Hello Fudogs

We have had geothermal generation at a few sites in the Volcanic area near Lake Taupo, New Zealand, over many years.

Initially there appeared to be only small problems.

Long term show that major problems do ensue, the major problems in New Zealand being:

1. Collapse of surface strata into the cavern caused by removal of live steam from below ground.
2. Waste water loaded with heavy metals, where to put this water is a major problem now.
3. Corrosion of pipework, turbine runners, valving, electrical equipment, and contamination of electrical insulators causing arc-overs.
4. Health of personnel affected by toxic gases and steam.
5. Health of plants, forest trees, grasses etc downwind for several miles of emissions.

Measures have been taken to re-inject the used water/steam, back into heated strata below, but that lowers the plant efficiency.

Those are a few of the problems in New Zealand

I understand that Iceland, Italy and other Countries with geothermal stations have experienced the same problems.

Kind Regards....
