Getting electricity from the volcano, that's a little strange. All I know is that it is from the heat of the sun or solar panels and the other is from water to generate electricity.
Now, from the volcano, I've only heard that in a few decades to be honest. How can El Salvador do this? This is quite a big challenge, but if they succeed, it will have a great impact for sure in the world of cryptocurrency. Let's see what happens about this news.
Let's take for instance the battery torchlight. The energy present in the cell is in a chemical state and when the switch of the torchlight is turned on, there's a change of state of energy from chemical to electrical. The volcanic mine simply works this way, the thermal or heat energy present in the volcano heats up water underground, which in turn creates powerful steam that help to spin the turbines and generate electricity. El Salvador volcanic mining of Bitcoin is a much more cheaper and cleaner alternative to the electric mining which is reported to cause greenhouse gas emission.
The technology for extracting electricity from a volcano is the same everywhere, but first hot water must be delivered to a heat exchanger. There are a lot of active volcanoes in America, but I'm not sure that they use these opportunities to the maximum.
"List of geothermal power stations in the United States" has very few temporary buildings and powerful geothermal power stations.
