With dwindling oil supplies, pollution concerns and the ever-present threat of gas prices soaring again, talk of new and better ways to fuel our cars, heat and cool our homes, and power our factories has never been greater. What's more, the conversation is emanating increasingly from a source that's been surprisingly quiet until recently &#151; the oil companies themselves.
