Solar power relies too heavily on the weather, IMHO. A few cloudy days, or one good thunderstorm, will pretty well sink an array.
Does that mean that we don't use it? Or that it should never be used as an addition? Nope. I especially think that it's good for water heating (the water serves as a convenient long-term heat sink, and is nice, but not absolutely necessary). But I think that these pie-in-the-sky articles hurt more than they help, becuase it gives people that don't know the first thing about electricity or power generation the ammo to say "See I told you so...". Like the fool on FR that told me the US could convert 100% to wind power because "Denmark did it."
That's just my 2c.
I didn’t consider this a ‘pie in the sky’ article. It’s simply informing folks that more research is being done by the day to make this more feasible for more folks down the line. The more arrays that are sold, the more money for the companies to do research, and as with all new technology, the ones in the first wave always pay more, while after the technology has been in use and the kinks are worked out, the next wave pays a little less, and so on.
