How are solar cells so inefficient? Initial cost may be high, but they still produce FREE ENERGY after they are installed. They produce electricity from FREE sunlight, no? That seems pretty efficient to me. Could you imagine if every house had roof tiles made of solar panels and a solar hot water system? Sure you'd still need a bit more power from the grid, so what? If you reduce fossil fuels it is a good thing. The idea of containing each dwellings power generation on the premises itself is wrong. Ever heard how deserts are called wastelands? So lets not waste'em. Solar farming makes more coin than cattle per acre. And you don't have to feed them. And they don't need water and don't get sick. Think about it for a while.
The only pollution you get from solar panels is in construction and disposal.

If I hear another person quote "conservation of energy' and 'laws of science' I'll pull my eyes out through my eatascareta. Look, IF the 'laws' of science are inviolable and complete than I think everyone here agrees that there is nor will there ever be any zero-point, over-unity or 'free' energy. Do we all essentially agree on that? so:
'Laws' of Science = status quo forever (excepting some efficiency improvements)
What everyone in this field believes is that the 'laws' of science are anything but. They believe that 'classical' physics is flawed (an absolutely true and valid fact) and that there are forces/particles/waves/states that we simply have not yet fully understood that allow these as yet unexploited aspects to be used to 'create' energy. Most likley this has nothing to do with creating energy as much as it does exploiting changes in state to do 'work'. Like photons => CdS => electricity
Stating 'conservation of energy' over and over again gets no one anywhere. It's a waste of everyone's time simply because we are all aware of that chant. Many, many believe that it will soon be filed in the same drawer as 'If man were meant to fly God would have given him wings' and ' The earth is the center of our solr system' or 'everything is made-up of atoms'. Things change. New things are learned. It's intellectual evolution and it's happening right now... like it or not.

Today you can install in the average size home for about $40,000 enough solar panels to run everything.
Salt water as fuel? Erie man hopes so
Sunday, September 09, 2007
By David Templeton, Pittsburgh Post-Gazette
For obvious reasons, scientists long have thought that salt water couldn't be burned.
So when an Erie man announced he'd ignited salt water with the radio-frequency generator he'd invented, some thought it a was a hoax.
John Kanzius, a Washington County native, tried to desalinate seawater with a generator he developed to treat cancer, and it caused a flash in the test tube.
Within days, he had the salt water in the test tube burning like a candle, as long as it was exposed to radio frequencies.
His discovery has spawned scientific interest in using the world's most abundant substance as clean fuel, among other uses.
Rustum Roy, a Penn State University chemist, held a demonstration last week at the university's Materials Research Laboratory in State College, to confirm what he'd witnessed weeks before in an Erie lab.
"It's true, it works," Dr. Roy said. "Everyone told me, 'Rustum, don't be fooled. He put electrodes in there.' "
But there are no electrodes and no gimmicks, he said.
Rustum Roy, a Penn State University chemist, has held demonstrations at his State College lab to confirm his own observations.
The radio frequencies act to weaken the bonds between the elements that make up salt water, releasing the hydrogen, Roy said. Once ignited, the hydrogen will burn as long as it is exposed to the frequencies, he said.
The discovery is "the most remarkable in water science in 100 years," Roy said.
"This is the most abundant element in the world. It is everywhere," Roy said. "Seeing it burn gives me the chills."
Roy will meet this week with officials from the Department of Energy and the Department of Defense to try to obtain research funding.

Burn water, yeah, good idea. Anyone think of the consequences and/or byproducts of such an exchange?

Even if this is not free energy could the energy of the burning salt water be as efficient or provide an equal amount of energy as oil?
