Cob: Oklahoma thoughts and concerns

[toswink]

I think in the back issues of Mother Earth News like in the Seventies.
There is alot on this subject.
Look into cooling water at night time.
One person actually found ice forming in the storeage just by allowing water
to flow over plate exsposed to nighttime air.


This is allittle off topic but could be of interest.
Also effects of small voltages on clay etc.
