but it is now being converted into housing.
That high roof of the housing development, must be an ideal candidate for solar panels and vertical wind turbines.
Conclusion
I have tried to show the potential of just one of the small hills that ring London.
The Ultimate Bus Stop
London has very comprehensive bus stops as these pictures show.
Note.
- Most bus stops have a pole mounted roundel, that can be seen from a reasonable distance. In many cases, anybody with reasonable sight can see the roundel for the next stop.
- Where space permits, bus stops have a shelter with seats, maps and instructions on ticketing.
- Some stops have been extended into the road, so that it is a level step into and out of the bus.
- As shown in the pictures, so bus stops have displays showing the next ten buses, that will be arriving.
But I do think, they could be improved, with extra features.
Internet Connectivity
I feel strongly, that all bus stops should have good internet connectivity.
This could be 4G, 5G or just wi-fi, but I believe this could help with the safety of people on the street.
Comprehensive Lighting
To contribute to safety, I also feel that all bus stops should be well lit.
CCTV Issues
I also feel that all bus stops should have provision for CCTV, so if there was a need, it could be quickly fitted. But if the bus stop had good internet connectivity, then this shouldn’t be a problem.
Phone Charging
New buses have this feature, so why not at the stops?
Power Supply Issues
If we add all these features, we could be needed an uprated power supply.
- So could we see bus stops, with solar panels on the roof.
- Perhaps even a mini wind turbine?
- I think a vertical wind turbine, which was similar to a SeaTwirl, but smaller, could be ideal!
- Could it be called a StreeTwirl?
- A self-powered bus could be created with the addition of a battery.
Self-powered bus stops might be easier to install.
Conclusion
Bus stops will have more features in the future.
Another Renewable Power Idea From Sweden
I have posted some ideas from Sweden on this blog including.
- H2 Green Steel – H2 Green Steel Plans 800 MW Hydrogen Plant In Sweden
- HYBRIT – Sweden’s Grand Plan To Make Zero-Carbon Steel
- Minesto – Is This The World’s Best Renewable Energy Video?
- TwinHub – Hexicon Wins UK’s First Ever CfD Auction For Floating Offshore Wind
And now there’s the SEATWIRL, which the company says is the future of offshore wind.
In the Areas Of Use, there is a section with a heading of SeaTwirl For Niche Markets, where this is said.
SeaTwirl has now identified markets where wind turbines of the size of 1 MW can meet a clear market demand and sees a possibility to build a business aimed at these niche markets in parallel with its main target. That can mean revenues for the company sooner than was originally planned.
The niche markets that have been identified are islands and remote seaside villages, fish farms and desalination plants. These are business and places that today are run mainly on electricity from diesel generators, which is both expensive and emits CO2.
One of the places I would use these turbines, is on the apex of four-beam steel portal frame buildings. The original concept for these buildings had been developed at Cambridge University during World War Two and one of the team, had set up a business in Warwickshire, constructing these buildings for barns, factory units and other purposes.
He had programmed a simple computer program, which he ran on a time-shared computer system. I was hired to improve the computer program.
What surprised me was the strength of these buildings and I believe they could support vertical turbines like SeaTwirl along the apex.
I feel there are many other applications, especially if they are designed to be part pf a bigger system.
Conclusion
I like the concept of SeaTwirl.
