Cotter corp. starts water cleanup in old uranium mine - The Denver Post - 0 views

  •  
    "The owner of a defunct uranium mine leaking pollution along a creek that flows into a Denver Water reservoir has launched a cleanup as ordered, state officials confirmed Thursday. Cotter Corp. installed a system that can pump and treat up to 50 gallons per minute of contaminated water from inside its Schwartzenwalder Mine, west of Denver in Jefferson County. Water tests in 2007 recorded uranium levels in mine water exceeding the human health standard by 1,000 times. Elevated levels in Ralston Creek also were recorded. The Colorado Department of Public Health and Environment ordered the action. State natural-resources officials also are monitoring the mine, which produced uranium for weapons and nuclear power plants."

Moon Mined for Earth's Alternative Fuel? - 1 views

  • "Just 40 tons of this stuff has enough potential energy to meet the total U.S. electricity demand for a year." Does this mean we will be mining the moon for Helium-3 any time soon to fuel the earth? Probably not, since the cost to extract Helium-3 from the moon would be enormous and it would require "hundreds of millions of tons of soil" to "be processed to extract a ton of helium-3".

      Seems a long way off. I can't see it working before tipping points if we don't use the money for viables.

    Mining for helium-3 on the moon is being considered as another alternate fuel source.

Can Electricity Be Weighed in Gold? - Doing Business Blog - The World Bank Group - 0 views

  • On January 25th the sector experienced a huge shock when the state-owned electric utility Eskom informed the big mining companies that it could only provide for 50% of the mines’ usual needs for the months to come. The consequence? Mines had to be shut down. You don’t want your miners stuck hundreds of meters deep below the surface and see the light suddenly go off.

Mining Hydrothermal Vents For Renewable Electricity, Drinking Water - 0 views

  • The Marshall Hydrothermal Recovery System would use the heat from hydrothermal vents 7,000 feet under the sea to make electricity. Its temperature is incredibly high, hot enough to melt lead, but it does not boil because of the intense pressures at the depths where the vents are located. Superheated fluid would be propelled up through a through a (well insulated!) pipe to an oil platform located on the surface above the vent. The superheated fluid is carried by means of flow velocity, convection, conduction, and flash steam pressure as it rises and the ambient pressure is decreased.

  • The EU should de-politicise coal by providing a solution to the related socioeconomic issues, such as the difficulties of transition in coal mining regions. T o do so, the EU should broaden the scope and change the functioning of the European Globalisation Adjustment Fund, to make it into a flagship EU initiative that will support European coal miners who will inevitably be affected by EU decarbonisation. By devoting 0.1 percent of its post-2020 budget to this item, the EU could facilitate the elimination of a major stumbling block on its decarbonisation pathway.
  • Box 1: A back-of-the-envelope calculation of the EGCF budget requirements to support the coal phase-out Europeans employed in coal mining = 216,000 (0.07 percent of total) Assuming a 50 percent phase-out between 2020-27 = 108,000 jobs to be phased out (Fair to assume that part of the remaining 50 percent will naturally retire over the period) 108,000 / 7 years = 15,430 jobs to be phased out yearly between 2020-2027 Assuming financial support of €10,000 per worker = €154 million per year Total financial requirement for the coal-item of the EGCF between 2020-27 = €1 billion

Opinion | Nuclear cleanup regulation could put public at risk | Seattle Times Newspaper - 0 views

  •  
    "The weaknesses of federal regulatory agencies have been exposed by recent high-profile accidents. Guest columnist Tom Carpenter fears the Department of Energy will reduce its oversight of cleanup at the nation's nuclear waste sites. By Tom Carpenter Special to The Times PREV of NEXT Related Millions of gallons of oil gush continue to rush unabated from BP's mile-deep well in the Gulf of Mexico, and 11 workers are dead from the massive explosion that caused the biggest oil spill in decades. Weeks before this event, the news was dominated by the preventable explosion that killed 29 West Virginia coal miners. In both cases, the not-so surprising news was that the mine and the oil rig had abysmal records of safety violations before the explosions yet were still allowed to operate by the captive regulatory agencies. Where is the government accountability? It is the government's job to assure that ultra-hazardous industries operate safely and responsibly. Is nuclear next? The Department of Energy sits on the nation's biggest nuclear nightmare. Its inventories of highly radioactive and toxic wastes defy comprehension. Washingtonians are familiar with the DOE's No. 1 accomplishment, the Hanford nuclear site, which holds the lion's share of the nation's radioactive detritus. Suffice it to say that the escape of even a small fraction of such material into the environment would constitute a Chernobyl-sized catastrophe."

Amory Lovins on the Transition to Renewables & How They Enhance Security and Sustai... - 1 views

  •  
    "In the wake of the BP Gulf oil disaster, the natural gas explosion in Texas this month and the coal mine diaster earlier this year. It seems like public consciousness is finally shifting. While being green and supporting renewable energy was a good public relations move for the last few years, it now seems like a practical one as well to prevent disasters like these from occurring again. It seems like the mood is ripe for the transition to renewables and other sustainable energy technologies to begin in earnest. I had the chance to sit down with Dr. Amory Lovins, chief scientist and co-founder of the Rocky Mountain Institute, to talk about how the transition to renewables will make the U.S. energy system more secure and stable and where the country currently stands in that process."

Study says nuclear power isn't as "safe and clean" as Bush claims | Cleantech.com - 0 views

  • Nuclear energy doesn’t live up to its billing as the “emission-free panacea,” says a study from Pennsylvania’s Clarion University.
  •  
    According to a study from Clarion University, Pennsylvania, USA each step in the current US process of building and running a nuclear plant, from mining the uranium ores to disposing of the wastes, contributes to greenhouse gas emissions. Indeed, the article states that for nuclear power to be a feasible alternative energy source the entire process would need to be more efficient. This study gives a view on nuclear power which includes long standing ideals. The paper seems to offer an intermediate review on issues around the subject of nuclear, in the wider energy debate.

Peak Energy: Platinum Free Fuel Cells - 0 views

  •  
    Technology Review has an article on new fuel cells that don't require platinum - A Catalyst for Cheaper Fuel Cells. A new catalyst based on iron works as well as platinum-based catalysts for accelerating the chemical reactions inside hydrogen fuel cells. The finding could help make fuel cells for electric cars cheaper and more practical. Fuel cell researchers have been looking for cheaper, more abundant alternatives to platinum, which costs between $1,000 and $2,000 an ounce and is mined almost exclusively in just two countries: South Africa and Russia. One promising catalyst that uses far less expensive materials--iron, nitrogen, and carbon--has long been known to promote the necessary reactions, but at rates that are far too slow to be practical.

  • Heat pump water heater (HPWH) systems mine the energy content of air to produce hot water very efficiently (Figure 1). Depending on cold-water and ambient-air temperatures and on patterns of hot water use, heat pump water heaters do the same job as standard electric water heaters using two to three times less electric energy.
