Justice – Texas Style
I can’t work out whether this story on NBC, which is entitled Texas Taqueria Customer Fatally Shoots Masked Robber And Returns Money To Patrons, Police Say, makes me feel carrying guns is a good or bad idea?
But at least he seems to know how to use his weapon, as he only hit one person; the robber.
Norwegian Companies To Explore Using Aluminium In Floating Offshore Wind Turbines
This is based on this press release from World Wide Wind, which is entitled WORLD WIDE WIND AS and HYDRO ASA Signs Letter Of Intent Aiming At Using Aluminium In Offshore Floating Wind Turbines.
This is the first paragraph.
Hydro, the world leading Norwegian aluminium and energy company and World Wide Wind AS, a Norwegian company developing a floating wind turbine, have signed a Letter of Intent (LoI) to explore the use of aluminium in the renewable wind industry. The two Norwegian companies are partnering up to develop floating wind turbines with a design specifically meant for offshore conditions. The goal is to use sustainable and recyclable materials in the construction, including aluminium.
In Do All Wind Turbines Have To Be Similar?, I said this about the radically different turbines of World Wide Wind.
I’ll let the images on the World Wide Wind web site do the talking.
But who would have thought, that contrarotating wind turbines, set at an angle in the sea would work?
This is so unusual, it might just work very well.
As aluminium is lighter, it might be a factor in the success of the design.
This is the last paragraph of the press release.
World Wide Wind’s integrated floating wind turbines are scalable up to 40MW – 2,5 times current wind turbines – and will use less materials and have a smaller CO2 footprint than conventional turbines. It is World Wide Wind’s ambition that these turbines will represent future design for floating wind turbine design.
40 MW is a very large turbine. This is definitely a case of handsome is as handsome does!
How Liquid Air Could Solve The UK’s Energy Conundrum
The title of this post, is the same as that of this article on The Telegraph.
The article is mainly an article that described the technology and it discloses a few facts.
- The Carrington plant should be delivered in 2024.
- Carrington will be a 30 MW/30 MWh system.
- Efficiency is around 50 %, but there are possibilities to raise it to 70 %.
- Australia is mentioned as a market.
- It is likely to be paired with supercapacitors or a flywheel to have a quick start.
- It seems to me, that turning an idea into a practical system is taking a lot of work and money, and a bit of a rethink.
But hopefully, the system will eventually be developed, as it does promise to be an energy storage system, that doesn’t make high demands on the environment in terms of expensive metals and rare earths.
NHS To Buy Up Care Beds To Clear Wards
The title of this post, is the same as that of this article on the Sunday Times.
I can remember, when my late wife had her appendix out in 1967 in Barnet General Hospital, that there were two bed-blockers on the ward, where she was being treated. One had serious dementia.Has it really taken nearly sixty years to sort out this problem?
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.
Should There Be Limits To The Type Of Vehicles Allowed In The Blackwall And Silvertown Tunnels?
When the Silvertown Tunnel opens in 2025, the tunnel and the nearby Blackwall Tunnel will be tolled.
But will there be any restrictions on the vehicles that can use the tunnels, other than those that apply to the Blackwall Tunnel at the present time, which are detailed in Wikipedia.
The tunnels are no longer open to pedestrians, cyclists or other non-motorised traffic, and the northbound tunnel has a 4.0-metre (13.1 ft) height limit.
Note.
- I suspect that pedestrians, cyclists or other non-motorised traffic will also be banned from the Silverton Tunnel.
- But the height limit will be relaxed for the Silverton Tunnel to allow large trucks and double-deck buses to use the tunnel.
According to this web page, which is entitled the Silvertown Tunnel Bus Network Proposals, the planned buses through the tunnel include.
- 108 – As now, with a minor route change.
- 129 – As now, but extended from North Greenwich station to Great Eastern Quay.
- X329 – An express bus from Grove Park station to Canary Wharf, which runs non-stop through the Silvertown Tunnel.
Note.
- The 108 goes through Blackwall and is a single decker bus.
- The 129 and the X329 will go through Silvertown and could be double decker buses.
- There appears to be no mention of any provision for cycles.
- I would assume wheelchairs, buggies and cases will be accommodated as they are on current London buses.
I also think, that the buses must be zero-carbon, which would mean battery-electric or hydrogen.
In Hydrogen-Powered Vehicles And Trains In Tunnels, I looked at the feasibility of running hydrogen buses through the tunnel and came to this conclusion.
I am confident, that we will achieve a safety regime, that allows hydrogen-powered vehicles and trains to be certified to pass through tunnels.
The great advantage of hydrogen buses on the three routes would be that they would probably only need to be filled up once a day, but electric buses might need constant charging.
Provision For Cycles
I think it is essential to have provision for cycles across the river.
- Folded cycles can be taken almost anywhere on London’s transport system.
- Non-folding cycles can be taken most places on London’s transport system, but the hours are restricted.
- There’s always the Woolwich Ferry.
- Given that the 108 bus seems to weave its way through the East End, I suspect that this bus couldn’t be longer to carry cycles.
I have seen double-deck buses, with provision for cycles at the back of the lower deck in Europe.
- Perhaps buses like these, could be used on the 129 and X329 routes.
- A search of the Internet found some buses in East Yorkshire with provision for two standard cycles.
- The 129 bus could ferry bikes between North Greenwich station and a convenient stop on the North side of the river.
- The X329 bus could ferry bikes over the non-stop section of the route between the Sun in the Sands and Leamouth roundabouts.
There could be shorter routes adding extra capacity between the stops, where bikes are loaded and unloaded.
Large Trucks Through The Tunnel
If buses become zero-carbon through the Blackwall and Silverton Tunnels, then why shouldn’t large trucks be zero-carbon?
I think this could be the carrot combined with free passage for zero-carbon vehicles that could clean up Central London’s polluted air.
Smaller Vehicles
Why not gradually reduce the size of vehicles going through the tunnels that must be zero-carbon?
Conclusion
The Silvertown and Blackwall Tunnels can be used as the drivers to clean up Central London’s air.
Hydrogen-Powered Vehicles And Trains In Tunnels
In writing about the Silvertown Tunnel, I started to wonder, if hydrogen vehicles will be allowed in the tunnel.
Consider.
- I don’t think diesel-powered trains are allowed in the Channel Tunnel and the tunnels of the link to London.
- Some tunnels don’t seem to allow hydrogen-powered vehicles.
- In a few years, hydrogen-powered buses, cars, locomotives, trains, trucks and vans will be more common, than they are today.
But help is at hand, with a co-operation between UK and EU agencies called HyTunnel-CS.
It is over fifty years now, since I worked as an instrument engineer in an ICI hydrogen factory at Runcorn. Truckloads of hydrogen were filled and despatched all over the UK. I may be wrong, but in all those intervening years, I can’t remember a hydrogen emergency on the UK’s roads.
I am confident, that we will achieve a safety regime, that allows hydrogen-powered vehicles and trains to be certified to pass through tunnels.
Silvertown Tunnel Bus Network Proposals
This web page is the Silvertown Tunnel Bus Network Proposals.
These proposals are made.
- A new high frequency, limited stop service between Grove Park and Canary Wharf referred to in this consultation as route X239
- To extend route 129 (Lewisham – North Greenwich) north across the river to Great Eastern Quay via the Royal Docks development zone
- A minor change to route 108 so that it uses the new Millennium Way slip road to exit the Blackwall Tunnel southbound
- We are also seeking your views on route options for three sections of routes 129 and X239.
It looks like route 108 will continue to use the current stop.
The proposals include this map.
I copied this map from the TfL web site, as they don’t provide one for people who want or need to use it.
These are my observations.
The 108 Bus
The 108 seems to be more or less as now and will be continue to be run by a single-decker bus, as double-decker buses can’t use the Blackwall Tunnel.
North of the Thames, the 108 calls at these stations.
- Stratford International for DLR and National Rail.
- Stratford for DLR, Central, Elizabeth and Jubilee Lines, and National Rail.
- Bow Church for DLR
- Devons Road for DLR
- Langdon Park for the DLR
- Bazely Street (All Saints) for DLR
South of the Thames, the 108 calls at these stations.
- North Greenwich for the Jubilee Line.
- Westcombe Park for National Rail
- Blackheath for National Rail
- Lewisham for DLR and National Rail
Note.
- It is possible to go between Lewisham and Stratford on the DLR with a change at Canary Wharf.
- It is possible to go between North Greenwich and Stratford on the Jubilee Line.
- Westcombe Park station is on the Greenwich Line.
I would wonder, if many people use this bus route for long distances.
The 129 Bus
Note.
- The 129 appears to connect Lewisham and Greenwich to the City Airport and the Becton branch of the DLR.
- Many journeys on the 129 bus, might be easier using the DLR, with a change at Westferry or Poplar, which is probably what travellers do now.
- The 129 bus is shown on the map with a stop at Silvertown. Does that mean that it could connect with a Silvertown station on the Elizabeth Line?
- As the 129 bus will pass through the larger Silvertown Tunnel, it could be a double-decker route, instead of the current single-decker.
North of the Thames, the 129 calls at these stations.
- Gallions Reach for the DLR
- Beckton for the DLR
- Royal Albert for the DLR
- London City Airport for the DLR
- Silvertown
- Pontoon Dock for the DLR
- West Silvertown for the DLR
South of the Thames, the 129 calls at these stations.
- North Greenwich for the Jubilee Line.
- Cutty Sark for DLR
- Greenwich for DLR and National Rail
- Lewisham for DLR and National Rail
Would improvements and a frequency increase to the DLR and the building of Silvertown station, mean that changes to the 129 bus route, would not be so important?
The X329 Bus
Note.
- Canary Wharf must be served and starting at Westferry Circus is probably a good choice.
- But is Grove Park station, the ideal Southern terminal?
- Not stopping the X329 bus at North Greenwich is probably correct, as North Greenwich station is a large Jubilee Line and bus interchange close to the O2.
North of the Thames, the X329 calls at these stations.
- Canary Wharf for DLR and Elizabeth and Jubilee Lines
South of the Thames, the X329 calls at these stations.
- Blackheath for National Rail
- Lee for National Rail
- Grove Park for National Rail
Note.
- Blackheath station is on the Bexleyheath and North Kent Lines.
- Lee station is on the Dartford Loop Line.
- Grove Park station is on the South Eastern Man Line.
- Grove Park has a bus station, where there could be space for a battery charger for electric buses.
The X329 seems to have been partly designed on the premise, that an express bus should be run through the Silvertown Tunnel. But it does connect four of the rail lines going into London terminals to Canary Wharf.
Silvertown Station For London City Airport
Silvertown station would more than double the number of stations with easy routes to the London City Airport.
The Elizabeth Line would enable the direct connection that is needed to Canary Wharf, the City of London, Heathrow, Liverpool Street and Paddington stations and the West End.
- A single change at Abbey Wood, would give access to much of Kent.
- A single change at Farringdon, would give access to Thameslink services and Gatwick and Luton airports.
- Around 2030, a single change at Old Oak Common, would give access to High Speed Two services.
- A single change at Paddington, would give access to Wales and West services.
- A single change at Whitechapel, would give access to the great circle of the London Overground.
I believe the case for a Silvertown station with at least a good walking route to the London City Airport is strong, and the station would be a marvellous asset for Silvertown and the Airport.
The Northern End Of The Silvertown Tunnel From The DLR To Woolwich Arsenal – 6th January 2023
I took these pictures of the Northern end of the Silvertown Tunnel from DLR trains to and from Woolwich Arsenal.
Note.
- The New London City Hall and the Cable Car in the background.
- All pictures were taken going to Woolwich.
The pictures are better than the earlier ones, which I may retire.
