The term sandy vagina is one of my favourites. I want to be mad at you but I just can't...Oh noes the muslims would kill us all............sandy vagina cork, extra sandy.

I'll pay you cash.
But let's not explore that idea when I visit LV. For some reason I think you and I would get along awesome to be honest.
... and since you're single, give her a call.Sounds like a lovely woman.
A fallen angel created it. Not the "God" you speak of.There is no reason why a supposedly benevolent God would create such a place.
The external quantum efficiency for photocurrent, usually expressed as a percentage, is the number of electrons flowing per second in the external circuit of a solar cell divided by the number of photons per second of a specific energy (or wavelength) that enter the solar cell. None of the solar cells to date exhibit external photocurrent quantum efficiencies above 100 percent at any wavelength in the solar spectrum.
The external quantum efficiency reached a peak value of 114 percent. The newly reported work marks a promising step toward developing Next Generation Solar Cells for both solar electricity and solar fuels that will be competitive with, or perhaps less costly than, energy from fossil or nuclear fuels.
Multiple Exciton Generation is key to making it possible
A paper on the breakthrough appears in the Dec. 16 issue of Science Magazine. Titled “Peak External Photocurrent Quantum Efficiency Exceeding 100 percent via MEG in a Quantum Dot Solar Cell,” it is co-authored by NREL scientists Octavi E. Semonin, Joseph M. Luther, Sukgeun Choi, Hsiang-Yu Chen, Jianbo Gao, Arthur J. Nozikand Matthew C. Beard. The research was supported by the Center for Advanced Solar Photophysics, an Energy Frontier Research Center funded by the DOE Office of Science, Office of Basic Energy Sciences. Semonin and Nozik are also affiliated with the University of Colorado at Boulder.
The mechanism for producing a quantum efficiency above 100 percent with solar photons is based on a process called Multiple Exciton Generation (MEG), whereby a single absorbed photon of appropriately high energy can produce more than one electron-hole pair per absorbed photon.
On December 14, the National Renewable Energy Laboratory, or NREL, announced that it had confirmed an efficiency rating greater than 41 percent for solar cells made by Durham, North Carolina-based Semprius.
This efficiency rating is calculated on the ability of the low-cost lenses incorporated Semprius’s gallium-arsenide (GaAs) cells to concentrate sunlight (to an intensity of 1,000 suns) on solar cells with a sufficiently wide optical angle to maximize solar insulation and reduce tracker costs.
The company is using GaAs, but notes on its website that other semiconductors are also suitable, including silicon, amorphous silicon, gallium nitride, indium phosphide and even diamond, since the original substrate can be used repeatedly.
The result is concentrating solar photovoltaics, or CPV, from triple-junction GaAs cells a mere 600 microns in diameter. The cornea in the human eye is about 560 microns thick.
Perhaps the most important part of Semprius’s manufacturing process, and the innovation that earned them $500,000 in stimulus seed money in 2009 and a spot, in 2010, with the U.S. Department of Energy’s (DOE’s) SunShot Initiative program, is their massively parallel patented micro-transfer printing.
This process allows fabricators to use standard semiconductor processes to print a solar cell and then transfer the “print” to another substrate so that the original substrate can be used again and again. The process is also applicable to other forms of manufacturing as well.
Yeah, that's right. Technology NEVER improves.Poor HA. I remember when he tried to tell me that solar tech was more or less topped out in potential efficiency.
If I wasn't so happy and secure I'd probably be bothered by your extremely personal jabs.... and since you're single, give her a call.

So far, it's still the old technology.......at breakneck competition levels. There is a German company that has reached 20% yield commercially, but there is still no major game changer in yield. Panels themselves came down in three years from $2.20 per watt to $1.10, which is good, but still not the $1.00/watt net including inverters and supports.
The day we can spend a grand or two for a couple of 4x8 solar panels yielding what a household consumes for the year will be the day the game changes forever. As an example, everyone in Greece uses solar for their hot water. It's a very mature technology that has reached a point where you go to the local distributor, order one for 500-600 Euros and the next day, they come to install it. For the next 15-20 years, you have trouble free hot water (most of the time).
I'm simply genuinely curious if you believe in heaven and hell.......
I find it amazing that there are people this smart to figure this stuff out. Hell the title of the first article alone is so complex. The capabilities of the mind is amazing
The only problem with that is that it's pure garbage.
This is what I said.....
I said CURRENT COMMERCIAL solar technology. I also said that we shouldn't be paying for current technology because it made no sense financially. AND I also said that I support future breakthroughs as long as they were COST effective.
As for wind turbines. I said that it's a mature technology (90%+). I also said we have reached close to the end on cost versus size since going higher raises the cost geometrically.
If this was a nothing but a pot shot then......
.......poor you, Googling isn't making you smarter......or funnier. :thumbsup(22):
That's good coke-convo lol.
I do believe people were just as smart, we're just better educated in general now. Differently as well obviously.
