- Mirrorswarm uses SI units and Earth time (day,hour,year,kg,s,mol,cd,Ampere,Kelvin,m). E-notation with no spaces is acceptable.
- The host planet Mercury ("Host") is low-gravity which will help get the swarm into orbit. It is close to the the swarm which orbits between the host and the sun.
- Avogadro says there are 6E23 atoms in every mol of material. A mol of the elements of the host is 54g.
- The raw material for the swarm and its factories is elements. These elements will be extracted from the host. There are fewer then a hundred elements needed.
- The construction material for the swarm and its factories is the minibot. This is a general purpose machine possibly consisting of fewer than 1E20 atoms (0.25g). Teams will specify the performance requirements and design of the minibots.
- The 1% of the host which is available as raw material has a mass of 3.3E21kg and makes at least 1.3E25 minibots with 0.1% refinery efficiency.
- There may be four generations of mirrors...
- The fab has to arrive on site with a prefabricated energy generating capacity which may involve taking first-gen mirrors, or maybe just solar panels.
- Second-gen ground-based mirrors and planet-orbit railgun are ground-manufactured to ramp up energy.
- Third-gen mirrors are launched as 1-mirror factory packs and made in zero-G to swarm in Mercury orbit, powering just the site which makes the escape-velocity railgun.
- Fourth-gen mirrors are launched as 1-mirror factory packs and made in zero-G to swarm in Solar orbit, powering the whole system. We have a likely mass limit of 20 tonnes on each launch based on a 1km2 mirror at 5g/m2 = 5 tonnes and a feasible overhead of 3x for the factory which makes the mirror in zero-G and the coupled power transmitter. Is there an efficiency benefit in orders-of-magnitude larger mirrors or do we leave that choice to the swarm which will replace this prototype?
- The site needs receivers to translate light to usable power. Forms of distribution around the site could include microwave/WiFi, light, electric, hydraulic. Some components also definitely need a power store - any form of railgun, for example.
