The LENR processes have produced excess energies for long enough periods to be utilized by known techniques, however inefficient. With high energy fusion many technical problems would have to be addressed to utilize the excess energy. Materials would be a major technical hurdle.

Someone has made “excess energies” for enough hot water to take a shower or heat a house? Who might that be?
As for the hot fusion folks....they have a long, long wait ahead.
