    Carbon nanotubes could increase solar efficiency to 80%

    Carbon nanotubes could increase solar efficiency to 80%

    Still need better batteries, but that is only a matter of time.

    Perhaps one of the greatest challenges facing solar technology is wasted heat. One crucial measure of solar panels is how efficient they are in converting the sun's rays into electricity. So it's potentially huge news that a team from Rice University has produced a method they say could radically improve solar panels work.

    It's not that the scientists have created significantly more efficient solar panels. Instead, they're working to capture the thermal photons—the heat—those panels are releasing.


    “Thermal photons are just photons emitted from a hot body,” says Junichiro Kono of Rice’s Brown School of Engineering in a press statement. “If you look at something hot with an infrared camera, you see it glow. The camera is capturing these thermally excited photons.”


    When the sun transmits heat and light, it also sends an invisible energy known as infrared radiation. Humans have been able to utilize infrared radiation in a variety of ways, ranging from personal saunas to weather satellites. But it doesn't take up much space in the electromagnetic spectrum.


    “Any hot surface emits light as thermal radiation,” says Gururaj Naik, who coauthored the resulting paper with Kono and others, published in ACS Photonics. “The problem is that thermal radiation is broadband, while the conversion of light to electricity is efficient only if the emission is in a narrow band," Naik says in the press statement.

    That sounds huge! I wish i could remember to follow things like this because sometimes you never hear anything further. Hopefully we will with this. If we can quit burning stuff to make energy so many things become possible.

    If you want solar or wind power get ready to dig. It takes 10 times the digging to produce solar or especially batteries as it does coal or oil and gas and all of the minerals needed are irreplaceable. Solar takes lots of land for panels. Wind power takes a lot of oil for the composites and plastics. The amount of steel and concrete needed for wind power is huge.

    I would bet at some point in time environmentalist will end up stopping both.
    When Donald Trump said to protest “peacefully”, he meant violence.

    When he told protesters to “go home”, he meant stay for an insurrection.

    And when he told Brad Raffensperger to implement “whatever the correct legal remedy is”, he meant fraud.

    War is peace.

    Freedom is slavery.

    Ignorance is strength.

    What? How does that work?

    Precious metals, steel, concrete, plastics just don't appear at Home Depot by magic.

    Hopefully it can lead to a new Energy Revolution.

    Indeed, an Energy Revolution can lead to a Post-Scarcity Civilization.

    If it can lead to a new economic boom and Post-Scarcity Civilization, it will not be stopped.

    Hopefully many Social Conflicts related to Money and Resources will be History.

    All utopians believe as you do.
    Call your state legislators and insist they approve the Article V convention of States to propose amendments.


    I pledge allegiance to the Constitution as written and understood by this nation's founders, and to the Republic it created, an indivisible union of sovereign States, with liberty and justice for all.

    Hopefully one day All Humans will live a life of Happiness and Prosperity. People in that generation will not understand how in the past ( pre 2050?) people had arguments and wars over material goods.
