SUBMIT YOUR IDEAS

Volunteers are invited to contribute by submitting ideas for the project. Submissions may involve working on a specific question or developing an application, but must be clear, complete, and self-explanatory—requiring no additional explanation to be useful to others.

Please submit a maximum of 5 files. These can include a video or photo

but must be accompanied by a PDF document (maximum size 10 MB).

Documents must have your name, date submitted and contact details.

Where possible, include engineering details, scientific analysis, and supporting data. These contributions will form a growing archive developed alongside the Promethean Nexus Communities’ existing knowledge base.

Please note that all submissions will be reviewed, as not every idea will align with the core philosophy of the project. If successful, this archive will eventually be made publicly accessible.

Use the form below to submit your ideas.

City layout

How could a city of 10 000 people be designed where it is simplified and is less complex to operate?

Describe ideas about how civil engineering structures and networks could fit into our proposed city.

How could a city be designed where it is easier to maintain, and it is designed to last as long as possible?

How could a society in our proposed city be run on fewer components (for example instead of having 1000 different kinds of electric motors, could we operate on just 3 or 4?).

If those components were designed to be recycled locally, what would they be made out of?

If we set up a series of pilot scale industrial sites (like a smelter to do casting), and we used additive manufacture (3D printing), could we manufacture those components locally? If so, how?

Building construction

How would you develop new ideas in architecture, ensuring they would fit with the overall innovative city concept?
What would the underlying support systems (drainage, sewage, power cables, etc.) look like in buildings in a concept city? How might efficiency measures like roof top solar hot water be integrated?
What might the internal floor plans of some of these buildings look like?
If you were to design a hospital, school, fire station, community space in this setting, what would it look like?
How might unorthodox building materials be used?

Energy

Describe ideas and concepts to be energy effect in designing and operating a city of 10 000 people.
Describe how a decentralized energy/electricity grid network could look like in a city of 10 000 people (Power generation will be local and would range from 2 MW to 100 MW installed capacity). Transformers, underground cables, to domestic housing.
Describe an energy efficient and water efficient home for 4 people.
Assemble ideas that describe efficient wind turbines and solar panels that can be produced from simple components (for example not needing exotic metal alloys that are only available in a few parts of the world). They should be designed to be recycled (at the moment there is no recycling solution for wind turbine blades, and they are often land filled).
If solar hot water was used in a city of 10 000 people, what design would be used and how would it operate? Hot water for showers, laundry and dish washing in domestic housing.
Could we use syngas or methane for domestic cooking in some applications? If so, how would it be applied in a city of 10 000 people?

Water

Design a potable drinking water system for domestic needs for a city of 10 000 people. What water quality measures would be taken for safety mitigation of bacteria load (so people don’t get sick). What efficiency measures could be taken? How might this interact with the grey and black water systems?
What would an effective grey water system design be for an innovative city of 10 000 people?
What would an effective black water system design be for an innovative city of 10 000 people? What would we do with the sewage solids? Pyrolysis to make syngas & hydrogen? Fertilizer? Gasification to produce methane for cooking?
Could we make a water circuit that takes grey water first, then the grey output is used as sewage (black water) inputs second? The black water output could then be used as agriculture irrigation, or biosystems region irrigation.

Waste handling and raw materials

Describe a waste handling and collection network for a city of 10 000 people. As much waste as possible will be collected, recycled or valorised. What do we do with the waste streams? Circular Economy, Steady State Economy. How do we do this? This will be on the Spine Rail Arterial Transport line.
Design a waste transfer station with sorting technology (robots are now viable) to prepare and stockpile waste streams as feed stock for other industrial plants in the city. Interact with the Spine Rail Arterial Transport system.
Design a series of pilot scale hydromet plants that would extract metal from, or clean metal streams recycled from sorted waste. Network. them all into the same nested complex. This will be on the Spine Rail Arterial Transport line.
Design a pyrolysis plant that processes rubber tires (all sizes that are shredded) and produces many products. Fuel oil, diesel substitute, rubber pellets, carbon black, steel scrap. The carbon black can be used to produce graphene.

Data management

Describe a data management system (using blockchain tech?) that tracks and audits the consumption of materials and waste in our city of 10 000 people, without surveilling people themselves.
Design a data management center. Like a data control center used by mine sites to manage and run a modern mine. Run by 5 to 10 data scientists, supported by 5 to 10 technical experts. Its purpose would be to ensure there are no shortages of any kind. Optimize consumption, energy use, water use and city environmental footprint. Eventually this will be owned and run by City Hall.

Manufacture

How could 3D printing be used (metals, ceramics, glass, rubber, biodegradable plastics)? In what applications would be useful in a Venus Project city of 10 000 people?
How could we produce feedstock for 3D printing from raw materials sourced locally (rocks, mining waste, industrial waste)? We will have heat energy up to 1960 0C (Fe combustion), industrial scale electricity and other industrial support (pilot scale). We could have a plasma torch available. This will be on the Spine Rail Arterial Transport line.
Design a pilot scale metal casting smelter that could produce multiple metals, alloys, and products. Design a network of pilot scale units to produce metal components (sheet, bar, rod, pipe, etc.). Network them together into the same nested complex. This will be on the Spine Rail Arterial Transport line.

Materials

What useful things could we make out of graphene? Why are they different to other products?
How might we go about phasing out the use of plastics? What strategically useful applications would still need plastics? If bioplastics are used, then how much, what kind, and how much biomass would be needed to produce them?
What could hemp be used for as a material?
What could bamboo be used for as a material?

Construction materials

Assemble a list of innovative and unorthodox building construction materials. Describe why each one is useful. We wish to replace the widespread use of concrete and asphalt. Short value chains required. These will be tested and validated in a Construction Materials R&D laboratory as part of the city network. Successful products will be used to construct and maintain the city.
What geopolymers (materials made from volcanic ash, rock, mining waste, or industrial waste) could be made and how could they be useful? Could we use geopolymers as 3D printing feedstock to construct buildings?
If we had access to large quantities of sea salt; how would you use it? What would you extract out of it? Metals extracted with electrochemical methods? What chemicals would you use this salt to produce (at the start of their value chain). Would you use the salt directly (medical?), or would you extract the Na and Cl out separately? If so what would you do with that Na and Cl? Make batteries? If so, how?
If we had access to large quantities of pure oxygen (from another process), how would we use it? Could we oxygenate parts of the ocean that are now dead zones? Would this help if we did this? Would we use this for chemical production of products?

Transport

If bicycles were used extensively as a form of transport around our city of 10 000 people, what would a network of bicycle pathways, park spaces look like? Underground parkways, set up like a modern car park? Dedicated traffic light systems for the bike pathways? Ease of access?
Design a charging network for 500(?) passenger car Electric Vehicles across this city of 10 000 people. How much extra power will be needed just for this task? Remember, communal transport on the Spine Rail Arterial Transport system should account for most transport needs.
Design a network of 500(?) heavy H-Cell vehicles (buses, trucks, maintenance equipment) for a city of 10 000 people. How much hydrogen? Where would the hydrogen be produced and stored? How do we mitigate safety concerns? What if we could produce hydrogen from human sewage?
Refine the design of the Spine Rail Arterial Transport system. A monorail to move people on top, an underslung pod rail system to carry shipping containers (and other container) underneath. This would move between all major parts of the city and all around the industrial sectors. What would this look like? What would a loading station look like (bottom) with a passenger station on top look like? What could the pod/container handling system do with cargo after it has been unloaded? Like a modern post office package handling facility that has multiple sub handling systems.

What are the parts of this (emergency, general practice, dentist, surgery, pediatrics, support lab services, + alternative medicine like herbal, osteopath)? How many? What resources (human and otherwise) would be needed? How would this be managed? This will be freely available for city citizens.
Design a health care system for children. Full care chain system for children and pregnant mothers. Pediatrics, midwives, childcare, etc. What kind? What size? What support resources will be needed?

Below is our plan for the collection and actioning of your ideas,

funded by Promethean Nexus

1. Collecting Ideas
We welcome ideas from everyone. You can share them through our online Concept Portal or by email. Over time, these ideas will be stored in a public, searchable database.

2. Conferences

We will host conferences—both in person and online—to discuss the development of Promethean Nexus. All sessions and outcomes will be published online, and new ideas from these events will be added to the database.

3. Expert Workshop
A group of 30–40 invited experts will meet in person to review and refine ideas for the city. By this stage, we will have chosen a location for Promethean Nexus. The team will evaluate ideas based on site-specific needs, explore how they can work together, and combine them into 3–5 practical city development plans. Engineers and construction specialists will be present to guide feasibility considerations.

4. Feasibility Studies
Several engineering firms, funded by Vulcan Catalyst, will carry out studies including:

Scoping studies
Pre-feasibility and procurement assessments
Full feasibility studies

5. Final Planning
The Promethean Nexus team will choose the best development plan, set the construction order, and finalize designs for the city and its industrial network. They will define the long-term strategy, short-term milestones, and prepare for construction.

6. Procurement & Contracts
The tender process for selecting suppliers and construction partners will begin.

7. Construction
