To read science fiction ... many (or most) of our technologies are predicted in science fiction. I haven't read his books since I was a kid but
clearly his ideas have some merit ... and are also not feasible to develop today. Since the magma is in a plasma state it is subject to it's
surroundings. There is is a certain amount of rock that contains it. If a hole is pierced into this, you will create a volcano. The pressure is not
easy to block, because of the temperature of the magma.
If you drill with a laser you will consume more power than you generate, and the magma would melt it anyways.
The geothermal vents as pointed out by another poster are natures own mechanism for doing this. This is a better approach, to find areas that are
still rock but are super heated. Water can be piped down and then is turned into steam, which is sent through generating turbines, just like steam
power (and oil, gas, coal, and nuclear power all do).
It's a good idea, but expensive. Likely we will be forced to turn to this if / when our oil sources run out. Until then mankind is too stupid to
actually do something intelligent like switch to clean and renewable fuels. They'd rather get shot at.
