Small wind turbines scaled to the right size for residential and urban areas have so far lived in the shadows of their larger wind-farm-sized counterparts. The power output has been too low for a reasonable return on investment through energy savings and the noise they produce is louder than most homeowners can deal with.

A Dutch renewable energy start-up called The Archimedes is working to solve both of those problems in a new class of small-scale wind turbine — one that is almost silent and is far more efficient at converting wind into energy. The company states that the Liam F1 turbine could generate 1,500 kWh of energy per year at wind speeds of 5m/s, enough to cover half of an average household's energy use.

When used in combination with rooftop solar panels, a house could run off grid. “When there is wind you use the energy produced by the wind turbine; when the sun is shining you use the solar cells to produce the energy,” The Archimedes CEO Richard Ruijtenbeek said.

The Liam's blades are shaped like a Nautilus shell. The design allows it to point into the wind to capture the most amount of energy, while also producing very little sound. The inventor of the turbine Marinus Mieremet says that the power output is 80 percent of the theoretical maximum energy that could be harnessed from the wind.

    This Is The Call To Stand
    Every Country, Each Citizen, Promised Peace At The End Of Each World War, at The End Of Every War,

    We Must Honour Our Promise

    Our Enlightenment Is Empowered By Pure Unadulterated Gratitude

    For PEACE NOW
    WE NOW Give Thanks
    Thank You Thank You Thank You

    We Are Not Of fractions

    We are Refractions Of All Light

    I Give Freely All As Merit To All And Everything Discovering Our Truths And All Beings Freely United As Ultimate Good Expanding Limitlessly

    When We remove The Word People Or Person From A
    Sentence,
    A Homogenised Other Form seems to be produced,
    A Form which seems to be Falsely simplified,
    To The Point Where Worth seems Falsely dissolved, blames falsely attributed, Our
    Familial Connection seems to be Falsely dissolved,
    a false other on which it seems hate Or Love Can Be Pinned, without conscience,
    a being we seem to be able to separate from our GOODness Uniqueness, Difference Similarity
    This Is Our Unique Gift To Reality
    As Individually Complete Beings
    And Completely Individual Beings
    Although Supreme Being Is Simply The Removal Of the word other
    And With Knowledge Of Completion
    Without a Drop Spilled Nor A Fleck Lost
    To Be Cherished As A Father, Mother Cherishes Each Of Their Children, Yet All As

    ONE GLOBAL COMMUNIVERSAL FAMILY

    Wonderfully un real separation doesn’t Exist

    Wonderfully Real FREE Unity Does

    Simply Insert, A Real Person, Some Background, Someone’s Loving Son, Daughter, Father, Mother, Pillar Of The Community, Scared, Caring, Beautiful Being
    Before our judgement and You Are Awake Here Now In The Moment

    we weigh lightly our wrong
    We Weigh Heavily Our GOOD For Each Life Gives To All Others,
    Non Judgement Allows That Occurrence To Co Create, Peace Limitlessly

    Unlimited Our Gratitude, Unlimited Our LOVE
    Remember Nothing Belongs To Anyone But To All Life Simultaneously and Can Only Be Held By Giving It And Receiving It With The Gratitude Of Accumulative Complete Expansion Of Everything,

    Terror is a False Fear Of Seperation, That When Our Memory Is At Peace
    Reminds Us That We Are Sustained By The Same Air, Walk The Same Earth, Are Warmed By the Same Stars, Are Protectors Of The Same Precious Jewel, As One And The Same Communiverse

    Thank You Thank You Thank You
