Unlike cold fusion, I can well believe more conventional fusion has a chance at success. But the engineering hurdles required to produce enough useful power to pump back into the system and maintain the reaction, and still have plenty of power for output to commercial use, are still huge.
And no, I don't think there's a "cold" equivalent. That's probably a good thing, though: If there were a workable "cold" fusion process, this planet probably would have stumbled upon it by some natural process, and blown this planet to Kingdom Come long ago...
