    Why did you ask me if they exist after we had that looong conversation about EnergyStar? Of course they exist. You haven't explained how your system is better than the leftist system that already exists.

    I just want you to confirm it exists by providing your source of information. I'm not going to just take your word for it. You have bluffed before.

    Are you going to provide your source of info or not? I don't like asking multiple times. Why are you stalling?

    Read back 4-5 posts when you first asked the question.

    You never answered the question. You asked me the same question because you were bluffing and don't know of an efficient DVD player as you claimed.

    Dishonest bluffing isn't science. If you are embarrassed you should be. If you need to lie it says something about your character.

    Thanks for clarifying, that makes sense. Every long-term scalable option for renewable energy will have significant challenges to over come. This seems like a relatively minor one. Couldn't you insulate the wires in the solar cells?
    The problem there is the very low frequency of the power lines, 60 Hertz or 50 Hertz usually, some 25 Hertz and some 400 Hertz (mostly military). Anyway, all of those frequencies are very low and hard to insulate, the solar cells themselves would interact with the volatge induced by the proximity to the wires in the pylon. The power leads could be insulated by having them covered by braided shielding going to ground and that would have to happen for all wiring. Dual wire coax is what that is called, two inner conductors covered by some kind of flexible plastic insulation then the braided conductor and then an outer coating of another tougher plastic outer layer. The down side is those cables are about a dollar a foot so a large installation would be expensive maybe more than a buck a foot.

    That would shield for electric fields but there is also magnetic field shielding to consider. Considering the magnetic field part of the wave can also induce electric currents, you would need to shield against that also and that would be with an outer mu metal shield or some sneaky stuff like this magnetic shielding putty:

    Hmm. Ok. Someone will come up with an innovative solution at some point. I hope it comes before we raze even more undeveloped natural spaces in the name of green energy. If you ever get to Vermont, head to the NEK and see for yourself what a disaster it is. That area had more moose than people living in it, clean water, hiking/camping/hunting areas, but now its a loud wind factory, subsidized by green energy and done in the name of environmental protection. A thousand acres of pristine wilderness destroyed to power a small percentage of households in that state. Unbelievable.

    What is it replacing is Yankee power, a nuclear power plant that was decommissioned after lobbying efforts by supposed environmentalists. This plant once powered the entire region, including the entire state (not a fraction of the state), on a footprint 1/100th of the size, with zero emissions.

    edit: after looking it up, Yankee power plant powered 35% of the state. Its still far greater than wind power capacity.
