It was somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "IMM" saying

That's a wonderful way of wasting the precious resource of clean water.


It's the same water being pumped from tank to tank. Pay attention.

Being driven by mains water. In your own description.

Read it again. No waste water. pay attention!!!!!!!!!!

You could have a large tank at high level and one at low level. The mains
water turns the genny to produce power to heat a thermal store of water.
The genny turbine would have another pump on the same shaft. This pump,
pumps water from the low tank to the high level tank. When the high tank is
full the water from the high tank is released to turn the genny and flows
into the lower tank. Start all over again. You are getting the power to
raise the water free ( the water companies pumps in fact).

You're still wasting water; either from discharge into waste from the
driving turbine or, if that's discharged into the lower tank, then
pumped up to the upper tank to refill the lower tank. Either way you
have a surplus of a tankful of wasted water. Water that could have been
used to hold your head under.
