ok guys, we've been fiddiling and fuming about all this nuclear reactors for the past few generations right? when all they essentially do is produce heat. this heat drives a turbine which in turn produces electricity ta da! as we all know, nuclear reactors can pose a very dangerous threat to the environment if not dealt with properly. but we still end up with all the radioactive waist which is really a big downside....... why dont we use another source of heat that we dont need to "create" we have at our disposal right underneith our feet some sereous heat! what if we build a thermo-electric generator underwater, where the crust is thin., i know this has some sereoulsy technical diffuculties. or even better, wat if we use these areas on our earths crust that are underwater and essentially build a hollow tube that submerges underwater toward all this heat. all this heat (esentially lava and such) would mealt the water that is right above it (no need to worry about how much water you need) i say you use this pipe and esentially guide all this steam up to the surface . but the real beauty of this idea is that, because you are putting all this "air" into a pipe that is underwater, and is open at the end. all this air rises through the tube right? but of course it builds up pressure at the top because the turbine is up top. because the water would want to reach equalibrium inside the tube and outside, you just need to get some air in that tube, and leat it build pressure. then with your turbine, you open the valve that is over its intrance where the pressurized air is, and generate electricity. although the generator cant be really big because you dont want too much air to escape at one seccond as to lose too much pressure within the tube. the exit flow of air must be less or equal to the ammount of air coming in from the bottom (under water) all this so you still have some pressure to work with -to drive the turbine- a picture would be so much more usefull to describe this. sooooo...... what do you think or am i just insane?
