Becoming “Water Neutral”

Written by , on March 11, 2014

A number of companies and other organisations around the world, including CocaCola and Sainsbury's, have announced that they are striving to achieve "water neutrality". But how can a company like Coca-Cola, whose business is selling water, be water neutral? The term "water neutral" seems to suggest that the company is seeking to have zero net […]  Read more »

Drones to Collect Solar and Wind Energy

Written by , on February 12, 2014

New Wave Energy, an English company, has plans to build a high altitude aerial power plant, consisting of networks of unmanned drones that can harvest solar and wind energy and transmit it wirelessly to receiving stations on the ground. As sunlight radiates down to the Earth's surface some of its energy is absorbed into the […]  Read more »

Using Steam Engine Technology for Power Storage

Written by , on November 30, 2013

A group of Australian engineers has formed a company, Terrajule, to develop a novel energy storage solution. The Terrajoule system combines concentrated solar thermal energy, steam engines and an integrated storage system using an insulated pressure vessel. The concentrated solar thermal energy is used to produce steam. Since it is impractical to store steam for […]  Read more »

Falling Particle Solar Thermal Power

Written by , on September 17, 2013

Engineers at Sandia National Laboratories in New Mexico, and partner institutions, are using a falling particle receiver to more efficiently convert the sun's energy to electricity in large-scale, concentrating solar power plants. The falling particle receiver developed at Sandia drops sand-like ceramic particles through a beam of concentrated sunlight and captures and stores the heated […]  Read more »

Solar – a $77 billion Industry

Written by , on August 21, 2013

Bollomberg has created this short video of facts about the state of the solar industry. It emphasises how global solar energy capacity has soared in the past 5 years yet Earth's most abundant energy source still provides only a fraction of our total energy.  Read more »

Hybrid Solar-Wind Turbine

Written by , on July 12, 2013

SME McCamley Middle East Ltd, togeher with engineers at the University of Bath, have developed a new hybrid technology that integrates wind and solar power generation – the wind turbine blades are encased in an outer frame, which is topped with solar cells. The turbines are designed to be mounted on buildings and in built-up […]  Read more »

Nanocellulose – 2. Recyclable Solar Cells

Written by , on April 22, 2013

Georgia Institute of Technology and Purdue University researchers have developed efficient solar cells on cellulose nanocrystal substrates. The cellulose substrates and made from plants and can be easily recycled at the end of their life. To date, organic solar cells have usually been fabricated on glass or plastic. Neither of these is easy to recycle […]  Read more »

Sahara Forest Project Progress

Written by , on April 13, 2013

Back in 2008, we wrote about the Sahara Forest Project – a plan to use solar power and seawater desalination to produce renewable energy, food and water in an area of desert. As shown in this video, the first fully operational pilot plant has now been built.  A documentary about the people and progress of […]  Read more »

New Material for More Efficient, Ultra-thin Solar Cells

Written by , on February 13, 2013

Researchers at the Vienna University of Technology have discovered that a class of materials, called oxide heterostructures, can be used to create a new kind of extremely efficient ultra-thin solar cell. Professor Karsten Held from the Institute for Solid State Physics at Vienna University of Technology explained that "Single atomic layers of different oxides are […]  Read more »
