A revolution of sorts is brewing in the clean energy field, with the emergence of fusion and low energy nuclear reaction" (LENR) energy. These processes, unlike fission reactions used in conventional nuclear reactors, need not emit dangerous radiation, nor do they produce radioactive byproducts. The fuel is plentiful and free. One pioneer in LENR is Andrea Rossi, an Italian-American inventor-entrepreneur ... who recently formed a venture to commercially market systems based on an LENR process he has developed. Many are understandably skeptical of Rossi's claims; yet he reports that he has a full-scale working prototype, delivering 1 MWatt continuous net output power, which is already seven months into a one-year acceptance test at a commercial client's site. Several observers have seen the system in operation, and have reported that it is working as claimed. On 25 August 2015, the U.S. Patent Office awarded Rossi a patent for his process. Given the potential importance of these developments, scientifically, economically and environmentally, we have been following progress in this area in earlier Huffington Post articles (HP#1) and (HP#2). "We foresee applications for central heating of commercial buildings, heat production for industrial processes and electric power generation. My dream is for domestic heat and power generation," [said Rossi]. "We have already obtained safety certification for our industrial plants. Domestic systems are still on course in the certification process."
