Company History

After a variety of research and entrepreneurial experiences in the field of industrial and energy plant design, Andrea Rossi founded Leonardo Corporation in 1997, in Manchester New Hampshire -USA, a company specialized in planning and manufacturing plants and machinery for the production of energy from non-conventional sources.

Andrea Rossi’s earliest research on LENR and high pressure & high temperature nickel-hydrogen reactions dates as far back as to 1991 but most research at this time has been done partial time and after the founding of Leonardo Corporation. First in 2007, the inventor, Andrea Rossi, made the big breakthrough that came to refocus Leonardo Corporation to become a full time R&D company on LENR technology under the brand name E-CAT, short for Energy Catalyzer. Since then several patents has been applied for, tests, demonstrations and validations has been done and Licensing Agreements has been signed.

Now Leonardo Corp. performs its business in Miami -Florida -USA
