Between 7% and 14% water loss.  Unless you can find some hot dry
rocks near the sea-side, your chucking water away.

Oh bullshit!  What else are you going to pump down a
3-4 km deep hole, across and through a 500m X
500m X 200m slab of hot rock and back up a 3-4 km
hole in the ground?  And accepting a loss of
7% - 14% into the environment?  Paratherm perhaps?

That's exactly the sort of lunacy we have come to
expect from Watermelon Greens in this country.

You're delusional sonny.  In Australia, water is
not "convenient" and nor should it be cheap.
