The turbine I have described sits on a concrete base about 2 metres
across and 1 metre deep. It requires no support wires of any kind.

roughly, from memory, about 4 tons of concrete?

1) She has the sand on site.
2) There must be lots of rocks about to reduce the need for importing
same.
3) Probably get away with 1T cement, use the excavated sand, pebbles
from local beach (OK, probably illegal) or nearby wall?

Doesn't seem like quite enough of a base to me, but there you go.


Again, height of mast, weight on top, (maximum power of wind against the
weight on top (x) leverage against bottom). Some years ago, I saw a
security fence that was broken by wind, about 20' high, with weight
distributed along that height. Put up by a crowd of messers, OK.
