“Wind Lens” Claimed to Treble Turbine Efficiency

Written by , on August 31, 2011

Researchers at Kyushu University, led by Professor Yuji Ohya, say that they have discovered a simple way to make wind turbines much more efficient. By placing a ‘wind lens’ around the turbine blades, they claim that the power output of wind turbines could be increased up to three times.  Read more »

Foldable Solar Cells on Paper

Written by , on August 24, 2011

Researchers at the Massachussetts Institute of Technology have demonstrated a technique for printing solar cells onto a variety of cheap materials including untreated paper, cloth, plastic and even newsprint that has already been printed, The paper can be repeatedly folded and unfolded, or printed on, and the solar cells still work. The paper photovoltaic arrays […]  Read more »

Nano-tech Cable for Ultra-Efficient Grid

Written by , on August 23, 2011

It is estimated that the copper-based power grid leaks electricity at 3% per 100 kilometres of transmission. The Nobel Prize winning nanotechnology pioneer, Richard Smalley, showed that a weave of metallic nanotubes known as "armchair quantum wire" could carry electricity over long distances with negligible loss. It would be far stronger, lighter and, potentially, cheaper […]  Read more »

Study: Huge Potential in Storing CO2 from Biomass Power

Written by , on August 18, 2011

A study commissioned by the International Energy Agency has concluded that combining energy production from biomass with carbon capture and storage has the potential to reduce annual CO2 emissions by almost a third. According to Joris Koornneef from Ecofys, who conducted the study, "The combination actually removes CO2 from the atmosphere, The biomass extracts CO2 […]  Read more »

Sand Bricks Stronger Than Concrete & Sequester Carbon

Written by , on August 18, 2011

The Japanese company, TIS & Partners, has developed a construction material called CO2 Structure, which is claims hardens quickly, delivers 2.5 times the tensile strength of concrete, is made from cheap materials and sequesters carbon dioxide. High silicon content sand is put into an air tight mould that can be virtually any shape. CO2 is […]  Read more »

Default Meat

Written by , on August 16, 2011

The conventional wisdom is that it takes as much as 10 units of grain to produce one unit of meat with the equivalent nutritional value. George Monbiot has recently pointed out that we should be comparing the amount of land and water required to grow meat with the land and required to grow plant products […]  Read more »

More Efficient Spray-on Solar Cells

Written by , on August 16, 2011

Researchers at the University of Toronto have developed a technique to greatly improve the efficiency of nano-scale solar panels, or "quantum dots", which can be sprayed onto almost any surface to generate solar power. To date, solar cells based on this technology have been too inefficient to be practical. Conventional solar cells are tuned to […]  Read more »
