Converting thermo energy into mechanical motion, how?

What are the easiest means of converting the heat in a live vacano
into mechanical motion and generate electricity? Assume there are
infinite amount of 2000 degree melted rocks pour from vacano, and
removing hardened rock isn't an issue.

I think you mean "volcano".


Easy. Any mechanism that converts heat into a fprce or pressure can be
applied to moving something a short distance and doing work. The rest
is just mechanical engineering.

Steam engines have been around a couple hundred years. They *still*
use them to convert the heat of a nuclear reactor into electricity.

When dealing with a live volcano, permanent structures are not
going to survive. Geothermal energy is common, where "hot rocks"
are close to the Earth's surface. You might want to do a search
for "geothermal".

Take exactly the same heat-exchange mechanism and steam-powered turbos
that are used in a nuclear power plant and put them in thermal contact
with the lava. (Assuming removing hardened rock isn't an issue, of
course.)

PD

Steam engine using heat from the lava, drill a hole and put a steam pipe in,
use a steam turbine to power an alternator to generate electricity.

Done.
