You talking about solar photovoltaic? or the new type of linear solar thermal steam generators they're already using to get FREE energy in the form of the typical coal-fired steam turbine?
The BigOil and BigCoal advocates always forget to make the distinction what type of solar power they're talking about. No, I take that back, they always name the most inefficient and most expensive or failed type of solar applications as "the cutting edge in solar".
Have a look at the real cutting edge of solar. Every day of sunshine is a day the power company doesn't have to burn coal or oil to power the towns nearby. In heavily populated sunshine rich areas of the South and Southwest, the company can not be burning coal or oil during peak use times (day) for up to 300 days per year. Talk about improving your electric company's profit margin!
Just mirrors set up in a line, close to the oil tube they're heating to 300 degrees celsius..that's right...celsius..a couple of heat exchangers, some water and a turbine just like the ones in nuclear, coal and oil power plants.
BigOil and BigCoal advocates made it excessively clear in the first post, exactly what type of solar power they were talking about.
The only person confused on that, is apparently you. Try reading, before replying.
Second, if you can find a way to fit enough steam pipes, water, and mirrors, to power a Boeing 474 Jet, by all means patent and sell it. Otherwise, all your BS pipes and steam generators are a joke.
Third, there is nothing free about it. "Sun light is free!" So is oil. We don't pay the Earth, for the oil we get either. Both are free.
The cost is in collecting that free energy, and making it useful.
Moreover, there are always bleeding edge technologies that are supposed to explode the future into this amazing Utopia.
But your cited solar thermal power, isn't even an attempt at that Utopia. Did you even look at the numbers? 13¢ per watt? Coal is 7¢, and NatGas is 5¢. So it's more than double the conventional power cost, and you just cited that as your most efficient?
Not to mention you can't find how much the entire project costs, nor can you determine how much the government of California taxed the poor, to pay these big CEO investors, to make this power station.... oh and let's not forget it's a whooping 5 MWs of power. Oh they are planning to expand it to 25 MWs of power.
Let's see, the most tiny, cheapest, smallest, least power generating conventional power plant in Ohio is...... 480 MWs. One single natural gas power plant, is equal to 20 of your solar easy bake oven power plants.
I wonder how that compares in cost. I wager not favorably.
If this is the best your "free" energy crap has to offer.... then you don't have much to offer.
Not to say we shouldn't continue research, but don't pretend that you eco-freaks have it all figured out. You got nothing. NOTHING.
