Performance and Potential Applications of Direct Expansion Ground Source Heat Pump systems for Building Energy

Omer A.M., University of Nottingham, UK

In the recent attempts to stimulate alternative energy sources for heating and cooling of buildings, emphasise has been put on utilisation of the ambient energy from ground source and other renewable energy sources. Exploitation of [...]

Technologies for Deep Reductions in Military Operational Energy Use

Brown R., Sharp T., Lindsey M., Kiser S., Andrews K., Lawrence Berkeley National Laboratory, US

The U.S. Pacific Command (PACOM) has begun a research program for Transformative Reductions in Operational Energy Consumption (TROPEC), which will identify, refine and validate technologies for reducing energy use in expeditionary military outposts. The primary [...]

Acoustic Power Recovery System for Thermoacoustic Cooling

Schwartz D.E., Garner S.R., Johnson J.R., Tuganov A.V., Palo Alto Research Center, US

In this work, we present a novel zero global-warming-potential, high efficiency thermoacoustic heat pump that can replace vapor compression systems for conventional air conditioning and refrigeration.

Passive and active Solar Systems for High Schools in Babylon- Iraq: Design and Economic Study

High Energy Density Supercapacitor Based on a Hybrid Carbon Nanotube – Reduced Graphite Oxide Architecture

Bekyarova E., Ramesh P., Jha N., Itkis M.E., Haddon R.C., Carbon Solutions Inc, US

We report a high energy supercapacitor device that utilizes hybrid carbon electrodes and the ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF¬4) as an electrolyte. The hybrid electrodes were prepared from reduced graphite oxide (rGO) and purified single [...]

Save Hawai‘i…Save the Planet

Barlow J., Power Alternative, US

Petrochemicals are quintessential ingredient in most all products, technologies, and conveniences of modern lifestyle, so it is imperative that we eliminate abusing it to fuel modes of progress, and transports. Power Alternative is scientific R&D [...]

Challenges in Thermal Energy Storage for Solar Power Plants

Wibbenmeyer L., Smith T., Craig J., Abener / Abengoa, US

The need for renewable and sustainable energy is clear. Concentrated Solar Power (CSP) is one means of power generation that is becoming economically viable to meet those needs. CSP however, does have limitations due to [...]

BioGenerator – a Novel Bio-Technology for the Conversion of Hydrogen to Electricity

Karamanev D., University of Western Ontario, CA

One of the promising applications of the H2-to-electricity converters is in the field of power smoothing and storage. The technologies currently considered for smoothing and storage have certain problems. The use of hydrogen as a [...]

Tailoring Pt-Alloy Cluster Nanoparticles for Enhanced Electrocatalytic Activity

Balu R., Roy Choudhury N.K. Dutta N., Elvin C.M., Hill A.J., University of South Australia, AU

Polymer electrolyte membrane fuel cell, PEMFC is an electrochemical energy conversion device that has the potential to be an alternative to internal combustion engines. However, the complexity and slow oxygen reduction reaction (ORR) kinetics on [...]
