Progress in the development of rechargeable batteries through nanotechnology
Progress in the development of rechargeable batteries through nanotechnology A significant challenge for researchers in the field of rechargeable batteries is to construct batteries which can be charged and discharged quickly with only minimal energy capacity loss .
Nanostructures improve solar cell efficiency
Nanostructures improve solar cell efficiency Within the EU-funded research project N2P (Nano To Production) researchers work on nanostructured surfaces of solar cells.
Nano-tuned Solar Cells
Nano-tuned Solar Cells The sun has enough power to supply the whole earth with energy. But as long as renewable energy is more expensive than energy produced by coal or nuclear plants, solar energy won’t be first choice.
New solutions to reduce energy consumption
New solutions to reduce energy consumption Professor Claes-Göran Granqvist and colleagues at Uppsala University in Sweden have recently received about 2 million euros from the European Research Council to develop new materials making buildings more energy efficient.
The latest developments in nanotechnology for solar energy
The latest developments in nanotechnology for solar energy A researcher who is using nanotechnology on the active layer of organic solar cells is Dr.
Better Turbine Spacing for Large Wind Farms To help steer wind farm owners in the right direction, Charles Meneveau, a Johns Hopkins fluid mechanics and turbulence expert, working with a colleague in Belgium, has devised a new formula through which the optimal spacing for a large array of turbines can be obtained.
Hydrogen: The Green Fuel Of The Future
Hydrogen: The Green Fuel Of The Future Together the engineers worked on the fuel cell propulsion system by upgrading the air supply, integrating a humidification system, redesigning the hydrogen supply line and developing a hydrogen sensor concept.
Molten Carbonate Fuel Cells: an alternative and cleaner power supply for ships
Molten Carbonate Fuel Cells: an alternative and cleaner power supply for ships The research into molten carbonate fuel cells has it origins as early as the 1930s, Emil Baur and H.Preis in Switzerland experimented with high-temperature, solid oxide electrolytes.
SunPower Partners With Solar Ventures To Build 11.1MW In Italy Totaling 11.1 megawatts over 30 hectares, the development represents one of the largest solar power developments in the region. Construction on the plants will start this month and is expected to be completed by the end of the year.
Pushing the efficiency limit of solar cells further
Pushing the efficiency limit of solar cells further Some laboratories have achieved impressive efficiencies under concentrated sunlight. SunPower Corp. is much closer to the market. The California-based company recently produced a record-setting 24.
Michael Blunk: "These are the challenges to be faced by the wind power of the future"
Michael Blunk: "These are the challenges to be faced by the wind power of the future" Engineer and project manager Michael Blunk, Fraunhofer Institute for Wind Energy and Energy System Technology IWES, is one of the experts in the European project UpWind. The aim is to develop a new type of turbine.
When will solar power become competitive?
When will solar power become competitive? Competitive solar cells rely on climate, efficiency, material and production costs. The fluctuation of electricity prices from different sources and political climates both play a big part as well.
The Waltz of the Mirrors
The Waltz of the Mirrors 90% of the world’s population lives less than 2,700 km from a desert. If less than 1% of the world’s deserts were used to concentrate solar power, enough electricity could be produced to supply the entire planet.
Heat from the Centre of the Earth
Heat from the Centre of the Earth Geothermal energy has always been used by man, but it wasn’t until the late 19th century that geothermal energy was “rediscovered” and used on an industrial scale.
Grey Water to Heat My Home
Grey Water to Heat My Home Ecostiler “Energy efficient Community Stimulation by use and Integration of Local Energy Resources” is aiming to develop energy efficient communities thanks to the use of locally produced biogas and district heating systems.
The Ecologic Way to Paradise
The Ecologic Way to Paradise In the district of Hol, located west of Oslo, a church built in 1920 was renovated to become energy efficient for as little cost as possible, while respecting its status as a historical monument.
Power from the Islands
Power from the Islands In the spring of 2004, construction began on what is probably the most revolutionary project Högsåra in Finland has ever seen. This initiated a very special type of island adventure.
The End of Fossil Energy
The End of Fossil Energy Certain European cities are a step ahead when it comes to preserving the environment. For instance, thanks to innovative techniques and a more ecological way of life, the commune of Växjö, Sweden, could be on its way to becoming the first fossil fuel free city in the world.
Growing Ecologic Buildings
Growing Ecologic Buildings Reducing the energy requirements of buildings is an absolute priority in Europe. The energy demonstration project SARA has developed several public-access eco-buildings in France, Italy, Slovenia, Spain, UK and Uzbekistan.
Communist Heritage Turns Green
Communist Heritage Turns Green Climate change is on everyone’s lips these days and the European Union, having decided to reduce its CO2-emmissions by at least half by 2050, is no exception.
