After the collapse of the nations of the nineteenth and twentieth centuries, a power void was created. The expected successors had been the oil companies, however peak oil had come and gone, leaving the shattered businesses fighting over scraps. The next most likely candidate had been the financial sector, but with the collapse of nations had come the collapse of currency, rendering them impotent. The future leaders of the world came from Silicon Valley, and other enclaves of programmers and tech industry gurus, with their rise came relaxations of traditionaly maintained restrictions on development and research. The first major innovation of the new age came in the form of cheap, effective energy, the Rolls-Royce Spheric Fusion Core. The availability of energy broke open the floodgates that had been holding back humanity for the better part of one hundred years.
List: (I am an American, and very poor at metric conversion, so I will be using the Imperial system here)
Fusion power
Fusion thrusters (allowing for thrust of up to .3 c at an acceleration curve of about .1 c per second)
Laser weaponry (we measure space combat range in the hundreds of thousands of miles, with optimum range of about 50,000 miles)
Particle Beam weaponry (the 'fuck you' gun of B12's space forces, takes minutes to charge, but kills everything)
Ion weaponry ( EA's fuck you gun, miserable at range, but will fry the fuck out of most ships at under 10,000 miles)
Rail drivers (Asynchronus linear accelerators, not the stupid-ass electromagnetic sling on youtube)
Quantum AI systems (limited by design and technology, about as intelligent as a dumb human)
Power armor (The real deal, Strength augmenting exoskeletal battle armor able to withstand almost all small arms up to about a 40mm rifle grenade, but not the .50 cal, nothing withstands the .50 cal)
Deep-space colonization and exploitation (B12 lead the pack here, explanation later)
Efficient solar collectors (seriously, they currently only collect like 5% of available energy)
Cybernetic augmentation (EA pushed this one in the form of the neural jack, a captive audience is the best kind)
The plasma-induction furnace (a B12 special, you take the waste ferrous plasma from your fusion reactor then set up a soliton to produce the kind of energy released by a supernova)
Low level gravitational control (we already know that several elements produce gravitational effects when bombarded by radiation, but this only amounts to artificial gravity of a little less than 1 g (.90-.97, and very low level anti-gravity systems, good for suppressing part of the weight of super-massive constructions)
EPR comm systems (beyond light speed communications allowing for faster internet connections even as far out as Pluto)
Graviton spin comms (B12 answer to EA's control of the EPR net, jointly developed with IBM)
Trans-orbital flight (yes, already realised, but the tech is now much more available)
I'm going to stop here for today, let's discuss what we have so far.
