Take a bunch of molten iron (enough that it will go however deep) and let it percolate down through the earth's crust, leaving a huge hole. Let the iron cool and throw water down. When the water hits the now solid but hot iron(from the mantle below the thin layer of crust) steam is expelled. Harness
the steam atop the hole and use it to generate electricity.

Isn't this a normal geothermal well, but less complicated/
possible? |
|
| |
Except this could be used anywhere, not just in active volcanic areas |
|
| |
Maybe you could just leave the iron cold, and use whatever you were going to heat it up with to make the steam. |

"Take a bunch of molten iron" - which would cool and harden on the bottom and form a container for the remaining iron, however much you started with. You're suffering from Bad Science here, boy (girl?). |

I'm not altogether sure that molten anything would leave a channel behind it as it sank into the ground. But if it did, a better approach would be to use nuclear fuel rods. They would have the double advantage of being heavier than the materials in their path, and providing their own heat as they melted down. |
|
| |
Plus if you started them on the moon and dropped them onto earth, they would be going pretty fast when they hit. |
|
| |
Really fast...maybe enough to create nuclear yield if any actually survived the atmosphere? Figure out how to shapecharge a nuke and your tunneling needs are solved. |
|
| |
so you want to use energy to heat iron to the melting point, pour it on the ground and let it melt a hole, then pour water down the hole to get some energy back? I've heard some wasteful ideas, but this takes the cake. |

OK, so the whole thing would supposedly be heated by the mantle, right? Wrong. The only reason Geothermal works in some places is that the crust is thin enough there, or there is a pocket of magma working its way up. Drilling a hole at some ran |
