Okay, I'm generally willing to give up the gravity control, I'm going to have to clear up a few points tho'.
1) fusion reactors: Toroidal-fusion reactors are a dead end, spherical fusion is a current, proven, process, in fact the test start started fusing so fast they blew out their damn power grid due to excess energy.
2) solar cells: those efficency ratings are for the specific spectrum of light the cells are built to take advantage of, my wife recieved her masters degree in geo chemistry at Colorado School Of Mines, many of her contemporaries worked at the national alternative power labs, and she vouches for the above statement.
3) Nuclearthermal (or for those unversed in the lexicon nuclear steam turbine generators): Why. Nuclear electrical induction works fine, and is many times safer.
4) particle weapons: as seen in science fiction are iffy, real world ionizing-path weapons, as tested in the 1980s are very viable, simple particle collection/charging grids are in use currently.
5)'pumped' or explosive lasers: I am going to stab Weber in the fucking heart for this idiocy, I swear to hell. A high-energy plasma laser using electro-magnetic bottle and lensing would be every buit as powerful and much less self-destructive for a much lower cost.
6) electrolasers: Otherwise known as the free electron laser, developed by Nikola Tesla, gaping hole in that weapon that no one wants to look at is it's tendancy to ground out on the nearest piece of metal. Powerful, sure, but less accurate than a sawn-off shotgun.
The plasma metal seperator sounds good, tho' low frequency sonic shockwave pulverizers work well to.
I like this feedback, it sounds like we have only a few sticking points on this list in need of further discussion, I'd like to hear any ideas you guys have for filling things out. (I realise I'm kind of sounding like an ass in this post, but the amount of tech we don't have right now due to treaties and private interests drives me completely berserk, I kid you not, I actually see red when I read about another system that will never see the light of day because some company or nation doesn't like it.)
