>From looking at several reports, it appears that cold fusion cells produce some excess power in the range of 0.5~0.9 watts per cell. Now, since we are assuming fusion reactions and not chemical, than it follows that any one cell would have enough reaction mass even if shrunk to a very small size to last for years. That leads to two questions:
Do these cells need constant attention for every cell? How large an array of these cells can be built in how small a box? If the answer to the first is no, then CF 'batteries' become possible. And if the answer to the second is quite a small box, then practical power supplies can be made. Anybody? 'Beehive' type batteries maybe? Standing Bear
