New Advances in Renewable Energy Technologies.

Splitting water to create renewable energy simpler than first thought?

(PhysOrg.com) -- An international team, of scientists, led by a team at Monash University has found the key to the hydrogen economy could come from a very simple mineral, commonly seen as a black stain on rocks.



New solar product captures up to 95 percent of light energy.

(PhysOrg.com) -- Efficiency is a problem with today's solar panels; they only collect about 20 percent of available light. Now, a University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available light, and he plans to make prototypes available to consumers within the next five years.

New omni-directional wind turbine can capture wind energy on building rooftops.

(PhysOrg.com) -- Katru Eco-Energy, headed by founder and inventor, Varan Sureshan, has developed a new kind of wind turbine meant to capture the winds that fly in all directions atop big buildings, and unlike conventional devices, the IMPLUX, as it’s called, can capture wind from any direction as it stands; meaning without having to be repositioned or pointed. The IMPLUX achieves this feat by means of horizontal turbine blades that sit atop a vertical axis and are turned by wind that is pushed up through what Sureshan calls a "fluid dynamic gate."

Why Nuclear Energy Isn't Going to Power the World.

A quite interesting analysis by Derek Abbott, Professor of Electrical and Electronic Engineering at the University of Adelaide in Australia, concludes that nuclear energy isn't a very promising alternative to the fossil fuel based economy due to a number of factors.

New Artificial Leaf and Photosynthesis.

Yet another new breakthrough in low cost solar energy just made its debut, and this one is a doozy: a solar cell the size of a typical leaf, that actually creates energy the same way a leaf does: with photosynthesis. No, for real. You just park it in a bucket of water and it generates enough electricity to power household devices… eventually (more on that below). The announcement was made by the lead researcher on the MIT-based project, Dr. Daniel Nocera, who said, “A practical artificial leaf has been one of the Holy Grails of science for decades.”

The world can be powered by alternative energy, using today's technology, in 20-40 years

A new study – co-authored by Stanford researcher Mark Z. Jacobson and UC-Davis researcher Mark A. Delucchi – analyzing what is needed to convert the world's energy supplies to clean and sustainable sources says that it can be done with today's technology at costs roughly comparable to conventional energy. But converting will be a massive undertaking on the scale of the moon landings. What is needed most is the societal and political will to make it happen.

Breakthrough promises $1.50 per gallon synthetic gasoline with no carbon emissions

UK-based Cella Energy has developed a synthetic fuel that could lead to US$1.50 per gallon gasoline. Apart from promising a future transportation fuel with a stable price regardless of oil prices, the fuel is hydrogen based and produces no carbon emissions when burned. The technology is based on complex hydrides, and has been developed over a four year top secret program at the prestigious Rutherford Appleton Laboratory near Oxford. Early indications are that the fuel can be used in existing internal combustion engined vehicles without engine modification.

According to Stephen Voller CEO at Cella Energy, the technology was developed using advanced materials science, taking high energy materials and encapsulating them using a nanostructuring technique called coaxial electrospraying.

“We have developed new micro-beads that can be used in an existing gasoline or petrol vehicle to replace oil-based fuels,” said Voller. “Early indications are that the micro-beads can be used in existing vehicles without engine modification.”

“The materials are hydrogen-based, and so when used produce no carbon emissions at the point of use, in a similar way to electric vehicles”, said Voller.

The technology has been developed over a four-year top secret programme at the prestigious Rutherford Appleton Laboratory near Oxford, UK.

The development team is led by Professor Stephen Bennington in collaboration with scientists from University College London and Oxford University.

Professor Bennington, Chief Scientific Officer at Cella Energy said, “our technology is based on materials called complex hydrides that contain hydrogen. When encapsulated using our unique patented process, they are safer to handle than regular gasoline.”
