Here is a long article [link no longer available] that goes into some detail (very readable and not heavily technical) about cold fusion and a new approach to room temperature fusion that has been carefully checked by several different scientists and groups.
Right now, this new fusion generator is viewed primarily as a potentially useful source of radiation (e.g. for medical equipment). There is still much work to do to build a room temperature fusion device that generates large amounts of electricity. But this appears to really work, and it's one more weak signal of the emerging Energy Economy.
