The purpose of this work is to investigate whether the installation of a parabolic through solar thermal power plant technology for power generation is economically feasible in Turkish republic of North Cyprus (T.R.N.C). Since such [...]

Low-cost Transmission, Storage, and Integration for Renewable-source Energy: Hydrogen and Ammonia C-free Fuel Systems with Underground Pipelines, Salt Caverns, and Liquid NH3 Tanks

Leighty B., The Leighty Foundation, US

Solar and wind are the lowest-cost renewable sources, but are intermittent. New, low-cost transmission and storage infrastructure will be needed as we convert the world’s largest industry -- energy -- from fossil to renewable sources, [...]

Fabrication of Infrared Energy Harvester Using Electrically Small Particles

AlShareef M.R., Cui B., Ramahi O., University of Waterloo, CA

A novel structure based on electrically small resonators is proposed for harvesting the infrared energy and yielding more than 84% harvesting efficiency. The proposed harvester has been fabricated using nano-fabrication tools. Moreover, silver adhesion improvement [...]

Synthesis of Visible light Nanocomposites for H2 Production

Hussein A.M., Shende R.V., South Dakota School of Mines & Technology, US

Visible light active nanocomposites were synthesized by the sol-gel method using non-ionic surfactant as a template. Cr-doped ZrO2-modified coupled ZnO/TiO2 composite was thoroughly characterized for surface area, crystal phase, microstructure, elemental identification and band gap [...]
