Lucid Energy is a developer of renewable energy using hydropower. The company has developed the LucidPipe Power System which uses gravity to turn the movement of water into renewable energy. The company harvests an otherwise untapped resource, that is excess pressure in gravity-fed water pipelines. Their in-pipe hydro turbine uses the force of excess pressure in gravity-fed pipeline systems to generated power thereby not just generating power, but also helping reduce costs of installation of pressure reducing valves that are used by Municipal water delivery systems to take off the excess pressure created in the gravity fed pipelines. Currently the company is developing their second generation LucidPipe turbine design which is being claimed to utilize advanced manufacturing technologies, increase power output and operate across a wider range of pipe sizes and flows, and reduce capital cost.
