Huge investment for infrastructure will be needed. However it might be worth a while. I want to see how it evolves, although it is clear that without government funding or support it will be almost impossible.
Thinking that if humans have gone to the moon, taken pictures of Mars and beyond, anything can be possible. However, this technology sounds as science fiction at first impression. I would like to know more of it, although I guess such an undertaking might require outrageous investment sums, that could be gone down the drain if it does not work. Just think about all the R&D necessary to manage equipments at high temperatures and very hostile environment at 12 miles under our feet!!!
I am thrilled by the solutions suggested by Bruce and G T. However, how can long term use be assured if these vents are affected by inner earth movements (I imagine the earth is always moving and it could affect the operation if a vent is obstructed in any way)?? The other barrier to overcome, the transmission from ocean located generation to an on-land grid. Similar concern as the offshore wind power has. Anyway I think you've got a tremendously good idea. Good luck.
Well, to Dr James Scuderi, it would be pretty interesting to know what types of Free Energy are there, and how does the scale factor you mention affects the cost, with all respect I would like to know more about your point of view. I could understand it from the point of view of the inherent transmission and grid costs, in order to serve an populated area; am I right?
About the DC vs AC I once saw a program that said that DC has its advantages, but for control and safety mishaps, AC was more reliable. However you'll never know, it was in the time a battle between Westinghouse (AC) and Edison (DC). Most times is all about politics. Free market is sometimes ignored.
Very interesting. Although I might say that the penultimate paragraph has a mistake, I would suggest the oil would be used as biodiesel feedstock, and the organic feedstock would be for ethanol production, and not the other way around as it is mentioned. It would be great that these type of projects have a stronger financial support, given their contibution to the planet and society.
