TODMORDEN IN BLOOM

The guest speaker at the u3a Todmorden Members Meeting on the 21st of May 2026 was Adrian Nixon, who presented ‘Space Elevators - A Stairway to the Heavens.
In his introduction, Adrian referred to the table full of objects on display and said that the subject and project was unknown to most people – but found that several members classified themselves as scientists or engineer, which was more than most of audiences who have attended his talks.

He has two jobs; one is for the International Space Expedition Consortium, which is based in California, which anyone can join via the internet. The second is being on the board of that organisation. He took us through the details of his colleagues including ex astronauts, engineers, physicists, and people who work in Artificial Intelligence.

Adrian introduced us to Graphene - which is the vital part of the project, with a slide showing a pencil. Most, if not all, of the audience knew that the ‘lead’ of a pencil is called Graphite. One of the chemical elements that make up Graphite is Graphene. During the 20th century, physicists argued convincingly that materials like Graphene would be too thermodynamically unstable to exist. So, nobody tried to isolate it. It was likened to a small layer of water on a surface which would come apart eventually.
But, in 2004, Graphene was isolated as world’s first 2 dimensional material using sticky tape, and 2010 scientists Andre Geim and Konstantin Novoselov won a Nobel Prize for preparing and characterizing the element. Up to then, most scientists accepted the view that Graphene was impossible to isolate from Graphite. For years, researchers had been using sticky tape to prepare Graphite samples for electron microscopy work. Adrian showed a slide of Graphene, which is a two-dimensional form of carbon. He pointed out, using a slide, that the element resembles a sort of chicken wire. Another slide showed ten characteristics of Graphene including :

SPACE ELEVATOR-A STAIRWAY TO THE HEAVENS

Graphene is currently manufactured as powders, and some applications are starting to evolve sheet or film Graphene, which is a far higher market value. Defect free sheet Graphene is the ideal and is called Single Crystal Graphene which has a far higher market value.
Products already containing Graphene include Ford Cars – over five million by now which, amongst other features, could make car bumpers around 40% better at absorbing impacts. It has been quoted as 'somewhere between carbon fibre and metal'. The tyres of some cars which are driven in long distance races contain Graphene extends to various components of the tyre, including sidewalls and tread compounds, a solution to degradation challenges and vehicle range.
Adrian gave us another example, using some audience participation by asking what, eventually, happens to Helium balloons? The fabric of the balloons is not strong enough, after time, to hold the Helium inside. One atomic layer of Graphene is the same as a two-kilometre-thick wall of glass and the helium would never escape. Graphene has a melting point of five and half thousand degrees centigrade and could sit on the sun.
With other examples of the characteristics of Graphene, he said that it is, or could be an equivalent of a ‘super hero’. He mentioned a current trial on the A1 where the asphalt on a part of the road has been taken up and ‘remixed’ to contain Graphene, then re-used. If successful it may lead to less roadworks and, who knows? repair of potholes.
Worldwide, from 2020 to 2024, one point three billion dollars has been invested in Graphene applications which include $249million enhanced Li-ion batteries to be faster charging and non-flammable plus, along with other projects, $10 million on Graphene enhanced concrete, making it 30% stronger.
Another project was to coat the sides of ships with Graphene, which would reduce barnacles growing on the sides of them. At the moment there are 600 ships with this treatment, and results show a reduction of 4% of fuel costs helping worldwide CO2 reduction.
Adrian moved the presentation along to tell us more about the ‘Elevator’ mentioned in the title of his talk. He told us that anything other than the fuel currently needed to get rockets to the current space station and back, accounts for all but 4% of its weight. With a rocket to reach the moon, all but half a percent is used on getting there and back.
Rockets have limitations. They are good for lifting people but have limited capacity. 4% of launch pad mass gets to Low Earth Orbit (LEO), 2% of launch pad mass gets to Geostationary orbit (GEO) and 0.5% of launch pad mass gets to the Moon and Mars. Only 20,000 tonnes have been delivered to space: 1957 to 2020. Half a million tonnes are required to make a moon base, and 1million tonnes is needed to build a space station on Mars.
Adrian introduced us to Konstantin Tsiolkovsky (1857 – 1935.) As well as defining the rocket equation, Tsiolkovsky was the first to think about alternative ways of accessing space.
Inspired by the fiction of Jules Verne, Tsiolkovsky theorized many aspects of space travel and rocket propulsion. He is considered the father of spaceflight and the first person to conceive the space elevator, becoming inspired in 1895 by the newly constructed Eiffel Tower in Paris. It is said Konstantin Tsiolkovsky saw the Eiffel Tower and thought of keeping going.
Other scientists and inventors have also suggested or proposed other ways to get further to space and, perhaps, even to survive there
One of these was Yuri Artsutanov (1929-2019), born in Leningrad and a graduate of the Leningrad Technological Institute. He thought of “Into the cosmos by electric train” and its features - which describe the basic concept of the Earth Space Elevator today.
In the year 2000, NASA’s Institute for Advanced Concepts (NIAC) Commissioned Dr. Bradley C. Edwards to examine the reality of the space elevator. He reported phase 1 in Oct 2000 and then phase 2 in March 2003.
A space elevator is conceived as a cable fixed to the equator and reaching into space. A counterweight at the upper end keeps the center of mass well above geostationary orbit level. This produces enough upward centrifugal force from Earth's rotation to fully counter the downward gravity, keeping the cable upright and taut. Climbers carry cargo up and down the cable. It is a direct lift from the surface of the Earth up into space and back down again.
The elevator is based on solid foundations of science and engineering and will be the biggest civil engineering infrastructure ever created. This will be challenging to build. However, it is not impossible. All supplies and components need to reach the space station, and the challenge is overcoming the weight and stress involved.
Adrian concluded by saying Graphene would play a major part in the construction of the ‘Stairway to Heavens’. The first of many questions from the audience was ‘What if a plane crashes into it?’ The proposed construction will be off the southwest coast of Africa where aircrafts don’t fly over because of its location.
His talk was much enjoyed by our audience who gave a well-deserved round of applause.

Here is the report from Colin about the April u3a meeting — David Hardcastle and his Travelling Police Museum.

The guest speaker at the u3a Todmorden members meeting in April 2026 was David Hardcastle, with his ‘Mobile Police Museum’. Most, if not all of the exhibits, were already laid out on a long table and David said he would try his best, in the time allotted, to describe and speak about as many as he could. David had already worked in the Bradford Police Museum and, during that time, suggested that a mobile museum would better serve the public by taking the exhibits to where they lived, rather than them travelling to Bradford. Before starting the actual presentation, he mentioned having another one in the evening, and that we would watch and listen to the eighth show this week.
During the talk, David passed the items he spoke about to the audience to examine, but advised against trying them out with their neighbour in the next seat. He mentioned, for example, that he did have keys for the numerous pairs of handcuffs passed round, but there could well be a delay in releasing any members who tried them out. Handcuffs have throughout the history of policing, been the main, and simplest, means of controlling someone who has been arrested, or who is resisting arrest. Similar advice followed with regard to the several truncheons which circulated, David advising that these weapons were designed, and meant, to kill. As we know already, most of the police officers in Britain do not carry fi****ms unless specially trained.
Most, if not all, of the audience knew that Sir Robert Peel formed the Metropolitan London Police Force. This was in 1829 and since then we still might call them ‘bobbies’ even if we, perhaps, don’t see them as often as we used to. The policing model spread around the country from then on. Sir Robert wasn’t far from us in his former years, attending Heckmondwike Grammar School before his political career.
The term ‘constable’ actually goes back to the 16th to 17th century. Parish Constables were intended to serve the monarch – and the principles of our modern police force date back to those times. They are to preserve life, protect property and to keep the King’s, or Queens peace. The constables would carry a Tipstaff, shown and passed round by David. It is a short staff, hollowed out in the middle to contain a warrant, or similar document. It would have a crown at one end, to represent and serve the Monarch. David described it as the same as the warrant card, held by every police officer in the country. If there was resistance to an arrest, or other trouble, the tipstaff had a protruding piece of metal at one end which could result in fractures for the miscreant. There were no actual uniforms at this time, so the tipstaff would confirm the authority of the constable.
These preceded the ‘Watchmen’, who first appeared in the larger cities in Britain such as York or London. These cities would have gates to enter them, which would be closed and locked after dark. The watchmen would be responsible for manning the gates, preventing contraband being brought in, and raising the alarm if a fire broke out. As time went on their duties changed, and many became guards at the Tower of London.
Some years later, the next version of policing in London – the ‘Bow Street Runners’, formed by Henry Fielding – and these officers still operated for ten years after Sir Robert Peel started the Metropolitan force.
David took us through a history of handcuffs, which included a model known, in the Metropolitan Police, as ‘come-alongs’. The person arrested had one wrist fastened, and the constable took hold of the handcuff to lead them away. If this was resisted, the officer could twist the handcuff causing much discomfort to the prisoner and gain compliance. He also showed us a short lived invention of handcuffs, supplied to plain clothes officers. The arresting officer would need to use both of his hands to open and close the handcuffs, trusting the burglar or whoever not to run off while he, or she, was preparing them.
Police officers were almost exclusively male up until around the end of the First World War. More women became police officers from then on, presumably because of the casualties of the conflict. The first uniforms issued to the women, which included long and heavy skirts and dresses, might not have been the best garments to carry out their duties. Policewomen would not be issued with trousers until the 1980’s.
He showed us some women police officers hats from the 1960’s in Australia. They would have been modelled from their original headwear in Britain which was issued after the Boer War, and painted black. He reminded us of the BBC series, ‘Juliet Bravo’, from the nineteen eighties, by this time the hats would made of polycarbonate. He went on to show a number of hats worn by women officers, by wearing them himself - to much amusement from the audience. One of the hats was from a now disbanded police force - The Royal Ulster Constabulary (RUC) which changed to the Police Service of Northern Ireland (PSNI).
David’s millinery collection included one obtained from ebay. This was, or is, a hat worn by an assistant Chief Constable of Police Scotland. David had his own theory of how the hat found its way to that supplier, but trusted our audience to keep it under their own hats.
He produced another rare early piece of equipment, a forerunner of the torch. This was a Victorian "bullseye" lantern, used by police from the 1820s for around 100 years. This was being passed round the audience, and David asked a member to read out some writing on the piece… “Bourneville Cocoa”. An officer, formerly an engineer. had been issued this lamp and had repaired it at home. The lantern was still in use right up to the 1950’s. David showed another artefact from a few years earlier, during the second world war – a gas mask. The item probably wouldn’t have been much used at this time, but perhaps that was just as well - as the filter in it was made of asbestos.
Around the same time, in Todmorden, there were no sirens or suchlike to warn of air raids but David assured us that a rattle, similar to those used years ago at football matches, would be deployed. He demonstrated this rattle, secure in the knowledge that the audience were still awake.
Towards the end of the presentation David showed, and demonstrated some items still in use by the police today including Motorola radios – which nowadays have a feature that will identify where an officer is calling from – very useful if they are in trouble of some kind. He also had two Tasers in his collection, which when deployed by the police can deliver up to fifty thousand volts if and when required. For violent public order occasions, and if threatened, officers can deploy their ‘Asp’ to any attackers without having to get too close to them, which serves to prevent injuries and disperse crowds.
Our members may well be convinced that this travelling museum was much better, and more fun, than a trip to Bradford and back.

This should be interesting. Come and join us on Thursday 21st May.

This month’s talk was given by retired journalist and author Brian Groome who took us on a journey through the history of:

‘These isles’ - England, Scotland, Wales and Ireland

Brian began with footprints discovered on a beach in Happisburgh, Norfolk which have been shown to be roughly 900,000 years old, the oldest hominid footprints ever found outside of Africa and the only evidence of early pleistocene hominids ever found in the UK. He went on to describe the much more recent the history of the Celts, Romans, Anglo-Saxons, Vikings, Normans and others who have occupied these islands, along with their culture and languages.

He covered the Roman and Norman Conquests, the Wars of the Roses, the Tudor period (including the ex*****on of Mary Queen of Scots in rather graphic detail!), the English Civil War and he explored the role of religion, the rise of the British Empire, the seeds of the “Troubles” in Ireland and the consequences of Two World Wars - all in under an hour!

Along the way he commented on the consequences for the lives of the inhabitants of ‘These Isles’ including the people of Yorkshire.



In giving the well earned Vote of Thanks, I commented on the comprehensive nature of his “Whistle-Stop Tour” of 900,000 years of history and the fact that he made mention of the effects on the people of Todmorden and the Calder Valley.

Brian’s Talk was based on his book ‘These Isles’ published by Harper Collins in February of this year.
