smfen magnets - 1 views

  •  
    SmFeN magnetic material uses abundant rare-earth Sm element instead of expensive elements of Nd, Dy, Co, etc, and is the most cost-effective rare earth permanent magnetic material. Compared with the bonded neodymium magnet, the bonded SmFeN magnets has higher magnetic properties and lower prices. Moreover, curie temperature, corrosion resistance, and thermal stability of bonded SmFeN magnet perform much better than bonded neodymium magnet. Bonded SmFeN magnet as an alternative of bonded neodymium magnet has broad application prospects.

Ocean currents can power the world, say scientists - Telegraph - 0 views

  •  
    The technology can generate electricity in water flowing at a rate of less than one knot - about one mile an hour - meaning it could operate on most waterways and sea beds around the globe. Existing technologies which use water power, relying on the action of waves, tides or faster currents created by dams, are far more limited in where they can be used, and also cause greater obstructions when they are built in rivers or the sea. Turbines and water mills need an average current of five or six knots to operate efficiently, while most of the earth's currents are slower than three knots.

ESA - Observing the Earth - Understanding Our Planet - Arctic ice on the verge of anoth... - 0 views

  •  
    Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year. Envisat observations from mid-August depict that a new record of low sea-ice coverage could be reached in a matter of weeks. The animation above is a series of mosaics of the Arctic Ocean created from images acquired between early June and mid-August 2008 from the Advanced Synthetic Aperture Radar (ASAR) instrument aboard Envisat. The dark grey colour represents ice-free areas while blue represents areas covered with sea ice.

Inhabitat » Dancefloor generates electricity at London's first eco-disco! - 0 views

  •  
    Previously seen in the Sustainable Dance Club in Rotterdam, this is Britain's first exposure to such technology. The rest of the power needed will come from a wind turbine and solar energy system, with any surplus used to power private homes in the area. The club will also be installing the latest air flush, waterless urinals, low flush toilets and automatic taps to ensure maximum water saving plus less greedy air conditioning units.

Radical new vision of a cooler life on earth - Times Online - 0 views

  •  
    The global power industry must take the lead in making energy efficiency a way of life, says Jonathan Leake Six kilograms of carbon dioxide a day. If that sounds like little more than an obscure scientific measurement, think again. In the years to come it's a figure we may have to get used to. Why? Because, say climate scientists, that's the maximum daily amount of carbon dioxide each of us can generate if humanity is to have a chance of keeping the rise in global temperature below 2C.

Google announces plan to wean US off coal and oil - earth - 02 October 2008 - New Scien... - 0 views

  •  
    Internet search giant Google - sometimes criticised for the amount of energy its servers use - now aims to do for the power grid what it did for the web. Having conquered the market for web search by first simplifying how it is done and then linking advertising to users' search terms, Google Inc is now funding green technology and using its brand power to lobby for policy change.

Japan taps into power of volcanoes with geothermal energy plants - Telegraph - 0 views

  •  
    Japan has announced plans to build its first new geothermal power stations in nearly two decades in a bid to tap the nation's domestic energy sources. A string of geothermal power plants are to be developed by a number of firms keen to capitalise on the active volcanic landscape that spans the country, while the government is also currently compiling guidelines supporting the development of such energy sources. Home to 108 active volcanoes - ten per cent of the world's active volcanoes - Japan is in a prime position to tap into underground geothermal energy sources. As a nation with few natural resources, Japan has long been dependent on importing substantial quantities of crude oil and natural gas. The country's renewed focus on geothermal energy marks a desired shift away from its dependency on imported energy sources which has made it susceptible to increasingly volatile prices.

Energy from the wind is the best for Earth | Emerging Technology Trends | ZDNet.com - 0 views

  •  
    According to a Stanford University researcher, 'wind, water and sun beat biofuels, nuclear and coal for clean energy.' The scientist 'has conducted the first quantitative, scientific evaluation of the proposed, major, energy-related solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability and sustainability.' Wow! The researcher found that some sources of energy were 25 to 1,000 times more polluting than the best available options. Some of his conclusions make sense, some are controversial, but read more…
