GM to build electric motors for next-gen hybrid | Green Tech - CNET News - 0 views

  • build electric motors for a hybrid vehicle platform due in three years
  • To the extent that a (gasoline) engine is core, these motors will be core
  • GM opened its own battery pack manufacturing plant last year because it considers that technology, too, to be core to its strategy.

Physicist develops battery using new source of energy - 0 views

  • have been able to prove the existence of a "spin battery," a battery that is "charged" by applying a large magnetic field to nano-magnets
  • In the future, the new battery could be developed to power cars
  • The new technology converts the magnetic energy directly into electrical energy, without a chemical reaction. The electrical current made in this process is called a spin polarized current and finds use in a new technology called "spintronics."

Commission pushes ICT use for Energy Efficiency - 0 views

  • These technologies are expected to reduce total carbon emissions in Europe by up to 15% by 2020. ICT can not only improve monitoring and management of energy use in factories, offices and in public spaces but above all help make people more aware of how they use energy.
  • The ICT sector itself is responsible for 2% of carbon emissions in Europe: 1.75% resulting from the use of ICT products and services, and 0.25% from their production
  • Results from trials in a number of Member States show that using smart meters can lower energy consumption by up to 10%
  • ...3 more annotations...
  • It will also call on the ICT sector to lead the way by setting itself concrete targets to become more energy efficien
  • The Commission also announced a new public consultation to establish a common base for commitments to and claims of improved energy efficiency.
  • Voluntary ICT Sector commitments to targets and deadlines for CO2 and Greenhouse Gas emissions (GHG), and energy efficiency/consumption

2.2 million Australian homes to get free insulation - 0 views

  • Insulation may not be as sexy as solar panels or wind turbines, but it’s an important tool in reducing our dependence on fossil fuels.
  • The Australian Government is stepping up its commitment to the environment by installing ceiling insulation in 2.2 million homes— for free. The Government will also increase the rebates for solar water heating from AUD$1000 to AUD$1600.

Saving Gas: Pneumatic Hybrid Engine Is Much Cheaper Than Electric Hybrids And Almost As... - 0 views

  • Although the fuel saving achieved by the pneumatic hybrid is not as large as that of an electric hybrid, it still amounts to 80 percent of the latter. In return, the price-performance ratio is distinctly better.
  • The new engine concept has aroused the interest of several major motor companies and automitive suppliers, who have obtained information on-site. Some of the ideas of the new concept have already been patented

A Ship That Floats On Bubbles | Got2BeGreen - 0 views

  • The bubbles travel along the hull, reducing friction and thus, increase gas mileage. Since ships are one of the largest consumers of diesel fuel in the world, so this idea is meant to get some attention along with some other ideas like boats attaching a giant wind turbine or adding parachute-like sails on the ship to increase efficiency.

Slicing Up Silicon for Cheaper Solar - 0 views

  • It has recently started shipping its first panels to select customers. This spring the company will begin production of solar panels at a factory built to produce 25 megawatts of solar panels per year.
  • This approach saves money because the total costs of the molded plastic, other extra materials, and added manufacturing steps still are lower than the cost of the additional silicon used in conventional solar panels. Solaria also reduces costs by using manufacturing equipment already developed for the semiconductor industry, thus avoiding expensive customized equipment.

Abu Dhabi's solar venture - 0 views

  • . Masdar, the oil-rich emirate’s $15 billion renewable energy venture, and Spanish technology company Sener on Wednesday announced a joint venture called Torresol Energy to build large-scale solar power plants in Australia, Europe, the Middle East, North Africa and the United States.
  • The irony is too rich to leave unsaid: A leading oil producer invests billions in carbon-free energy while a leading consumer of fossil fuels - the United States - continues to subsidize Big Oil while while offering only tepid support for green technology
  • Torresol plans to build solar power plants using a technology it calls a Central Tower Receiver system. It’s similar to technology used by competitors like BrightSource in that fields of mirrors called heliostats focus the sun’s rays on tower that contains a receiver. In this case the receiver is filled with salt which when heated vaporizes water to create steam that drives an electricity-generating turbine. The company says it intends to have 500 megawatts of solar electricity online by 2012.
