I guess i'll test the waters with some staple Early PMT tech.
Tech Level: Early PMT
Tech Name: Railgun
Military/Civilian: Military
Mass Production: Power restrictions would mean in this time period, no. Not man portable.
Cost of Tech IRL: Development would likely be in the hundreds of millions, however simply constructing a railgun would not be prohibitively expensive. The energy source is the most expensive component. Ammunition is also fairly cheap when compared to conventional explosives. Maintenance is minimal as well. Source:
http://en.wikipedia.org/wiki/RailgunTech Level: Early PMT
Tech Name: Anti-Air Laser
Military/Civilian: Military
Mass Production: Yes/No Power restrictions mean it would need to be mounted on something capable of producing lots of energy, such as a warship or defensive installation. Not man portable.
Cost of Tech IRL: Hundreds of millions in development, requires a large source of energy for operation.
Tech Level: Early-Mid PMT
Tech Name: Sub-Orbital Flight
Military/Civilian: Both, but mostly civilian
Mass Production: Yes/No N/A
Cost of Tech IRL: Expensive, but would reduce fuel costs and travel time across great distances, such as between continents.
Tech Level: Early-Mid PMT
Tech Name: Quantum Computing
Military/Civilian: Both
Mass Production: Yes/No N/A
Cost of Tech IRL: Huge development costs, but would revolutionize computing. Exponentially increase processing speed and allow for smaller, more powerful computers. Eventually, the cost burden might not be too much for personal use, but initially would be restricted to major corporations and state armies.
Tech Level: Early PMT+
Tech Name: Artificial Intelligence
Military/Civilian: Both
Mass Production: Yes/No N/A
Cost of Tech IRL: Most would be sunk into development costs. In the earliest stages, could be used to automate many functions, from shipyard loading/unloading management to warship combat functions beyond those capable of modern automation technology. Would likely need quantum computing.
Tech Level: PMT
Tech Name: Mobile Suits (Mecha)
Military/Civilian: Both, civilian at first, military application later.
Mass Production: Yes/No Early on, no. Late, possibly.
Cost of Tech IRL: Extremely costly, and only the most advanced industrial nations could afford this technology in the near future. Prohibitively costly due to limits of mechanical engineering which would need to be overcome, but IRL USA/Japan have made great strides in this regard. Initially would likely be used for industrial applications, such as a more manoeuvrable/durable forklift. Think of the suits from Alien. Military applications are possible, and initially could revolutionize warfare by further increasing the mobility of armour, however this would likely be a bit further in the future. Thinking the earliest Knightmares from Code Geass.
