This is easily possible. In fact, you could do better than that. Ever thought about what dsl is? It is just another modem. It uses the same wire a 56k uses. So why can't you go faster than 56k? (actually 53k, FCC limit) It has nothing to do with modulation. It has everything to do with the fact that when you use your modem, you are not talking to the other modem, you are talking to a telephone company CODEC that GREATLY downsamples your data (and sends it DIGITALLY to another codec that then converts it back to go to the modem at the other end). Good enough for voice, but it caps your speed on an analog modem GREATLY. As long as that codec is in the way, your speed capped it shall be.
We have had the technology for essentially unlimited energy for about, oh, at least 30 years. Its called nuclear reprocessing (i.e. the "choice" stuff we have to run out reactors will run out but its fairly simple to make more). True, it isn't being used out of fear, but if we ever get close to running out of other energy sources everyone will happily go to nuclear, cause it would be cheaper (and by that time, the waste and safety issues should have fairly solid solutions. Waste can be reprocessed, plants can be made much more foolproof with different reactor designs)
