Scientists Suggest Making More Clouds to Protect the Barrier Reef

Written by , on April 24, 2017

Researchers at the Sydney Institute of Marine Science and the University of Sydney School of Geosciences are exploring the possibility of making low-lying clouds off the northeastern coast of Australia more reflective in order to cool the waters surrounding the Great Barrier Reef.  Read more »

New Technique Could Double the Efficiency of Compressed Air Energy Storage

Written by , on March 30, 2017

An EU project, which is investigating the possibility of storing very large amounts of energy in underground caverns, has proposed a technique which could almost double the efficiency of storing energy of such systems.  Read more »

Turn up the Thermostat and Get a Fan for Most Comfort and Power Saving

Written by , on February 10, 2017

A university study has shown that thermal comfort, perceived air quality and symptoms of sick building syndrome are reported to be equal or better at 26°C and at 29°C, rather than at the common “set point” of 23°C, if a personally controlled fan is used.  Read more »

Powering Trains with Trackside Solar Panels

Written by , on January 12, 2017

Imperial College London and the climate change charity 10:10 have announced a project to investigate using track-side solar panels to power trains. bypassing the electricity grid so that the panels can provide power precisely when needed most. Although this sounds quite straight forward, it is not being done anywhere in the world.  Read more »

Concentrated Solar Heat in Developing Countries

Written by , on May 30, 2016

The largest energy demand in many communities is for producing heat, for example for cooking or water sterilization. Using electricity, if available, risks regular blackouts and high costs and wood contributes to deforestation and indoor air pollution.
Using concentrated solar power directly, without the need for expensive and complex components, is ideal for many developing communities energy needs.  Read more »

Electric Cars Could Reduce Temperatures in Cities

Written by , on March 23, 2015

Researchers have shown that replacing conventional cars with electric ones could not only cut emissions from cars but it could also lower emissions of carbon dioxide by cutting the use of air conditioning.  Read more »

Simple Change to Cement Could Reduce CO2 Emissions

Written by , on October 1, 2014

Concrete is a leading contributor to global warming, producing as much as one-tenth of industry-generated greenhouse-gas emissions. A new study suggests a simple way in which those emissions could be reduced by more than half while producing a stronger, more durable material.  Read more »
