A few things you can do in Diigo - 240 views

Just used the 'invite to a group' feature for the first time. You can go to some of your diigo friends, and invite them to this group ;-}. It works like a charm.

Biofuels and Food Security should be a very important aspect of this group - 152 views

I agree that biofuel is a dead end, and in fact is perhaps worse than the disease. I will cross-post some recent articles I have found on biofuels and the scramble for African land (and land elsewhere...

Superconductor market set for explosive growth? - 134 views

I just bookmarked superconductors.org, which appears to be one of the better information sources on superconductivity (though I've not gone in depth). At least, it gives a balanced view, avoids extrava...

Hi Hans: Thanks for the reply. Sadly, the Diigo folks have blocked enhanced crossposting to multiple groups, which means its kind of a hassle for me to double post articles. I'm already posting most ...

EarthTalk: Do city 'congestion taxes' really help the environment? | csmonitor.com - 1 views

  • Jeff Johnson
     
    Despite increasing green awareness and steadily rising gasoline prices, Americans and other denizens of the developed world - not to mention millions of new Chinese and Indian drivers hitting the road every week - are loath to give up the freedom and privacy of their personal automobiles. But snarled traffic, longer commute times, and rising pollution levels have given city transportation planners new ammunition in their efforts to encourage the use of clean, energy-efficient public transit. One of the newest tools in their arsenal is so-called congestion pricing (also called variable toll pricing), whereby cars and trucks are hit with higher tolls if they access central urban areas at traditionally congested times.

Sweden Rolls Out New High-Speed Green Train on Old Tracks :: PNN Planet2025 News Network - 0 views

  • new ECO4 energy saving technologies have been installed, including a new permanent magnet motor that delivers increased propulsion chain efficiency and a "driver assistance system."

      This may be useful, but the emissions for trains are already low per passenger. It is just icing. We need to be investing in carbon capture and make all stations ready for the tech when it arrives.

Dead battery? Just refill it | The Car Tech blog - CNET Reviews - 2 views

  • davidchapman
     
    The Fraunhofer Institute is using a redox flow battery, a type of cell that uses two electrolytic fluids exchanging protons through a membrane. This process generates electricity. Although this type of battery isn't new, the Fraunhofer Institute improved the energy density, making it equivalent to that of a lithium ion battery.

Using CO2 to Extract Geothermal Energy - 2 views

  • Hans De Keulenaer
     
    Is the geothermal market about to boom? It is one of the more difficult renewables to harvest. It requires exploration to find good resources. It needs deep drilling which is complex. There is a risk for imcreased seismic activity which is unknown. But if all can be addressed, it offers baseload electricity. The only other renewable that does this is hydropower.

STUDY: U.S. subsidises fossil fuels 2.5 times more than renewables - Autoblog Green - 1 views

  • According to a new study that reviewed fossil fuel and energy subsidies for Fiscal Years 2002-2008 was just released by the Environmental Law Institute and discovered that the U.S. spends about two-and-a-half times as much on fossil fuels (mostly aiding foreign oil production) than it does on renewable energy.

Smart Plugs (TalkingPlugs) for Your Home - 1 views

  • Colin Bennett
     
    "Google's PowerMeter can monitor home energy usage in great detail as well but it generally requires that an electrician install a smart meter or a home energy display. LaMonica reported a couple months ago that IBM and the utility company Consert have been working together on a smart grid program where major appliances can be hooked up to controllers and can communicate with a meter in much the same way as these TalkingPlugs do. With this system, a person can view the data and even control appliances on the web as well. The end use is much the same as these TalkingPlugs."
