Question:
What
about building underwater - wouldn't you lose a
lot of electricity - and wouldn't it be very expensive
to cross the oceans?
Key
Words:
underwater electricity transmission lines, profits,
global electricity grid, R. Buckminster Fuller,
Dymaxion Map, links, ground lines, costs, France,
England, Scandinavian countries
Answer:
Electricity
is already flowing in HVDC cables underwater in
a number of places. For instance, underwater links
connect France to England, Morrocco and Spain,and
the Scandinavian countries to Europe. Underwater
cables require extra protection, plus converter/invertor
stations at each end, so the costs are often triple
the typical overhead line expense.
The
underwater portions of the global electricity grid
would be relatively short, since most links are
across straits. GENI uses Buckminster Fuller's Dymaxion
Map to show that high-voltage tranmission lines
are primarily over land. There are relatively few
underwater linkages to be crossed: Bering Strait,
Gibraltor, Hormuz, Suez, Malacca and Timor.
