  • Development and performance evaluation of 0.16 m 2 solar point thermal energy collector compared with flat plate collector

    Renewable energy systems such as wind, solar and biomass are significantly more land intensive than traditional fossil fuels. Renewable energy increases diversity of energy supplies and can replace diminishing fossil fuel resources over the long run; their use in place of fossil fuels can substantially reduce greenhouse gases and other pollutants. Application of solar energy for domestic and ...

  • Thermodynamic analysis of an air solar collector

    The paper presents the experimental study of an air solar installation with a collecting area AC = 4.2m² and variable working fluid flow rate in the range 0.02÷0.06 kg/s. The experimental data are processed statistically through thermodynamic analysis, using energy (semi-empirical) and exergy methods. The aim of the paper is to establish the optimal air flow rate through this solar thermal ...

  • Energy use drops: It’s not just the economy

    We’ve been hearing a lot about a drop in energy consumption as a result of the economic downturn. In fact, US energy use per person declined last year to its lowest level since 1968. Economic activity and energy use are directly linked. But lately, several reports have noted that the economic slowdown is not the only reason energy consumption is falling. Aggressive energy efficiency efforts ...

  • Harnessing the Sun`s Energy for Water and Space Heating

    The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these "solar thermal collectors" use the sun's energy to heat water, space, or both. China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors ...

  • Can low-income housing be energy efficient and affordable?

    Residents of low-income housing need energy efficiency more than others, but are less likely to be able to afford it. How to escape the Catch-22? In Ann Arbor, Michigan, the local housing commission is completing floor-by-floor renovations in the five-story Baker Commons public housing ...

  • Dynamic exergetic performance assessment of an integrated solar pond

    In this paper, we present an experimental investigation of the exergetic performance of a solar pond integrated with solar collectors (with a surface area of 2096 m² and a depth of 2 m, and four flat–plate collectors with dimensions of 1.90 m × 0.90 m). A data acquisition device is used to measure and record the temperatures hourly at various locations in the pond. An exergy ...

  • Exergy analysis of a rock bed thermal storage system

    In this paper, a thermodynamic procedure is presented to analyse energy and exergy balances of a rock bed thermal storage system. The thermal behaviour is described by means of a control volume that includes three subsystems: the solar collectors, the fluid distribution system and the storage chamber. Solar-to-thermal energy conversion was obtained by means of a solar collector at a fixed airflow ...

  • A novel underground solar thermal heat storage unit cum heat exchanger for non air-conditioned buildings

    A novel passive space conditioning configuration is presented, integrating a Solar Collector System, Underground Storage Tank and Novel Heat Exchanger. This Underground Solar Thermal Heat Exchanger (USTHE) provided improved sensible heating/cooling of air by employing a Novel Heat Exchanger (NHX). The dynamic performance of the storage tank in USTHE is modelled using the finite difference method ...

  • Studies on performance characteristics of a solar parabolic trough concentrator with a variable area absorber

    The design of a suitable absorber that incorporates an efficient heat transfer augmentation technique is one of the vital parameters that affect the performance of a solar parabolic trough concentrator (PTC). The variable area absorber discussed in this paper provides appreciable augmentation in heat transfer without increasing the pressure drop materially and thus helps in enhancing the ...

  • On rooftops worldwide, a solar water heating revolution

    The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors to convert sunlight into heat that can be used to warm ...

  • Biogas production and potential from U.S. Wastewater Treatment

    How many wastewater treatment plants (WWTPs) have anaerobic digestion? How many are utilizing the biogas? What percentage of these facilities are feeding additional substrates into their digesters? How is the biogas being used — is it flared, used to drive process machinery, heat the digester, or injected into a natural gas pipeline? These are some of the questions asked of the ...

  • Novel fabrication technologies of 1D TiO
    2
    nanotubes, vertical tin and iron–based nanowires for Li–ion microbatteries

    We present the combination of anodisation, sputtering and electrodeposition processes as a novel technology to fabricate nanoarchitectured materials. Titania nanotubes are successfully fabricated using Ti foils and Ti film on Si wafers; by simply varying the anodisation parameters a 600–900 nm range of tube length and a 50–150 nm range of tube diameter can be obtained. Iron and tin oxides ...

  • Recapping the Debate Over Whether Low-Carbon Economies Are Good for Tech

    To be of any use, tech products need power from electrical outlets, stored chemical energy such as batteries and generators, solar collectors, kinetic energy like my emergency hand-crank radio/charger, or other means. As more global and local regions move away from fossil-fuel-based power to low-carbon renewable power, I wonder how my colleagues in the tech industry would weigh in on a debate ...

  • Opening the envelope on bearing vibration

    A sophisticated signal processing technique can help to pinpoint bearing failure at an early stage. Chris Hansford, Managing Director at Hansford Sensors, explains. Experienced operators can often tell if a machine is not working properly, on the basis that is does not ‘sound right’. The same principle can be applied – using modern electronics – to identify the exact cause ...
