Engineering Associates, Inc. (EEA) was founded in Marion, Massachusetts in 1988 as a commercial venture to more effectively promote the work of Ocean Arks International. Susan B. Peterson, previously an employee of OAI, became EEA's first president. Co-founder John Todd preferred not to serve on its board, but was involved as an "ecological designer". EEA designed and installed a wastewater plant to remediate septage lagoons at Harwich, Massachusetts (see below). Work began in 1988, and the system became operational in 1990. EEA developed several other projects, using transparent water columns for treatment units in its "solar aquatic systems". Patents for processes relating to solar aquatics were filed under the inventor names of John Todd and Barry Silverstein in 1988 and 1991, and granted to EEA. EEA registered the trademark "Solar Aquatic" specifically for waste treatment tanks with transparent water columns. Living Technologies Inc. Todd also co-founded Living Technologies Inc. (LTI), an ecological design, engineering, and construction company, in Burlington, Vermont. It was incorporated as a company on October 26, 1994, in the state of Florida. Some of the personnel involved in Living Technologies, including president Michael Shaw, had connections to OAI and to a prior company called Advanced Greenhouse Systems (AGS) which had been established in 1989 by William Rapp, also in Burlington Vermont. Two patents for Ecological Fluidized Beds (EFB) were filed by John Todd and Michael Shaw in 1993 and 1995. The patents were granted to OAI in 1996 and 1997. EFBs were used in the design of what were increasingly referred to as living machines. In 1997, Living Technologies Inc. sought a second round of funding, which it obtained from Tom Worrell. In 1998, there was considerable reorganization of the company and its board. Worrell assumed ownership of the company in 1999 and acquired the rights to the original patents for Todd's "Living Machine". As of December 2000, in an out-of-court settlement, Worrell obtained the sole right to use "Living Machine" as a proprietary term. Worrell's company went through a number of name changes and relocations. Worrell Water Technologies, LLC of Charlottesville, Virginia currently holds the registered trademark for the name Living Machine. Worrell Water Technologies has redesigned Todd's original systems and patented a number of new technologies since 2002. John Todd Ecological Design Inc. In 1989, Todd incorporated "John Todd Research and Design" in Falmouth, Massachusetts. It later became "John Todd Ecological Design" (JTED). Through this
