Why don’t we utilize the heating power of volcanoes to make thermal electric power stations?

Question

Turning the generator makes electricity, generator is turned by turbine, and turbine is turned by force: the force is either water from waterfalls or steam. Boiling water creates steam. Water is boiled by coal, natural gas or atomic power. Why don’t we use the heat form volcanoes? This question is for scientists, who can think of a way utilize that wasted heat.

Answer 1

geothermal energy is well developed in places like Iceland. It doe cause large hot minerally laden lakes; but these have been turned into tourist attractions/spas

the question is not for scientists but economists and politicians. who do not add the cost of pollution and use of non-renewables into the cost of oil and nuclear.

The main problem is access to geothermal energy near to users, or the loss of long transmission lines.

Answer 2

I've been wondering about that myself for a rather long time. The main problem seems to stem from the unstable and unpredictable nature of volcanic areas. Conventional building materials and techniques cannot whitstand the strain placed on them in such a hostile environment, and therefore would jeopardize the life of workers. Also, the actual logistics of building a structure on top of an active volcano are complicated. Hope this helps.
