  2. Ocean thermal energy conversion - Wikipedia

    en.wikipedia.org/.../Ocean_thermal_energy_conversion

    Diagram of a closed cycle OTEC plant. Closed-cycle systems use fluid with a low boiling point, such as ammonia (having a boiling point around -33 °C at atmospheric pressure), to power a turbine to generate electricity. Warm surface seawater is pumped through a heat exchanger to vaporize the fluid. The expanding vapor turns the turbo-generator.

  3. Mist lift - Wikipedia

    en.wikipedia.org/wiki/Mist_lift

    In closed systems, the expense of the exchangers represents the largest cost of the OTEC plant, with a 100MW plant requiring 200 exchangers the size of 20 foot shipping containers. [ 9 ] In 2010, Makai Ocean Engineering was contracted to construct computer models to evaluate whether a Mist lift power generation plant would be competitive with ...

  4. Osmotic power - Wikipedia

    en.wikipedia.org/wiki/Osmotic_power

    Similar to the open cycle in ocean thermal energy conversion (OTEC). The disadvantage of this cycle is the cumbersome problem of a large diameter turbine (75 meters +) operating at below atmospheric pressure to extract the power between the water with less salinity & the water with greater salinity.

  5. Oscillating water column - Wikipedia

    en.wikipedia.org/wiki/Oscillating_water_column

    The PTO system is the second main component of an OWC device. It converts the pneumatic power into a desired energy source (i.e. sound or electricity). The PTO system design is very important to the efficiency of the oscillating water column. It must be able to convert airflow going both out of and into the collecting chamber into energy.

  6. Thermodynamic cycle - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_cycle

    Because the net variation in state properties during a thermodynamic cycle is zero, it forms a closed loop on a P-V diagram. A P-V diagram's abscissa, Y axis, shows pressure (P) and ordinate, X axis, shows volume (V). The area enclosed by the loop is the net work done by the processes, i.e. the cycle:

    Some Americans feel they have no choice but to get the care their doctors recommend, even if their insurers deny it. That can result in massive bills.

    After firing Robert Saleh following a 2-3 start, the Jets are again taking drastic action amid a woeful season by firing GM Joe Douglas on Tuesday.

  9. Deep water source cooling - Wikipedia

    en.wikipedia.org/wiki/Deep_water_source_cooling

    Cornell University's Lake Source Cooling System uses Cayuga Lake as a heat sink to operate the central chilled water system for its campus and to also provide cooling to the Ithaca City School District. [3] The system has operated since the summer of 2000 and was built at a cost of $55–60 million. It cools a 14,500 ton (51 megawatt) load. The ...
