    The Earth is now rising on new foundations.

    Soon, the Earth will belong to the People.

    Today solar home owners have become the major generators of solar energy for their towns.

    Example: Wildpoldsried, Germany now generates 400% more energy than it uses, because every home & barn has 100+ solar panels.

    This decentralized energy production has shifted power generating from the few to the many.
    From the 1% who own atomic energy plants, to the 99% who own 100-panel solar homes.

    This has shifted the energy generation, political power and income from the 1% to the 99%

    Once only the 1% of a town were able to become rich by selling energy to the people of the town.

    Now, thanks to decentralization of energy production, thanks to the building of millions of 100-panel solar homes in every town, Now the 99% can become a little richer, by generating all the energy they need for their lights, cooking, hot water, sauna, and electric cars. They then sell their surplus to their town electric bus systems, schools, factories and hospitals.

    By 2041, many homes will have 100 glass window solar panels, that means a glass house, that will generate 400% more energy than they need.

    So they will also generate money.

    Enough money to pay most of their mortgage to the bank.

    In this way solar home owners will become a little richer than those not investing in 100-panel solar homes.

    As more and more people catch on to the huge advantages of investing in 100-panel solar homes,
    as solar panel prices fall, and the quality gets better, eventually most new homes will be generating 400% solar.

    Glass has now given People the technology to generate all the energy needed to power every home on earth.

    Home owners once were naught.
    Solar homeowners are now all.

    How did this happen so slowly?

    People cooking fish on a sunny white sands beach in Italy, about 900 BC, invented glass, because the fire melted sand into glass.

    The next morning they found these melted sand chunks and sheets, that were translucent, beautiful, clear and sharp.

    They made glass knives.

    The ocean waves had washed the silicon rocks from the island, into clear white sand.
    People kept building fires on the sand and melting it into glass chunks & sheets.

    ( I am writing this from Helsinki, Finland, 7-11-16 ).

    Each morning they would wake up and find more and more melted sand, shaped like cups, sort of like bowls, or small colored glass windows.
    This gave them ideas and objects they could trade and sell.

    Some young people became fascinated by the melted sand and began building bigger fires to melt and make more glass objects.

    In 1839, Ed Becherel, age 14, decided to measure home much energy came from the sun.
    He mixed white sand and wood ash. He baked it in a large metal pizza pan, into a glass pie”.

    He then mixed more white sand with copper sand and baked that into a second sand “pizza”.
    He now had 2 large sand pizzas , one with a positive charge, and one with a negative charge from the different materials he mixed in the sand.
    He put them out in the noon day sun.

    He put a galvanic meter between the 2 sand/ glass pizza pies and measured the amount of energy he collected from the sun.
    He was able to record the amount of energy he generated from the sun, by using the glass pizza pies.

    The solar panel was invented by a 14 year old French boy.
    If science has follow his lead, by 1941 the world would have had millions of solar powered homes, and we could have avoided the rise of the 1%, the elite who controlled oil and destroyed our planets air.

    We now have once last chance to focus intensely on building millions of 100-panel solar homes and giving political power to the 99% who build solar homes.
