history main image

EarthLinked Technologies, Inc. was established in 1980 under the pioneering spirit of its founder, Robert (Bob) Cochran, P.E., an electrical engineer. His goal was to develop the simplest, most efficient means of using the solar energy stored in the shallow earth for heating water. The vision was based on the fact that almost one-half of the solar energy that strikes the earth is absorbed by it. That stored geothermal energy is a clean, local, renewable source that is free for the harvest.

Bob Cochran was an engineer in the management of an electric utility where he worked with the utility’s attorney, Hal Roberts (currently serving as EarthLinked’s Chairman of the Board), for ten years before they founded EarthLinked Technologies. Their entrepreneurial spirit drove the persistence and passion that is essential to the development and commercialization of new innovations in a mature market. Their professional and business ethic held the company and its distribution partners to a high standard that built a reputation of confidence and respect within the clean energy industry.

The passion, creativity and long-term dedication of the entire ETI team have enabled the company to develop significant renewable energy and efficiency innovations and satisfied customers in many countries. Those technologies have been shared and co-developed by a team of talented engineers and technical experts who have extended the inventions into products that are now operating in various applications and climates globally.
