Researchers from Spain’s Universidad del Pais Vasco and Euskal Herriko Uniberstitatea have developed a compact heat storage system which uses phase changes in a type of paraffin to store the heat energy. Read more »
Scientists from Tohoku University in Japan have developed a new type of energy-efficient flat light source based on carbon nanotubes that has about one hundredth of the power consumption of an LED. Read more »
The world’s first coal-fired power plant with carbon capture and storage has been opened in Saskatchewan, Canada, but the value of the demonstration is being seriously questioned by environmentalists. Read more »
Winds 300 to 600 metres above the ground are, on average 5 to 8 times as strong as those at the surface.
Altaeros, a four-year-old company in Massachusetts, has developed its Buoyant Airborne Turbine (BAT) to take advantage of these stronger, more consistent winds. Read more »
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 »
Magnum Energy is proposing to export electricity generated by wind farms in Wyoming to Utah, where the energy would be stored as compressed air in caverns in underground salt deposits. It would then be used to transmit energy as required to Los Angeles. Read more »
