Oriental Hornet: Expert Solar Power Harvester

Posted in Environment and Sustainability | Photovoltaic Cells | Solar Power

Hornet Solar Power Do you know who is the most competent solar power expert, according to a research team from Tel Aviv University? It is the humble common Oriental hornet found in our gardens! Much to the astonishment of the scientists and researchers, the hornet utilizes solar power much like a plant and it produces electricity. Think how much easier it would be if only we could unravel how the hornet manages it. This discovery could revolutionize future solar power harvesting.

Photosynthesis process

Plants use the photosynthesis process to harvest energy from the sun. Scientists have been trying to mimic this for energy production, but with limited success. Now with hornet showing how to efficiently convert the sun’s rays into electricity, there is hope for other biological and living beings to follow suit and produce electricity themselves. This research opens up a lot of possibilities.

Research team

Tel Aviv University’s School of Physics and Astronomy research team, comprised of Prof. David Bergman, Marian Plotkin and (late) Prof. Jacob Ishay of Sackler Faculty of Medicine. Together they have been busy researching the hornet in an effort to mimic it’s solar harvesting abilities.

Hornet’s unique prowess in photosynthesis

From their research we have learned that the exoskeleton – the outer body shell of hornet, works by converting the abdomen of hornet into tiny solar cells. German journal, Naturwissenschaften, published these newly discovered powers of hornet. Another study has also found that the hornet’s biological harvesting capacity is directly proportional to the intensity of the sun.

What makes hornets remarkable?

The researchers were quite keen to learn more about the activity pattern of hornet. What is the most important aspect that makes the hornet more active in the afternoon, where other insects are more active in the earlier part of the day? Considering temperature, humidity and solar radiation, they found that UV B rays are the reason for the hornet’s activity level increasing along with sun’s intensity.

The photovoltaic pattern

The hornet has some really astonishing brown grooves to split the light into diverging beams. The brown and yellow bands absorb the radiation from sun. While the brown splits the light, the yellow pigments convert it into electricity. In the small pinhole depressions, there is xanthopterin – a pigment which along with the grooves in the brown bands and pinhole depressions makes electricity from sun rays. The outer shell locks in the light which is converted to power by the pigments.

Unique characteristics of the hornet

Along with harvesting solar power, the hornet has its own built-in top quality heat pump structure in its body, which is tuned to the highest grade of efficiency. While it gets more and more busy in the hot afternoon sun, it keeps its body cool – a rather difficult thing to do. The acoustic prowess of hornets guides them to build nests in total darkness but with remarkable accuracy and exactness.

Duplicating the hornet

Though the researchers tried to duplicate the hornet’s body structure in an effort to harvest solar energy for electricity production, they have yet to find success. Efforts are still ongoing to refine the model and seek better ways to emulate the hornet for power solutions. Let us hope that a successful prototype is soon realized, so we can harvest renewable solar energy as effortlessly as the hornet!

    I’m glad they are useful.

  • Reed

    The key certainly isn’t something profit motivated.

  • Jasmin

    What beatiful creatures… amazing how much more advanced they are than us lol.

  • Dan

    Now you’ve done it, Monsanto and GE will genetically modify hippos with hornet DNA, and make them live wired to the electrical grid… lol

  • William

    I have a new found respect for my nemesis.

  • Marianne

    yeah, well… the bees are dying already because of our cell-phone use. wonder if the hornets will stay alive long enough for us to study them.

  • Champion

    Those things are some mean muddas. Great to hear there is a use for them!

  • Orin

    They share my carport with me and it’s not always a peaceful coexistence, I know they are living in my walls, wonder if it’s lighted up like Las Vegas in there with all that solar power?

  • Kevin

    Researching all the wrong places…we are killing insects so fast, what we discover today is extinct tomorrow…

  • Denis

    Save these are devastating beehive in western europe…

  • Temo945

    That will only be temporarily, while it gets killed along the bees by so many pesticides
    being used.

  • 1goodcat

    Wasp with tazers?

  • science guru

    What about studying electric eals? Don’t they make a large amount of electricity?

  • science guru

    OOPS I meant to say eels

  • Vilas Khadse

    Nice information. The curiosity leads to invention and discoveries !
