Earth Grid (improved) storage idea for Wind Turbines (not a joke):
Take say five or
six wind turbines, and group them around a common area. Connect them all to the same power grid -
then connect this common grid to a central, underground battery. The battery would be like a large building
buried underground - maybe with ceramic wall containment. Otherwise, it could be a standard lead-acid
or Lithium Ion battery. Or, use more
durable metals in a novel arrangement to store a large charge. The idea is that it would take several days
or weeks to charge up the battery, but it would discharge in the same amount of
time, providing a large power ‘buffer’ when the wind dies down. It could provide a consistent amount of
current. This would take up more land -
say around an acre for the combined turbines and central battery, but then could
all be fenced in for security.
The Earth Grids could be aggregated for higher currents
and voltages. There would be high
up-front costs involved. But steady
power outputs might then prove economical in the long run. A possibility worth investigating, it seems
to me.
