Interesting, indeed. However, the sun has been a constant energy source since the beginning of life on Earth. We should be focusing on harnessing it instead of continually mining for coal, no matter how abundant it may seem to be. A combination of solar and wind energies should be the focus for renewable energy.
I highly doubt it, have you heard of coal ash? What will that go into? More landfills, it's something that cannot be hid and very hard to dispose of. Solar power is generally water based, so far to create sustainable power, the way to go is windmills.
