because not many eruptions are not occuring. It will take some time for the crust to melt and a lot of pressure to build up. And we can instantly die when you come in contact with Magma from the volcano and the chemicals coming out being blasted into our atmosphere.

Good concept but almost imposable to use magma to create energy. There is a great amount of energy stored in magma, but what we need to think about is how to tap into the source that gave the magma it's heat. Can we do that? Yes I think so.
We drill water wells in a area around the heat source, looking for superheated water. Once we find some, we pump it out, flow test it, and re-inject it. By doing this we are testing our heat source to see if it will consistently superheat water. Now if it does then we have a very good chance we can build a geothermal powerplant in this area.
One example of this is Puna Geothermal in Hawaii. They pump water out of the ground and re-inject it. They put a tracer in the water to measure how long it takes for re-injected water to be superheated and then pumped back out. The results were 30 min! That confirms there is not a good superheated aquifer but a very good heat source. This very closely answers your question and goes along with my example.

Because pumping magma out of the Earth requires energy, and the amount of energy you'd have to invest would make any payoff negligible. Right now we can only exploit magma that's already close to the surface, which of course occurs in volcanic regions like Iceland.

Iceland gets a lot of Energy from Geothermal but then its very close to the surface the technology of drilling for Heat has quite a few challenges yet

Um....if that were even physically possible.....don't you think the Earth would cave in if you sucked out its insides?
I think you mean geothermal energy, but you worded it very oddly.The magma isn't sucked out of the planet.

It is a good and constructive idea.
There is a long list of easy alternative energy sources and if added, magma as energy source would fall at the lower end of this list.
yes i am amused with your idea.
good efficient thermocouple batteries could be used to tap this vast and unpredictable energy storehouse for good one day.
