The Sun Flow solar system operates as a pre-heater. Its function is to
raise the temperature of the water going into the existing system.
Year-after-year your maintenance-free SunFlow system will go on
providing a substantial part of your hot water needs.
A. Cold water inlet: The cold water line which normally goes directly into
the existing water heater is diverted [...]
This cast epoxy impeller is designed to provide efficient performance on micro-hydro Pelton wheel water turbines. Power from water increases with head and increases with flow rate but is limited by pipe friction.
Maximum power for any pipe size occurs when the frictional losses in the pipe equals one third of the static head. Any increase [...]
Kinetic energy (movement) exists in the moving waves of the ocean. That energy can be used to power a turbine. In this simple example, to the right, the wave rises into a chamber. The rising water forces the air out of the chamber. The moving air spins a turbine which can turn a generator.
When [...]
