  • Ocean exergy and energy conversion systems

    Oceans store energy in the form of currents, waves, tides, heat and salinity that can help to alleviate worldwide demand for power and the global climate change threat. They also store a considerable amount of an isotope of hydrogen (deuterium) which takes part in the most promising fusion reactions. Exergy analysis can be applied to evaluate the work potential (extractable) of a resource. This ...

  • Establishment of sustainable water supply system in small islands through rainwater harvesting (RWH): case study of Guja-do

    Many islands in Korea have problems related to water source security and supply. In particular, the water supply condition is worse in small islands which are remote from the mainland. A couple of alternatives are developed and suggested to supply water to islands including water hauling, groundwater extraction, and desalination. However, these alternatives require much energy, cost, and concern ...

  • Operational data of the Star City rainwater harvesting system and its role as a climate change adaptation and a social influence

    The Star City rainwater harvesting system (RWHS) was featured in the December, 2008, issue of Water 21. The article highlighted that the RWHS has a 3,000 m3 rainwater tank used in water saving, flood mitigation, and emergency response. Since then, many news media, public officials, and people from both South Korea and abroad have visited the RWHS. In this paper, two years of the system's ...

  • Entropy generation metric for evaluating and forecasting aircraft energy management systems

    A general Entropy Generation Minimisation (EGM) technique is applied to analyse the feasibility of energy recovery from aircraft avionics via thermoelectric (TE) devices. In employing this approach, a suitable control volume definition is chosen to evaluate the impact of an energy recovery system on the overall entropy generation of the aircraft over a mission. Only those systems which are ...

  • Environmental impacts of ocean-energy systems: a life-cycle assessment

    Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

  • How to grow a solar energy garden

    Getting energy from the sun is a great idea. However, installing solar panels house-by-house is slow, costly and cumbersome, and downright inefficient if the goal is to bring solar to the masses. This problem troubled Paul Spencer after he built his own uber-efficient, custom solar home near Aspen, Colorado in 2004.  The engineer and serial entrepreneur wondered how he could replicate his ...

  • Solar Energy has Little Impact on Birds

    People are not worried about the pollution coming from the renewable energy sources, because most of them do not produce significant amounts of pollution. The supplies, the process of how the supplies come to the source and the demolishing machines used to erect these renewable energy sources are the true culprits wreaking havoc environmentally. For instance, older wind turbines have a negative ...
