A:
There are very strong basic reasons why the sorts of cold fusion which have been proposed won't work. We haven't heard of any reason to think otherwise.

Hot fusion of course continues to be essential when it occurs on the sun and dangerous when it occurs in hydrogen bombs. It's an open question whether controlled hot fusion on earth can be used as a power source. It certainly won't happen very soon, since the technical challenges remain huge.
