    Australian solar power researchers have achieved world-beating levels of efficiency at 40.4%

    Australian solar power researchers have achieved world-beating levels of efficiency, potentially making large solar plants more competitive with other energy sources such as coal.
    A team from the Australian Centre for Advanced Photovoltaics (PV) at the University of NSW has achieved 40.4 per cent "conversion efficiency" by using commercially available solar cells combined with a mirror and filters that reduce wasted energy. 
    Martin Green, the centre's director, said the independently verified breakthrough eclipsed previous records without resorting to special laboratory PV cells that "you've got no chance of buying commercially". Other top-performing solar panels convert about 36 per cent of the sunlight that falls on them into electricity.
    The advance involved two steps. Three solar panels were stacked to capture energy from different wave lengths of sunlight, and then excess light from the stacked panels was directed by a mirror and filters to a fourth PV cell, making use of energy previously discarded.
    "This is our first re-emergence into the focused-sunlight area," said Professor Green, who pioneered 20 per cent-efficiency levels in similar technology in 1989.
    The institute was prompted to revisit the technology in part because of Australian companies' efforts to develop large-scale solar towers using arrays of mirrors to focus sunlight on PV cells.
    One of those firms, Melbourne-based RayGen, collaborated with UNSW on the project. It is building a plant in China with an solar conversion rate of about 28 per cent across the year.. "We'd take them to the mid-30s" for future projects with the technology jump, Professor Green said.
    Professor Green was critical of the federal government's efforts to scrap the Australian Renewable Energy Agency – which chipped in $550,000 to the $1.3 million Power Cube project – and for its ongoing attempts to reduce the Renewable Energy Target set for 2020.
    "A positive attitude to renewables would boost all these initiatives, a negative attitude will suppress them," he said. "Clamping down on deployment of renewables will make it more difficult for developments like this to see the light of day."
    The next goal is to raise efficiency levels of concentrating solar to 42 per cent next year, about half way to the theoretical maximum level of 86 per cent. It's an issue likely to be discussed as Sydney plays host to the Asia-Pacific Solar Research Conference this week.

    1. O K. I give up . How many home owners don't know if there is a gun hiding in their house?
      I am not really well informed but, I don't think I can remember a case when gun crawled into someones home searching for a place to hide.

      We are from the government, we have guns and cages, and we are here to help "educate".

    3. Where are the MANDATORY firearms safety classes for Children? "They" insist mandatory sex education is indispensable.

    4. Have you ever heard of an ARMY that was not allowed to have arms/weapons by It's own government?
      Find one government in the entire history of humanity that felt a need to document a "RIGHT" for it's soldiers to carry weapons.
      The claim that the Government wrote the 2nd Amendment to give Our soldiers a "right" to carry weapons is S-T-U-P-I-D.
      The only reason for the Second Amendment is to clearly spell-out the GOD GIVEN RIGHT of INDIVIDUALS to keep & bear ARMS.
      The only reason for the BILL(list) of RIGHTS was to codify INDIVIDUALS' GOD GIVEN RIGHTS.
      Has there ever been a government that was not chock full of it's "rights" up to and including declaring itself to be the Lord God Almighty?!

    6. Yup. Gotta be the gun's fault. Next up knives. Then baseball bats. Then pop tarts

      Most state capitols are run by conservatives. It's a sea of red out there. This article points the finger of blame and hypocrisy at exactly the wrong crowd. Dems don't control too much of anything anymore.

    8. They could make a reality show out of this called "What Schmuck Wants to be My Next Bust?!" With gazillion laws and regulations, does anyone think the cops will restrict themselves to rummaging through your house for guns?

    9. (1) Romney(RomNEOCON) signed an "assault weapons ban"
      (2) Many people have the delusion that there is a DIFFERENCE:
      Tweedledee&Tweedledum .... neocons&liberals (neocon was INVENTED by the TROTSKYITE COMMUNIST Irving Kristol)
      If THIS does not make you PUKE ........

      George W. Bush: Hillary Clinton is like ‘my sister-in-law’
      By Jose A. DelReal December 5 at 10:16 AM
      Former President Bush has spoken at length about his close ties to former President Bill Clinton, at times calling him his "brother from another mother."
      CNN's Candy Crowley asked Bush during an interview published Friday where that leaves Hillary Clinton: "My sister-in-law!" the president responded light-heartedly.
      (3) NeoCon was INVENTED by Irving Kristol and his CABAL of TROTSKYITE COMMUNISTS.
      NeoCon is COMMUNISM wrapped in an American flag.
      NeoCons refuse to WEAR an American uniform ....
      they just wrap themselves in the flag and send YOU and YOURS to be maimed and killed.
      Today's American NeoCons are yesterday's Bolsheviks. SAME THING.

      Does the 1st Amendment mean the GOVERNMENT is allowed to give speeches? Try shutting up any Government.
      Anyone who tells you the 2nd Amendment applies to the Army or State Militia, is telling you they think you are STUPID.
      There has NEVER been a government that felt it had to codify it's army's/soldier's "RIGHT" to "Keep and BEAR ARMS" because there has NEVER been a government that refused to allow It's own soldiers to KEEP and BEAR ARMS!

    12. This is such a worn out debate.
      I do not care what any man, cop, king, congressman, judge or global tyrant thinks about guns; I shall never relinquish mine...

    13. To what end? Would these same police give any citizen free access to their home to search it at will ? They are traitors to their oath.

    14. Ryan,
      I've never really thought about the second amendment in quite this way before...your's was a great reply. I hope you don't mind if I quote (and credit) you in the future when I argue liberal socialists about gun control in the future.

    15. Feel free to do so. The entire purpose of Free Speech/Press is to spread Thought through Society. And I am proud that you feel my thought is worth spreading. I do not need any credit. Every little bit that I can do to help save FREEDOM is it's own reward.
