so i had this idea pop into my head:
if you tether an iceberg and tie it to the seabed with a pully... bear with me now! (polar bear?)
as the tide changes the pully rotates a generator
i read icebergs can have a displacement of around 200000 tones. this may be way off, i cant verify.
in the arctic circle tides go up and down about 3m twice a day to total travel is 12m
thats just vertical, tides also drift a long way. we ignore that for now, happy that it wont drift in front of a boat.
so if 200k tons force is applied over 12m per day, have i fixed the energy crisis?
why dont they apply this to massive ships that often sit for weeks at anchor waiting to unload? they can displace up to 600000 tons. even when sitting at port they are burning several tons of fuel per day just to keep the 'lights on'
