Re: which one first? i don't know, but my guess would be hydrogen cars...
one thing that hydrogen cars has going for it is that the well established equivalent (gas cars) is that the supply of gas will probably force hydrogen cars to be cheaper, thus an economic incentive. when looking at BPL vs well established equivalent (cable, dsl, fiber in places, and rarer wifi or wimax), i don't see what BPL has going for it. there are interference issues, lesser theoretical capacity compared to fiber, coax, and possibly twisted pair phoneline, what BPL will be competing against is already well established for the most part (dsl and cable and soon (wishful thinking) to be fiber). i'd say BPL is at best an interm solution for locations very rural areas. |
